Parties Passion Pregnancy

"It's my only one, so be careful with it okay?"

"Yeah no problem, this will work perfectly."

Brad accepted the stage mask from his cousin Michael, the black and silver leather mask glinting in the sunlight.

Brad's friend Tim was organizing what he called a 'costume kegger' for tonight (friday), so Brad was borrowing his cousin's mask. Michael was a small-time theatre actor in the city, so when Brad heard he was coming up to visit, he made his request.

"Gotta say, I never heard of a costume party for high school graduates." Michael said with a cocked eyebrow.

"My buddy Tim can be pretty prolific sometimes." Brad replied sarcastically.

Michael had stayed the early afternoon, and now he was on his way out, so Brad saw him to his car and then went back inside as he drove off. Brad went straight to his bedroom and set his borrowed mask on his dresser, then opened all the drawers to see what kind of clothes he had that would make him incognito for the party. Tim had said specifically to come dressed in a way that no one will recognize you.

As he mulled over his decisions, his sister Tracy came by his room, then stopped and peeked her head in his doorway, long hair flooding down from her head.

"Hey, could you tell mom when she gets home that I've gone to Maria's house for the night?"

Brad looked up and glimpsed her in her social clothes, which rode the line between slutty and not-slutty.

"Yeah, sure thing."

"Thanks Brad! What're you up to tonight?"

Brad regarded her, she wore her undyed brown hair unadorned today; usually there was some sort of elaboration. Brad was in paranoid mode tonight though, not wanting to risk his identity by broadcasting his presence, so he fibbed hard.

"Might end up at the forest park with Dennis and that group. Not sure yet."

"Cool, I'll be there tomorrow, Maria and I are going hiking."

"Right," Brad said, his mind on other things, like disguises. He heard Tracy padding down the hall as he considered his options.

Much later that night, Brad stood at the side of the living room of Tim's parent's place, watching the twenty or so people talk and laugh and drink and dance. Everyone was wearing some sort of costume and mask, which, except in the extreme cases, quite effectively hid everyone's identity.

"Here it is bro," Tim said from beneath his Batman mask, "the great party of the year."

"May they continually get more and more epic." Brad said, lifting his plastic cup of beer to clack against Tim's cup.

"Am I supposed to not know who is at my house?" Tim said with a mischievous grin.

"Yes! It's 12:30, and nobody knows who anyone is. Well, except Kara," Brad said, gesturing vaguely toward the center of the room. A blonde girl who wore basically nothing besides a mask, displayed her rib and upper arm tattoos shamelessly, grinding on some guy that she didn't know, and giggling drunkenly.

"Kara notwithstanding," Tim said with a roll of the eyes, "I take your point. People are going to be very friendly tonight, and it's my fault!"

"All your fault dude, it's a great idea!" Brad said, draining the rest of his beer before skirting the party to get to the kitchen for a refill from the keg.

A girl who Brad had seen around that night was just topping off her beer at the keg in the kitchen. Her highlighted auburn hair was done up in elaborate curls, and she wore a black t-shirt with the midriff cut off, exposing her flat belly, which had an indeterminate tattoo barely peeking out of the waistline of her pink skirt. Her face was covered by a flowery mask, and she had cat ears in her hair. She wore hot pink lipstick which matched her skirt.

Brad adjusted his black masquerade mask and backwards baseball cap that he never wore, and tugged at his brand new polo. Brad never wore polos. He had tried his best to go incognito for this party, to fit the theme, and it seemed to be working, as no one but Brad seemed to have recognized him. For that matter, he hadn't recognized but two or three people tonight.

The music was loud, even in the kitchen, so when Brad went over to the girl in the cat-ears, he smiled when he caught her eye, and mimed having a dance together. She smiled and coyly acquiesced. She had pretty green eyes underneath that mask.

They went into the living room where everybody was dancing just as the song changed to a slower hip hop song. This was grinding music, and everybody made use of it. Brad watched as every pair around him began different magnitudes of grinding on each other, and when he looked back to Cat-Ears, she sidled up to him and pressed her whole body up against him, gifting him a taste of her scent, before backing off and dancing in front of him. Her movements were sinuous like a snake, her hips sidling and rocking. He danced closer to her, but she turned around before he got to her, and as he came up to her, she bent over as she backed up against him, pressing her ass against his crotch. This made his dick twitch, which he was sure that she felt. She twerked herself against him before hinging back up at her waist, so that her whole body settled back against him.

you can check here He grasped her upper arms as she came against him, and danced with her, her head turned so that he could feel her breath against his lips.

The song ended all too soon, and the dancers broke up for a moment. Immediately, Cat-Ears took Brad's hand and pulled him toward the kitchen. He allowed himself to be led, but he was surprised when his guide took him through the kitchen and out the back door. He began to get an idea about what was happening.

As soon as they were in shadow around the side of the suburban house, the girl turned round and came up to him, but he was ready. He slipped his hand around her waist and pulled her against him, their lips meeting and pressing. They were both short of breath after a couple of minutes when they broke apart.

The girl looked to either side; the alley toward the street was blocked by a privet hedge, and the way they came was deserted. The coast was clear.

She got down on her knees and her fingers grasped his belt, fumbling with the buckle, which he helped her with. He was getting excited, his dick hard in his pants and a bright tightness in his chest. An unknown girl was about to blow him.

Finally his pants were yanked down, and his cock sprung free, bobbing in the cool night air. There was a bit of a moon on the cloudless night, so Brad could see the girl grinning before she grasped his moonlit cock and kissed the underside of it a few times before capturing the head in between her lips. She held the tip in her mouth and flicked it with her tongue before sucking more of him in, and bobbing her head on him. He sighed in satisfaction as her slippery mouth sucked on his manhood, leaning back against the siding of the house, feeling the vibrations of the music through the plastic. They were there for what seemed like forever, but was probably less than ten minutes, Cat-Ears slurping and sucking away at him, and Brad just leaning back and enjoying the experience.

Suddenly, they heard voices and the slam of the back door, and shadows passing in front of the light from the back windows could be seen.

The mystery cat-eared girl pulled his dick from her mouth with a pop, and stood up hurriedly. Brad managed to fold himself back into his pants and do up the button before Cat-Ears grabbed his arm and pulled him toward the front of the house.

The high hedges extended out from the side hedgerow that separated the party house from the neighbor's house, and due to some inventive trimming over the years, a little niche in the hedge accommodated a little stone bench and a tiny wrought-iron table. This niche was hidden from both the road and the front door.

Perfect.

The girl hurried to the spot and turned to meet Brad as he came in after her. Again, she pressed her length against him and kissed his lips, which he returned enthusiastically.

When they came apart, the girl took her arms from around his neck and laid them on his chest before speaking low and in a whisper to him.

"Do you have a condom?"

The bright burning core of his arousal grew within his chest.

"No," Brad replied in an equally disguised voice, "but I'm clean. Trust me."

The girl hesitated in thought for only a split second before turning around and hitching up her skirt as she bent over and put her hands on the stone bench.

She wasn't wearing panties. Her smooth, alabaster ass was lit immaculately by moonlight, and Brad was taken aback by its visceral beauty and plump shape.

He popped open his pants button and let his still-hard cock flop out again. Spitting on his hand, he smeared it over the head of his still-damp cock and stepped up behind Cat-Ears, gripping his shaft as he guided it into the shadows beneath her shining ass cheeks.

He located her wet tunnel entrance, and pushed into it, feeling her vagina stretch to accommodate his intrusion. She bit off her moan as he worked back and forth in her slickness, pushing deeper every time until his lower belly came up against her tight butt.

She turned her head to look back at him, the moon shining on the flowers that composed her mask, turning all the skin he could see into quicksilver. He saw her lips spread in a grin, and her teeth caught her lower lip in their grasp as she pushed her lower portion back against him, an additional centimeter or so of him sinking even further into her.

Brad was extremely turned on, now that he began to fuck her. He hadn't gotten laid for over a year, and having anonymous sex with a girl who he may or may not know at a party was something extremely erotic that he had never done before, so he was fighting desperately to last a little longer. She was warm and tight for him, and met each of his thrusts with her own, turning her head back around to face forward while she held herself in position for his thrusts.

The front door banged open, and loud voices came with multiple footsteps on the stoop and in the grass. Brad stepped back for balance as Cat-Ears pushed back against him, his back ended up against the inside corner of the hedge with the mystery girl standing awkwardly right in front of him, her back arched severely to keep his penis inside her, but still poised to run.

Three dudes walked past toward the alley, not one of them bothering to look into the hedge niche. Brad hardly dared to breathe, feeling the girl's breathing held too. A moment later, they smelled pot smoke drifting toward them, so the group was occupied.

Cat-Ears sighed out her breath, and turned her head toward him, her eyes flickering behind the mask.

"Hurry and finish," her voice came in a low whisper.

Brad nodded, resuming his strokes in the new position. He had a thought, and brought his arms in front of her, placing his right palm on her bare belly, and his left arm slid up beneath the hem of her shirt, grasping a titty with no bra to stop him.

He could hear her breaths, irregular and sharp, reacting to his cock spearing into her. That, combined with the handful of ample tit, the feel of her flat belly beneath his palm, and the tightness of her snatch enclosing his dick was enough to push him over the edge.

So taken by the event, he didn't once think of pulling out of her.

He held his breath as the first clandestine burst of cum spurted out of him into her pussy. He gripped her hard and gasped as his second rope was shot up into her, the full realization of what he was doing beginning to steal into him.

With a reluctant grunt, he pulled out of her, his remaining ejaculate shooting into the grass by their feet. Cat-Ears was breathing heavily still, and as he pulled out, her weak knees shuddered, and a little groan escaped her. He let her go, and she stumbled over to the stone bench, catching her breath. As she leaned, the moonlight could not illuminate her pussy lips, hidden as they were by the shadow of her ass, but Brad distinctly saw a stream of pearly fluid fall between her legs, sparkling in the moonlight.

She stood up straight, and pulled her skirt down before turning to face Brad. He saw her midsection and the one boob he had gripped in the low light before she pulled her shirt down.

"Sorry, I-" he began to whisper, but the girl pressed her palm over his mouth and leaned close.

"Birth control," her husky voice said in his ear. He sighed in relief as she pecked his cheek.

"That was fun," she said briskly, and hurried out of sight, the front door of the house opening and closing once.

Brad blew his breath out of his mouth as he tucked himself away and fastened up his pants. He decided to go around to the backdoor, to keep further secret his encounter with a random woman. He still had no clue who that girl was.

The group that was smoking pot was still there, and among them was Tim, his dark knight mask giving him away.

"Yo, hit this a few times bro." Tim said, holding out a half a joint, which Brad took and hit before passing it along.

"Gotta say, Tim, this party might be the best idea you ever had."

"Better than last year's woods kegger?" Tim asked.

"Not much can beat that party," the tall guy with a Zorro mask said.

"Well, I didn't get laid at that party." Brad said slyly as his turn in rotation came up. Tim, who passed to him, hung his mouth open and laughed disbelievingly.

"You got some already??" he all but yelled. At Brad's casual nod, Tim pumped his fist in the air once.

"Nice!"

As they were smoking, they heard the back door open, and an anonymous couple rounded the corner and stopped abruptly when they saw the smoking group. With embarrassed excuses, the boy and girl backed around the corner again and disappeared. Brad grinned because he knew what they were looking for.

"Yessssssssss this is exactly what I wanted to happen here! The costume party worked!" Tim said.

The whole group laughed.

"God only knows who got laid here tonight!"

-4 weeks later-

As Brad turned the corner, he ran straight into his sister Tracy as she came out of the bathroom. They both staggered back against the walls as something white clattered to the floor, falling from Tracy's hand.

"Sorry, I didn't see you," Brad said, bending to pick up what she had dropped.

"Give me that!" Tracy said with vehemence, a wild look in her eye as she snatched the piece of plastic from Brad's hand and stomped off to her room.

"Ooookay then," said Brad, at first dismissive, but taking a second look down the hall in concern.

He and his sister had never been especially close, but he still had an idea of how people functioned. Unrestrained anger usually meant that she was unsuccessfully dealing with something important.

Usually he would just ignore his sister if she was being irrational, but something made him turn and follow her path to her room. She was laying on her bed, and looked up as he came in.

"Sorry I yelled at you." Tracy said, her body language apologetic.

"What's wrong? What is that?" Brad asked, gesturing at the tapered plastic tool next to her on the bed.

Tracy fingered the piece of plastic for a second before saying something unintelligible. Brad stepped closer, "What did you say?"

"It's a pregnancy test, okay?" she bit out, her face twisted into anger, which immediately fell to distress. Realization came over Brad.

"Tracy, you're pregnant?"

She nodded, her eyes on her bedspread.

"Who's the father?"

Her head shook back and forth. Brad felt fury rising in him, that some guy could knock up his sister and then split town. He sat on the side of the bed and gently grasped his sister's shoulder.

"Tracy, who was it? I'll hunt him down for you and-"

Her hand came up and grasped his arm, and her watery eyes made contact with his valiant gaze.

"No, please. I mean, don't go looking for him. He's gone."

Brad cocked his head and blinked. With a sigh, Tracy continued.

"I had sex with him before he moved. Out of state. I really liked him and we hadn't gotten a chance to hit it off, so I slept with him on the night of his move."

"And you let him- well, you know. Seal the deal?"

Tracy rolled her eyes, "I am on birth control. It just didn't seem to work that night. Plus I wanted it to be special for him."

Tears were welling in her eyes again, and Brad pulled her into a hug, realizing more of the situation. After a moment, he let her go and looked at her.

"Have you told mom yet?"

She shook her head.

"Hey Trace, you won't have to go through this alone. Mom and I are here to help you, even if the baby's father isn't."

He tried to affect an aura of reassurance when she looked at him with her now tear-streaked face. It must have worked, because she threw herself into his arms again and he heard her sniffle.

"Thanks, Brad." her muffled voice came.

After leaving her room, Brad realized that this is why people should be close to their siblings. He felt like he had been of some use there, even if it was just being there for her. It felt good.

-12 weeks later-

Over the next few months, Brad and Tracy connected as siblings, growing closer all the way siblings do. They started doing things together, things they never would have considered doing together before, like certain video games, socializing, and even hiking, which Tracy loved to do.

Her belly began to show at the end of her third month, which Brad noticed when Tracy came out of her room one morning with her sleep shirt on, which was pushed out slightly by her belly.

"Sorry Trace, but I don't think there's any getting around it. You're pregnant."

Tracy shoved him with a mock angry face before grinning.

"Okay funny guy, you'll be the one helping me change diapers here in another six months, so keep talking."

They were going hiking that day, so the first hour of the day was getting ready. It was the beginning of autumn, so they both wore long sleeves for the beginning of the hike, which always ended up tied to their packs by the time noon came around.

Looking around for a clean hoodie, and finding his old yellow one on the top shelf, he pulled it down by the sleeve and pulled it on, but something about the fabric was bound up in the side under his arm. A little twisting and pulling seemed to fix it, so he forgot about it.

Tracy came into his room, her pack in her hands, "Ready to go?"

"Yup!" he replied, grabbing his ready pack off the floor and grabbing his hiking boots.

The hiking trail began at the northern end of Forest Park, which was a campsite/nature area just outside town. The trail led from there up into the mountains, but Brad and Stacy only hiked into the foothills; going into the mountains was a multi-day affair.

It was a beautiful day with only partial cloud cover, but they still surprisingly found Forest Park to be all but empty.

"Looks like it'll be a quiet walk today," Tracy said as they got out of Brad's car.

"Well that just means we will have to make our own noise," Brad quipped.

Tracy laughed before bending over to stretch her legs. Brad took a double-take at his sister's ass displayed in all its glory for his admiration. His jaw was falling open in yearning before he caught himself and wrenched his eyes from the sight and gathered up what they were hiking with.

The trail was for atvs and hikers for the first ¼ mile, then the atv trail branched off, leaving the hiking trail to continue up into the foothills. Every year the government lays fresh gravel on the main trail and tends to erosion wherever it may crop up, so the trail is well-maintained. Intermittent forest gives way to rocky heights the higher you go.

The siblings made conversation in spurts; it's nice to talk, but simply hiking together it's its own experience too.

"So I changed my mind about Franklin, I don't like that boy name anymore. I've been leaning toward Benjamin, I kind of liked it when I thought about it last night."

"Still set on Crystal for if it's a girl?" Brad asked.

"Oh yeah, I love that name. What do you think about Benjamin?"

Brad shrugged, his face expressing his ambivalence.

"It's not for me. But, it's not my kid, so it's your decision."

Tracy looked over at her brother, "Yeah, but your opinion matters to me."

"Really?" Brad said, returning her look. She stopped in the trail, cocking her head.

"Yes! Brad, I'm gonna have a baby, and I don't know- I mean, the father is out of the picture. Even in the past few months you've been doing everything a boyfriend should be doing for his pregnant girlfriend, like being there for her and paying attention and talking about the baby's future…"





Her voice trailed off as she thought about it, then she looked back up at Brad with a twisted expression.

"You're kind of like my boyfriend now."

Brad started to laugh, but then thought about it, and felt the same expression cover his face.

"No offence, but eww."

Tracy's face burst into humor, laughter rolling from her mouth as she stepped toward him and hugged him. Brad smiled and returned the hug, glad his little sister was laughing.

"Don't ever stop being funny, Brad!" she said.

"I promise."

They resumed their hike, coming out of the forest into the bright sunlight amongst the rocky landscape. It wasn't long before Brad called a break to take a layer off and take a load off their legs. They slung their packs to the ground and Tracy immediately swept off her long sleeve shirt, her t-shirt riding up over her belly, which was distinctive now against her toned body. As Brad gathered his hoodie, he saw a bit of tattoo peeking out above her waistline, which he had never noticed before.

"Hey, I didn't know you got a tattoo!" he said.

Tracy looked down at the tattoo, "Please don't tell mom! I got it last year…"

"I won't tell anyone. What's it of?"

Tracy looked uncomfortable, shifting her weight and folding her arms.

"I'd… rather not say. Its very embarrassing to say it in front of family."

Brad shrugged and nodded, unconcerned, but some vague memory file was triggered, one that he couldn't put his finger on.

He pulled off his hoodie and gathered it up into a bundle he could pack away.

"Hey," Tracy said, coming over to him and crouching, "something fell out of your hoodie."

She stood up next to him as he turned and looked at what had been in his hoodie, to see the mask he had borrowed from his cousin all those months ago, for the costume party.

"Oh I forgot about that thing, I have to return it!" Brad said.

Tracy looked deep in thought, staring past the black frilly mask in her hand.

"I've seen this before, but I can't…"

Slowly, her eyes widened, and her mouth dropped open as her memory kicked in. The sun illuminated her surprise perfectly as she slowly turned her head to look up at Brad, who wondered at her expression. He was about to ask, when she finally spoke.

"Wh-where did you get this mask?"

"It's Michael's, I meant to return it but I forgot. What's the big deal?"

"No, I mean, what are YOU doing with it?"

"One of my buddies hosted a masquerade party a few months ago, and I wore that mask."

Tracy's eyes blinked rapidly, looking like she was in distress, "Were you wearing a baseball cap and a polo shirt?"

Brad, focused on her distraught expression, didn't catch on to how she might have guessed what he was wearing at Tim's party, "Yes I was! How did you guess?"

The mask fell from her hand as she backed away from him, her expression becoming positively mortified. Her hand clasped her belly as she looked at him.

"Are you okay??" Brad asked, bewildered by her behavior.

"You… you were the one… the one that…"

"What's wrong, Trace?" Brad asked, thoroughly concerned.

Tracy looked at him with a mixture of emotions all vying to use her face muscles to express themselves.

"Brad, I was at that party, the masquerade party at Tim's. I wore a black shirt, a mask made up of plastic flowers, and cat ears in my hair."

The way she explained things really threw reality in Brad's face; it all dawned on him at once. He looked at her with wide eyes, which slowly looked down to her noticeable belly.

"Oh. Oh no, no, no…" he said, backing away from her, which didn't work; his foot caught on loose rocks and he tumbled over backward, luckily falling where there were no rocks. He laid there for a minute, just breathing, looking at the blue sky, and trying to wrap his head around what had just been revealed.

He remembered the sheer eroticism of dancing suggestively with a girl he didn't know, and then being led outside and given a very skillful blowjob… And then...

He sat up, and looked at his sister, "That was YOU??"

Tracy nodded, her face still a panoply of expression. They looked at each other for a few moments, each processing what had happened, the mask laying in the dirt between them. Tracy crouched and sat on a boulder by the side of the trail and broke the silence.

"I guess you weren't really at the forest park that night, huh. Why'd you lie?"

Brad scoffed, "Because I wanted to keep my anonymity. Sure did work."

He looked back up at her, "Guess you lied about going to Maria's too."

She nodded, "For the same reason."

"And you didn't sleep with a guy who was moving away."

"That was just the cover story."

Brad started to smile, and then a grin broke out. Tracy looked like she tried to resist it, but the same happened to her, and before they knew it, they were laughing like hyenas, scaring up a flock of little birds from the trees from where they came.

After their laughter died down, Tracy shook her head before speaking.

"I'm still trying to wrap my head around this. Who knew my brother was so smooth at parties."

Chuckling at what he thought was a jibe at him, Brad suddenly realized that it wasn't the usual sisterly banter. He looked up and saw Tracy looking at him with a half smile on her face, sort of distracted.

"Yeah, well, you know. Like most of the guys there, I was looking around for something."

"You found it, alright," Tracy absently traced her nails across her pregnant belly, before getting to her feet and stretching her arms, causing her shirt to stretch across her chest, giving Brad a fine view of what his sister's body looked like underneath those clothes. His dick shifted in his pants, beginning to grow at the sight. Brad was almost horrified; he had never gotten a hard on while thinking about Tracy, she had always been his sister, outside of his erotic realm.

But now…

"Tracy, I'm-"

"Can I tell you something Brad?" Tracy asked abruptly, to which he nodded.

Tracy picked up her backpack, pausing to look at the mask, before striding through the grass into the woods. Brad followed, grabbing up his own pack and his mask.

A few trees in and she set down her pack again, looking around at the sunlight coming through the trees in beams. Then she turned to look at him.

"That night was the hottest night of my life, I had never had a more erotic experience. Now that I know that it was my brother in my-- well, at first I was disgusted, but then-- ugh, I'm not saying this right!"

Brad was listening, trying to get what she was trying to impart, "Take your time."

Her eyes found his and her jaw worked as she thought about something. She then clenched and unclenched her fists before walking over to him.

"I thought it was incredibly hot that whoever I fucked that night had such potent sperm that it cut right through my birth control," her voice was low and sultry as she looked up at him from beneath her brows, "the more I thought about it though, the more glad I am that it was you there pumping into me from behind," her eyes fluttered as her memory overcame her, but just for a moment. Her hand grasped at Brad's shirt.

"Was that night good for you too?" she asked, looking into his eyes.

Brad's cock was rock solid, and he exhaled, nodding slowly as he thought about it. Tracy grinned in a way he hadn't seen before, at least from her, as her grasping hand fell and took the filigreed mask from his hand and reached up to strap it onto his face.

"I think we should re-enact that night. Right now."

Brad dropped his pack into the grass and pushed her hand out of the way as he undid his belt buckle. He was completely on board.

An excited giggle came from Tracy, and she got to her knees in front of him as he fished his cock out.

"Oooh," she said as she grasped it with one hand, "It looks even better in the daylight!"

Brad groaned as she licked up his shaft, and then closed the head of his cock in her mouth. He laced his fingers behind his head and just stood there, letting his sister play with his tool and taste his pre-cum. He couldn't believe that he wasn't completely grossed out by this, after all the woman currently gagging with most of his cock in her mouth was his sister! But he wasn't grossed out in the least, in fact after the initial surprise of discovery, he was quite turned on by the series of events.

He looked back down at her as she popped his now-slick cock out of her mouth and got one leg under her to stand up. Brad quickly offered her his hand, helping her to her feet.

"Ugh thanks," She said, undoing the buttons on her jeans, "I'm really starting to notice the weight of the baby nowadays."

She slithered out of her jeans, her panties coming with them, and when she stood back up straight, Brad couldn't help but gasp at just how hot her body was; the curve and swell of her hips supporting the bulge of her lower belly made him surge with need inside.

And just beneath the hem of her shirt, was her tattoo, a stylized version of a specific organ…

"Is that a uterus tattoo?"

Tracy smiled and nodded, stepping closer to him and wrapping her fingers around his cock, "Yes it is."

She leaned against him, and spoke against his mouth, "I have a breeding fetish."

Her hand swept around his shaft and lightly grasped his balls, feeling their contours and weight. She slid her head beside his and he felt her breath on his ear, "Mmm, so this is where my baby came from."

Brad was getting frantic, what with the stimulation she had been giving him. She must have seen it in his eyes when she backed away again, because she immediately turned around and stuck her ass out, leaning forward against a handy tree. She looked back to encourage him, but Brad was already coming up behind her.

"I'm already- ugghhh!" she was interrupted by his cock finding her already wet entrance and slipping inside, a look of distress/pleasure washing any previous expression from her face.

"Yeah, you're already wet for me," Brad said after a sigh. His hands grasped her ass as he bottomed out in her, his entire length being held in her embrace. Briefly he marvelled at how hot and wet and tight his sister was, and then he got to work.

He pulled out almost all the way and then pushed back in, watching his slick tool disappearing into his sister's body until her butt cheeks squashed against his hips and lower belly. He established a steady rhythm, their heavy breathing and light wet slaps the only sounds.

Tracy's had faced forward again as he began to fuck her, but now she turned her head again, her eyes catching his.

"Harder," she hissed with need.

Brad obliged, beginning to slam against her, and picked up a little speed. A frown crossed her brows, and her eyes dropped, watching his midsection pummel her body.

At that moment, they both heard voices from the trail.

Brad froze, and Tracy gasped. When they confirmed that they weren't imagining things, Brad's dick left Tracy's pussy, and they sprawled in the grass, peering toward the path, their breathing rustling the grass in front of them.

Three guys with full pack came into view, and hiked past without even a glimpse in their direction.

"Wow, what a re-enactment!" Brad whispered, which caused his sister to burst into suppressed laughter and slap at his arm.

"Shut up, they might hear us!" she whispered with a grin.

this With a glance at the passing trio, no more than 30 feet away, Brad went into risky mode.

"Turn on your back," Brad said, and Tracy gave him a scandalized look before glancing back at the clueless hikers, now passing their position about 10 meters away. She quickly rolled over, her shirt riding up to expose her belly, which was hardly noticeable while lying on her back, and kicked her pants off of one foot. He crabbed over on all fours, keeping his dick out of the dirt, and got on top of Tracy, who spread her legs for him and angled her hips up to accept him in.

One last glance at the hikers moving away from them, and he sank back into her, their breaths heavy, and began to piston in and out of her. Her hands reached up to clasp around his neck as she slid back and forth on the grass from each thrust, girlish squeaks escaping her. Her eyes were looking at his, and he loved what he saw there in their green seas: simple, basic, personal lust as he plowed a furrow toward the natural end to their pleasures.

"Ughh," he grunted as his interior muscles began to coax forth his seed, "Trace, I'm gonna-"

Her legs wrapped around his moving waist, her ankles crossing at the small of his back.

"Give it to me, please!" she exhorted, her breath hot on his face.

He jerked as his first burst of semen rushed out of him, his sight dimming as the heights of physical pleasure dominated his mind. Tracy bit her lip and moaned as she felt the hot flood of his fluid fill her insides, her heels digging into his lower back as she tried to pull him deeper into her. Spasms wracked his body and groans rattled his throat as her tight embrace milked the rest of his load out of him, and he collapsed in her arms, panting into the grass beside her. Tracy wrapped her arms around his back, holding him to her as she stared at the trees above her, rising into the cloudless blue sky, feeling his cock still twitching inside her.

Finally, he got his arms under him again and pushed himself up, looking at his sister beneath him with an exhausted expression.

"Wow," was all he could manage.

Tracy smiled, "Wow is right, You came hard!"

He nodded, pushing back so that her arms and legs slipped off of him and he sat back on his heels, his slick dick shrinking visibly. She sat up on her elbows.

"I don't think any boy has cum that hard for me." she said, having seen his orgasm close-up, and honestly failing to remember any time that someone she slept with had cum harder for her.

He shrugged, still catching his breath, "What can I say," he gestured to her midsection, "my baby is in there."

Tracy felt something bloom in her chest, and her eyes began to fill. She got to her knees and knee-walked into his arms, gently grasping his mask and slipping it off his head, his features unadorned and true, their lips meeting in a passionate, loving kiss. The longer it went on, the more time slowed; they created and occupied their own little bubble of temporal space.

But everything must end. They ended their embrace sadly and got up, cleaning themselves off as best as they could before dressing.

"Gonna be a long walk, after that exercise," Brad said, shouldering his backpack and then holding hers up for her to slip into.

"Yeah, I always feel bow-legged after a good fuck," Tracy said, and they walked back toward the trail, her pace a little wide until she got used to walking again.

"You know Brad, I wasn't lying when i said I'm glad it was you who knocked me up," she said, her eyes on the trail.

"I didn't think you were lying," Brad said.

"It could have been some asshole, you know. Or I may never have found out who it was, and I was going to have to raise a kid by myself."

"Well, now you don't have to. I'll be there."

She looked up at him, saw the earnest truth in his eyes, and tears of happiness welled in her eyes again.

She couldn't keep a smile from her face as they walked together, hand in hand down the trail. For the first time ever since she found out she was pregnant, Tracy felt downright joyful about her future again. She looked up at Brad to find him already looking at her, and they both grinned stupidly at each other.

Brad used a hand to brush off her shoulder, "You've got grass stains on your back, how are we gonna explain this to mom?"

Tracy wasn't worried. They would think of something. They were a team now.
