"I think I love sucking too," Emily smiled, and gave his cock a final lick. The shaft sprang and shivered like a plank of wood.
"We'll give you lots of lessons in it - if Jennifer will ever stop. Hey," Nathan tapped his sister’s shoulder. Jennifer whined and lifted her face, her eyes opening slowly like she'd been waken up from heaven.
"What...? Oh. But I'm not done yet," Jennifer's pouting lips and chin oozed with the combined juices she'd lapped up from Emily's fertilized box. Emily's legs shivered at the sight. Nathan coaxed her to come closer.
"I've got something better for you both right here," he said, waving his stiff cock at his horny sister. Jennifer smirked and took the bait, even playing along as if hypnotized. Sauntering like a panther in heat, she crawled up Emily's body.
"Must have it..." she intoned, stopping only when her face hovered above Emily's. "Oh,” she said, “What a sexy little thing we have here. Let me have a taste," Jennifer pressed her lips to Emily's, and the eager girl opened her mouth for her. This time their tongues danced together, both girls excited to swap and taste what juices the other had.
Nathan kept moving, but Emily only knew what he was up to when Jennifer held her cheeks in her hands and groaned.
"Ohh, Nathan..." She moaned, her eyes glancing over her shoulder. "What are you... ohh shit...!" Jennifer tensed and groaned. Her brother was entering her from behind. The older cousin's hips settled against Emily's, their legs skewed apart in such a way that let Nathan have his choice of them both. Their mounds ground together, and Emily felt each jut and thrust of Nathan's blows into his horny sibling.
Nothing in Emily's sexually innocent life compared to it. Jennifer gasped and moaned, her fingers digging into Emily's sides for any support she could get. Their breasts mashed together - Jennifer wasn't given any choice as Nathan pinned her there. Every deep thrust delved deep into Jennifer's belly, the bulge so big that even Emily felt it.
Every so often Jennifer pressed her lips to Emily's, but soon enough the girl could barely muster the concentration. Her face contorted and her brow rose, and a dozen shades of ecstasy passed over her as swiftly as her brother's deep strokes. Soon enough Jennifer began to tighten and shake atop of her innocent cousin.
"Oh bro - oh fuck, fuck, fuck!" Jennifer's whole body grated along Emily's, their combined sweat letting them slide as if oiled. Emily watched her cousin's mouth open and close, her orgasm seizing her chest till no more words came. And then, as Nathan's hips relentlessly plowed into his sibling, Jennifer shuddered and jerked in quiet climax.
Hips grinding, pussies mashing, the girls endured Nathan's expert thrusts together. Jennifer hid her face in Emily's shoulder, her voice gone to her body's spasms. Only the way Jennifer’s whole body grasped around Emily did she signal the crashing waves of pleasure overtaking her. Hot grool seeped from her pussy that coated both her brother's cock in quim and glazed Emily's pussy.
"Oh, oh, oh..." Jennifer sighed, relaxing finally as Nathan slowed and stopped. She tossed her loose and sweat-matted hair aside, panting above Emily. "What are you laughing at?"
"Your face when you cum," Emily giggled at the sight of her normally controlled cousin reduced to such a lurid state. "You just get so into it..." Emily hugged Jennifer tight and smiled, a sweet excuse to rub her body against her cousin from soaking mound to sweaty tits. Jennifer groused.
"Hmph. You're going to have a funny face in just a moment."
"Why?"
"Because my brother hasn't cum yet," Jennifer smirked. As she spoke, the now familiar shaft of Nathan's member lining up with Emily’s hole and thrust in. Like a sword returning to its sheath, his member drove deep into her at the first shove. Their previous mating and Jennifer's quim lubricated her to perfection.
"God, oh god!" Emily mewled, "It's so hot and - and good!" It was her turn to grip tight and endure it. Jennifer brushed the hair from the virgin's face and planted kiss after kiss on her. Emily's rolling eyes refused to shut, and the same went with her mouth. A long string of moans and half-formed words escaped the girl, not a single bit of the sort she could help.
"Yeah, fuck her pussy bro. Mmmm, I can hear it!" Jennifer hummed, and it was true. The distinct smuck and slap of a freshly inseminated pussy taking cock all over again formed the steady baseline of their incestual chorus.
"I can't take it," Emily gasped, "He's so big! I'm going to break!"
"Mmm, break her bro. Break in that virgin - OHH!" Nathan pulled out and slammed his cock into his taunting sister, right down to the hilt. His pace didn't even miss a beat, so now his sharp thrusts slapped against Jennifer’s raised ass. But Emily's respite didn't last long.
"I need you both," Nathan growled, giving his sister's pussy one last hard thrust before switching back to Emily. She howled as his cock, slick with Jennifer's juices, penetrated her barely trained sex all over again.
"Take us," Jennifer gasped, trying without success to catch her breath. "Oh fuck bro, take our fucking pussies!"
"Yes!" Emily muzzled her cry into Jennifer's shoulder as she felt Nathan's cock stretching out her tender sex, "Please fuck us! God!!"
"You dirty girl, saying - FUCK!!" Jennifer took his cock again all the way to her cervix. His heavy palm came down at her tailbone, forcing his sister's gyrating hips to grind against Emily's clit instead. Her well-trimmed mound tickled and amplified her every motion, their exposed clits passing and repassing one another without end.
"I-I'm gonna - MMMM!!" Emily moaned, a new climax swelling while taking Nathan's cock again. Every time he plunged in stretched her virginal pussy anew, molding her sex just for him. Just for his cock. Jennifer's eyes fluttered and Emily's rolled, and they held each other tight.
"He's close," Jennifer warned, "He's going to cum for us!" Nathan couldn't speak any more. Sweat glistened and dripped down his chest and abs, the marathon fucking between both women only picking up speed as his animalistic grunts dominated them both. He stretched Emily with each new entry and spanked Jennifer's wavering ass. He slammed into Jennifer's dripping, pleasure-mad cunt as his balls slapped against Emily’s clit.
"Do it!" Emily wailed as her body tensed along with Jennifer's, "Cum with us, Nathan!"
"Oh fuck bro - AHH! - Fucking cum IN us! Oh fuck I'm - I'M-!"
"CUMMMMING!!!"
Emily screamed. Jennifer shook. Nathan roared. He slammed into his sister's hot, tight body and unleashed a salvo of sticky seed. Two healthy blasts of cum rocketed into his sibling's unprotected pussy before he pulled out and drove into Emily's tightness in turn. For the second time that night the virgin’s womb got a fertile filling. Nathan grunted and howled like a beast, swapping between sister and cousin as both came with him. He stuffed both their gushing pussies with his potent, incestual sperm.
The girls kissed hard, moaning and groaning and quaking uncontrollably. Molten semen poured into their unprotected bodies, only to drool out and mash between their grinding pussies. By the time Nathan's orgasm subsided his cock jerked out its last shots over their messy slits, some great globs of it already mixed between their mashing hips.
The three collapsed where they were. Jennifer draped over Emily as the deflowered girl sighed and kissed her exhausted cousin. Nathan wiped the last drips from his slimy cock onto his sister's thighs and rolled off to the side, drained and spent. Jennifer was the first to speak.
"Damn it, Nathan..." He voice shook along with the rest of her inseminated body. "That was so fucking good..."
"Yeah," Nathan groaned. "I've never cum so hard in my life."
"Emily?" Jennifer nudged her close-eyed cousin, a broad smile touching Emily’s lips. "You still there?"
"Yes..." Emily sighed, "That was... ahhh... I'm so warm now," Emily snuggled against Jennifer as the girl huffed.
"We both are," Jennifer inched her hand back behind them both, feeling the damage that had certainly been done. "Nathan's never cum like that before. Oh god there's so much inside us..."
"Sorry, I couldn't help myself," Nat
han said, wrapping his arms around his claimed and inseminated family. Jennifer and Nathan flanked Emily on either side, their arms forming a willing cage around the satisfied girl. "You girls are just so sexy..."
"Mmmm, it's okay," Emily said, "I'm just glad, so glad. I can't stop smiling."
"Heh, me neither," Jennifer kissed Emily's shoulder. "Next time Nathan won't be so careless with cumming inside us, will he?"
"Yeah," he said, a sheepish sort of smile crossing his face. "Maybe."
"Maybe, huh?" Jennifer pursed her lips and brought her fingers up for them all to see. Nathan's cum stuck to and drooled from them like molasses. "You do this too many times inside us and we'll definitely get in trouble."
"It's okay," Emily sighed, lost in the afterglow and the embrace of her cousins, "I loved it all. I can't wait for next time." Jennifer's eyes lit up, the final spark before inevitable sleep.
"Ohh? She wants more, brother. Tasted the forbidden fruit, and she likes it," Jennifer trailed her fingers up and down Emily’s front. Nathan tugged the light covers up over the three of them.
"She doesn't like it - she loves it!" Nathan chuckled.
"I did, but how could I not?" Emily settled in between her two best friends, her relatives, and now her lovers. "I love you both so much, and even more now."
"Awww, Emily..." Jennifer hugged her, and so did Nathan. "Now you're being all sweet again." She pecked her lips, and Nathan followed suit.
"We still have most of the week left for our vacation," Nathan said. "Lets get some sleep so we get an early start, hmmm?"
"Okay," Emily said, the oblivion of a perfect rest already tugging at the back of her mind. "I love you both."
"Love you too," Nathan and Jennifer said together. And in that loving tangle of arms and spent bodies, they all fell asleep.
Three Months Later
The whole rest of that spring vacation passed with more adventures in the beachside town and even more in the bedroom. Emily learned so much about herself - her body, her sexuality, and her desires. The three of them only had enough time to scratch the surface then, but now after three months away they would finally get together again.
"Crap! I'm going to be late!" Emily hustled from the bus and out into the sunlight. The next four years of college promised to be amazing, especially now that she got formally accepted to the same university that Nathan and Jennifer went to.
She dashed across the street, looking for the meet up point out on the campus lawn. Excitement rushed through her when she saw them standing by the central fountain.
"I'm here!" Emily waved and trotted up. Lately moving quickly was a bit of a strain on her. After the last swim meet wrapped up two months ago she hadn't been exercising as much. Figures that some of that inactivity would show a little around her middle, but none of that mattered as she saw Nathan and Jennifer waiting for her, arm in arm.
"Hey there sporty," Jennifer said, "No packmule getup for you today?"
"Nope! That's all at the house already. It's so beautiful!"
"Oh yeah," Nathan said, "Can't do much better than a small mansion in a college town, eh?"
"Nathan and I have broken in each of those rooms. We know all the best places for, you know," Jennifer gave Emily a little wink. They all knew that every surface had to be re-tested for how well they could facilitate a torrid threesome.
"I've missed you both so much!" Emily threw herself into Nathan's arms first, and the tall boy laughed.
"You too! Jennifer's been all kinds of horny lately, waiting for you."
"That's your fault you know," Jennifer chided.
"What do you mean?" Emily asked.
"Well, Nathan and I got..." Jennifer began, but stopped when Emily came in for her hug. The girl girls paused, and then Jennifer looked down. "Oh my god, you too!?"
"What?" Emily looked down as well. Nothing immediately popped out at her. Her t-shirt had ridden up a little on her belly, unlike the somewhat baggy shirt Jennifer elected to wear. Jennifer held her cousin at arm's length and stared.
"Oh my god, Nathan! Look what you did!" Jennifer exclaimed. Her brother was already staring, motionless. Emily looked between them, confused.
"He did what? I just put on a little weight after swim practice finished up."
"That isn't fat, Emily." Jennifer lifted her shirt some more, and for the first time Emily really looked at herself. The little extra weight was more of a little bulge that angled out just beneath her belly button. Normally her taut stomach was flat as a plain and most still was. A cold realization trickled down her spine. That little hill could only be one thing. Jennifer said it first.
"Emily, you're pregnant."
"I - I am!?" Emily touched her stomach, panic rushing through her. How could this happen!? She only ever had sex once - well, if by once she meant on that one vacation. Sure Nathan didn't really pull out of either of them every single time they did it after that first time, but that shouldn't have been enough to make a baby, right?
"Nathan, you idiot!" Jennifer punched her brother in the shoulder, halting Emily's racing mind. "It's okay. I thought this might happen to you too."
"Me too? What does that...?"
As if in slow motion, Jennifer gave her cousin a knowing smile as she lifted her own shirt. Emily gasped. Her older cousin's stomach, normally smooth and flat just like hers, now had the same exact bump on her belly.
"Looks like he got both of us then," the naughty girl shrugged. “Nathan got me pregnant too!”
"Oh - oh my god! What do we do!?" Emily couldn't believe it, but Jennifer pulled her back to reality.
"Emily, calm down. Our parents are loaded, so we're really set for life no matter what we do."
"R-really?"
"That’s true," Nathan said, the shock on his face turning into a growing smile, "Don't worry Emily. We've got some time to figure out what we'll do. And in the meantime..." He reached out and rubbed his sister's baby bump, "It's going to be amazing."
"Turns out Nathan's a bit of a preggo lover," Jennifer said, "Or maybe it's that I'm so fucking horny right now I could strip down and fuck you both right here!" Their playfulness took the edge off, and like before on vacation Emily felt herself relaxing into a situation she never thought she would.
"You're that horny?"
"Oh yeah," then Jennifer's grin turned absolutely wolfish, "And soon, you will be too."
"That sounds... kind of exciting actually!" Emily said, and it was true. Getting pregnant was not on her list of new things to try, but somehow knowing she was pregnant with the two people who she loved most in the world made all of it better.
Jennifer's eyes lit up and touched Emily's three-month pregnant belly too, sending through her the first warm shocks of naughty pleasure that she would feel for the next six months. That it was incest that made her and Jennifer’s babies, well… that just made the butterflies reawaken in the girl’s fertilized belly.
"What can I say?" Jennifer said, "Welcome to the family, cousin!"
