Offline/Force Nicole to stop
"Hey," you whisper to Nicole. She doesn't even flinch. "Hey." Again nothing. You regrettably push her away from you and pry her hand off your cock. "We can't do this."
She looks startled, insulted even. "Why?"
You shift an eyebrow and glance to the fire. "People can see us."
Nicole opens her mouth to speak but nothing comes out. She then turns away from you. She seems really angry.
"Hey, I'm sor-"
Nicole stands up and runs away, flashing her ass while heading out of camp in the direction of your cabin. In her hurry to leave she nearly rips the blanket away from you. It's only a bit of luck and twitchy reflexes that let you snatch the blanket from the air to regain control of it and keep your mostly naked state hidden. By the time you're certain that you weren't exposed she's already out of sight.
You have to stealthily pull your swim trunks back on before you can even think about getting up to follow her. Even then you take your time, shrugging at Mike, scratching your head, anything to make it seem less like you're running after her than you desperately want to. After you do manage to stand, you casually walk off in no particular direction. Only once you're confident that the darkness has shrouded you do you bolt for the path to your cabin.
When you burst in a minute later Nicole is standing there crying behind her glasses, a propped flashlight in the corner the only source of light. You close the door and are about to apologize when she steps up and slaps her hands against your bared chest.
"I don't care if they find out! I want everyone to know! I shouldn't have to hide that I like you! That I lo-"
You kiss your fiery cousin mid sentence. The adrenaline, endorphins, and lust that has been building in you is making it hard to want anything else, and now that you're alone witnessing her overflowing passion that becomes your entire focus. You gasp for breath between kisses, having ran the whole way here. She takes those tiny breaks to try to continue professing her love to you, but soon enough she realizes that you're clearly both on the same page.
The two of you strip hastily, an unspoken understanding that this is really going somewhere, and you pull Nicole down onto your sleeping bag. She lays on top of you and the two of you continue to make out for some time, your cock poking up between her legs. Eventually she sits up and gives you a warm, flirtatious smile. Reaching under herself and repositioning your erection, you get to see her wiggle your head into her slit and then watch as her bare lips wane and stretch apart as she sinks down onto you, slowly taking you inch by inch.
"Mmph. It's so big," she notes with a squirm.
She doesn't get all the way down before she stops, either bottoming out or finding her limit. She looks around awkwardly, her cheeks flush, avoiding your eyes. Now that she's got you inside her she seems less sure of herself. But after some encouragement and experimenting she starts gyrating on top of you. She looks more like she's trying to hump a pillow than take a cock, but at least she's trying. Although when you try to guide her it isn't much better. Whatever you try, everything is all jerky and awkward, but to be fair it is your first time as well as hers.
You take off her glasses and set them aside, trying to be helpful while she finds a rhythm that works for her. Eventually she leans forward, plants her hands on either side of your head, and starts bouncing her scant hips up and down, riding your shaft like a carnival game; intense focus but mostly having fun.
She struggles a bit here and there, faltering and startling herself every time she drops farther down than she intended. But frustration and enthusiasm soon take over and she starts bucking on top of you with frantic energy, fucking like a bunny rabbit.
Watching her thrash around on top of you is amazing. Did she not realize she wanted this before now? Or maybe it was just fear and uncertainty. Or she didn't want to take it this far knowing you might not see each other for a long time. It hardly matters now and it's but a fleeting thought. You're too wrapped up by how amazing this is, seeing you cousin's little titties bounce around, her hair a cascading torrent of flailing locks skimming across your skin. She looks desperate to cum, but she has no idea that there's no way she can beat you.
With your thoughts so focused on your cousin you hardly even notice your orgasm creeping up on you. With a hearty grunt and a shout of "I'm cumming!" you grab onto Nicole's hips and wildly buck up into her. She yelps and tries to temper your thrusts but you're totally concerned with your own release and plow into her full bore. As you spew your seed deep inside her she drops one of her shoulders onto your chest, curling her body inward. Thrust after thrust you fire your cum, only slowing your movements as your balls empty, your entire body feeling spent by the crazy eruption that just hit you.
"D-d-don't... stop..."
Your cousin's weak cry spurs you on. You're out of gas, as well as cum, but grit your teeth and keep thrusting anyway. You realize her hand is beneath her furiously attacking her clit. Half a minute later, your legs shaking from the intensity of your bucking and willing yourself to stay hard, Nicole whimpers and breaks, whispering "yesyesyesyes..." while you fuck through her orgasm. A minute later she crashes on top of you, your semi-hard penis still enveloped by the warmth of her vagina. Heavy breathing is now the only sound filling the room, both of you taking time to get your wits about you and process what just happened.
"You cummed inside me," she says, the answer to a question no one asked.
"Yeah."
You both lay still, unsure of what to do. You never talked about this, about whether she was okay with that, whether she was on the pill or even whether she's had a period. But now that you've gone and done it there seems little point in discussing it in length. You just rub Nicole's back and stroke her hair while she thinks in silence.
A few minutes later she slides herself down the shaft of your semi until her vulva presses against your balls. You're still recovering so you're far from full mast, but you're stiff enough for her to still ride you. And she does, rotating her pelvis just like the pillow-fuck she tried before. She plays around for a while, experimenting and feeling things. But when she sits up again, so do you. The two of you make out in each other's arms while she rides your lap and readies your cock for another round.
It's amazing that you've stayed inside her this whole time. You'd like to try other positions but you also love that you're still connected in the most intimate way possible and don't want to disrupt that, if only out of some irrational fear that Nicole won't let you back in. Stubbornly, you hug your cousin tight and almost carry her down onto her back, falling the last few inches. You're on top now and still well buried, so you start thrusting as soon as you hit the floor, focusing on speed rather than technique.
You bounce against your cousin over and over, slowly pushing her a millimeter at a time across the surface of your sleeping bag. Nicole raises her arms over her head to touch the wall and keep you from fucking her into it. You'd like to get her off again and try to play with her nipples a little but you really just want to pump a furious second load of jizz inside her straining pussy, so your focus is pretty narrow. Despite that, Nicole lets out a low slow moan as you plow forward with your own version of bunny-fucking.
"Uuuuugggghh... Uh-huuuuuh. Huh. Huh. Ooooooo... I... I'm...!"
She squeals and squirms while you fuck her to her second orgasm. Well, the second tonight. What is it, the 5th today? 6th? You don't even know. But you know you love the look on her face right now, mouth open, nose wrinkled, senses exploding with pleasure.
She presses her hand against your stomach to get you to slow down for a while. She may have wanted you to stop, but you stubbornly refuse to. Instead you slowly push your shaft all the way in until you bottom out and then pull all the way back until you see the ridge of your head poking free, rinse, repeat. You stretch her insides, steady pressure helping to make you fit. The slow tormenting stimulation is frankly torture for both of you but in the best way. After her orgasm passes, this new turtle-fuck seems to drive Nicole crazy. Every now and then she spasms without warning, squeaks out a gasp, an aftershock of intense pleasure.
After a few minutes of this she pulls you down onto her so she can kiss you. This plants you deep inside her and she wraps one leg around your lower back to help keep you there. This sure seems like an invitation and you slowly ramp up your movements but her leg keeps you locked close to her. She wants to kiss more than fuck but you're still seeking that release. She grabs onto your face and starts experimenting with her tongue. What you had envisaged as a fast frenetic fuckfest quickly turns into a passionate round of love-making. And as you steadily grind against her pussy, her tongue in your mouth, her legs wrapped around you, bliss flows through you. A minute later it flows into Nicole as well, in more ways than one, both of you finding another orgasm together.
You collapse on top of your cousin while her pussy squeezes your shaft in short little pulses of pleasure. You've been inside her for so long now you never want to pull out. Maybe you can just stay joined forever, fucking 'til the world ends.
You wake up the next morning with Nicole cuddled up next to you, both of you still naked but with Nicole's unzipped sleeping bag draped on top of you. Clearly she didn't fall asleep before you did, but she's deep asleep right now. Last night is all a little hazy. You're not sure how many times you two came in the end, but you don't even care to think about it right now. This moment is too perfect, having Nicole's warm naked body pressed against your own, her chest slowly rising and falling, her hair wild and disheveled - she's like a purring, sleepy little sex kitten. You watch her for a long time, her peaceful slumber next to you so comforting and safe.
Eventually you decide to kiss her awake, and she returns your loving lips through her own equally sleepy haze. You skirt your hands across her chest to tease her tits, hoping to restart what you ended last night, but as Nicole gets her wits about her she thinks much more rationally.
"What time is it? They said we're leaving early, right? We should pack up before someone comes. Or what if they decide to leave without us?"
