Offline/Try not to sate Nicole's curiosity
"Oh, umm... well they eventually got naked. Hannah got on top of him and teased him a bunch with her boobs. Then they..." You've already given her so many details. And because of that it feels even more awkward than before to give a play by play to your younger cousin about your older cousin's drunken sexual exploits. What is her deal anyway? Is she trying to test your honesty? You'd much rather she just wait and see them go at it tonight. "Well, then they did it. Lots. And lots and lots."
Nicole purses her lips in a brief scowl then slumps her shoulders. She's definitely disappointed but you figure it's for the best. But you only manage to steer the conversation elsewhere for a short while, maybe 20 minutes, before she asks again.
"Can you tell me more about what Jet and Hannah did?"
"Didn't I tell you already? They did it. Lots."
"Yeah, but how? How did Jet..." She makes a weird twisty-wavey motion with her hand, like she's not even sure what to mime. You just roll your eyes.
"Y'know. With his thing."
"You don't have to be so weird about it," huffs Nicole with another scowl, crossing her arms.
"I think you're the one being weird."
"I'm not! I'm just curious! You're the one who said "it's just sex". So it shouldn't be such a big deal. But you're making it into one! I just want to talk about it. My mom thinks I don't even care about boys or anything, but what does she know? I'm not a kid anymore. I have feelings." She takes a short pause from her rant to calm down. "I didn't mean to be weird. I just thought, since we talked before, that we still could. But if you don't want to talk... maybe you could, like, show me or something. You're bad at explaining anyway."
You raise your other eyebrow. "You want me to show you what they did?"
Nicole instantly gets a funny look on her face, as if she didn't just suggest that. "I mean you can. If it's easier."
You're not sure what's going through her head, but you know what's going through yours. You were trying to keep her curious but it's hard to pass up an offer like this. You think about very briefly, shrug, then lie down. She watches you curiously, waiting for you to do something else, but you're waiting for her.
"C'mon," you insist, gesturing. "Do you want me to show you or not?"
"Me?" she replies, pointing at herself. Nicole bites her lip then hesitantly gets up onto her knees. She shuffles forward and gingerly straddles you before sitting down on your stomach, planting her hands atop her bare thighs at the edge of her jean shorts. Having your cousin get on top of you makes you both instantly skittish.
"Okay. Good enough. But... Hannah was leaning back. She had her hands on Jet's legs."
Nicole nods, then realizes a second later that those were instructions. She looks behind her and finds a safe place for her hands then shifts her shoulders back, pushing out her chest in the process. "Like this?"
That inviting shift convinces you to 'show' Nicole what also happened. As cool as you can, you reach up and palm Nicole's meager bumps through her blue sleeveless t-shirt. There are enough layers at play that it's not a very satisfying grab, but it's still fun to roleplay as Jet for a moment, giving an eager but soft squeeze of your "not a kid" cousin's mostly flat chest.
"Hey! Jay!" Nicole rights herself and puts her hands over yours. You're expecting her to rip your hands away and scold you or stomp off, and you're just as prepared to play it off as a joke, but she continues to sit there waiting, her hands atop yours on her chest, staring down at you. She looks so cute in her glasses and choker. Granted, she looks real mad too, but she's waiting, expecting you to say something for yourself.
"...this is nothing. Hannah was topless."
"Jay!" she protests again. You relent and pull your hands away. She's outright scowling at you now, her face starting to redden. She even crosses her arms. Once again you expect her to end this. But after another moment she asks, "Then what happened?"
"Umm... they kinda hugged, I guess. Laying down though."
Nicole looks away from you, thinking. She then drops down on top of you, laying her body against yours, shifting down slightly so she can nestle her head against your chest. Her legs are still straddling you but are now just below your hips while her arms creep their way to your sides. You wrap your arms around her in kind and the two of you lay still. It's plenty awkward, but also nice; comforting but intimate in a forced kinda way.
"Is this all they did?" asks Nicole with a hint of either frustration or impatience as the silence stretches on.
"No. They kissed a lot too. We can skip that. But Jet did more stuff with her boobs..." Nicole briefly looks up at you over her glasses and gives you a more playful scowl than before. "Yeah we'll skip that too. And then Jet just kinda... did this..."
Planting your feet firmly, you raise and lower your hips underneath your cousin. She's laying right on top of you so you mostly lift her slightly into the air, but as you find your rhythm you end up sliding her higher and manage to grind against her pelvis a little, which is made easier as her legs shift further out thanks to her wide straddle.
The two of you go silent again as you slowly dry hump your cousin in your cabin. It's so deliciously wrong and you're getting plenty hard, but you're worried it's one step too far for her... until she starts grinding back. That validation, her silent consent, spurs you on. The two of you hornily hump one another for minutes on end, neither of you trying to seem too into it but both of you adjusting to hit new angles periodically. You're actually getting kinda sweaty by the time the sounds of your breathing are interrupted by Nicole.
"Wh- what else?"
"Uh... this."
You roll to the side, taking Nicole with you. Once you've planted her on her back, you pull away to witness the surprised expression on her face. Her legs are already pointed up in the air, Nicole still straddling you from her back, but you reach down to grab behind her knees and push them back a little higher and a touch wider.
When you press yourself down between her legs and twist your hips Nicole brings her hands up to her mouth. With some amount of showmanship, you curl your back and roll your pelvis, grinding Nicole with the bulge in your pants using more exaggerated movements than Jet ever did to Hannah. The relatively innocent dry humping you participated in a moment ago is far removed from the outright gratuitous act you're now performing on your cousin.
More minutes tick by as you both watch your crotches rub together. You keep thinking that Nicole is going to stop this at any moment but she's just flexing her pelvis against yours, letting it all go further and further. She tucks her hands under her chin and looks on with concerned interest, her cheeks getting rosier by the minute.
Pushing for accuracy, you pull away from Nicole a few times so you can hit your crotch against hers, mimicking Jet's powerful lengthy thrusts. Your own cock being trapped in your pants makes this less enjoyable than the constant contact of grinding. It is a little fun to smack your hips against her butt and poke at her underside with your bulge, but you're pretty sure you both prefer it when you're repeatedly sweeping your constrained stiffy across her covered mound, pressing yourself up and down her sex.
"And he... and what else did they... do?" Nicole asks, her breath a tad shaky.
"This. A lot." Another moment passes with you happily grinding away. "I guess we're basically having sex with our clothes on, huh."
"No. We aren-" She's quick to shut you down but nearly as quick to stop herself. Thinking it over, she tries to lighten up and admit to herself what's going on. "Maybe. Yeah. I guess so. This... is kinda weird," she states with a worried smile.
You can't help but chuckle nervously. "Yeah! Just imagine laying beside this for hours and hours. Although I guess there was one other thing that Jet did..."
