Get ready for bed

At this point, it's close enough to your typical bedtime to start getting ready to go to sleep, even though it might be a little on the early side for a weekend, and you suggest the same order of using the room to get changed, you going first then she can take her time after. Lexi agrees and stays in the living room while you head to your room where you quickly change into what you normally sleep in, a pair of loose athletic shorts. You think for a second that it might be more appropriate to also put on a T-shirt if you're going to be sharing the room with your cousin, but you dismiss that idea, hoping instead that Lexi might like what she sees and check you out a little, just like you've been doing to her all day.

Decision made, you start leaving the room, but it dawns on you that you haven't set up the air mattress yet and mention the same to Lexi when you walk out to let her know she can use the room now, but letting her know you'll have to take care of it after she's done in there.

"Damn David, I didn't realize you were in such great shape! Those shirts you were wearing today weren't doing anything to show off your body." she compliments you, staring at your naked torso for a bit before addressing what you actually told her in the first place. "You know what, why don't you just forget about the air mattress? We can just sleep in your bed together. Your bed is big enough for us to both be in it and not even touch each other. Besides, we're family anyway. If you can't share a bed with family, who can you share one with?" she reasons with you.

You really didn't want to go through the trouble of setting up the air mattress or sleep on it for that matter so you agree, and she leaves to get changed herself. You grin a little at the thought of her complimenting you, thinking to yourself that you accomplished what you wanted, then pause, wondering if you'll even be able to get to sleep with the cousin you'd been having dirty thoughts about lying next to you in bed all night long. You don't have a chance to think about that for long because another moment later, she peaks her head out from your door.

"Hey David, do you think I could borrow one of your T-shirts?" she calls down the hall to you. "I forgot to bring something to sleep in."

You tell her that's fine and instruct her where she can find one for herself then head to the bathroom to brush your teeth. After you've finished, you knock on the door and tell Lexi the bathroom is free for her whenever she's ready then head to the kitchen to have a glass of water. You've gulped down half the glass when you hear your door open, then the bathroom door close, indicating that Lexi is finished getting changed, so you make your way back to your room and cimb into bed onto your usual side.

When Lexi comes back in, you've gotten yourself comfortable and pulled the sheets up over you, and it's a good thing you did, because, holy fuck, does she look sexy. You can feel blood rushing to your dick at the site of your little cousin and you hope the sheets will help conceal your growing erection because you realize those athletic shorts you're wearing will do nothing to contain it at this point.

She's picked one of your older, white T-shirts that's made out of thinner material as it is, but has gotten worn and abused enough where a few, small holes have started to form around the collar and some portions look like they could be see-through. The length drops to mid thigh on her, so her lower half isn't exposed to your eyes, but the material is doing nothing to hide her two, pert nipples that are currently poking out and you think you can the darker outline of her areola. "I hope it's ok that I borrowed this one?" she asks when she sees you staring at her.

"Uh, yeah, that's fine, but you could have picked one that wasn't so worn out too." you tell her, while thinking that she actually couldn't have picked a more perfect shirt to wear. Of course, now you're even more concerned about your ability to get any sleep tonight whatsoever.

Lexi gives you a shrug and a smile, telling you she loves it and that it's "super comfortable" then turns off the light with the switch on the wall and climbs into bed with you.

Rolling to your side so that your back is to her, and your dick is pointed away, you try to get comfortable and think about anything other than her body and the things you'd like to do to it, but before you even have a chance to adjust your pillow how you like it, she speaks up.

"Hey David, can I talk to you about something?" she asks, then continues when you answer with a "Sure" and roll onto your back to acknowledge her.

"Ok. So I told you how I've never really had a serious boyfriend already, but because of that, I don't really have much experience with guys either. See, I never wanted to just hook up with someone in school. It's so small, everyone knows everyone else's business, and I didn't feel like dealing with that. Now that I'm going to be in college, I want to try things but I'm nervous."

"Wait, what?" you ask, caught off guard by this unexpected bit of information.

You feel Lexi changing her position next to you and your eyes have adjusted to the dark enough by this point that you can see she's now on her side facing you. "It's not like I think I won't be able to find plenty of guys that will want to screw around, but I haven't even seen a penis in real life before David! What if I freak out the first time I see one? What if I mess up when we're fooling around? What if I squeeze it too hard, or not hard enough? How will I know if I'm doing it right? Then my friends have warned me about using too much teeth... and don't even get me started on actually having sex!" she tells you, rambling on, letting all her concerns spill free from her mouth.

You didn't think Lexi was that drunk, but maybe she hid it well, because this wasn't anything you were expecting at all. First of all, you weren't planning on hearing about your little cousin's sexual experience, or more accurately, lack of experience. Secondly, and related to the first point, you're pretty surprised to find out that Lexi is still a virgin. Not only is she a virgin, but she says she hasn't even seen a dick before? No way would you have guessed that after watching her finger herself earlier today. Thirdly, it seems like she might be ready to ask for your advise on these things, which is a weird boundary that you're not sure you have the skills or desire to try and navigate around tactfully.

Your thoughts are interrupted once again by Lexi's voice, much quieter and with obvious apprehension in it this time. "My friends have told me plenty David, I've read up on things, watched some porn, and I've even practiced with cucumbers, but I know it's not the same thing. M... Maybe you could let me see yours?" she asks you even more nervously.

Wow! OK, if you weren't expecting those other things, you sure as hell weren't expecting this! Your barely legal cousin, the one with the mom who you've fantasized about for years. The one who you've been checking out all day long, watched masturbate on this exact bed your now lying in, and spanked one out to right after, is asking to see your dick?!? This has suddenly gotten to the point where all those fantasies could become reality, but are you actually willing to cross that line?
