Offline/Let Nicole finish herself off
You remain still, willing to let her have her fun. The most difficult part of that is staying 'unconscious'. It's hard to keep your breathing under control and your cock throbs with pleasure every now and then, but nothing that she cares to notice. It does occur to you that if she actually thinks you're asleep then this is a little bit rapey, but it's innocent enough. Besides, you'd let her do a lot more to you.
Nicole starts to twist beside you, her legs far more active than they should be for a girl trying to secretly masturbate. But only seconds into her weird spasm she unexpectedly stops, and not just twisting. Her grip leaves your cock and she lifts her head from the pillow. You close your eyes, not wanting to get caught awake. A few seconds later you sense her hand waving in front of your face, air moving around and the dim morning light flickering over your eyelids. You can then feel her sit up and shift her feet. Cautiously peeking past your eyelashes, you watch as Nicole pushes her panties down her legs, the flap of the sleeping bag pushed aside. She gets her panties to her ankles but stops short of taking them all the way off. Maybe it's not quite reckless, but she sure isn't playing it safe. When this girl gets into something she sure plays risky. Yesterday alone was proof of that.
She lays back pulling the sleeping bag closed and you shut your eyes again. Gingerly she slips her arm up over your side and picks up your cock once more. When she turns into you, one of her knees slips over your leg. You can feel the stretched panties between her ankles stretched across your shin. Cozying up to you again she picks up where she left off, first breathing into your neck and then hiding her face in the pillow as before.
The back of her hand frequently taps against your hip as she diddles herself. She's basically straddling your side, trying to wrap her body around you. You can only dream of what's going through her mind right now. Maybe she's imagining riding your cock, both her little tits bouncing freely. Maybe a team of guys are taking her from every angle. Or maybe she's just thinking about kissing you.
Her legs are much less active now, only shifting on occasion. Her whimpers restart quickly. The hand between her legs is moving furiously. The one on your cock just sits there, but her thumb and finger gently play with the ridge of your head, tracing the edge and twisting it softly.
A sharp gasp is followed by silence. Her hand never stops shaking between her legs. Her other hand reflexively squeezes your shaft tight. A few seconds later a long strained moan gets muffled by the pillow. Her leg shudders between yours as she brings herself to climax pressed against you. Heavy breathing follows and she tries to compose herself. She doesn't wait long before she sits up, pulling her panties back into place, then slips back underneath the covers with you.
Between your cum-filled boxers nearby and her fresh intoxicating girl spunk there's a thick scent of sex filling the air. You desperately hope no one comes to your cabin today.
Nicole finds her position again, nestled against your side. Curiously, her hand goes right back to your stiff member without a hint of hesitation. You try to explain that away for her. Maybe that's how she first woke up and is trying to keep everything consistent to not disturb you. Or she's just fully exploiting her sleeping cousin. When her fingers are quick to trace around your ridge again it makes you think it's more the latter than anything.
You wait a while, expecting her to stop fingering your cock at some point, but that doesn't happen. Quite the opposite. She's still hungry. She slips her free hand back into her panties to do even more fingering. Mere seconds later she gasps, releasing a raspy exhale that is hardly controlled. Her face slowly turns to the pillow again and soon enough she's right back where she started, masturbating eagerly and not-so-quietly while fondling your junk and manipulating your glans.
You've heard about girls having multiple orgasms, but it's weird to experience it. When you cum you're usually not ready again for a while. But Nicole hardly took any time to restart, and she's already sounding close again. You're not sure if you're jealous or intimidated. How many more times will she cum? How many has she already? Surely you can't stay undetected all morning with her jilling off next to you. You may as well interrupt her.
