You want her to stop

At this point you're back awake. "Listen, I thought I told you no touching, we had a deal that you would let me get some sleep. I've had a long day."

"Sorry, I don't know what came over me," she said.

With that you turn over and fall off into a deep sleep.

Amanda though... she is restless. After hearing you snoring deeply she gives you a push to try to quiet you down. You don't budge or seem to notice. So, she grabs and squeezes your butt. Again, no movement.

Hmm... her curiosity can't resist and the nerdy girl goes straight for it this time. She pulls your boxers down in one fell swoop and steps back, waiting for movement. Nothing.

She admires the goods and then starts playing with your limp dick, pushing it from side to side, all the vigilant watching for you to stir. Nothing. You're out deep.

She even thumps and flicks it a few times, it starts to harden and she gets excited. You roll onto your back and she freezes. Scared that she's disturbed you, she waits a second and you go right back to snoring, but your hard dick is flagpoling straight up now. She climbs on top of you, with her legs spread to the sides, and rubbing her hand up and down the shaft slowly.

She hears you stir a bit, but doesn't care at this point. She picks up the pace. You start to squint your eyes in confusion. She's really getting it now. Her stroking is not stopping. Then, you let out a moan and wake as cum erupts from your dick and your body spasms, your mind not caught up to what's happening. Amanda is grinning from ear to ear.
