I can't sleep a wink

Well this sucks. Now I'm hot and bothered and just really fucking hot. I had to get out of this position and these stupid clothes. I was sweating by this point. Alice's breathing finally seemed to slow down, when she gently rolled out of my chest. I took the chance to retract my arm from under her gently. She stirred a bit but seemed to settle down.

Alice was a real marvel. I never knew how she managed to fall asleep so quickly and so deeply. She always had this ability.

But regardless, I was burning up. After a bit of a struggle I managed to undo the buttons of my shirt and and slip off my pajama pants. "Ah," I said aloud. I felt my internal temperature drop to safe measures again. My breasts were free to the night air, and my legs could breathe. I decided against removing my entire shirt, just the unbuttoning should be enough.

I ran my hands over my chest to get them into a more comfortable place, only to find that my nipples were still rock hard. Both my arms were now free. There was a single soft piece of fabric between my legs. My sister should be fast asleep by now. There was opportunity here.

But could I really just jill off with my sister right here? Should I try to resist the urges?
