Just lay there

You are shocked an intruiged by the thought of there being another in your sister's bed. Who could it be you think to yourself. Could it be Amy her roomate? You could have swore you saw her silhoutte over there in her own bed when you entered the room. Maybe it's one of the girls you played truth or dare with earlier? You can't sleep, no matter how hard you try to just let it pass and hope for the morning. You're wore out, and you tell yourself that this can wait until the morning.

Do you wait until daylight? Do you get a little curious and feel up the other member in the bed? Or do you encourage the hand of the stranger towards your curious and rock hard cock?
