I yanked it while my cousin was asleep next to me. The next morning he thought I was dreaming of running because the bed was moving.
That is kind of disgusting, how did you react to their story?
I thought it was funny. I hoped that nobody would find out but then he started acting all freaky about it.
You shouldn't masterbate with someone sleeping next to you especially your cousin. It is weird and creepy.
I'm thinking of yanking next time I think he's sleeping.
Find another room or private spot if you feel the urge to pleasure yourself. They'll catch on soon enough and not want to hang out with you if you keep this perverted behavior up.
