My sister and I used to masturbate together-sometimes we would lay in our beds and masturbate before we went to bed at night (it sure helped us to sleep) and I would watch her rub her clit back and forth, and when she came she would roll back and forth on the bed with the fingers of one hand on her clit and the fingers of the other hand in her mouth to keep from screaming. Sometimes we would do kind of a "quickie"- we would both go into the bathroom together and lock the door, and pull our pants down around our knees and rub our clits fast and hard-we couldn't spend too much time or our parents would get suspicious-I could see real clearly the stages of her excitement-her nipples would get rock hard and poke out through her shirt, her face would turn red, then she would stand on her tiptoes and put her legs tight together and moan as she came-sometimes we came at exactly the same time. The first guy that I ever saw masturbate was my step-brother;I came home one day and the door to the bathroom was ajar and I could see him rubbing the skin back and forth like mad over his dick-then the head turned purple and he moaned as these long streams of come hit the floor-I sure thought about that a lot when I rubbed my clit as I laid in bed. I love for the man I'm with now to pull on his dick while he straddles my belly, and to watch the come streams flow onto my tummy and into my belly button while he moans in rhythm-that's it, baby.
