This happened about 4 months ago. I have lived with my mom and step dad for as long as I can remember. He is like a dad to me.
Since I started to get puberty, my mom told me about masterbation. My step dad sometimes jokes around about it. They have made it clear that it is ok in private.
I masterbate just about every night in my bed. I learned to use my hand and rub my clit up and down. It feels sooo good.
Usually when I go to bed I say goodnight to my parents then take a shower then go to bed. But this one night I was a few houses down babysitting. I got home at 10 and my parents were already in bed. I took a shower and when I was done I saw that there TV was on. I went to say goodnight but there door was shut all but a crack. I decided to peek in to see if they were asleep.
To my suprise and excitement, there was my step dad laying next to my sleeping mom with his hard dick in his hand slowly stroking it up and down. I just froze there I couldnt believe what I was seeing. Ive never seen a real dick before. It was big and straight. He has a tissue on his belly. After a while he started stroking faster and faster. Suddenly his white sperm shot out of the tip onto the tissue. It was such a turn on. I got horny as hell. He started to get up so I ran back to my room. I went to bed and masterbated until I had a big orgasm. I have tried to catch him again but havent.
About a month after that I was in my bed watching tv and rubbing myself with the sheet over me and my hand down my pj bottoms. I was really getting into it and about to orgasm when all of a sudden my step dad walks in. I just froze with my hand still in my underware. I wasnt sure if he saw what I was doing or not. He said he wanted to make sure my window was closed because the airconditioning was on. He just walked up to me, leaned down and gave me a kiss on my cheek and said goodnight. But at the same time he placed his hand right on top of mine that was still right on my clit. He gave my hand a little squeeze. He just smiled and said sweet dreams. When he got to the door he turned and smiled again and said how about if I shut your door for you. I was sooo embarrassed I just shyly said ok. After he left, it took a while but I finished rubbing my clit and had a huge orgasm.
The next day it was like nothing happened. I still try to catch him masterbating but no luck so far.
I am horny again!
