Most nights mom and mom who fuck very loudly till the morning and my mind was racing about how it would be better for them to have a real cock instead... of a plastic one , on one faithfully night when my adopted parent were having sex my step sister came into my room saying she was scared by a movie she had watched earlier and that she wanted to stay with me , this was like a dream come true because i had my eye on her fr sometime.Has she was about to get into my bed she stopped and confessed. Then she was gone in a flash and until we were in the back seat of dads car driving home, she never said a word to me. I kept looking at my parents in front to see if they were watching, and any chance I got, I took her hand and put it in my lap. As soon as her hand touched my cock, it twitched and she smiled and chuckled. Mom asked her what was so funny, and my boner disappeared in a hurry. She only said to mom that I was being silly and that’s why she laughed.The next time I was alone with. I felt his hands against my upper back as he began to thrust his manhood down my throat. I did my best not to gag but his penis was by no means small. At this point I thought this might be all he wants, a good blow job. This thought was soon dispelled as he brought out a couple of condoms from his pocket and said "let's move to the bedroom" as he pulled me to my feet.As we entered my bedroom I began to attempt to pull off the little black dress to get a little more flexible shall we say. He. ..As I contemplated, Hank's butt began to push back against me and slowly grind against my cock. I guess we were both thinking that we'd like to go again then! I pushed gently against his grinding motion and he moaned softly as his eyes opened and he turned to kiss me.I could still taste the cum on his lips from last night. It obviously didn't gross him out to taste his own cum and I found that to be terribly erotic. I started to think about what a turn on it would be to feed him his cum while.
