So i have been seeing Paula for a while now and masturbating a few times a week for her. One night as I'm laying on her bed playing with my dick for her she tells me that she has told her sister about what she has me doing. She tells me this right as I start to cum it was so exciting to me, she smiles at me and tells me to use my cum as lube and to make myself cum again. As I stroke my cock she tells me all about her and her sisters conversation about me masturbating for her all the time. She says her sister wants to watch also and how she thinks that would be a great idea. I cum pretty hard with all that talk and Paula is happy. About a week later I come over and Paula tells me to get undressed after I do and lay down on the bed my dick hard already, she opens her closet door and her sister walks out in to the room and stares at my dick. She sits down with her sister and Paula tells me to go a head and start rubbing it. As I lay there playing with my cock her sister asks me if I really do enjoy playing with my dick for her and her sister to which I answer by cumming all over myself. Paula told her to “watch this” and proceeded to tell me to do it again. Her sister watched in awe as I scooped up my cum and rubbed it up and down my cock. She loved how my cum looked on my cock. The rest of the time I was playing with it they were talking to each other and watching my hand go up and down till I cam again. It was so hot masturbating to two women at the same time, god I was so horny. Then I find out their mother knows, but nothing ever happenedexcept i think i can catchfunny looks from her out of the corner of me eye.
