I had been dating my boyfriend for a while now, and like any virgin girl, I was worried that his penis would be too big for my vagina, and I couldn’t stand the pain. I talked about it with my mother, she was a divorced woman and I knew she had been with more men than just my father. She explained that I was sure my pussy would dilate enough for my girlfriend’s cock to fit, I didn’t have to worry. But I wasn’t having it all my way, so she invited me and my boyfriend into bed with her. There she asked us to masturbate her pussy and ass, so that we could see how my holes were able to open up. At first I died of embarrassment, but watching my mother cum was a lesson we will never forget.
