After our date on Friday, Trudy and I ended up at her dorm and began making out. When it came time that we were going to have sex, Trudy told me she h...d a surprise for me. She had started taking the pill again the day before and so I wouldn't need a condom. This time making love with her was unbelievable. Just the feel of no condom made a world of difference. I must have come in her three times that night.We had oral sex but I did that before I put my cock in her. Her pussy was so inviting, all. I wanted to help my brother, and I couldn’t do that if I was feeling tense.An idea suddenly popped into my head, and I couldn’t shake it: I should masturbate. I should masturbate in front of my brother. I should masturbate while my brother jerks off in front of him. I should masturbate while watching my brother. I should get myself off while watching my brother’s cock.I tried to dismiss the thought - of course I couldn’t masturbate in front of my brother ... but the more I thought about it, the. "She set the nail polish on the table by the bed and picked up the hair brush. Pam scooted on the bed, turned her back to Debbie and sat with her legs crossed, her hands resting on her knees and her fingers spread wide. Debbie was quiet while she brushed. Pam was afraid she said something to make her angry. She tried to think of something else to talk about, and remembered what the girls in math class said."I heard Mr. Smith has a big dick," she said, and wondered why she brought that up.Debbie. The next thing I knew I was sitting on the ground with my back against the wall next to her door, rubbing my soaking pussy to the sounds of my brother absolutely fucking our mother. I continued this for quite some time. Rubbing, fingering, orgasming over and over. I looked at my phone and discovered that this had been going on for two whole hours. Just how long were they going to go at it?Regardless… I went back to the task at hand. If they were still going then so was I. I continued to finger.
