Sweet, wonderful torture. All my students watching me, seeing me struggle not to cum in front of them. But I wanted to. I wanted to explode. To cum li...ke a slut before my students like the nasty, filthy whore I was. I wanted to rip down my panties, spread my thighs, and let them see the vibrator humming away inside me.To scream out: “My nephew is my Master and I am his nasty sex slave!”I bit my lip instead.“Looks so difficult,” Melody said. “Be brave, Mom, you can get through it.”“T-thanks,. It was a cold November Friday evening when I got home from work at about 7pm which is kinda late for me. About 45 minutes later knock came on door to which I found it was Lisa our boys babysitter and my best friends 19 year old daughter she is a light skin African American teen and I was best friends with her dad and mom since high school. She said hello Mr.mark I bet you didn't know I had the boys did you actually no I figured the wife was out shopping. Yea well I probably shouldn't say. " Aunt Becky laughed, saying " My, my, we are getting rather advanced in our early sex life. You are on!" She jumped out of bed, her tits, jiggling, her ass shaking and walked briskly to the bathroom. My hard cock pointing the way, as I joined her in the bathroom. She stood behind me, her hand on my butt. She pushed me towards the toilet. She had already lifted the seat, standing behind me. Her face peeking around my right side, her hand taking hold of my cock. She said in a teasing voice. The hotel was nice mostly families ,after several days of sun bathing and meals out I was ready for something a little more adventurous wendy had arrange for the hotels baby sitting staff to look after her son,so that night we were going to hit the bars. but unfortunately her little boy started playing up so we decided to stay at the hotel. I was really pissed off coz id gone to a lot of effort to look good in my sexy little black strapless dress . wendy and her spoilt little brat went back to.
