Looking into his eyes I sternly say "You ARE going to behave aren't you my slave" then I slapped his face hard leaving his cheek pink.His eyes widened...and he replied "Yes my Mistress I am here to serve you."I had established my dominance now it was time for the games to begin."I can see the bulge in your jeans growing I think my slave is getting excited" I said as I put on some music and walked over to the couch and had a seat."Stephen come over here NOW you little slut and do a strip tease for. If I was walking home I had to be home before dark but if Cindi’s mother was going to drive me home then I could stay out until ten o’clock. Cindi’s mother said that she would drive me home so that I could stay longer. Since it was Sunday and a school night I also had to promise her that my homework was done and that I would get up in the morning without giving her any trouble. I promised.Then Cindi’s mother called Cindi downstairs and had her sit next to me on the couch, then she sat across. Now I started driving into her and withdrawing in a steady pace. Not fast, not slow, just a nice rhythm. As snug as Marty was, our mingled juices kept us well lubricated. Her pussy walls milking the life from me. I didn't want this to end, but at the same time I wasn't in control. Marty seemed to relish the feel of my cock deep within her. Our eyes locked on each other, I could see the pleading look. The need for both of us to cum. As I began to speed up, my own orgasm taking over my body, I. I was shivering with fear and cock was dying to get free in my boxers. I saw my sisters’ boobs, brown nipples. Wowwwwww! First time in life seeing a girls boobs. I was ecstatic. I was very horny and wanted to taste them but fear was in mind if she is awake and says anything i would be shamed. After a pounding 5 mins or thinking and enjoying viewing her boobs i decided to kiss them so she doesn’t get up. I got near hear and kissed her nipples very softly. Amazing feeling it was. Now i got more.
