I pulled my fingers from her pussy and began sucking them into my mouth savoring her sweet and tangy taste. We watched as the man stretched out on the...bed and the woman mounted him and began to rock, grind, and bounce on his cock, her breast dangling over the man’s face. “Sean?” Chrissie whispered my name. Her eyes were glued to the couple in front of us but, her body was all too aware of my body. I held her tightly as I slowly grinded my cock against her ass. “Yea” I moaned out as she grinded. Some of it flowed out of my mouth, which I took in my finger, got up, looked into his eyes, and licked it. “You’re a naughty girl, Sarah,” he said as he spanked my ass slowly.“This naughty girl needs your thick cock in her ass right now. Give it to me,” I said as I was desperate for a good fuck. He was completely shocked that I wanted him to fuck my ass. He was hesitant, but then I started stroking his dick again as it had gone a little limp.I was about to pull down my underwear when we heard. "I asked the doctors to run a couple extra tests on you, and they found out that you're sterile. You can't have any k**s.

I asked, wondering which tests the doctors had done to determine this. "No k**s?" I didn't know whether to jump up and cry out in elation or break down crying. Instead I ended up laughing, remembering. In their room, Melissa undressed both Charles and herself.She bent down to make his flaccid penis hard drawing it into her mouth. Once he was, she pushed him back on the bed then straddled him, impaling herself on his manhood.She slowly rode him with swiveling hips going up and down until he orgasmed his seed deep within her. She did not but it didn't matter. She received four orgasms that afternoon with her sister.Melissa knew she could weaken him and bend her husband's will to her own. While.
