My head was still spinning from everything as I lay there watching Mary adjust the straps on the harness that held the dildo. She pulled and shifted them until the big fake cock hung erect in front of her. She picked up a bottle of lube and began spreading it over the length of the shaft. I could feel my stomach begin to tighten in anticipation of what was to come. She crawled back onto the bed and knelt between my legs. Holding the glistening cock in her hands I could feel her slowly rubbing it up and down my slit. Slowly she worked the head into me. It was so big and firm and it took a moment to adjust to the size of it. With a slow deliberate pace she began to stroke in and out of me. She leaned forward and kissed me. I felt her cock slide fully to my depths. I felt so full as she held it there while we kissed. I took her tits in my hands when she leaned back up and I rose up to suck each nipple. Flicking my tongue over them each in turn; as I watched them stiffen. My thoughts were wondering everywhere at this point. I had never imagined myself in this position and I was feeling nervous and unsure yet I was incredibly turned on. I reached over and took Jim's limp cock in my hand and began to stroke him lightly. I could feel him begin to swell in my hand. I pulled him closer so I could take him in my mouth. As I sucked his cock I could feel him swell to hardness as it now stretched my mouth with its circumference.
I have never had rough sex. Sex for me has always been more subdued and sensual. As Mary began to pump into me harder I experienced feelings I had never had before. She pulled my legs up over her shoulders and began to fuck me in earnest. My body rocked with each thrust as she seemed to fuck me harder and harder. She was fucking me so deep and hard she was hitting things that have never been hit before. I think she may have found my g-spot because in seconds I started to come like never before. It was a very deep orgasm that originated from somewhere deep inside me and rocked through my whole body. I dropped Jim's cock from my mouth and lay my head back. Involuntarily my head shook form side to side as I cried out. Mary didn't slow down and I couldn't stop coming. It seemed to just go on and on as she fucked me hard and deep. Finally she seemed to take mercy on me and slowed her pace and allowed me to catch my breath.
She looked down at me smiling, "I think you liked that."
I could barely talk, "Oh yes I did."
Mary let her cock slide out of me and lay down beside me on her back. "Why don't you try it on top a while?"
I moved over her and lowered my pussy down on her cock. I took it fully and just sat there looking down at this beautiful woman. I reached down and held her tits as I began to rock slowly on her. I could tell be the way she was moaning she liked it as much as I did when I pumped harder. Jim knelt beside her and fed his cock into her mouth. She stroked him as she sucked his head. It was so hot watching her suck him while I fucked her I couldn't resist laying down on her and sucking him with her. We took turns taking him into our mouths while she stroked him. Out tongues would meet on the head of his cock as we sandwiched him between our mouths. Jim pulled back and let me kiss her deeply. I couldn't get enough of her soft mouth and wet kisses. I saw Jim out of the corner of my eye lubing his cock up. I was unsure of his intentions but had a feeling where he was headed.
