After a few minutes of this she got up and we were back to kissing, I lifted her up by her ass and stretched it wide open, all while we still kissed d...ep.Now I threw her on the bed with me on top of her, our bodies still hugging as tight as they can and our lips locked. I could feel her boobs pressed hard against my chest as I positioned my penis right on her pussy , and slowly pushed it in till it was all the way inside. She wrapped her arms around my back pulling me closer to her. She was. Her tits stood out proudly, the nipples erect and pointing in my direction.Jill also seemed to like what she saw. A perky grin appeared on her face when she saw my erection struggling back to life. She leaned all the way forward, and took the tip in her mouth. Both of the sisters have been pretty limber as long as I've known them, able to lay their body out flat along their legs, with their heads against their feet. I carried on massaging the flats of her feet, while she gave me the beginnings. I knew that this would mean that I couldn't just get out whenever I wanted to so it was perfect for my needs.I left my left hand in the loop and made sure that the rope wouldn't get too loose and the cinch would remain there, just loose enough to allow my right wrist to slip back in when it came the time for that. But now came the time for what I had been waiting for as long as I had gotten that email the previous day. I would get to try out my brand new gag.As wonderful as the situation was,. Carol stopped. She looked at me sadly."Don't say things you don't mean. I'm fucking you for free anyway." I mean it." I said. "I'll marry you right now."She looked into my eyes. Her wrinkled face half smiling half frowning. "You serious?" Yeah. I'll marry you Carol." "Linda. My real name is Linda Wittam". "My mother's name", I thought"And I know someone who can marry us." Carol and I spent the night together, fucking each other. She brought out her strapons and fucked me silly and I fucked her.
