Seeing and fucking her half-naked felt so dangerous and dirty, even more so in a powder room.Our juices were overflowing between us and watching her f...uck me just took me closer to the edge. She began lifting herself closer into me, rubbing my bud and grabbing mouthfuls of my aching tits all the while I fucked her harder.My body felt waves of bliss from within radiating itself into a shuddering motion. My fucking became more intense as I let the orgasm ride through me into her. She felt it. Molly's weakness was girl/girl sex, and we used to laugh about her interest in that. I told her about a new site that she might be interested in. Otherwise, it was chit-chat between two married people. Whether I could keep it up when Molly came home remained to be seen. What would really be difficult would be when the four of us were together. And that would be on Saturday, when Anne and Jackson had invited us over for another cookout. I got home from work and Molly's car was in the garage. She. He didn't take any time to warm up and I didn't think either of us needed it anyway. It took a minute to figure out how to get it to work, but as soon as he did, he plunged the full length into me. I let out a yelp and he stopped. "Are you ok," he asked as he looked me in the eyes. "Oh yeah. That wasn't a painful yelp," I said as I started to rock back and forth on his cock.Getting the hint, he began to plunge himself into me with force. I couldn't think. The pleasure of it all was. As we did so, I felt his solid young shaft twitching against the sensitive curve of my inner thigh. Feeling this too, he proceeded to goad me with it playfully, working the tension between us up into fever pitch. The sexual chemistry between he and I was indescribable. As I felt his thick swollen tip press into me and gently prize me open, I finally learnt the meaning of hot, passionate sex. I breathed in the sweet clean smell of him, nuzzling my face into his neck, all the while his fine cock.
