I whispered that I was going to fuck her up the ass. She moved backwards against me, then reached between her legs to find my cock. She directed my co...k head to her opening and pushed hard, impaling herself on my semi hard cock. That refreshed my erection to 100%, so I pushed balls deep inside her ass, and began thrusting. She was moaning and humping against my cock, so I knew I wouldn’t last long. It happened again; movement on the stairs, but I was too far gone to stop. I pumped her ass hard. Most times Cheryl got to sleep with them…and have sex with them too.On that rare occasion, a girl would ask if she could sleep with me, knowing full well what was going to happen.I got to fuck two girls that way. Both were virgins. I was only a virgin that first time. Each morning after I fucked them again, Mom insisted that she lick my cum out of them. I told you that Mom liked young teenage girls.Then Cheryl turned thirteen herself. That was when Mom invited all of the girls to a weekend. If she didn’t manage to get him right to the very edge, or fairly close to it, his frustration would slowly fade. She’d never known a man who didn’t suffer ‘blue-balls’ before. On the other hand she was just about ready to drag him away. She knew the house well and could probably discover an open bedroom. Her mind set she looked to the dance corner and discovered him missing. Her smile began to fade as she realized her cup was empty. He hadn’t been through to get her drink so he hadn’t gone to. "I gave her a nice hand-job before leaving - she gets real complacent after she orgasms. So don't bring up what happened this afternoon okay?"My eyes trailed down to the one hand above the table, wondering if those were the fingers that had been inside my mother's sex.Taking a sip of water, my mouth having become so dry, I asked, "You want me to pretend it never happened?"Dan looked at me for a second, perhaps reading me before answering, "No not that buddy - I have a better idea." He leaned in.
