"Judging from that dungeon I expect they think about sex almost as much as we do. And I'm sure they remember what was always the top topic when they w...ere our age." You mean they knew about sex way back in their day?" Then he became a little more serious. "OK. I guess, much as I don't like the idea, we'd better get dressed."Lisa made a face, but nodded. "Yeah, you're right. But first, come here a second." When Dan came over she wrapped her arms around his neck and pulled their bare bodies. I sat there watching his chest rise and fall as he slept. When he stirred I asked, " what's your name?" Bill. Just Bill." He answered, "You gotta piss?" Yes." I wanted to at least stand-up and stretch. But using the facilities was also a consideration. Bill stood in front of me and said, "You want to use the can. Blow me.". He dropped his shorts and tossed them on the cot. His cock was a good three inches longer than mine but it was less thick. A couple pulls on his shaft and Bill aimed. He loved his cock in her tight hole and loved feeling her cum against his big meat. His hands reached up and began rubbing her tits as he fucked her hard and deep. She grabbed one of his hands and moved it to her clit and he knew she wanted it nasty. He gave her clit and two finger rub and pulled on it and watched her move her hips on his cock. It was a short but rough fuck till he filled her with cum. He then grabbed her and pulled her pussy up to his face and he sucked the mixture of cum out. " God, you two!" said Lissa. "Or should I say, you four. Or six. I thought I was naughty, but then I come home and find out my little brother and sister are even worse. I'm going to have to try extra hard to catch up." Good luck on that, because we're going to be working hard too." In that case, Jeff, are you up for seconds?" asked Lissa. "After Brit's praise of your cum, I want my share."He nodded. Before she went to work though, she began stripping off her clothes."You don't mind, do you.
