"There you gooo," he sighed."OOhh! It's ... I feel soo ... so full!" Full of cock, Sarah. Full of cock! Just like you were made for."He pulled back a ...few inches, then thrust forward. She gasped and lurched forward. He pulled back again, then thrust in sharply. He ground his hips against her ass and then slapped her again."Oww!" Yeah! Yeah!" he gasped.He slid his boner back down her ass tunnel until only the head remained, then drove it right back into her. He didn't care if she was only. I'm into sloppy seconds, both literally with my cock, and gorging on them as they ooze from a freshly-fucked, hot pussy. That pussy, by the way, is usually my sister and the cum is usually my good pal Paul.How does one become interested in such a "fetish"? Who can say? One day this brilliant idea forms in your head and then you get to work trying to make it reality, getting my sister to go for it, and the friend!I think that the three of us being so familiar with one another and such good. I changed myself in night dress. We slept in the bed next to each other. I pulled the blanket, it was double size. We both covered ourselves up to our belly. It was cool, but not very cold. She was on my left, she turned to my side, I turned towards her. We looked at each other. I asked what her plans are for tomorrow.She said, tomorrow she has to report office before 1 pm. Training may start from Monday, on Sunday she want my company for shopping. I assured her, that sure I shall accompany. I moved my hand to her breast and started gently fondling her left breast over her top. She moaned. I moved down from her lips to her jaw and then to her neck and started kissing her neck. She had started giving loud moans now.I licked her neck and bit her neck gently. Meanwhile, I had moved my hand to her back and started touching all over her back. She was all in my grasp now. She wanted it more than I did at this point of time. She had missed my touch too. She had missed the feel of my lips.
