He pulled his prick back a second time, then slid the long column slowly into her cunt again. That felt very good to him. He stroked out and in, out a...d in, setting a slow, steady rhythm and penetrating deeply with each thrust.Kathy gasped, then whimpered. Her hips began to move cautiously against him. She was really getting with it now. She moved more actively, taking her brother's cock even deeper into her teen body.Soon they were driving their crotches together. Kathy punctuated the rhythm. Working late became a weekly event and business trips away turned in to dirty sex sessions in hotels. Helen had got her man and she was loving it, better sex a bigger cock than her husband and a man happy to spend some money on her into the bargain.

I pressed my books into my breasts, trying to fondle myself without anyone noticing. I turned into a incove that had the largest trees in the park.

God those men were so sexy...I spread my legs and began to rub myself through my pants, using my palm to rub my lips slowly. It had been a while since I'd last touch. If they come around the steps they are gonna see." Shut up. They are adults. I want to suck your cock before I go to sleep."The chance of getting caught by my daughter and her hot friend was exciting. I placed my hands on the back of my wife's head and started to face fuck her while she was sucking me. My wife has never been great at giving head, but there have been times, like that night, when she was drunk enough to be lose, but still sober enough to have her wits, that she would suck me like.
