Sophomore Year Pt. 06

... turned slightly to make room so she could rub the inside of Mark's thighs, quickly moving to stroke his cock and balls. Mark took advantage of the change of position to run his hand over Patty's breasts and down between her thighs. Soon, they were doing everything they could to bring their sibling to orgasm.

Suddenly, Patty broke the kiss. She pushed Mark to the floor and laid down on top of him, with his cock sandwiched against her pussy. After another brief kiss, she reached between them and placed the head of his cock at her opening as she said, "I want this. If you want it too, you know how to show me."

Without a moment's hesitation, Mark drove his length into his sister's pussy. Patty moaned, "Oh god yes! Thank you! I love you!" before she locked him in another passionate kiss.

Mark broke the kiss to catch his breath. When he did, Patty sat up with her hands on his chest. As Mark reached up for her breasts, she rose up on her knees until only the tip of Mark's cock remained in her cunt, before dropping back down.

As I took a deep breath, I caught a glimpse of movement out of the corner of my eye. I turned just in time to see Teri slip out the door. Mark's jersey was on the floor nearby. I moved to retrieve it and kicked it into a corner where Mark and Patty wouldn't see it.

Mark seemed to realize suddenly that I was in the room too. He pointed to me and asked Patty, "Is this guy a voyeur or just a fifth wheel?"

Patty answered, "I'm not sure, but he has a big, hard cock, so we should let him join the party."

They got up off the floor and came to me. Mark took me in his arms and gave me a deep kiss while Patty rubbed both of our backs. When Mark broke the kiss, Patty moved in to take over.
