Seyla climbed off of me, gasping in at the loss of my penis from her. She knelt down onto the floor of the hot tub and placed her hands on the edge of...the tub out of the water. I knelt down behind her, positioned to enter her from behind. I grasped myself in my hand and guided my penis to her opening. I pushed in and Seyla gave a slight moan. I grabbed a hold of her hips with me hands and began pushing and pulling Seyla off of me, thrusting my hips as I did. Occasionally as I thrust in and out. She pulled him closer until she could reach his cock with her mouth. Bret continued to stroke himself while Laura tongued and nibbled the head of his cock, paying special attention to his frenum, that sensitive spot on the underside just beyond the head. She was expert at oral pleasure, and I loved watching her. He rocked back and forth, sliding his cock across her lips, occasionally pushing the tip into her mouth. She explored his shaft with her tongue, thoroughly licking his erection.I got on. I saw my dad push hard and knew that he was cumming in my wife’s willing cunt. That drove me over the edge and I gushed everything I had into Terri.We laid there together for a little while, not talking, just stroking each others bodies. As I watched my wife lying there naked, her legs slightly spread, my cock began to harden and I knew that I wanted her as never before. I moved over to her and gave her a long kiss. She pulled my body over hers and reached for my cock. Barbara fed me into her. I knew she was a bit of a hippy back in the 70's and would probably be up for it. Which she was. I suppose Helen was quite attractive and looked good for her age. She was quite fashionable, looked after herself, and had long blonde hair and decent looking figure, although she was probably a bit too thin if anything. It must have been the combination of alcohol and weed that turned the conversation sexual, and she was quizzing me about why I didn't have a serious girlfriend and wasn't I fed up.
