Topless, lustfully, and seductively she approached us. She went straight to Rob. She wrapped one arm around his neck as she kissed him, and her other hand went directly to his crotch. Seeing Carrie in heat like this really had me turned on. Rob and I had never discussed a threesome before, so I was not quite sure what to do now. Almost instinctively, I reacted by pulling out my cock, and I started to stroke it.
I watched as Rob took Carrie's nipples into his mouth and I heard her sweet and sexy moan. Carrie looked over at me and licked her lips when she saw my cock in my hands. She stepped away from Rob and got down to her knees in front of me. She pushed me back against the frame of the deck and tugged my jeans down around my ankles. She took hold of my cock and then lowered her mouth over it.
Her mouth was warm and wet. She rolled her tongue around my shaft as her head bobbed up and down over my cock. Rob smiled at me as he bent down behind Carrie. He pulled down her bikini, then raised her ass and spread her legs. I couldn't see what Rob was doing but judging from her muffled moans and her now frenetic pace sucking my cock I knew he was giving her pussy a good tongue fucking. I held her head down on my cock and gyrated my hips pumping my cock into her hungry mouth. She held my cock firmly in her mouth as her body shook from her first orgasm of the day.
Rob took Carrie by the hand and started leading her back to the lawn chair. Carrie took my hand leading me to follow them. Rob sat down on the chair and guided Carrie to straddle him. Carrie grabbed Rob's cock and held it as she slowly lowered herself down onto him swallowing his cock inside of her. Rob played with her nipples as her breasts bounced up and down as she rode him.
I bent down behind Carrie and pushed a finger into her ass to see if she would like it. The presence of my finger in her ass made her fuck Rob faster, so I started fingering her ass while she fucked him.
Carrie was moaning with pleasure and she told me to get my finger out of her ass and stick my cock in there. I spit into my hand to lube up my cock and then I got on top of her and pressed my cock into her ass. Her ass was nice and tight.
Carrie moaned in pleasure as Rob and I both pumped her with our cocks. Fuck me! Fuck me! I am coming again! She squealed as her second orgasm rocked her. As she hit her climax I felt her ass tighten around my cock, the sensation was more than I could handle and she made me explode into her ass. As I finished emptying into her ass Rob started to erupt in her pussy.
When we were all done, Carrie licked our cocks clean of any juices left on them, and then she went upstairs to shower. Rob and I got dressed, and when our strength came back, we finished our work on the deck. He told me that Carrie always thought that I was the hottest of his guy friends and that she had been interested in getting me into a threesome for a while now. I told Rob that I still thought he was the luckiest guy in the world but now I felt like the second luckiest guy in the world. He smiled and suggested that we go upstairs to see if Carrie had gotten out of the shower yet.
