We had met him for what was to be our first three-sum. How things developed was left up to my wife. We took the guy out in our boat to a sandbar on the river. My wife was slow getting things going. I had given up on her, when she removed the top of her swimsuit, then the bottoms, and joined the guy in the water. She was standing in front of him as he removed his trunks. She then reached down between his legs and placed his 9-inch dick between her legs. He started to push his dick into her pussy. As he entered her, her head went back, and she let out a moan. As he started to stroke it in and out of her, she really got into it. They were standing in waist-deep water. I was standing beside her. She was telling him how good he felt inside her. I could tell she was building to a climax. Then her head went back, and her body started to shudder. He pushed deep inside her and held it. She moaned, "Yess! Cum in me. Damn yes, I feel you. Fill me with your hot cum." That's when it hit me that he was filling her with his cum. He was shooting his cum deep inside her pussy, flooding her cervix with his seed. We had forgotten to use the condoms. After a rest, she got us both out of the water onto the bank, where she got on her knees. Soon he was fucking her doggie-style, as she sucked my dick. It didn't take me long to cum. She then lay on her back, telling him she wanted ALL of his big dick in her. He got on his knees between her legs, and really started to work her pussy over with his long dick. From where I was I could watch every stroke of his dick as it moved in and out of her wet and willing pussy. She had a number of climaxes before he again pushed it deep inside her, once again filling her pussy with his thick hot cum. There wasn't a reason to use a condom that time. The damage (if any) had already been done. My wife has invited me to set up a half dozen three-sums for her since that time at the river. Most of the time (but not always) we get the guys to use condoms now. We know it is safer that way, but to be honest, I get a kick out of screwing my wife when she is full of another guy's juice.
