Note: This story was dynamically reformatted for online reading convenience. The three of us, Dave, my fiancee, and me, had one night of sexual fun a couple nights before. I thought it'd be exciting to take my sexy fiancee out with us and watch her dance in public with another man. Dave was game for it. He took us in his big Oldsmobile to a country and western bar he liked. It was kind of a slow night at the place, but we danced with Julie plenty of times. I'm sure she enjoyed it, having both us men wanting her to dance with us. We left early and Dave drove us back to the rooming house. When I opened the door to my room, Julie and Dave came in behind me. Right away they started kissing and groping each other. Wow, I hadn't expected things to go so fast. They were hot for each other: it had been a couple days since our threesome together. They kissed and groped and hugged each other just a minute, then Julie dropped to her back right on the spot; in a flash she had her pants down, and pulled one leg out of them so she could spread her legs for Dave. He had his pants down right away too, and they fucked. I was sort of stunned; I just stood there as Dave fucked my girlfriend; Julie's warm wet cunt brought him to the edge in seconds. I remember watching him raise up on his left arm so he could pull his cock out and stroke it; this sent a mighty spray of cum up on Julie's tits, big drops of pearly semen all over my fiancee. Quite a show! As she wiped the cum off her tits and belly, I could see she was still excited. She smiled and turned her big brown eyes up to Dave. What the hell I thought, I'm tired and have to get up early for work; it was Saturday night and they both had Sunday off; I suggested she ought to go upstairs and spend the night with Dave. They were both into it; I watched them climb the stairs arm-in-arm, Julie's cute little ass swinging side to side as she climbed barefoot away from me to Dave's room. Once they got to his room she told me "He made me suck him." The next day about mid-morning I got a rush thinking that at that moment my fiancee could be giving Dave a good-morning blow job. Julie later recapped her morning with Dave said she did indeed wake him up by sucking his dick, just for fun! Dave was one lucky dude. I was a lucky guy. I have no doubt that Julie loved having Dave's cum shooting in her mouth. It was fun sharing my girlfriend like that. I knew she really liked being with another guy. The first time they were together, the sparks really flew. Dave came in her mouth four times, and once in her pussy! And on their second night, Julie got him off again with her pussy and mouth several times. I loved fucking her afterward, knowing that warm and tight cunt of hers had been gripping and stroking another man's cock not too long before; she would be all fired up, wild to have sex.
