While having sex the Mrs. & I used to discuss what we lied about the cocks in the videos we were watching, being bi we had a desire for nice cocks in common. She seemed to always be interested in the thicker 1's. I asked, "If we were to try swinging, she could "window shop" then decide if she'd like to give herself to another, thicker man. We were at the bar when 1 of the guys she'd been eyeing asked her to play. He was standing right in front of her with his fairly large cock in full view for her. Being shy, I was her 1st & only at that point, she was unsure about it. I told her to grab his cock & see how it felt. She did & as she held him in her hand he started to get hard & even bigger. She said OMG as she watched it grow, I encouraged her to stroke him, she did & he got fully hard. I told her it was decision time! Was she gonna fuck him or not...She went with him but asked if he minded if I came also, he didn't. We went to the play room where we all got busy. He eating her pussy, me sucking her nips & kissing her. He got up & asked if he could enter her, she said yes! I lay there watching him enter her as I heard her gasp as he started put the biggest cock she'd ever had slowly in her. They fucked for about 20 minutes & she must have cum 4, 5 times before he finally stiffened & shot his load in her! I waited for him to pull out then I entered her & gave her a couple more orgasms before I came. That was also my 1st time getting to fuck my wife's hot & sloppy pussy with another mans cum in her! So, let the talk continue, but beware if either of you is the jelious type.
