I had picked up my girlfriend and went for a burger. When we got back to her house, I parked the car and as always we started making out and feeling e...ch other. We would usually end up fucking in the front seat of my ‘67 Chrysler, but she had started her period so I was out of luck. However, I could still feel her nice firm tits and suck on her hard nipples which I happily did. We leaned back for a breather when she reached over and pulled my hard 6” cock out. She then leaned over and swallowed. It wasn’t that our life in bed was dull, we still had plenty of fun but had both enjoyed bisexual experiences before we met and had long talked about exploring this side of our sexualities again at some point.Dom was a lot younger than me at thirty-five compared to my forty-eight years and I was always proud to have her on my arm - she’s a pretty petite brunette with long flowing hair, green eyes, lovely firm 34b breasts, and a nicely curved ass.I thought I looked pretty good for my age though. I slipped a hand down the front of her dress and squeezed a nipple. Heather whimpered but there was no let up in the wildness of her riding of my cock. The noise built around us. The fervour of the crowd augmented my excitement at being fucked in this most public of places. My tongue was deep inside her mouth lashing wildly in a demented tango with her tongue. My hands went under her dress to her bum. Pulling her cheeks apart. Running my fingers from her cunt to her arsehole. Playing with that. I asked how he slept, and he said naked. I said that I would too though I never had. We stripped off our clothes trying to look at each other quickly. He had a defined chest with medium size nipples. His body was hairless except for the dark bush from which his large flaccid dick hung from. I did look a bit long but did not stare. He saw my flat chest that was like a board down to my thick bush and big dick. Our cocks appeared to be the same size. We climbed in bed and talked about.
