Exploring New Relationship Dynamics Together

Posted an ad- couples for him.... At the time, my gf and I were having 3somes pretty regularly with some of her good friends. We were young, dumb and full of cum and just having fun. My girl was so comfortable with the fact of me, not only fucking and getting my Cock sucked by other woman, but her friends of all people. Not only was she cool with it, but she sincerely enjoyed and got turned on by it. The more we did it, the kinkier the sex got, to where she'd be holding the back of her bff hair while her bff sucked my Cock. I decided to return the favor and convinced her she could bring a guy home to our place. She was sketchy at first, but finally message a couple guys she liked, mostly by the size of their dicks, and invited one she was comfortable with over to our place. He showed up late at night and knocked. She looked at me and smiled with all her braces showing from cheek to cheek, went to the door in her thong, and walked this complete stranger into our living room shaking her bubble butt while she walked in front of him. The first night she sucked his Cock and he came in her mouth while I just sat and watched, then he left. That simple. He came by a few more times and the same thing, she'd walk him to the sofa and get on her knees and suck his Cock until he came in here mouth, them he'd leave. Finally I convinced her to fuck him instead of just sucking his Dick every time he came by. So the next time he came by, just like before, walked him in wearing a thong, got on her knees and started sucking his Cock. After a couple minutes, she popped her head up, stood, and straddled this complete strangers hard Dick. I'll never forget the look on her face when she slid onto this guy's Dick. She rode him on our sofa in front of me, bubble butt bouncing up and down for about 20 minutes. He finally started the slow moan and right before he came, she hopped off onto her knees and swallowed it all up like she'd always done before. We still see him from time to time
