I don’t currently have the time to flesh all of these out so I just wanted to list some experiences.
WAAYYYY back in the mid-2000s before every person who had seen 50 Shades of Grey or had determined their relationships were boring it was pretty easy to find truly kinky people to hang out with.
These were some of my experiences. I’m a bi male btw.
Had a threesome with a woman and her bi husband. She was a teacher and wanted to roleplay that I and her husband were two students who needed to learn to suck dick and fuck each other. I ended up licking a huge, thick load of cum from between her ass cheeks at the end.
Met up with a couple plus their mutual girlfriend at a casino and had a foursome that lasted for 5 hours. I gave so much oral that my jaw was sore the next day.
With the same couple I spoke of first, got together with them and two of their friends (one male, one female) and I was fucked in my ass for so long I orgasmed 3 times and passed out I was so tired. When I woke an hour later I had a pussy grinding on my face.
