I have a girlfriend that I went to school with in my hometown that I see when I visit.
She is very enthusiastic in matters related to sex, and has assumed the role of a cuckold wife with me being the cuck, and loves to share her pussy with others for my pleasure. Not to mention hers....
She has fucked another friend in particular, also a school mate from back in the day. He is very dominant with her, and is aware she shares all details with me and knows that I like her fucking him. As matter of fact, I listened over the phone one time of them having sex, including him taking her butt cherry!
She had arranged a 3-way with him and me a few years back. After an informal reunion of her class, he was supposed to meet us at our hotel, but things fell apart at the last minute and it never happened.
The point to all this is we have fantasized about it many, many times, and she has asked him about it when they get together to fuck, as we have when we are together.
I've told her that I see me being as submissive to him as she is, so she has told him I would like to suck his dick, and I want to clean it after he has cum in her pussy or have him pull out and cum in my mouth. She also told him that she would "set me up" and have me eat her pussy with my ass in the air, and that if he would get behind me to fuck me, I wouldn't stop him.
And it's all true.
So if it were to actually ever happen, that would be my next bi experience. I hope it does.
I'd still like to know what it feels like to have a hard cock in my hand, mouth, and/or ass. Eating cum or taking a load in my ass would be a great bonus!
