A GF was trying to "set me up" to get fucked by a guy she was fucking at the time.
Like a lot of women, she fantasizes heavily about her BF or husband sucking and fucking with another man while she watches.
She was fucking this other guy and me at the same time ,and was telling him I was interested; I would suck his dick, and would let him fuck my ass. She would tell me his reactions, and ask how I liked them.
She was trying to manipulate us both, but the truth was I wanted to submit to him.
She had planned a 3-way for us, and told him if he got behind me while i was bent over, I wouldn't stop him if he stuck his dick in me.
However, she did NOT tell ME this, and was going to get me to eat her pussy so it would ****** my ass, and this is when he would fuck me.
So, it was a definite set-up, our 3-way didn't happen, but I still have fantasies about having to submit to his dick.
