I have a fantasy with my friend

I (27M) already have a boyfriend, and we have been a couple for 8 years now, I really love him and I’m not the kind of person to cheat. I’d rather be single and wild than to be a cheater. Recently I’ve made some friends, one of them (25M) says he’s not gay but he’s already had relations with another man and he confessed to us that he has a dildo and likes using it because of the male g-spot location.

Now the good part is that ever since he said that, I can only imagine myself fucking him with his own dildo and edging him till the point where he asks me to fuck him, to which I oblige until he cums all over both of us. I’ve jerked off to the idea multiple times already and I can’t seem to get the thought out of my head since I haven’t said it to anyone.

And I clearly don’t want to say it to him cause I don’t want to lose the friendship, either due to rejection or to interest since even if he wants to, I just won’t do it.

Btw, I just fantasize with this because I don’t seek a relationship with my friend, just a one night stand and that’s it, but anyways.

I just needed to share this
