You really should try it, you will love it. That is when my wife had her strongest orgasms!I've never had a guy eat his, or someone else's cum out of me, but there was a period in my life not long ago that involved me wanting to have a co-worker do this to me. I know it sounds bitchy, but he was/is a very beta kind of man and I used to imagine he was still a virgin (I'm guessing he is 22-25 years old.) Some of the other women at work sort of adopted him, and I think it only made him worse off. He just seems so awkward, and shows no confidence. Mind you, he's a good looking guy, and I'm sure he could be dating, but not with the cringey behavior he has.
For whatever reason I had started fantasizing about him licking my pussy while my guy watched, and then waiting patiently until my guy finished inside of me, and then having the awkward guy come back and lick me clean.
I'm sure there had to be some kind of behind-the-scenes reason I wanted him this way, it wasn't sexual as far as my wanting orgasms from him, maybe I just imagined he'd grow a pair and stop being so strange.
In any case, I haven't had this happen, but I think under the right circumstances, I'd really like it to.
