My gf got creampied by a men without letting me know

We’ve been in this lifestyle for a while now and her body count so far is 11. (I'm her first man)

But speaking of the hottest experience with her, it will always be that one time she let a man cum inside her without letting me know, and come home to have sex with me with a cum filled pussy.

That man was our second bull in this lifestyle, and she was 18 when this all happened. I still rmb that day she came home very horny, teasing me to fuck her. (Which is very rare, she usually doesn't tease me) After undressing her, I found out her pussy already soaking wet. Apparently, it was cum in her pussy, but I was too stupid to find out and think it's because she's horny. While I'm fucking her, I can feel her pussy was way wetter than usual and literally feel it's dripping out. I asked her why is she so wet that day, and she said because she wanna get fucked so bad.

After a year, during sex, she finally unveiled the truth.

“Do u rmb one time my pussy was so wet when we fucked?”
“Yea, what about it?”
“Its someone else's cum, I let someone cum inside me before I came home that day.”

At first, I was pissed that she cheated on me. She immediately apologized and promised that would never happen again, but soon, she started to blame this on me.

“It's because u wanted me to fuck other men, I'm just doing what u say.”

I can't argue with her but keep pounding her hard and have the best sex we ever had.

P.s. One of the side effects of this story is I will never know her fucking other dudes behind me again. The initial reaction that im pissed was kinda pushing her away from telling me the truth. She has a lot of pretty close boyfriends, but I’ll never know whether they’re fucking or not. Never.
