So 2 weeks ago i got a snap when i was at work from the gym buddy of my gf. i thought nothing of it at first i knew they went to the gym. So in my breake i opened the snap and i saw that my gf was riding his cock what seemed to be without any condom. So i send a text back to him saying that im mad and that this was his idea probably. So i got a snap back an hour later with his dick near my gfs pussy with: round one was so good we go for round 2. ( i saw that his dick was really big)

So when i got home i went straight to my gf and asked her what was going on. And she started telling everything that she began because at the gym she saw his boner trough his pants and that it was so big that she wanted to try. And i got an instant boner myself. So she told her whole story of what they did and i almost cummed in my pants without touching myself.

Then i asked if he had cummed inside her (i never did that) she told my yes 3 times!

That was the moment i cummed.

And after we had amazing sex!
