I'm so embarrassed

So I have a little story, work with me here this is my first post to this page😂. My fiance is in treatment for previous drugs. I'm super proud of him and he is doing great, well today was visitation, next to his facility is a park that they go to during the visitation. Well him and I went to the end of the park so we could be away from other families and he could smoke a cigarette as well. He has been in for a while, and before he left we would have sex usually a couple times a day, then him being in for a month without even masterbating. Well we started talking dirty, and he brought up everything that makes me tick. So I'm there

Then I look down and see that he has a boner, he starts begging for it, saying things like please please, it won't take long, I need you. So I end up saying screw it.

He pulls his sweatshirt over him, and I had a hole in my pants that he did his thing with. And I proceeded to give him a handy in the middle of this damn park, in front of God and everybody. Luckily no one besides one couple walking by that we were friends with saw but then I see his administrator.

His admin used to be a previous porn star, and as I'm doing my thing he walks near us smiles, pats his own chest twice and says "You the real MVP" then walked away. Shortly after he finished and we had to go back Inside.
