I had this weird threesome with my ex who still loved me and this random slut.
It happened in my exs parents car in their driveway.

My ex who usually was kind of submissive was kind of rebellious from the jealousy so she took the lead in the threesome. She loved anal and was a master of it. She could easily take my pretty thick penis without any preparation. The only problem was her rectum was often not very clean (I was usually happy to fuck ass and did not care that much).

So she was the first one to fuck and she just sat down on me inserting my dick in her butt and rode me.

When she got up it was dirty. Not like full of shit but brownish slimy and a bit smelly.
Slut wanted my dick too but no way she would take it like this. (No condoms because we were young, drunk and stupid)
So she told my ex to clean it. We also had no tissues so ex asked the slut if we could use her shirt which escalated the situation and they had a real argument. They were already kind of competitive and therefore unfriendly and provocative towards each other the whole evening.
Slut half jokingly told ex that she had to suck it clean and ex refused.

The thing was I really wanted to fuck this slut. She was much hotter than my ex and we were flirting the whole evening already before my ex intruded and almost ruined it.
And now she was very close to ruining it again. So I got a bit mad.

I grabbed her by the neck and pushed her down to my cock. She did not open her mouth at first so I rubbed it all over her face.
Then I opened her mouth with my other hand and forced my dick inside.
I am very happy she did not just bite me but she was such a good soul. She would never hurt a fly.
When I was inside I grabbed her by her hair and fucked her mouth. She cried but eventually she came to terms with her situations and actually sucked me clean.

The rest of the threesome was much more harmonious since my ex stopped acting bossy like she did at first.
Miss you Klara!
