Ashamed Of My Community Service To The Homeless

Ok, while I'm confessing stuff...
2 weeks ago I was in my car waiting for my uncle. It was dark, I had an hour to wait, I was horny. I decided to play with myself while chatting online... the guy I was talking to told me to take my top off lay back and start fingering .... so I did and keep chatting. Next I look out window and 2 of the homeless guys are watching me , tits out , in a car in a dark carpark, fingering myself. I quickly covered up and motioned for them to go away. They were about 5m away so I opened my door and told them to leave me alone, they said they were enjoying the show why did I stop. I said because of them. They came over and I stood up so I wasn't down lower than them. They pushed me back against car and pulled on my top Re exposing my tits, one held my hands back and started sucking on my tits the other fondling my wet c**t. I don't mind having aex with men if they want it but these guys were clearly homeless. However I couldn't help but stay wet and horny. They took turns fucking me against the car bent over the hood. I didn't have protection so they both came in me twice. I felt yuck after because they were homeless but then thought actually I let everyone else fuck me why should I say no to them. I went back last week to get fucked again. Next time they'll have friends.
