My friend [M,33] fingered me [F] in the backseat of his gf’s car while she was driving

We were driving to the bar and there was 4 of us in the car, my 2 male friends (friend A & B) and one of their gf’s was driving. My male friends knew I was a slut and they’ve both told me on multiple occasions they wanted to fuck me. I was sat in the back of the car with one of them, and wearing a short pvc skirt, thigh high socks & thong with my bag on my lap. I guess this was an opportunity for friend A, as when we were talking he discreetly put his hand on my thigh and started stroking it. It was way too awkward to even look at him at this point but I know he could tell I wanted it. He slowly put his hand up my skirt and started rubbing my pussy over my thong. I kept looking at his gf to make sure she wasn’t aware of what he was doing. She wasn’t. He pulled my thong to the side and started stroking my clit with 2 fingers. I started getting really wet at this point and he put a finger inside me which led to two fingers and he finger fucked me for what felt like 5 minutes. I’m really good at being quiet when I need to be but he was going at me so hard I moaned. The music in the car was too loud for anyone to hear me (I hoped.) Eventually we got to the car park. We got out out car, he had my cum on his fingers and I went through the whole night with this dirty secret, feeling super naughty and nobody had a clue
