You found a guy online and he fucked you in the back seat

Yeah I don't know, it wasn't supposed to go like that but the door was already shut and the car smelled like old leather and his cologne or whatever that shit was. I had on these white tights I'd bought the week before, stupid cheap ones from the drugstore that kept riding up my ass, and nothing else except the little thong underneath because he told me to. He'd grabbed my hair right when I tried to sit up, yanked it back so my neck hurt, and I was on my elbows looking over my shoulder while he lined up behind me. His chest was all shiny with sweat, abs flexing every time he shifted his hips. The window was fogged on the passenger side. Some guy walking past the parking lot probably saw us but I didn't care enough to stop. He pushed in slow at first then just went for it, no warning, and I made this noise I didn't recognize. Like a whine. My face was pressed into the seat and I could feel the seam digging into my cheek while he held my head down with one hand and fucked me like I owed him money. The tights were pulled halfway down my thighs, bunching up, and every thrust made this wet sound that echoed off the roof. I kept looking back because I couldn't help it, kept checking to see if he was even watching me or if he was just using the hole. His face looked bored almost. Focused. Like he was trying to get somewhere specific and my body was just the route. My cock was trapped against the seat, leaking through the thong, making a spot. Every time he bottomed out it rubbed and I got closer without meaning to. He noticed. Laughed once under his breath and said something about how quick I turned into a slut but I didn't catch the rest because he started going faster. My arms were shaking trying to hold myself up. One knee kept slipping on the leather. The whole backseat was creaking. I came first. Didn't even touch myself, just shot into the fabric and made this pathetic sound and he didn't stop, just kept using me through it until everything felt oversensitive and raw. He finished a minute later, pulled out without saying anything and wiped himself on the back of my thigh like I was a towel. Then he checked his phone while I was still bent over catching my breath. The tights were ruined. I had to walk to the train like that, wet spot drying on my leg, hair stuck to my forehead. Told myself it was a one time thing but I already saved his number under a different name in case he texts again.
