Me and this girl I was hooking up with were driving down the highway at dusk, so it was mostly dark but not completely and I didnt have tinted windows. It was so dead that she decided to unzip my pants and start playing with me, she already edged me earlier that day but decided it was a good time to go again. She started with jerking me off and even sucked it for awhile. Since it was so dead I even lifted up her skirt, slid her panties to the side and start rubbing her clit. We were both feeling so good and moaning loud, my dick was throbbing and leaking out precum. I kept my eyes in the road but had no sense of what was going on in other lanes.

We got to red light and as we were enjoying our time we heard a noise outside. We looked over to the left window and saw a car there with two ladies with the window cracked open a bit, just enough to hear that they were yelling and giggling in a cheerful/catcall type of way, and even motioned as if they were telling my girl to keep jerking me off. My girl was not bothered at all by this, she rolled down the windows and started talking back like "oh yeah? is this what you wanted to see?" and went down on me, she was so sloppy with it and sucking me as if she was trying to show off for them. I could hear them cheering even louder as I was having the time of my life. She switched to jerking me so she could continue talking back to them but I dont think she realized how I was feeling, becasue I was close. I was trying to warn her that I was about to cum and it was till right before that she noticed. I couldnt hold it back anymore, so much pressure in my dick from the edging before and during our car ride got to me. The first rope shot out in our car and she instinctively pointed my dick at our open window facing the girls car. I have hyperspermia so when I cum I cum hard, especially after a being edged, so I ended up shooting my load all over their window. I could hear them gasping and saying things like OMG or HES CUMMING, I think some even got in though the small crack in the window. I was surprised but I got a good amount of cum on their window, to the point you would question it driving by. I looked and they had a shocked expression but it was almost like a good shock (the partial smile, mouth open type of look). My girl was turned on and giggling about it but I was embarassed, that post nut clarity hit me like a truck. I looked back and the light was already green, so I just stepped on the gas and tried to get away asap.

Ive always seen some crazy stories on this app and thought "ofc this is some crazy reddit story that never happened", but after that experience I accepted anything is possible if your girl is crazy/kinky enough to try it lol
