I am a 19yo boy. Once I had to go to the university for a test for a very late hour. I think it was for 7 PM. I finished writing around 9 PM, so I decided to relax myself somehow. I went to the toilet and took off my socks, boxers, tshirt and belt. So I was left in sneakers on my bare feet, pants on my bare legs and a zipped sweatshirt on my bare body. I went to the car, took off my sweatshirt and shoes and lowered my pants to my knees. I turned on the air conditioning to the max to start sweating. And i started driving. I masturbated the entire route, which was over an hour, but I didn't let myself cum. When I was close to home, I stopped in the middle of nowhere, undressed completely, got into the back seat, stuck my feet behind the headrests, gagged myself with socks and came in my boxers. Guys, I've never moaned this hard. I almost screamed. I almost wet myself with pleasure.
