Thanks for the great site!
This is no biggie. When I was taking a night school course in human sexuality, my best bud's dad was taking a course in mechanical math. He took me to school and home in his pickup.
I would get excited and tell him all I learned in sex class. Even before we left the school parking lot we would would be sexed up and take out our cocks and jack off each other in his pickup which had dark tinted, no see thru windows.
Our classes were three times a week and we beat off each other three times a week for the semester. We enjoyed each other's cock so much we would sometimes jack off each other twice before getting home. My best bud and me didn't fool around. Jason (his dad) and me became regular jack off buds after we finished school for about one year when we could get together. Jason was athletic and really hung. That was the most erotic time of my life at age eighteen.
