I was 18 when I got into my dream school, I planned out my trip that was going to take about 17hrs. It was the most fun I ever had on a long distance road trip, I had to stop every few hours when I got extremely bored. I know it was risky but I had the money and wanted to knock out a lot of hours driving, sooo.. I got some coke which in my case makes me really horny.
So I am white, about 140 in weight and pretty small like 4'9/5'0 with shoes on. I don't call myself gay but more bi than anything, I do really love to experiment with my gay side just cause I'm young. I've really only had sex with 2 guys before and that was mostly foreplay cause their cocks were pretty big and I wanted my first one to be around 6inch with the perfect width.
At hour what felt like 100 but was only closer to 3, I felt a bit tired from starting my driving at 6am and planned to go to at least 12 I decided to take the next exit. About 3 mins later I see a sign that says rest stop so I get ready to take that exit. After parking I take my seat belt off and get to stretch, I sit sideways kind of, so I'm facing the passenger seat. I take out my coke and do a quick bump. After feeling that little rush I thought I should probably go to the bathroom so I can get going and knock off some hours driving. I lock my car and bend down to "tie my shoe" but really I just put my keys in this part behind the wheel that hides them perfectly so I don't have anything on me when going to weird places.
I'm in the stall at the far end of the bathroom which was kind of bigger than the rest but not a handicap although if it was I couldn't tell cause the room was not greatly lit or even looked kept up on. After I sit down I really thought I had to go but just went #1. I hear the door open and a couple of deep voices talking to one another but I pay it no mind more than that. I'm just about done and I'm looking around and I see 3 holes to my left all in a row and then I see some movement through a couple of them but then look back ahead. I finish up and flush and as I turn to my right there is a big black cock in the hole closet to the wall and even though it was semi-hard, it was about 5inches.
