So it was her 21st birthday. And we had gone out with a few friends and had anice dinner. We all stay after dinner a bit a dank. Alot! Well it was around midnight and we where wanting to go. As soon as we got on the highway, she got on her knees in the seat and bent over undoing my pants and pulls out my cock. She is cock hungry at this point. She just starts sucking. She has never want me to cum in her mouth. After a 30 min ride we are about 5 minutes away from our house and i cum. Don't tell her im gonna cum i just do it. Maybe she will be drunk enough to swallow. My first thoughts. But I tell her I'm about to cum and she starts going like thats exactly what she wanted is my cum and she wants it now. After I cum and she gets allof it i think she is gonna swallow it all, but no.. she jumps up and rolls her window down and spits it out side. Me being drink didnt think nothing of it. A couple of days gose by and im walking down that side of my car and notice something on rhe side of it. My cum was all down the side of my car.. i left it there for another day before wasing it off.
