The girls were looking for fun, riding in the car. Sometimes they got themselves excited. Apparently they wanted a new sensation, so they offered a threesome to a strange young, handsome guy. After some persuasion and conversation, he agreed and went straight to work. The girls hooked up with him, gave him blowjobs, rolling on top, while two were fucking, the third fondled the couple.
Turns out you can fuck a girl this juicy on the street just like that. She seemed a little too cultured to me at first, but then she quickly decided to fuck with a guy and everything went great.
