Back in college I was friends with this guy, and we were both in the same class. He was struggling with the class but it was his last semester and if he failed he’d be screwed. So I made a deal with him. If he passed the class I’d give him the best blowjob he’d ever get in his entire life. I wasn’t really attracted to him, he was a little heavier than I would normally like, and his face was pretty average. He was smart and funny and I liked being his friend though so I had no problem helping him.
He didn’t believe me at first, but he made an effort anyway. Everytime he got a good mark on a paper, or a quiz, I would reward him. I’d show him my tits, or I’d rub his cock through his pants. He was convinced after the first time I grabbed his dick. Soon enough at the end of the semester he passed with a C. As soon as we got our grades I showed up to his dorm in a tight little crop top and shorts that barely covered my ass. I told his roommate to get out, which he did, while giving his buddy a thumbs up which I thought was hilarious.
