So back in the day, my wife had a few guys off and on that she would see with one of them being relatively consistent, unless he was cheating on her, then she would retaliate and do the same. It was a toxic relationship, but it made for some great entanglements/stories.

One year for his birthday, she decided she was going to get him some weed, but she didn't have a job as she was freshly out of highschool and on her way to college.

One of the guys she would routinely have revenge sex with, was also a dealer. She decided to ask him for the bag. Without any money, he said she had to pay with her ass. A blow job for the weed, and if she wants them rolled into joints, he also gets to bend her over the couch and cum on her tits.

Needless to say, she got her boyfriend the gift, and it wasn't the last time time that exchange was done.
