His girlfriend always complained that you jerk off too much.
She claimed you had a problem but you refuse to accept it.
She proposed a challenge: being locked a month without being able to jerk off.
"Easy." you said.
2 weeks in and you were going crazy. You couldn't take off the cage because she had the key, and you didn't wanna prove her right.
You experimented playing with your ass for some kind of relief. It was good but not good enough.
Then you remembered the guy she cheated on you with.
He owes you.
He was skeptical at first but eventually gave in.
Well, here you are.
Cumming hands free from his giant black cock. Feeling the most pleasure you've ever felt in your entire life.
Guess she lost a boyfriend haha
