I invited you over after school. We've been passing notes about hanging out and BDSM. I bet you've never tied up your balls before. That changes today! Today we're doing my favorite extracurricular. You will need a shoelace or ribbon to start. Follow my lead. We are going to tie up your balls so tight! I bet other boys are so jealous that you're hanging out with me. I bet they think you're getting laid. Nope, I'm tying up those virgin balls. You are going to hit your balls for me too! That's right, 50 firm slaps to your balls before I let you go home. If you don't do what I say, I'm telling the entire school that you have a small dick and that you came before I was undressed. Everyone will call you a loser. Haha, that's right, you'd rather slap your balls for me. Good slut. We're doing this every day until I graduate.
