Miss Katherine
Mmm, I do love a nice hard cock. Why don't you play with your balls a little while I lay down the rules?
Number One: You have to do exactly what I tell you. Disobeying me means losing your chance to a full orgasm.
Number Two: DO NOT CUM, unless I tell you to. If you feel yourself getting close, stop stroking and squeeze your balls until your dick goes soft, then start the whole page over.
Number Three: If you can't help it and you do cum before I tell you, follow these steps.
1. Slap your balls until they're bright red and you can barely stand up.
2. Squeeze them until you feel it in your stomach, then squeeze harder. Hold this for as long as you can.
3. Rest your balls on the toilet seat, then let the lid drop on them. Five times.
After you have completed these steps you may restart the tease.
Note that these rules are allowed to be ignored only if I tell you otherwise.
Make sure your cock is nice and hard before you continue.
