We're going to play a fast paced card game today. The rules are simple. You will begin by stroking your cock. If I draw a card with black numbers, you will continue stroking and PUNCH your balls. The amount of punches depends on the number I've drawn. If I draw a red card, you will SLAP your cock, and stop stroking for the duration of the slaps. I won't give you much time to recover between cards, so you will probably be in agony the entire time. Just so you know, you aren't guaranteed an orgasm at the end.
