I love ruining a male orgasm. Manipulating to the brink. Teasing until it's about to climax then ignoring it. The moment he's about to cum, when he needs attention the most, he is denied. The look in his eye is desperate. Pleading. It's hilarious. He needs to be jerked to enjoy his orgasm. Instead, I abandon his cock. I'll let his dick bob, dribbling cum. Nothing touching it but air. That's when I smile. I took his pleasure away, right when he would have enjoyed it most. How much can your dick take? And how little do you think I'll give? This is cum ruin!
