Kathlin Bonner, the insatiable exhibitionist, is back with another self-inflicted punishment. This time, she's focusing on her sensitive, bountiful breasts. She teases her nipples to rock-hard peaks, then proceeds to deliver a relentless barrage of slaps, twists, and pulls. Her moans fill the room as she works herself into a frenzy, her body writhing with a mix of pain and pleasure. The camera captures every moment of her self-degradation, zooming in on the reddening, swelling skin, and her glistening, desperate pussy.
