Alone in the apartment, our protagonist's eyes fall on his roommate's heels, a kinky idea sparking. He pisses into her shoes, the warm, yellow liquid filling them, the smell intense. His cock hardens at the sight, and he jerks off, his hand coated in his own piss and pre-cum. He cums hard, his load mixing with his urine, creating a filthy, intoxicating mess. He picks up her shoe, sniffing and tasting his naughty deed, his heart racing with excitement and shame.
