In a cramped room, Yuria Kano mistakenly sucks Wolf Tanaka's cock, thinking it's her boyfriend. She freezes, seeing Wolf's pleasure, then gives in, tasting his pre-cum. Wolf's thick cock fills her mouth as she struggles to take him in. He grabs her hair, guiding her, while she fights her taboo lust. "Fuck, sis, you're a great cocksucker," he grunts. Yuria gags, but the taboo thrill pushes her on. Wolf's hot cum fills her mouth, and she swallows, feeling filthy yet satisfied.
