Misuzu, her body slick with sweat and steam, can't help but touch herself, her fingers dancing over her clit, as Wolf watches, his cock twitching. She turns to him, her eyes filled with a mix of shame and hunger. "I can't stop," she confesses, her voice barely a whisper. Wolf, his resolve crumbling, palms her tits, squeezing the firm flesh. "Neither can I," he admits, his hands wandering down her body, finding her wet pussy. They kiss, a messy, desperate meeting of tongues, as they fuck, their bodies slapping together, Misuzu's cries of pleasure echoing through the onsen, her orgasm ripping through her, leaving her a quivering mess in her brother's arms.
