Hino Iori thought that being punched in the stomach or choked was just a normal part of foreplay, since all her past boyfriends were sadistic. When someone jokingly suggested, "How about you try dominating a guy for once?" she got excited—and so we prepared a perfectly sturdy friend with a strong masochistic side. His manhood is incredibly powerful, codenamed "Wanwan," who might be as strong as a mastiff. Facing Wanwan, Hino can't contain her excitement. She starts by slapping him to test his limits—spanking his thighs, smacking his face. Though used to receiving, she's new to dominating, starting hesitantly. But seeing Wanwan's pleasure, she grows bolder and more aggressive. Having never experienced meticulous foreplay before, Hino is overwhelmed by Wanwan's persistent, delicate stimulation. Her shy, petite breasts perk up, nipples hardening and twitching. "Bite it a little…" Wanwan instructs softly—a perfect display of his true masochistic nature. When checked, Hino's panties are soaked. She lies Wanwan down and grinds her wet pussy onto his face, licking and teasing. "It's like I'm being sucked and devoured…" she murmurs, realizing how good it feels to be consumed. Hino cums from face-sitting and oral licking. Even after climax, she doesn't stop—she smothers Wanwan's nose and mouth, disciplining him. Even near suffocation, his tongue won't stop, so she straddles him and slaps him repeatedly—punishment? Or reward? To discipline the horny Wanwan, she grinds against him while still wearing her panties. Then she yanks them off and delivers harsh slaps to his rock-hard cock—another scolding that clearly isn't working! Gentle owner Hino tries hard to take Wanwan's oversized cock into her mouth. It doesn't fully fit, but she licks it carefully, looking adorable. Still craving more, she mounts him and takes it deep. It somehow fits into her small frame. It looks tight… When he pounds her from behind, she seems overwhelmed, almost breaking—but judging by her voice and expression, she's feeling incredible. Since Wanwan is a true masochist, she makes him reach climax by rubbing his own cock while she toys with her nipples—a deeply humiliating finish. Hino is so sweet and kind after all. No wonder he cums so powerfully!
