A hidden camera story set during a casual drinking party between a man and a woman. Ryouko is a charming, modest girl with an adorable smile. Though she claims to be inexperienced with sex, she starts climaxing intensely the moment penetration begins. Unaware of the hidden camera, she agrees to hang out with a guy she met through casual flirting and heads to his place for drinks. As they drink, their conversation grows increasingly intimate, with more and more physical contact. Once Ryouko gets completely drunk, she lets her bra slip, exposing her large breasts for him to lick and suck. Though she pretends to be shy, she's clearly overwhelmed with pleasure. After passionate deep kissing, he removes her bottomwear and fingers her pussy, making her thrash her legs as she orgasms hard and repeatedly. When she suggests taking a shower, they wash each other's bodies, leading naturally into cunnilingus. After receiving a blowjob, she slowly and carefully moves her mouth on his cock. Then, right in the bathroom, he enters her bareback. They passionately enjoy various positions, including missionary and standing doggy style. Moving into the bedroom, she rides him in cowgirl position, bouncing her big tits, before finishing in missionary with a creampie. In an unexpected twist, she flies into a rage upon realizing he came inside her without permission, slapping him hard across the face.
