Rui Mizuki is a pale-skinned I-cup beauty who casually exposes her breasts while chatting at an inn. Unable to resist her bursting chest and round ass, the man starts teasing her outdoors and learns that she loves big cocks. In the hot spring she shows off expert blowjob and titjob skills before taking a load across her ass. Their open-air fuck unleashes her full sex drive, and although she worries about being seen, she moans loudly and cums again and again.
