Immersed in swimming since childhood, she once aimed for the Olympics. After a setback due to injury, she now works as a swimming school teacher, working late every day. Overtime, overtime, overtime. Rinon Sono is a pure older sister who takes everything seriously. When called out after work and invited on a date... the door to her long-suppressed sexual desire swung wide open! A kiss upon arrival, a kiss whenever their eyes met during conversation, a kiss at every red light while driving. Just kiss after kiss after kiss. Even during their date at a shop, she'd tease his nipples while playing games or stroke his cock—even though they were in public. Eventually, unable to hold back, they had sex while trying to keep their voices down, surely getting caught. On the way to the hotel, she gave him a taste of his cock with a blowjob in the car. She was a total sex monster. Once they arrived at the hotel, they coupled greedily, pounding away until morning. Forgetting the meaning of a dry pussy, they just kept fucking. Sex with an athlete after exercise is ferocious, animalistic, and incredibly erotic.
