After giving birth in her mid-thirties, Reiko Manda's body has grown increasingly sensitive, her libido intensifying each day. When alone, her arousal builds stronger than ever, her face flushing deeply red. Every time her lover arrives, her heart races uncontrollably, her desires mounting rapidly. When she's alone with her boyfriend, she becomes even more lustful, carefully selecting more elaborate lingerie, and on special occasions, wearing outrageously sexy underwear, fully ready and eager. She forgets about her husband and child, diving headfirst into pleasure as her true self. Screaming "No~!" and "It's embarrassing~!", she gradually transforms into an insatiable woman, her pussy completely wrecked from the start. Moaning through repeated orgasms, her overwhelming passion threatens to consume everything. Men can't help but lose control, utterly captivated by the horny, uninhibited Reiko.
