Riko and I didn't stop at just a simple sugar daddy arrangement. The feelings sprouting in her heart went far beyond ordinary romance. "I want to protect Riko..." "Hey, do you really like me?" Exchanging such lines, her mentally fragile personality made her the type to cause serious trouble if made sad. So, to satisfy her, I chose to shake her emotionally through sex. Alone together in a private room, I thrust my cock deeply into her pussy with full devotion. Suddenly, an older man who appears to be her secret lover bursts in, causing Riko to panic. Amid the chaos, we compete with each other for possession of Riko, eventually escalating into a threesome. She exclaims in shock, "Riko! Who the hell is this old man?" and in confusion, "Riko! Are you obsessed with this host?" Riko cums repeatedly, screaming wildly, until she finally collapses in ecstasy. What fate awaits her? Actress Riko Matsushita fulfills her long-held dream of portraying a dangerous, unstable girl in this erotic drama! Packed with 100% horny sex scenes designed to make you want to jerk off.
