Cute short-haired Riku hides a surprisingly lustful and horny side beneath her innocent appearance. In her school uniform, she desperately sucks on a big cock, licking the shaft and balls with fervor, her face transforming into a slutty, aroused expression. While being watched by her badminton club coach during practice, he suddenly touches her nipples and asks, "Do you really like sex?" Riku honestly replies, "I want to be fucked." As a result, she's invited by the coach after school, where she eagerly takes his cock deep into her mouth and allows him to thrust all the way into her tight, narrow pussy. She starts moving her hips on her own, craving deeper penetration. Finally, as she pleads, "Cum inside my mouth," she climaxes with loud, wet sounds, completely lost in pleasure.
