Tsundero Series – Episode 4 (ES)

Tsundero Series #4 spotlights childhood friend Saya, tormented by her enormous, swaying breasts and long, ultra-sensitive nipples that draw unwanted attention wherever she goes. Though she acts tsun toward Daisuke—the boy she's loved since childhood—his lingering stares on her chest secretly thrill her. One night, alone in the school pool for extra swim practice, Saya gives in to her desires and masturbates while moaning Daisuke's name. Her breasts swell even more dramatically from arousal just as Daisuke arrives unexpectedly. Unable to hold back, he approaches and begins lavishing her complex body parts with hands-on attention: squeezing, sucking, and teasing her massive tits and elongated nipples until she's trembling with pleasure. Saya's initial embarrassment melts into eager reciprocation as she pulls him into the water for their first shared sexual experience. The wet, slippery pool setting amplifies every sensation—passionate kissing, intense breast play, paizuri, and deep penetration—culminating in a heartfelt confession of mutual love amid powerful orgasms and creampie climax. This OVA beautifully captures the shift from insecurity to acceptance, delivering one of the series' most emotionally satisfying and visually explosive h-scenes yet.
