Tsundero Series – Episode 3 (RAW)

In Tsundero Series #3, private tutor Yousuke arrives at the home of distant relative Yuna, a busty, little-sister-like high-school girl with an angelic face and a body built for sin. Despite his preference for smaller chests, Yuna's overflowing cleavage and playful teasing quickly challenge his self-control. During study breaks, she "accidentally" presses her massive breasts against him, whispers naughty encouragements, and poses provocatively in her uniform—transforming the strict tutoring session into a slow-burn seduction. Yousuke fights to maintain professionalism, but Yuna's pure yet succubus-like charm proves irresistible. When the tension finally snaps, their first sexual encounter erupts into a deeply affectionate, high-intensity lovemaking scene: tender kisses evolve into passionate caresses, oral play, and fervent intercourse that highlights her giant breasts bouncing with every thrust. Yuna remains emotionally innocent and loving throughout, her "dere" side shining through even in the most explicit moments. The episode masterfully captures the contrast between her lewd body and pure heart, delivering one of the series' most emotionally charged and visually stunning sex scenes yet. This OVA continues the tsundere theme with a sweet, big-sister-teasing twist.
