Tsunu gently caresses Rion's breasts, slowly pulling aside her bra to reveal nipples swollen deep red and visibly engorged, twitching with arousal. Rolling them softly between her fingers, she then laps at them with her tongue, causing the nipples to grow even fuller. The intimate, erotic licking between two girls intensifies their mutual excitement, hearts racing as they explore each other. As their bodies touch and respond, this becomes a uniquely profound and sensual experience.
