On a bed bathed in sunlight, two beautiful women lie side by side. Older sister Koharu offers her own breasts to her younger lover Mirai, who suckles eagerly at her lovely pink nipples. Koharu's erect nipples grow even more sensitive as she rolls Mirai's light brown areolas and nipples between her lips and tongue. They rub their legs against each other's nipples, building intense pleasure until both are driven to climax... Their passionate exchange unfolds like a dreamlike scene.
