Big-tits lactation actress Narasawa Hinami is mercilessly teased to prevent her from producing milk. It begins with bareback sex, stimulating her erogenous zones, and she softly pleads, "It feels so good... I can feel breast milk building up in my glands." Responding to her reaction, two male performers team up to intensify the torment, using feather touches and vibrators to relentlessly tease her nipples and areolas. Each time, she gasps, "I'm going to leak milk...!" only to be brought to the brink and denied orgasm repeatedly. Finally, all restraint is released, culminating in an intense threesome where thick, milky breast milk sprays wildly during passionate sex.
