Senior office lady Kotona exposes Mirei's oversized button nipples, pulling and pinching them. Mirei writhes in pleasure as her nipples stretch to twice their length, the impressive deformation from twisting and stretching leaving a strong impression. Licked, sucked, and rolled by Kotona's lewd tongue, Mirei sinks deeper into a swamp of pleasure. Unable to resist, she latches onto Kotona's nipples, and the two reach nipple ecstasy through mutual nipple licking.
