Senior office worker Kotona exposes Mirei's large button nipples, pulling and pinching them until they stretch to twice their length. Twisting, tugging, and reshaping them leaves Mirei helplessly aroused. Kotona then rolls, sucks, and licks them with her broad tongue, drawing Mirei deeper into pleasure. Unable to resist, Mirei sucks Kotona's nipples in return until both women reach nipple-only ecstasy together.
