NHDTB-366 At a mixed-bath hot spring, she felt her nipples harden through the towel after finishing breastfeeding, making her sensitive wife feel aroused.

A mother who has finally found some peace in child-rearing relaxes at a hot spring inn. As she approaches in the mixed-gender bath, she hides behind a rock and, through her thin towel, fondles her nipples! Her nipples, softened from being sucked on too much by her child like cotton candy… are pinched, sucked, and obscenely enlarged!! The sensation of guilt as they harden to the point of popping is exhilarating! She drowns in forbidden pleasure and indulges in an affair!
