Tsubomi, in a morning rush, forgot her bra and ended up going to work without one. Due to the heat, she fanned her chest, accidentally exposing her nipples to her disliked boss, triggering his uncontrollable lust. Throughout work hours, she was constantly groped and subjected to nipple harassment. Using aphrodisiac oil, he made her experience her first nipple orgasm, training her with sex toys until she lost bladder control. During client entertainment, she was forced into a creampie threesome. Transformed into a woman highly sensitive in her nipples, she gradually succumbed to pleasure.
