Tsubomi oversleeps, rushes to work without a bra, and accidentally lets her hated boss glimpse her nipples through her clothes. He becomes obsessed and starts fondling them throughout the workday. Aphrodisiac oil gives her a first nipple orgasm, toys train her until she urinates, and entertaining a client ends in a threesome with creampies. Constant nipple harassment transforms her into a woman who orgasms from nipple play alone.
