Shiho Egami, a busty office worker, indulges in solo nipple masturbation during overtime, fantasizing about her boss. She shamelessly exposes her G-cup breasts, licking and dripping saliva on her rock-hard nipples. This private moment is accidentally discovered by her colleague, An Mizutani, who threatens to share the footage company-wide unless Shiho performs live. Under duress, Shiho starts her solo act, which soon escalates as An joins in, turning to mutual nipple licking. The two engage in a steamy nipple-focused 69 on the office desk, culminating in a shared orgasm.
