Misono Mizuhara is a female employee at a lingerie company whose daily routine involves satisfying the sexual desires of her coworkers and executives with her J-cup breasts. As part of research for new lingerie designs, she licks and wets her own breasts with saliva, then allows them to be licked and sucked by male staff. Additionally, she participates in the development of nursing bras by performing handjob-style "nursing" sessions on employees' penises. Misono's breasts are considered a special asset for boosting employee morale and are a constant focus within the company.
