A glamorous J-cup office worker discovers that the breast harassment from the boss she despises feels exactly right. His persistent daily fondling trains her into an oversensitive masochist who climaxes almost instantly despite begging him to stop. Her nipples harden and she begins craving more, gradually surrendering to the pleasure. During a sexual-entertainment scheme arranged by the sleazy boss, she is groped into repeated orgasms and coerced into taking his creampie until her reason collapses.
