After misusing neighborhood association funds, chairwoman Azusa asks the accountant to help conceal the embezzlement. Instead, he threatens to expose her unless she obeys. He forcibly gropes her 98 cm G-cup breasts and relentlessly tortures her sensitive nipples, training them into an even weaker spot. She resists at first, but the overwhelming pleasure destroys her self-control. The proud married woman is gradually broken into a shared toy for the men in a depraved training drama of forced orgasms and nipple climax.
