Honoka, a rigidly serious teacher, is horrified by the trash-filled home she visits for a student's family meeting. She drains her own bottle of water to calm down, unaware that someone has spiked it with an aphrodisiac. Her sensitivity surges, her pussy floods, and both her body and mind melt into intoxicated pleasure. The once-prudish teacher becomes delirious and begs for more as three generations of the family force themselves on her.
