Under the pretense of it being a "squirting" project, Hikari is forced to drink a lot of water before filming. However, the water contains an aphrodisiac! As filming progresses while using the aphrodisiac in lotion, her sensitivity increases and she trembles in convulsions! As the aphrodisiac continues to be added, her pussy becomes stupid and squirts a lot! She completely falls into the trap of being a bitch who happily sucks dick.
