Bullied young boy Shotaro was crying in his bedroom after another awful day.
All of a sudden, a gorgeous woman with massive breasts appeared!
She immediately decided Shotaro is her master, and she shall be his servant....
But she's easily lovesick and a masochist pervert as well!

Train, school, park, myriad locations and lurid fornications! She's the servant, but she demands sex! How's a boy to cope!?
