Masochist Sister’s Private Lessons – My Sex Tutor Big Brother

Synopsis

Akitoshi Arikawa is living his university life away from home when his step-sister Midori asks him for a favor. She wants him to tutor her younger step-sister Ichigo, whose grades at school are poor, to help her get into a good school. Since both sisters have moved out due to work and school commitments and live nearby, Akitoshi agrees to help without hesitation, thinking it would be a good opportunity to reconnect with Ichigo.

However, Ichigo proves to be far worse at studying than expected. Instead of focusing on her studies, she becomes fascinated by the adult magazines hidden in Akitoshi’s room. “I’d rather learn about sex stuff than take stupid tests, big brother,” she says seductively, gradually wearing down his resolve.

Unable to resist his own desires, Akitoshi proposes a new condition: if Ichigo studies hard and does well on her exams, she’ll receive sexual rewards. With this arrangement, Ichigo’s exam preparations finally begin in earnest.
