Koi mo H mo Obenkyou mo, Omakase! Oneechan-bu

Kyousuke is on the verge of failing his school year. With poor grades and a crucial exam at the end of the month, he faces the real possibility of repeating the year. His older sisters step in to help, forming the "Oneechan Club" with the sole purpose of supporting his studies.

However, Kyousuke soon realizes that academic help alone isn't enough to motivate him. He needs a stronger incentive, one that his sisters are all too willing to provide. Their study sessions quickly take a turn into more intimate territory, blending education with sexual motivation.
