Gachimuchi de Dosukebe na Kateikyoushi no Onii-san to Sugosu Haru
ガチムチでドスケベな家庭教師のお兄さんと過ごす春
As the seasons changed and the time for cherry blossoms to bloom drew near.
Hibiki Ryouta, who had found a new dream and decided to re-challenge himself with the university entrance exams, and Kenzaki Atsushi, who became his tutor and boyfriend to support him.
Ryouta, who successfully passed the university exams, is given a tour of the university by Atsushi during the spring break. At that time, Ryouta coincidentally reunites with his high school best friend, Toramaru Iori. The two catch up on nostalgic topics such as memories from their time in the baseball club and begin to reconnect.
However! Iori turns out to be a perverted guy who has been fervently masturbating to Ryouta as his fantasy! On top of that, unbeknownst to Ryouta, a fierce battle of muscular penises erupts between Atsushi and Iori!?
