a fierce battle of muscular penises erupts between Atushi and Iori!?

What on earth will happen this spring!?


Ryota Hibiki【Top】

「I’ve found a new dream」

A ronin student who re-challenged himself with the university entrance exams. As a result of finding a goal and studying seriously, he successfully passed the university exams. He will start attending university from April.

Drawing from his experiences in “Gachi-Natsu,” he has grown emotionally and has become more mature in his way of thinking compared to before. However, he still tends to rush into things due to his youth.

He has been dating Kenzaki Atushi since “Gachi-Natsu.” Ryota’s sexual desire knows no bounds, and in addition to his huge penis and incredible stamina, he has also acquired techniques that often overwhelm Atushi.

Dreams can also be a curse, you know

Hibiki Ryota’s tutor and boyfriend. After “Gachi-Natsu,” he taught Ryota’s studies again as his tutor and successfully helped him pass the university entrance exams.

Upon seeing Toramaru Iori, who reunited with Ryota, he quickly realized that “Iori has feelings for Ryota.” With this understanding, he proposes a perverted penis battle to Iori.

He succeeded in raising Ryota to be a splendid top, but the results were beyond his expectations. Because of this, he finds himself moaning constantly every time they have sex, letting out cries of joyful agony.

Ryota, you’re going to play baseball again, right?

Hibiki Ryota’s best friend from the same high school. He used to be active in the baseball club together with Ryota and was a star player as the ace. In university, he continues to excel as both a pitcher and a batter.

He is a well-rounded sportsman who is also good at studying. He never fails to do training such as weight lifting, and is sometimes talked about as a promising player for the future.

He is not a virgin and has plenty of experience dating women. Although he is popular due to his refreshing looks and his performance in baseball, his favorite fantasy to masturbate to is actually Ryota. He has no knowledge of erotic activities between men and has never experienced it.
