Kenzen Bishoujo wa Shigokitai!!

Kenzen Bishoujo wa Shigokitai!! summary: Shinichi Hosoi, a rather asocial guy, has just started his dazzling first year of high school. He had a horrible time in middle school because of how he joined the sports club in order to be popular with girls, so he was determined to go out with a bookworm-type of girl in high school! But the absolutely gorgeous upperclassmen who come to him end up inviting him to... the high school weightlifting club?! The club is like a grove filled with nothing but tough, warrior-like girls... And to top it all off, every one of them is super erotic and love teaching him in ways where they can touch him as much as possible! Will this boy be able to keep his cool, even while being surrounded by beautiful muscle-head girls without any other guys in sight?! Source: Takeshobo
