すずり先生と26個のエッチなおっぱい

The protagonist, Saiki Shizuya, got super lucky when his crush, teacher Nagisa Suzuri, became the student council advisor after their homeroom teacher went on maternity leave. One day, alone with her in the council room, things got heated - she hugged him, he clumsily tried to go further but failed (messed up her clothes, came too soon from her handjob) and got caught by his senpai, Asakura Miki. Instead of getting in trouble, Suzuri just complained about how bad he was at sex. Shockingly, Asakura proposed teaming up with Suzuri to "make him a proper man" by secretly renting him out as a host to other female teachers who like him. Their payment? More power and influence in school. They were now scheming like villains, planning who to "sell" his virginity to and taking photos. Yet, despite ending up becoming Suzuri's servant and rental host, Shizuya was still completely mesmerized by her cool profile.
