Kousuke and Aizawa have been friends since childhood. When he meets Aizawa for the first time in several years, who has moved to Tokyo after graduation, he is surprised to find that he has been reborn from a man to a woman. Sara, who confessed that she had liked Kousuke for a long time, shows off his cock in the toilet and forces him to suck his erect cock. Even though Kosuke doesn't like it, he gets an erection and is sucked further.
