While his girlfriend was away, he met his ex-girlfriend, Shioriho, for the first time in a long time. She has grown up a lot since then, but her charm hasn't changed. He was tempted and introduced Shioriho to his house and had sex with her. When he took off her clothes, he found that her breasts were much bigger than they were back then. He was so engrossed in touching his ex-girlfriend's mature body that he had sex with her many times.
