A story about a married middle-aged teacher who succumbs to temptation when his student, who is also the student council president, provokes him by showing off his anus. Even though his wife is nearby, the student boldly shows off his asshole, and the teacher loses his senses and cums inside her again and again! The student, who discovered the pleasure of orgasming so hard that her sensitive, unshaved asshole twitches, started coming to his house almost every day... From then on, he would sneak away from his wife and lose himself in her small uterus, pounding it with his huge cock as much as he wanted...!
