I'm a virgin and I'm a high-educated, beautiful, high-spec wife who gives me a creampie lecture at me, a super lucky first time sex

Ryo, a student who is aiming to pass the entrance exams to a difficult school this year, is taught how to study by his highly educated brother-in-law Mei. He was alone with Takane Hana, whom he thought would be out of reach. Her big breasts can be seen even through her clothes, her soft body, and her wonderful scent wafts out... All of these things stimulated Ryo's desires, but they were unable to concentrate on his studies. With such concerns about Ryo, Mei suggests that she take the first move... A dream virgin graduation ceremony where a beautiful, talented, highly spec beauty who you thought would never fit in will teach you how to take a step-by-step sex!
