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

Kenta, a student who is a student at a recital, is asked to thoroughly teach her sister-in-law, who graduated from a famous university, how to prepare for the entrance exam. I was relieved that this was safe, but for Kenta, who has dedicated his youth to studying, the beauty of his sister-in-law was too stimulating. Her neat profile smiles next to her, her soft body that she holds close to, and her cleavage that she can see. Not only does it take for her to study, but to reduce her arousal, her sister-in-law notices Kenta, who is so busy with her, and she asks him to teach me this before studying... Our first dream experience begins when a beautiful, highly educated sister-in-law gives us a step-by-step lesson!
