[VENX-279] - I'm a low-spec virgin in a ronin life, and my brother's wife, who is highly educated and beautiful, gives me a vaginal shot lecture.

Kenta of Ronin who was taught by his sister-in-law from a famous university how to prepare for the exam. I was relieved that I was safe with this, but for Kenta, who had devoted his youth to studying, his sister-in-law's beauty was too stimulating. A neat profile smiling next to her, a soft body that sticks to her, and a cleavage that peeks out. My sister-in-law, who noticed Kenta, who was full of suppressing instead of studying, approached me and said, "I'll teach you this before studying." - The first experience of a dream where a beautiful and highly educated sister-in-law with outstanding style will give you a hand-to-hand lecture starts!
