KTRA-441 Megu Mio

A serious honor student sister "Megu". When she was studying in her room, her older brother came in and gave her a massage, but her hands became more and more naughty and her breasts were fir. Zero experience with men. On top of that, "Megu", who is weak against pushing, decides to have sex with her brother as it is! Even if I can study, I'm not good at naughty things. Even though I was nervous, I decided to ask my brother to teach me all the pleasant things!
