KTRA-441 Megu Mio

A serious honor student sister “Megu”. When I was studying in my room, my brother came in and gave me a massage, but his hands became more and more naughty and my 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!
