NPH-107 - Received sex education from a friend's mother / Miku Aunt's adult body, Ishida Miku

When I returned home, my mother's friend was visiting and drinking with my mother. I was taking off my clothes to take a bath when my aunt invited me, saying, "Would you like to take a bath with your aunt?" and my heart raced. My mother passed out drunk and laid down on a futon, and my aunt hugged me from behind and gripped my penis. She saw my underwear peeking and a glimpse of my chest, and it was obvious I was aroused. "Young people are different after all~" It was hard to hold back a scream while my aunt sucked my penis next to my sleeping mother. She showed me her body in my room and taught me a lot about how to have sex.
