The Timid Me Got Pity from My Schoolgirl Sister Who Promised Just Rubbing But We Got Too Turned On, Her Pussy Got So Wet, Then Slipped In Raw! "Huh!? It's Inside?" But Couldn't Stop and Came Inside Her! Rin Miyazaki

Returning home from club activities, Rin falls asleep in the living room still wearing her uniform. Her brother, noticing her exposed underwear, becomes instantly aroused by her vulnerable state. Unable to resist, he begins masturbating while sniffing her gym clothes. When Rin wakes up and realizes what’s happening, she’s shocked and disgusted—but she can’t bring herself to truly hate her brother. To ease the awkwardness, she offers to help him out. Still, he can’t reach climax. He asks her to change into her gym uniform, but even that isn’t enough. Finally, Rin suggests, “Onii-chan, we’re siblings, so we can’t actually have sex—but what if we just rub together? You can cum that way. Let’s do sumata.”
