Karin no Archive #20236

Karin-chan is a popular girl at school. She's got the perfect skin for suntanning.
She's also a blend of bad habits: reckless, talks like a boy, kind of a crybaby.

Her big stepbrother has developed a fixation. Karin-chan's style makes his heart pound.
He finally tells her. She naively responds. They begin to date.

It starts with a kiss. Big brother is bad at kissing, she thinks.
Big brother also thinks something: that his little sister is way too good at kissing.
He thought she was innocent, but she knows her way around a guy!
