I'm Sorry, Onii-chan, I Love You.

An older brother in university and a blood-related younger sister who's just a bit younger.

The brother knew about his little sister's feelings for him, and yet he kept lying to himself. That is, until he sees his sister masturbate in front of him and their quick intimacy begins!

Please enjoy this story about a brother and sister who both know they shouldn't be doing this, yet continue to express their feelings for one another♪
