i'm shiraishi kana, a bitch sister who distorts your friendship and sexual intercourse.

A college student nerdy man who started living alone on the occasion of his enrollment. My sister, envious of her brother, often went in and out of her brother's room. One day, she negotiated to rent her brother's room as a place to have sex with Sefre, but she was refused because her friend came. The troubled sister was to carry out the super evil and rude idea that came up. Sad woke up as he was driving his brother into the heart. He laughs at his brother's appearance, who was destroyed and made mazo.
