While my sister was away at home, she rolled over without her permission and creampied her with her handsome boyfriend for three days.

My girlfriend, who is living with me, ends up leaving my house on a business trip to the countryside. I don't know if she knows about her absence, but my younger sister Mitsuki crouches into our house. A gal who doesn't look like her at all. A record of her giving in to the temptation of her younger sister and having creampied her so much that she thought she would have been pregnant.
