[ADN-538] The story of incredibly wild sex with the older sister who barged into my house. Shiromine Miu

The protagonist meets Miu at a local park and notices that she is in trouble.

Despite not even knowing her name, he invites her to go to his house to stay for a while.

She quickly becomes clingy, and perhaps as a way to thank him or to escape her past, they engage in long sessions of affectionate sex.
