That JAV

My live-in girlfriend went on a family trip for four days. As I waited alone for her return, a sudden visitor arrived at my house.... It was her sister, Saeko-san, who was unable to go on the trip due to work. Why...why...? Saeko-san seduced me while I was puzzled.... This is a record of the four days she was away on a family trip, and how I fucked and fucked her.
