BF567 — I Spent My Girlfriend’s Four-Day Family Trip Fucking and Creampieing Her Older Sister

My live-in girlfriend leaves on a four-day family trip, and while I wait alone for her return, an unexpected visitor arrives: her older sister Saeko, who could not join the trip because of work. Ignoring my confusion, Saeko begins seducing me. This is the record of how we lost ourselves in sex and repeated creampies throughout the four days my girlfriend was away.
