This role-play is performed by adults. After seeing off his wife who went on a trip, Kenji felt lonely because the house was too big for just one person. At that time, my wife's older sister, Minami, suddenly appeared. She was briefly happy to be able to escape from her loneliness, but Minami, who has been touching her body intensely on a regular basis, presses her breasts with an innocent look on her face. She has fluffy big breasts that my wife doesn't have, and her body is soft no matter where you rub them. This cannot be allowed. Even though I know this, I still get excited when my cock swells up at the attractive body in front of me...
