This role-play is performed by adults. It's been a long time since I've been with my wife, and I'm in the prime of my life. So I disguised myself as a business trip, stayed at a hotel, and secretly called a delivery health service... Surprisingly, my sister-in-law Lala came! When I was in a panic, she said, ``You're not acting like a big sister, right?'' and even let me do the actual thing, which I didn't approve of...! Lala-chan, who can't forget the orgasmic sex that was so perfect for her, steals her wife's attention even at home and boldly asks for her... If this happens, you have no choice but to take the risk and fuck it to the fullest!
