A man who secretly lives a two-pronged life and enjoys his days. One day, when she went to her house, it was discovered that the two were sisters. Normally, I'd be in a cold sweat and it would be hard to escape, but I came up with the idea of enjoying two people at the same time. Realize a dream-like time with a variable speed 3P where you have sex with your sister in one room and sex with your sister in the next room.
