"You have to wash it properly!" My older sister came into the bathroom and peeled off the skin of my phimosis Ji ○ Po and washed it. No matter how much siblings are stimulated directly like this, they will get an erection. Then, the sister's eyes, which had been full of affection until a while ago, changed to the erotic eyes of a nymphomaniac. The bathroom becomes a naughty atmosphere at once! Even though we thought it was no good, we were dominated by that lewd atmosphere, and we did a little naughty thing on the spot, and then returned to the room and developed into full-fledged sex!
