Unfortunately for that piece of fabric, Serene was one of Seth's weak spots and he wasn't able to hold himself anymore, kind of ripping some pieces of her dress and directly exposing her underwear.
Serene and Seth had a very mild and calm lovemaking session on her first experience time. However, he was now going to show her how things were on the other side of the coin.
Serene wasn't expecting he would do something like that and got very surprised, but even though she would have to give an excuse to the person that lent her that robe later, she felt that what he had done was pretty exciting.
"Serene, every time that I look at you, I can't control myself."
"You don't need to control yourself, dummy."
Seth smiled and said: "Hehehe... You said it yourself."
"Ah!"
