Hehe.” Yu Chuan: “No need, thanks.” The little demon burst into tears. Yu Chuan admitted the little demon was adorable, but he never expected this: The little demon really could transform into a 1.9-meter-tall silver-haired beauty, and would even crouch in a corner to sneakily slap the giant dog’s broad muzzle... *The seme can take all sorts of forms to cling to his darling *Both are sexually inexperienced | The seme starts out cute and gets fierce later |
