The new bible for big-breasted maniacs, which covers the correct handling of boins in a fetish-packed course using Hiyori Koharu's I-cup and a practical version full of eroticism! First of all, basic paizuri. You can experience the elasticity scientifically and visually by using raw chin as well as dildo. And a test of rubbing, playing, and grabbing. Apply lotion and check elasticity more glossy. Poke violently with the last FUCK and enjoy the huge breasts that shake freely!
