Monster Hole series has added another product to their dual-layer mastubator, the Monster Kakusei. It is the fifth masturbator in the Monster Hole series. This time they have made the item even more "Monsterific". The outside appearance looks more interesting with veins, bumps, and wrinkles, while the inside has more flesh like bumps, ribs, and winding path for one unique experience. The dual-layer design adds stimulation to the hole while still having the outside feel soft to the touch. Due to the dual-layer design, Monster Kakusei is unable to flip inside out. Awaken your sexual pleasure with Magic Eyes' Monster Kakusei!
