When you're ready for the big time, step up to this huge inflatable dildo with a max size of 14" in length and 4" in width (now that's plenty to take in). It's a heavy-duty dildo made of top-quality inflatable rubber. The dildo also has an internal sturdy core for ease of penetration and use. The penis is well-detailed, even showing veins and contour. You pump it up using a bulb with a reverse valve.
