Climax with a rush of goodness! Doc Johnsons Squirty Peter Dinger has two ribs below the head, a sleek shaft and a cluster of bumps near the base of the shaft to provide clitoral stimulation. Prepare the squirt action by filling the attached bulb with liquid or lubricant. Then squeeze the hand pump, and the Dinger ejaculates. A flared base makes Dinger compatible with a strap-on harness for partner play. It is made from phthalate-free body safe material, which includes Doc's antibacterial Sil-A-Gel formula and is Proudly Made in America.
