The Seventeen Alpha Onahole is the latest in a bestselling series of masturbators by industry leaders Toy's Heart. The internal design of the hole contains an innovative "pipe gimmick" section that replicates the feel of a uterus. The rest of the snug tunnel is a feast for the cock as you slide through the wet groove at the opening, where lube accumulates, and then across the hugging ribs and finally into the end chamber with its host of bumps and nubs that tickle the glans upon every thrust.
