He's Raging Stallion's Man Of The Year... and one look at his face, his body and his cock was all the judges needed. Now all 10.5 inches of this gorgeous Argentinean hunk can be yours nightly as we present the D.O. Signature piece. Molded from D.O. himself, it's absolutely real in look and feel, capturing every twist and turn of his massive shaft. And like all our premium-quality Supercocks, it features a strong suction cup base for hand-free play on just about any flat surface. D.O. has a suction cup with a neck diameter of 1.75”. Cup diameter is 3”. A good o-ring size on a harness would be 1.75-2”.
