Available as an ass, mouth or vagina, the Sex Donut is a cock ring made of a skin-like material (they call it "Passion Skin") and is designed to be fitted to the base of a penis enlargement pump. That way, see, you can create an airtight seal to maximize that penis-pumpin' power. Now all you need is the penis pump (and somehow we have a feeling Topco's got 'em).
