Gas Mask

A delightful combination of two well known activities; Arabian Goggles & The Gunner. This is achieved by gently placing the gonads on the respective eye sockets of the eagerly waiting recipient while simultaneously lowering the anus and spreding the corn hole wide over the nostrils of your partner. The gas mask will provide you with endless hours of pleasure and entertainment.
