The Pussy Snorkel
The Pussy Snorkel allows a man to continue breathing while performing oral sex on a woman in a spa, bathtub or even a bowl of green Jell-O. Insert the breathing apparatus into your nostrils, rub the clitoral stimulator against your favorite coral reef and start with the tongue action. With the Pussy Snorkel, any man can be a dive master.
Note: If you use it lying down, make sure you turn your hips to avoid a case of the bends.
