The Grandfather Clock, also referred to as 'the Grandfather's Cock, is an intricate sexual act in which two men of roughly the same height suspend a woman of smaller stature upside down by her her ankles, swinging her back and forth onto each others erections like an erotic pendulum; the flesh hand of the world famous Grandfather Clock. With each 'swing of the clock', the woman of interest is penetrated from both the front and behind (commonly mistaken for a war on two fronts), alternating holes with each pleasurable sway. The partners in crime swinging the woman to and fro are each assigned a specific hole for their genitals to call home, depending on the directions of their erections, of course. The irony of this sexual act is that the participants will be so invested in reaching such a chronological level of ecstasy that their perception of time will fleet, and when they've finally finished, they'll realize that what felt like minutes of sensual fun was actually hours of tireless thrusting. The grandfather clock can make the best of the times out of the worst of times, but if executed improperly, it can make the best of times into an embarrassing trip to the emergency room (take it from me; I didn't know the penis could sprain until I fell victim to the grandfather clock's sensual wrath). While the clean up may be a disaster, it will have been well worth it afterwards; the benefits will come the second you do.
