The Batcave is the secret headquarters of fictional DC Comics' superhero Batman, (the dual identity of millionaire playboy Bruce Wayne), consisting of a series of subterranean caves beneath his residence, Wayne Manor.

It is a place to monitor crime activity, and to be a sanctuary for Bruce.

Its really pretty simple actually. First you must defacate in the mouth of your partner. They should then smear it all over their face making it look brown and bumpy like a cliffside. Next, proceed to ejaculate in and around their mouth. As they continue to hold their mouth open like a cave opening, the jizz will give it the stalactites to hang from the ceiling.
