Sex act where the man wraps his penis in tinfoil before oral sex. The woman should never look away from the man's penis, thus the 'museum' element.
Corey learned the hard way that it's important to smooth out the tinfoil before having your girl take you to the 'Aerospace Museum', however he did enjoy exclaiming 'Clean up in the cockpit!' afterward.
