Michelle 'Bombshell' McGee -- Sex Tape Surfaces -- Rub-A-Dub-Dub, Baby

Jesse James
' former mistress Michelle "Bombshell" McGee got down and dirty with 2 tatted-out sex freaks this year -- and the private XXX liaisons were all caught on tape ... tape that now lies in the hands of a giant porn company.

Sources tell TMZ, the footage documents two separate sexual encounters -- one with a tatted-up man ... and one with a tatted-up woman (above) ... both shot within the last year.

It's unclear how, but we're told the tapes were acquired by porn giant Red Light District -- the same adult studio that released the infamous "1 Night in Paris" -- and it plans to release the footage early next year in a 2-DVD box set.

And there's this -- we're told there's even more Bombshell sex footage floating around, but it's so extreme ... RLD is considering not releasing it for legal reasons.

The studio wouldn't comment on any possible deal it struck with Bombshell -- and attempts to reach Bombshell herself for comment were unsuccessful.
