The XXX vid -- which we've seen -- is several glorious minutes of Bobby doing his best impersonation of Ray J ... i.e. getting it on inside a hotel room while filming himself at the same time.
Specifically, Bobby and the naked chick -- who we're told is a video vixen -- kick things off with some very specific touching ... before diving in to the full on sex-having.
The seller is clearly looking to make a buck off the sale and it's unclear if Bobby is aware the steamy vid is being shopped. We reached out to him, but no word back.
Now here he is with his clothes on.
