Are these scenes linked together? I'm thinking yes. The white guy says, "Um. How about you take care of my man "Elize" over here?" -- that's nobody I know.
Her co-star in the first link never shows his face. Only towards the end of the clips where she starts giving him a blowjob.
The studio is Pink Visual. XBang has it's domain up for sale. XBang is defunct.
For the second link, Amber's iafd has her working with Shane Diesel for Pink Visual. However, the guy doesn't look like Shane. He kinda looks like Nat Turnher.
See what her data18 entry has under Pink Visual.
Then again, this could be a real amateur production ... that niche may be the premise that the director and producer are going for. The only star you'll know here would be Amber.
