The lab where Dr. Angelina works just made the breakthrough of a lifetime: an invisibility potion! Once Eva realized the mega fortune they had on their hands, she grabbed the test-tube and ran for it. That night, her boss Dr. Sins drank some potion and raced to her house to get it back.

The first thing to re-appear was his fat cock, which Eva was only too happy to wrap her slutty lips around and suck the hell out of.
