In a secret underground lair, a dedicated fan of Mario's plumbing skills has been waiting, eager to put their own special skills to the test. As Mario, unsuspecting, steps into the dimly lit room, the gummer pounces, wrapping their lips around his cock, which hardens instantly at the unexpected attention. The gummer works diligently, applying just the right amount of pressure, their tongue swirling and flicking, drawing out Mario's pleasure until he can't help but let out a loud groan, his body tensing as he releases his load into the eager mouth. The gummer swallows every drop, licking their lips, satisfied with a job well done.
