You blush slightly as your enormous cock throbs under your gently stroking hand. "I gotta try this out." You sit back in the tub and rub some lube from below your sink into your massive organ as you begin to masturbate, your hand sliding up and down with slow cautious strokes over your massive sensitive organ. Your hot balls rest in your lap as your massive cock sways with your every stroke as your hand begins to pump faster and faster. Your back begins to arch as your legs stiffen, your balls contracting as your quickly approach climax, your pleasure and groans blocking out any of the outside worlds intrusions.
Finally you cum, sending a blast of hot semen arcing into the air to come down with a heavy splat in the tube. You fire again and again and again, your climax dragging itself out as your world is awash in pleasure and cum, semen slopping in the tube as you suddenly hear a knock on the door.
Who is it?
