You grow a second penis

As this momentuous orgasm rocks your entire body, you can feel something even more ecstatic whelling up deep inside. A true crescendo of wanton desire: a playmate for your newfound organ.

You feel it as it happens. A mighty growth spurt in your flank that seems to progress almost at the same pace as your sperm seethes forth. Your fingers can feel tight, stretching skin scraping against them as they become wedged between two inhumanly rigid meatcicles.

You expend a single arm to pump each one alternately up and down. It's not long before you double the pleasure, and hose down the walls of your apartment with another thick layer of molten white chocolate.
