I've stolen an experimental growth injection and convince you to let me test it on you, my boyfriend. You're good in bed but a bit smaller than average. It works instantly! I love your new cock, but there's an unpleasant side effect: increasing the size has doubled the number of nerves in your cock. You are now an ultra-sensitive premature ejaculator! You cum shortly into a handjob after much starting and stopping. I'm almost reduced to tears of sexual frustration by a premature creampie after a few strokes in my pussy. I don't care how big your dick is if you can't use it!
