Hot Rod Enhancer

My kid brother comes up to me and says, "Yo, big L, I can't fill up my bitch."

I say, "Okay, pencil-dick, you've come to the right place.  What you need is the Hot Rod Enhancer.  It'll increase your girth, and that'll bring a smile to the scrawny piece of chicken you politely refer to as your 'bitch."  "How's that possible, Knower Of All?" he asks, blinking innocently.

"The tiered ridges of super-stretchy senso-material really make a dif, stupid," I reply.

The next day the freckle-faced punk comes over all happy and says, "Guess what, Big L, that Hot Rod Enhancer really worked.  I fucked my bitch, I mean girlfriend, and she shrieked Oh God, you're so big the whole time I was inside her."

"Excellent, little buddy.  Hot Rod Enhancer gives your shaft that extra big thickness you need, and it's transparent so no one will know you're wearing it -- except you and God Almighty."
