My best friend Mark has always had the habit of mooning me and showing me his penis. I’m sure he never knew how much it turned me on.
I was visiting him last weekend when, as usual, he flipped his dick out of his pants. “Man,” I said, “if you show me your cock one more time, I’m going to grab it.” He gave me an odd look but didn’t say anything.
He got up a couple of minutes later to go to the bathroom and couldn’t conceal the bulge that had formed in his pants. When he returned, he sat down on the couch beside me and quietly slipped out his slim six-inch dick. I grabbed that luscious-looking hard-on and began gently stroking it. It throbbed in my hand.
