Visiting the local supermarket I needed to use the loo, so having a pee when an older gentleman joins me at next stand. Can't help myself but look across as he unzips and takes out his cock, I know I'm staring but it looks so good. Big and thick, he knows I'm looking so gives me a full frontal look as he finishes and turns to face me. He asks me if I like what I see, I can only nod and mumble yes. Putting his cock away he tells me he as a van on the car park and if I'm willing then I could have a closer look at his cock. I follow him out of the store and across the car park and we both get into the rear of the van. He shuts the doors and I drop to my knees, undoing his trousers and pulling them down to below his knees. I run my hand across the front of his pants and feel the shape of his big cock, tugging them down I wrap my hand around the thick shaft. After a few strokes he his now fully hard, at least 8 inches long. I pull back the skin around his big bellend and start to lick around the tip and up and down the shaft. He's moaning and puts a hand on the back of my head to guide my mouth onto his cock. I take it into my mouth and begin to move up and down, letting a bit more in with each suck. I can only take just over half as it fills my mouth and use my hand on the base to wank and suck at the same time. It his clear that he his close to coming putting both hands at the back of my head and fucking my mouth I feel his cock swell and pulse as a stream of spunk shoots to the back of my throat, several spurts later and I have swallowed most of it. Keeping him in my mouth until he starts to soften I lick and suck the last of his come. After we had finished we got out of the van and he gave me his number so that if I wanted to suck his cock again he would be ready and available. I can only say that I have made use of that number on more than one occasion.
