50 [M4F] Professional, neighborhood dad caught in the act

I am a tall, fit, handsome and well endowed man. Wearing just sport shorts and a t-shirt, sitting on my back porch, thinking I am alone. Scrolling through reddit, lost in my thoughts. First I find a beautiful woman's selfie.

I feel myself stir. Reaching down, adjusting my package I continue to scroll. Now I am on to sexy photos of strangers. Knowing I am alone, I reach into my shorts and begin to squeeze and tease. Feeling the blood flow begin to swell. I click on a video link. It is a sexy brunette on her knees rubbing a large, throbbing cock over her pretty face.

I quickly shed my shorts. Slowly stroking openly. Thinking I am alone. But you are watching.

Are you a neighbor? A friend of my wife's? You can see the precum glisten on the tip of my 8" cock. Do you continue to watch? Come closer?

What happens next?

50, 6'2, 195lb, 7" cut with salt and pepper short hair and beard.
