She talks to me.

I almost jumped out of my skin when she said to me, "So did you enjoy the show?"

I stood their frozen, hard cock in hand, not sure how to answer her question when she spoke again, "Did you get your rocks off watching me, or do you want to come over here and let me finish you?"

"Umm, I'm sorry I didn't mean to disturb you," I answered my face burning red and I turned to head back to my house.

She quickly answered me back, "You didn't disturb me. I have always fantasized about someone watching me when I am out here. Come on over and let me finish you. I give great head; at least my fat ass husband thinks so."

What man could resist that? I strolled over to where she lay sprawled on the hammock. She was totally naked and from what I could see her body was great. Nice firm tits, thick stiff nipples, small waist and a firm looking ass. I could not really see her face, and my musings were interrupted by her hand gripping my cock through my open fly. I became fully erect at once and the thought that I was cheating on my wife never entered my mind. The whole scene was so surreal that I just did what she asked.

She pulled me close to her and bent down to envelope my cock in her mouth. She was right, she was a very good cock sucker, and her mouth sliding up and down my shaft soon had my cum boiling in my balls. My hands moved down to her shoulders and to her breasts to feel her firm tits while she mouth fucked me. Her nipples were big and hard, just the way I like them, and I rolled them between my fingers as she slurped and sucked on my hard prick.

I moaned quietly to her that I was going to cum, and she did not miss a beat. My wife always wanted me to be as far away as possible from her mouth when I blew my load. She made it very clear that she did not like the taste of cum, and if I did not warn her soon enough she would be pissed. The woman sucking my cock now had no such worries. She took my cock to the hilt in her mouth as I began to ejaculate. She gulped down my load without blinking an eye, and I could hear her moan as I stimulated her nipples.

When I finished spewing in her mouth she released her warm mouth from my shrinking cock, and sat back in the hammock as she had been when I first met her. She laughed and said, "You're welcome stud."

I became embarrassed again and said, "I'm sorry this whole thing caught me by surprise. You were great, by far the best blow job I have ever had."

I could see her teeth as she smiled at me and said, "Like I said stud, you're welcome. By the way what's your name, you must be new in the neighborhood."

I answered her truthfully, but I was beginning to feel very guilty for cheating on my wife, "My name is Steve, my wife and I just moved in today. She's in bed"

"Yeah, I didn't figure she sent you out to have sex with the neighbors."

I said, "Yeah, about that, we can keep this between us right?"

She stood up, and I realized she was tall, almost as tall as me and laughed as she headed back towards her house and she said, "Yeah, I suppose. I'll see you around."

She was gone so fast that I was still wondering what had happened. She didn't exactly give me confidence that she would keep our little tryst as a secret, but I didn't know what I could do about it. I also realized that I had not gotten her name. I suppose that I would recognize her in the morning.
