We are a happily married couple, almost 20 years now. Over the years I have gotten to know my wife pretty well and can usually anticipate her desires. This time however, she even shocked me. We are in our thirties and she has always had an appetite for sex. A beautiful woman with large DD breasts and soft white skin. The other day, she had an appetite for pizza, or so I thought. It started with her suggestion that we order pizza delivered on the day we had the house to ourselves. She seemed a bit more anxious for the delivery than usual. She watched out the front window with the curtains slightly parted for whoever would be the delivery guy. When she saw the car pull up with the sign on top, she scrutinized the very young looking man who got out with a box. I didn't get much of a look at him myself, but I would get more than an eye full soon. She looked at me dead seriously and said "go in the kitchen and be quiet." Wearing her purple robe and nothing else, I knew she was in a naughty mood. The smile on her face told me I should comply, because she had something fun on her mind. I found a spot to put down my chair that I could see through some curtains into the living room and the front door, but not be seen to the casual observer. My lovely wife opened the door on the first knock. "Hi there, pizza delivery." He reached out and tried to hand her the box. She replied with a "Come on in, leave the pizza right there on the end table while we get you paid." The delivery guy came in and sat the pizza down, handing her the receipt and I got my first real look at him. He didn't look a day over 16, young looking face with a very slim body. Short dark hair under a hat with the pizza companies brand and a polo type shirt with the company logo. He was wearing dark slacks and slip on shoes. His young face looked like he didn't need to shave very much either. My wife casually walked over and closed the door, then walked into the kitchen next to me and grabbed her purse, then went back into the living room fumbling through the purse for money. "I will pay you for the pizza, so you can pay your employer, but I want to give you a special tip if you don't mind." I could see, through the curtain, that as she said that to our young guest, she put her purse down and undid her robe, exposing a breast and thigh along with her trimmed pussy. Without waiting for a response from the stunned boy, she walked right up to him and got on her knees. I watched, slightly stunned, as she began undoing the boys belt. I was instantly hard and more than a little concerned that he would go running out the front door screaming rape. He responded with "uh, ummm." and nothing more. I could see my wife undo his fly, then pull down his pants, allowing them to drop to his ankles, then she slid her hand into his boxer shorts, fishing for her prize. When her hand came back out, his flaccid dick followed, flopping lewdly out of the fly hole in front of her. He looked down at her sheepishly, before she slid her soft lips around his member. I involuntarily reached for my dick, pulling my own penis out of my pants and began to masturbate to this incredible site. She began sucking this young man rhythmically, back and forth as his dick grew into a full-fledged hard-on in her mouth. He rolled his head back, looking at the ceiling and closed his eyes as she worked her magic on his tool. I was ready to explode, with my view of the action working my mind into a frenzy. That's when she really surprised me. She pulled his hard cock out of her mouth, her spit trailing along his shaft giving me a good view of his nice young prick with a large mushroom head. "Do you have a few minutes?" she said. "Let's go in the other room." With that she stood up and led him, wobbling in his pants around the ankles with his member poking out of his boxer shorts toward my bedroom. MY BEDROOM, was she going to fuck this kid and do it in my room? I waited, afraid of giving myself away, before moving into the next room and attempt to see what was going on. I stepped lightly, afraid of betraying my secret excitement by being discovered. I cautiously peeked around the corner toward the bed. I could hear the noises made by the moving of box springs and sheets on skin. I was rewarded by a sight that almost took my breath away, and definitely gave my penis a jolt. As I peeked around the corner all I could see was his large bare feet, his soft bare buttocks and his balls, thrusting back and forth between my wife's open legs. This boy was humping my wife, on my bed, in broad daylight with me in the next room. His thrusting was frantic, hard and fast. My lovely wife began making noises and I could hear him grunt with every stroke. His soft, almost hairless balls flopped back and forth as he worked her pussy like a pro. Then it struck me, this kid was fucking my wife bareback, he was on the verge of cumming in my wife's bare pussy with his young spunk. That's when I came, hard, all over the floor in front of me. Watching him was too much, hearing her moans and his grunts, a few minutes later he did the same, flooding my wife's pussy with his thick cum, he collapsed on her for only a few moments, before jumping up off the bed. I beat a hasty retreat to the kitchen and out of sight. A few minutes later I heard the front door open and close. "You can come out now," said my wife. I walked into the living room and she was already retrieving a piece of pizza from the box. "Wow, that was different," I said. "Ya, but the pizza is cold now, he didn't even let me pay for it," said my wife with a grin. I could see a small trickle of cum working its way down her legs, I was going to have to let that pizza get a bit colder, I had to take her to my room and fuck her good before I lost control of myself. We like pizza.
