I had greatly enjoyed eyeballing Jenny, the lady who lived in the house behind us, every time I saw her. I found her very attractive, in kind of a simple, wholesome way. She was probably about 30 to 35 years old, 5 foot six, more or less, very slender, medium length, curly black hair, narrow, but well defined, hips, very small waist, and superb little tits. I'd often wondered if she looked as marvelous with her clothes off as I suspected. One Tuesday afternoon, while the wife was off to her girl scout meeting, I was out in the back yard planning yet another gardening project when I happened to look up at the second story of Jenny's house, and what I saw was quite a surprise. Jenny was standing in one of the windows, her back toward the outside, and she was (as far as I could tell, since I could only see her from the waist up), wearing nothing at all. I found myself staring at that window, wondering if she might turn around. I thought about moving into a position with a better view, but was afraid I'd miss something. Besides, with so many trees in both our yards, I might not be able to find a better location. So there I stood, watching, waiting, wondering why she was just standing there. Her arms appeared to be crossed in front of her, and she wasn't moving, didn't appear to be talking to anyone, she just stood there, her pale skin bright against the darkness inside the room. Finally she began to turn, ever so slowly, toward the window. I could feel my heart pounding in anticipation. Was I really going to see those small, fine breasts that I had imagined? As she reached the point where I began to see more than just the back of her I realized that here arms were indeed folded in front, covering her chest, so I couldn't see her tits. I looked up at her face, and saw that she was looking right at me, with an undecipherable look. We were obviously close enough together that I knew she could see that I was looking at her. I didn't know what to do for sure. I knew the "right" thing would be to turn away and depart the area. But for some reason, I just couldn't. I had to wait and see what, if anything, she was going to do next. Still, I was concerned that her husband or my wife might show up, see me watching her, and do something I'd regret. Then I remembered that it was still early in the afternoon because I had left work early so that the wife could go to her meeting. Nevertheless, her husband could get home early too, and my wife's meeting could have been cancelled. But I just couldn't pass up this possibility to see more of her naked body. After what seemed like forever with us just looking at each other, she smiled, turned, and walked away. I stood there for a long time, hoping she'd return for the rest of the "show", but finally decided to give it up as another foolish hope for a cheap thrill. I thought about that "afternoon delight" a lot in the ensuing days, and looked for her whenever I was out in the yard, or driving by her house. I saw her a few times as I drove by the front of her house, and we both smiled at each other as we passed, but we never spoke, and I was too timid to take any sort of action to make direct contact with her about the window episode. Then, on another Tuesday afternoon, when I was finishing my exercise routine and getting ready to take a shower, I saw Jenny in her back yard, looking toward the sliding glass doors that lead to the deck outside our bedroom window. "I wonder if she would like a return of the favor?", I thought. "What the heck, let's give it a try!" So I took off my sweats, leaving only my jock strap on, and proceeded to the right side of the sliders. I pulled back the sheer curtain liners, so that she could see in more clearly. I peeked around the edge of the door to see if she was still alone and watching. She was. Then I slowly walked into the center of the doors, with my back to the outside, just as Jenny had done. I stood there like that for a few seconds, then I slowly turned toward the doors. When I finally reached the point where I could see where Jenny had been standing, I couldn't see her. "Shit!", I thought. Then I turned all the way around, and saw her. She had moved closer to the fence that separates our yards, and was looking right at me, smiling. I smiled back, and started to wave, but she suddenly turned and walked toward her house. "Dammit!", I thought, "What the fuck is going on here?" Then I saw Tim, her husband, coming out into the yard. Just as I had feared, he too had come home early. I jumped back and closed the curtain sheers, thinking he was going to see me. He was not looking for anything like that, fortunately. He just proceeded out to their storage shed at the back of their yard. "Whew!" I could finally breathe again. As I took my shower, I couldn't help but wonder what would have happened if Tim had not shown up. Worse yet, what if he had shown up without Jenny realizing it and he'd seen what was happening? "I better forget this whole nonsense, before I get in big trouble.", I thought. Try as I might, I couldn't get the idea out of my head that I had to find out just how far Jenny might want this "lookey-loo" stuff to go. I had just gotten myself into pretty good shape for a guy in his forties, and would enjoy showing off to her again, and I thought maybe she needed to have someone other than Tim appreciate her loveliness as well. It was even possible that she was attracted to me enough to want to go beyond a visual relationship. The very next Tuesday, I saw Jenny at her window again, her bare backside to the window, the thin tan line once again hinting at joys not yet beheld. I waited for quite awhile. Then, finally, she began to slowly turn toward the window, arms crossed, just as before. When our eyes met, she very very slowly began to move her arms outward, toward her sides. She kept her forearms at just the right position such that I could not yet see her tits. When she got to the point where only her hands covered her tits, she stopped. I looked up at her face and nodded approval, as if to say "go ahead". To my chagrin, she didn't move her hands, but rather, she shook her head "no". Confused, I put my arms out to the side, tried to look sad, and mouthed an exaggerated "PLEEEEASE." Again, she shook her head, but then, in one motion, she removed her hands from her breasts, and turned quickly away, so fast that I only got a glimpse of her nipples (at least I think I did, but I had forgotten to put my glasses on, so I wasn't positive). Disappointed, I stood there a short while to see if she'd return. When she didn't, I went back inside. I was really excited, so I rushed my exercises, and when I got in the shower I made certain that my cock got REALLY clean! At this point, I was fairly certain that Jenny wanted to go farther with the showing off, but I was unsure about what she might ultimately have in mind, and I had no idea what she might want me to do next, if anything. I pondered the question frequently for the next several days. Each day I would go into the yard and check the window for signs of Jenny. If she wasn't there I'd do my exercises and check the yard before showering. One day I saw her there, but she was dressed and cleaning the window. I waved, but she did not respond. I was really getting confused. What did she want? What should I do? I had no answers. Then came the next Tuesday, and again, after I had finished my exercises, I saw Jenny in her yard, watching our sliding doors. At this juncture I felt like I needed to get things moving ahead, or ended. So I decided to escalate the "show off" war. This time, I took everything off, opened the sheers, and walked into the doorway. As before, I kept my back to the outside. I put my arms up to the back of neck, flexing my muscles as best I could. Slowly I began to turn while lowering my hands down the front of me, timing it so that I would have my cock covered by the time I had almost fully turned. I kept my eyes ahead of my body, and I saw that Jenny was still watching, and as I completed my turn, she looked up at my eyes, and gave me the same nod or approval as I had given her. Like her, I shook my head no. Then she gave me the "PLEEEEASE" gesture, just like I had given her. I decided to give her some of the same thing she had given me, and quickly moved my hands back up to behind my neck, turned, walked away, and closed the curtains. I peeked out to watch her reaction, and saw her stay there for about two or three minutes, then shrug her shoulders and return to the house without another look. Had I been too brief I wondered, or was she unimpressed with what she had seen? Maybe the railing on the deck had obscured the view. The following several days it rained steadily, so I figured there would be no window shows, and stayed in. The next week was nice, although overcast. Nonetheless, since I figured it was still "my turn" to view, I proceeded to the back yard to check what was fast becoming my favorite window. No one there. "Damn", I thought. "I guess I should have checked last week when it rained. Maybe she think's I lost interest. Maybe she decided she was doing something too naughty. Just as I was about to leave, I saw her move into the window, her bare back facing out exactly as before. Slowly she turned, moved her arms out to where her hands covered her tits, and slowly moved her breasts up and down with her hands. I vigorously nodded my approval, and she smiled back. Then she slowly moved her hands forward from her until only her fingertips were touching her breasts. I still couldn't see her nipples though. Then she finally moved her hands up the front of her chest in a caressing fashion. There they were, the prettiest little tits I have ever seen. Just the right shape, and perfectly white. Dark areolas, just slightly larger than the nipples, which were big enough for me to see clearly. I was captivated by the sight. She stood there for quite awhile, while I stared like a schoolboy with his first "Playboy" magazine. Then I looked up and smiled and said "Thank You". She couldn't hear me of course, but I think she understood. She smiled, caressed her tits and her nipples a little more, turned, and left. I stayed for a few minutes, just in case. But I that was it for that day. I got even cleaner in the shower that time. By now it was clear that Tuesdays were probably the only days that anything might happen, so I decided to take the whole next week to figure my next move. I had already let her see all of me, so there was nothing to add, except to make it take longer, and maybe tease a little. When the day finally came, I saw her in the yard waiting, and took up my position. But this time I had a long T-shirt on, that came down below my otherwise uncovered butt. I turned around a full circle, and when I was again facing away from her, I slowly lifted the shirt up over my head, and held it in front of me as I turned back to her. Then very slowly, I lowered the tee shirt down the front of me until my hands were in front of my cock, held that pose for a few seconds, and then let the shirt fall. I looked at Jenny, and she gave me a nod and an "OK" sign. I returned the sign, with both hands. This left me fully exposed to her. She watched me carefully, and I could see that she was smiling, (I hadn't forgotten my glasses this time). After a few seconds, I turned, walked out of view, and closed the curtains. I laughed at how much fun I was having, acting like an adolescent again. At the same time, the adult part of me was concerned that I might be heading into something I couldn't handle. It was getting harder and harder to wait for a week to pass, and I was very eager to get into my viewing position for Jenny's turn to display her wares. I waited by the fence for what seemed like a very long time, but finally she came into view. This time, she was dressed in a lacy white robe that you could just barely see through in the sunlight. She was almost facing the window this time, but turned to the side and bent over. She seemed to be moving something in from the edge of the window. When she stood up, she reached up to the collar of the robe and ever so slowly pulled it open and gently slid it off of her shoulders. As the frilly edges of the robe contacted her nipples, they hung there for a second, then jumped off and out of the way. There were those wonderful breasts again for me to enjoy. I wished I could caress and kiss them, but for now, I was glad just to be able to see them once more. When Jenny dropped the robe away, I discovered that she had indeed moved something in alongside her. She stepped back and to her right a little, and stepped up on whatever it was. Now I could see her tummy, all the way down to the top of her pussy hair. I made a lifting motion with my hands, trying to get her to raise up higher. Then she did something that really got my attention. She raised her left leg up and outward and put her foot on the window sill. At that moment, I knew that I was just a few inches short of being able to see her pussy. But there was no place higher and closer for me to go. Then she began gently caressing her breasts, smiling down at me all the while. I was enchanted again, locked into position, my eyes glued to her hands, watching their every move, wishing they were my hands. She began moving her left hand down her tummy, then out along her leg. Back and forth along her thigh she moved the tips of her fingers, each time getting a little closer to her pussy. Then she moved her other hand down, and put both hands between her legs and moved them up and down while leaning her head back. I was really getting hot when she looked back down at me, raised both hands, blew me a kiss, waved, stepped down and disappeared. I was so excited that I actually thought seriously about going over to her house and seeing what I could get going, but decided against it. While I wasn't sure of her ultimate intent, I figured that it was much safer to assume that playing the voyeur/exhibitionist game was all she really wanted to do. The next Tuesday, I couldn't wait to get home and get the wife off to her meeting. However, since it was my turn to show off again, I once again had to figure out what to do this week. I had already shown it all twice, albeit briefly. I decided to check the scene out before I did my exercises. I looked out back and there was no one there yet. Fortunately, it was a nice day, not too cool, so I decided to open the sliding doors and actually go out on the deck if and when Jenny got into her viewing position. Fortunately, I only had to wait a few minutes. When she arrived, she had a folding chair, and some sort of case. It looked a little like a camera case, but it was to big for the simple cameras, and too small for a 35 mm SLR type camera. "Oh well, what the hell" I figured. So I took everything off and put my bathrobe on. Then I walked out onto the deck, facing Jenny. She didn't seem surprised by my coming all the way out of the house, she just smiled and waved. I waved back and said "Nice day". "So far", she replied. As I reached for the tie-string on my robe, Jenny reached into her case, and removed a small set of binoculars! I was surprised and uncertain, but decided to press on regardless. She put the glasses up to her eyes, and I untied the robe string, began to pull the robe apart, and turned my back to her. "Hey!" she said, almost too loudly. I looked back over my shoulder at her, and slid the robe off my back and let it fall to the deck. She just watched, not a word, no movement. "Well, here goes", I thought, and I slowly turned toward her. She then sat forward in her chair, and let out a whistle as I came into full view. I hadn't realized it until then, but my cock was fully erect at that point. "Thank goodness for all these trees", I thought. "If any of the other neighbors should see this, I'd end up in Jail!". To my amazement, Jenny made
