On a rather humid evening while i was lingering in the a/c in the house, minimal clothing was my preference, and by minimal i meant my mankini underwear, and they were tight as well enhancing my bulge greatly. The bedroom was the most comfortable so i lounged around watching TV only getting up to travel to the fridge refreshing or refilling my cold drink. I stopped at the mirror and looked for mom's reflection. I guess she thought the same about the humidity as she was sitting in her chair reading and in minimal attire also, a thin white bra and gym style shorts. Now mom was around 50 at the time, a sprinkling of grey in her short black hair. a little flab here and there but not a great deal of it. Her tits were about a 36c I figured because she was similar in size all around to my wife, 5'5 ish and around 135 to 140 pounds give or take, about a 28 inch waist and another 38 around her ass. 36,28,38 i estimated.
Anyway,,, i strode over to my chair, I didn't sit immediately. I stood facing the window and stretched my arms high, turned from side to side in a twisting motion and stretched my hands to the floor stretching my back and hamstrings trying to look as nonchalant as possible. I straightened up, adjusted my dick in my mankini and walked back to my position at the mirror. Mom was leaning forward toward the window looking in my direction. My dick expanded and tightened my kini a bit. Her stare confirmed to me she was watching.
The very next evening my mom invited me over for dinner. The humidity was terrible again so i wore gym shorts and a tank top. Mom was wearing a ratty old tee shirt and casual white shorts that stopped just above her knees, comfy and conservative. We ate and shared small talk for a bit and darkness snuck up on us around nine pm. I was sitting in her reading chair and looked across to my window. I could make out the big mirror and everything in its reflection. If thats the case, even when I felt hidden watching her she could still see me in that same manner. At that time i said my goodnight and headed across the street. In my head i was wondering whether to change my plan or let it play the way it was! i decided to leave it be and just carry on.
In the humidity i shed my clothes almost immediately upon entering my house. Full nudity tonight. I grabbed a cold soda and headed to the bedroom stopping at the mirror and checking across the street. Mom was stending by her chair peeling the tee shirt over her head with her back in my direction. She was braless. still facing away she slid down the shorts, no panties either, her ass looked amazing even from that distance. I was standing, staring with my mouth hanging open and my hand wrapped firmly around my semi hard cock. When mom turned to face my direction. Her dark nipples and trimmed black bush were clearly visible. My dick reached full mast. Neither of us moved, we just stared in each other's direction! We both knew the other was watching and showing intentionally. Our long secretive exhibitionist/voyour perversion was out in the open. From the reflection in the mirror I moved over directly in front of the window, mom stood motionless and watched me watch her. In reality we weren't watching anything, just staring. That continued for about fifteen minutes before i just sat in my chair and she sat in hers, both of us bare assed naked.
Over the next couple of days the game continued. We witnessed one and other being watched through our windows by passers on the street, none wise to the fact that a mother and son were playing a sexy little game and they were the beneficiaries. About a weeks worth of play went by and mom invited me over for dinner again. This time she answered the door in see through black longline bra, matching panties and garter with black fishnet stockings. I stripped down to my mankini underwear immediately after entering. We sat and talked about our adventures for a bit, sharing stories we never had a clue about over the years. We ate dinner, talked more, laughed at times at some of our escapades. During the evening mom changed to a different outfit, all very revealing. Being a man I didn't have options for clothing changes so i just bared all and hung around naked, openly stroking my cock from time to time. Eventually mom went on full display as well. Lights on, blinds open we watched as each of us paraded around her house naked, watching from hiding as passers by took in whichever view they were alloted. We played this game for a few weeks in person and from window to window almost nightly.
After a couple of weeks the intensity increased. We started touching and feeling, stroking and fondling and masterbating. We took pictures and videos. We set up a video camera on a tripod so we were both free from handling the camera and would watch our performances while videoing ourselves watching ourselves!
On the game went!
Fate eventually came into play, it was hot, humid and raining. We were into the game and naked mom was standing in front of the window. I was watching for a passerby when the urge hit me to sneak up behind her and press my cock against her ass. My hands went around her and i began gently squeezing her tits. her head tilted back and i started kissing her neck and nibbling her earlobes, grinding my cock against her ass. I momentarily stepped away, turned the video camera in our direction and switched it on. I moved back to my position behind her and resumed what i was doing. Pre cum was smearing on moms ass, she was moaning and quivering. She reached back and started stroking my throbbing cock. I turned mom around slowly, kissing her passionately on her neck as she turned. When eventually she was facing me I pressed my mouth to hers and shot my tongue into her mouth savagely. Our tongues wrestled and I ground my cock against her belly. My hands went to her fleshy asscheeks and squeezed them roughly causing her to moan into my mouth. We worked our way to the wall beside the window and with her back against the wall I lifted her up. Her hand was frantically maneuvering my cock around until I felt it part her cunt hair and find the channel leading to her soaking wet opening. Once the position was just right I didn't enter, i just tickled the outer edges and her clit with the head of my cock which was ready to explode. Enough was enough, I lowered her and thrust forward and buried my cock to its limit with one thrust. I didn't stroke in and out, I just held her steady while fully buried inside of her. Mom was shaking, moaning, biting my lip, clawing my back. Her eyes were glancing at the TV where the video camera image was fully displayed. Without pulling back or thrusting just the heat an shaking taking place i erupted cum deep in moms cunt. I spasmed and shook and remained deep in her guts. The hardest orgasm I'd ever experienced. Mom began to cum just as hard. Juice was running down our legs and forming a puddle at our feet. My dick began to soften and slip from moms insides. I lowered her to the floor and neither of us could stand firmly, both wobbling and giggling. She dropped to her knees and took my now limp cock in her mouth while watching her performance on the TV screen. She sucked like she was starving. I was looking out the window and the rain was still hammering down, seemingly ruling out any possibility of an observer passing by. Maybe next time. With mom finished cleaning my cock i got dressed and headed across to my house in the rain. An hour later my wife came in from work. I was in the bed facing out the window watching mom sit in her chair most likely watching the video we had just made over the past couple of hours. I know I couldn't wait to see it!
