I was awoken by the sound of the front door slamming, car revving, and driving off the driveway. My mother heading off to work, like every weekday morning. We had lived here for several years, a quiet cul-de-sac neighborhood. I was on a break from my studies, returning home for a while.

Sliding from beneath the covers, I rose from the bed in my boxers, stepping across to the window. Pulling back the curtains, the sun broke through. Feeling the heat across my semi-naked body. Looking upon the dense woodland that stretched towards the rear of our property.

My eyes caught wind of movement in the neighboring garden. A figure. Female. Stretched out upon a lounge chair. Dressed in a two-piece royal blue bikini. Her skin gleamed in the sunlight, helped by the suntan lotion that covered every inch of her body.

Julia. Early forties. She had retained her natural, wholesome figure with large breasts, swinging hips, and legs that seemed to stretch on forever. My mother and I had know her since we'd moved to the area, over time she had become more of a step-aunt to myself. Keeping an eye on me when my mother had to go on work trips.

Her bikini wrapped tightly upon her shapely figure. The string tied upon each hip, the hem of her panties riding low, just covering the delight of what lay beneath. Droplets of sweat and lotion slid down her stomach, the fabric stretched upon the two beautiful mountains that blossomed upon her heaving chest.

Her tongue licked her ruby lips. Sunglasses covering her blue eyes. Leaving me unsure if they were closed, or she had seen me stood at the window.

I had begun to take more notice of Julia over the last few months. My hormones in overdrive as a young man, a lust for uncovering the sexual side of my humanity slowly bubbling away. I was sure Julia had caught me staring upon her beauty once too often, but never said a word, leaving just a wry smile upon her luscious lips.

Taking hold of my phone from the side cabinet. Switching the camera on, the flash off - so as not to bring attention to what I had planned. I began to snap several pictures of Julia laying in her back garden. Zooming in upon her amazing figure.

Her long legs. Shapely hips. Tight panties. Her smooth stomach, leading to her heaving breasts. Her nipples fully erect, like pebbles, in the warm sunlight.

My cock was already semi-erect, as it began to twitch even more. Growing harder. Longer. Thicker. Stretching my boxers. Trying hard to break free through the cut. I patted, rubbed across my groin, staring upon this beautiful lady.

I was still unsure if Julia had even seen me through her sunglasses, my mind was lost in a lustful urge of sexual desire that drove me to carry on. Placing my phone back down, I reached for the hem of my boxers.

Pulling them away from my body, they dropped around my ankles, stepping free and flinging them to one side. Standing there, in the bright sunlight. My own fully naked body now in front view of the world.

My hand gently grasped a hold of my shaft. Thick. Hard. Fully erect, pulsating between my grasp. I began to masturbate. Slowly sliding my hand back and forth. Pulling the foreskin over the hard piece of meat that lay beneath.

My eyes fixated upon Julia. Staring upon this semi-naked body. My mind running wild with images, scenarios, thoughts of her hand stroking me off. Lost in my own mind of sexual frustration, of not being with a girl before, and the strong desperation to cum.

My fingers gripped tighter upon the shaft. Pulling back upon the foreskin, releasing the large mushroom shaped head of my cock, freeing itself. It's one eye staring upon Julia with it's own devious thoughts.

Each stroke picked up speed. My cock throbbing as it slid between my fingers. Grasping tighter. My breathing growing heavier. Soft groans, like never before, at the excitement of masturbating over my neighbor.

I felt my balls tighten. My cock pulsating. I was about to explode, staring upon the gleaming naked skin of this lady. My hips softly thrusting in a rocking motion. Penetrating my own grip with this throbbing hard cock.

I sensed the need to cum. One large thrust of my hips forced my cock between my tight grip, causing a slight friction that helped the cause. A wave of white gooey cum blasted out like a volcano. Splashing upon the window, leaving a stain like fresh bird poop, dripping down the glass.

My body gently shaking in ecstasy. My head arched back, my eyes closed. A slightly louder groan seeped from my lips, before my mouth opened. A sound, sort of lions roar, broke from my vocal chords. A second wave of cum spewed out. My legs turned to jelly, using every piece of strength to stand upright.

Several seconds had passed, at this amazing orgasmic delight I had succumed to. Unlike anything I had ever felt before. My breathing still heavy. My cock seeping drops of cum through the slit, dribbling down upon the carpet where I stood.

My eyes opened, a slight blur of awakening from a deep sleep. A moment passed, my mind took back control of where I was, and what I had just accomplished.

Looking down to Julia's garden. She had disappeared. My heart skipped a beat. Soon thumping inside my chest. A mixture of panic and anxiety took over. A sense of deep shame, more than what I usually felt after masturbating.

Had Julia seen me masturbate at the window. I was stood there. Fully naked. Stroking my cock in full view of where she lay. I trembled slightly in fear of what could be. Stepping backwards, out of view - despite it being too late now.

A minute passed. I took a small step forward. Peeking out. She hadn't returned. I awaited the doorbell to ring. The hope. Pray, that she wasn't storming over to confront me. Or worse. Report to my mother what a disgusting pervert I was, for spying and masturbating over her.

Time slowly passed, feeling like a lifetime. No doorbell. No knocking. Silence. Had I gotten away with it? My hands stretched down my face, wiping the sweat that had fallen over me. That mixture of panic and achieving orgasmic delight showed.

I stepped out of my room, walking down the corridor to the bathroom. I needed a shower. A sense of cleansing myself of my obscene deeds I had done to this lady, who had shown me nothing but kindness.

The thought of my phone, containing the evidence of snapshots I had taken moments prior, laying open for all to view, never crossing my mind. I switched the shower on. The water thrashed down. Soon stepping inside to wash away my sins.

I was unaware that Julia had put a silky bathrobe over her royal blue bikini, approaching the front of our property. What did she have planned? Would she confront me, or, something far worse? Would something else lead to an adventure of self discovery from both sides?
