The Neighbour's exhibitionist son

I hope you all enjoy and if you do why not check out my other stories

 The boy had become a man and I had witnessed the changes and transformations, observing as he began to push through the chrysalis of his youth, eventually shrugging it off the shell to display his manhood, quite literally.

His dark blonde hair had gone from a limp lifeless lack of style to now being slickly parted on one side with hair product giving it volume on top, and cropped number one  back and sides. The lean almost scrawny body that once lacked any shape or form was now muscular and manly, his fashionable fitted clothes ensuring that he showed it off.

Tim greeted me as usual in the morning, not once acknowledging the previous night as he spoke cheerfully, my attention drifting down the tight fitting white T that hugged his tapered torso, and lower to the faded skinny jeans and how snug a fit they were at the crotch.

I could make out the side that he was dressed, and found it easy visualise how his cock would look hanging between those muscular thighs right now. But having seen him naked so many times in his room I didn't really need the silhouette to imagine how his cock looked.

We eventually went our separate ways with a goodbye and I wondered if I should have brought up his previous evening’s entertainment at the window, not to mention my own display.

That night I was running late and I dashed up to the spare room and found Tim already in his room naked. I watched through the binoculars, his flaccid dick flopping around as he wondered about his room in his usual fashion, ever so comfortable in his skin. So I watched for a while longer whilst he was still unaware.

I turned on the lamp and immediately his gaze was out the large window and across the void between us. Tim picked something up and held it against the window, a piece of paper with a phone number written upon it.

With my mobile phone quickly pulled from my pocket I tapped out the digits and waited for it to ring. He must have had an ear piece in ready, I watched his fingers go to the side of his head, the brief ringing replaced by the sound of Tim's breathing, his hand reaching down as he began to grope himself, tugging and pulling, quickly starting to awaken his dick as he looked in my direction.

His dick didn't grow much, but then there was no need considering the five or six inches of length when soft.

Tim said nothing, so I began the dialogue "do you like me watching you play with yourself? Spying on you in your private moments when you are alone in your room, naked and stroking your cock"

There is a sharp intake of breath followed by "yeah I do"

"I can see that you are almost fully hard already” I commented as he began to wank “stroke it slower, there is no rush" I added

Tim's pace slowed down at my request

"Put some lubrication on your cock and grease it up good for me"

Tim went to fetch his personal lubricant and returned to the window before applying it. I watched his hand glide up and down his glistening wet cock as I listened to his groans of pleasure.

"Put your hands behind your back so I can admire your cock"

Tim complied and I scrutinized the impressive engorged member as it bobbed a little, the blood pumping up the long length, the foreskin pulling tight around the large crimson head.

"You like to show off don't you? Showing off that big ol' cock of yours"

I didn't need a reply, his cock jumped as confirmation.

"Now spit on your palm and smear it over your big cock. I want to see you wanking for me"

I heard him as he spat on his hand and watched as he applied it obediently, his breathing shallow and punctuated by the occasional gasp for air. He stared out the window directly at me, stroking his man sized length proudly.

We continued the game for a while. When he began to pick up the pace I would order him to slow down, and when he looked to be getting too close I would order him to stop.

I had him playing with his nipples, first tenderly, then pulling and twisting roughly. I had him turning his back to me and showing off his butt, getting him to spread his firm cheeks and lean forward.

He obeyed my every command, even when his face looked like he was desperate to cum. But again and again I prevented him, until finally he got the courage to  ask with breathless words “I need to cum, can I cum?”.

I left a purposeful silence, not responding to his request and making him simmer for a little while, until he doubted I had even heard him. His voice sounded desperate as he asked yet again, this time begging "please may I cum"

I smirked and responded in a whisper "go on... shoot your load for me"

His whimpers and groans filled my ear and at last I would get to hear as well as see him shoot his spunk. His body shook and quivered, his knees buckling, his voice trembling as he spoke “I am going to cum... I am going to cum... I am going to cum”.

 His thick load was expelled with force, big globules of nut butter landing on his cheek, chin and mouth. As his body convulsed in a fit of orgasm he stuck his tongue out and removed the jizz from his lips.

 “Thank you” Tim said with a sigh of relief as his muscular body relaxed, his cock still gripped by his fist. I watched as he loosened his grip and raised his palm to his mouth, his tongue lapping his hand hungrily. “Oh yeah” I groaned as I began to wank with a rapid pace, excited by watching him devour his own spunk. He tugged on his softening cock and scooped up a further batch which he licked at as he looked in my direction, listening to the excitement in my breathing as I announced my own ejaculation loudly “I am going to fucking cum!”...

My phone was flashing when I picked it up before walking the dog the following morning. I swiped the screen to see a message from Tim with a video file attached. I smiled and opened the file, his sexy face filling the small screen, his crystal like sapphire eyes twinkling mischievously.

He held the phone out and I could make out that he was the living room, and there in the background fast asleep on the couch, his dad. Tim held the phone at a different angle to show that his sweatpants were halfway down his thighs and his cock was stood proudly.

The phone was held alongside his cock as he stroked, his dad visible just feet away, oblivious to his son’s bold actions and the part he was playing.

I could relate to the thrill he was experiencing as he recorded himself masturbating in close proximity of his slumbering father, the risk factor adding to the sensation. The exhibitionist in him probably needing to push the boundaries occasionally to experience the same high the way a drug user has to up the dose.

Tim stepped sideways, closer to his dad whose snores could be heard loudly over the phone speaker, his mouth open wide as Tim got as close as he dared, his erection just a foot at most away from his dad's face before the video ended.

Fuck I was aroused and horny as hell having seen the brief video clip. I quickly sent a text message response with a multiple thumbs up icons before watching it on repeat and furiously wanking off a load.
