There was probably nobody in the world who'd be at all surprised to discover that Wally Wanka wasn't Chester's real name. Chester Herbert wasn't the sort of name you'd choose to use on the sort of internet site he frequented. But Wally Wanka was the online name he'd used for so long and so often that he almost considered it as much his real name as the one he'd been christened with.

And Wally Wanka was the kind of jokey irreverent name that helped give Chester something of a presence on PornBB, xHamster and PornHub where he'd upload movies that he'd earlier downloaded from Bit Torrent; raise a laugh on sex story sites like Storiesonline where he often lurked; was required on cam sites like Jasmin and Streamate; and was all he was ever known as to other members of paysites like VideoBox, RealityKings and Digital Playground.

Chester's online name was, of course, a very poor pun on a fictional character from Roald Dahl's Charlie and the Chocolate Factory, but it appealed to his quirky off-centre sense of humour. And this also made him famous on the many forums he contributed to, whose members were generally rather affectionate to Wally Wanka and his witty references to Oompa Loompas and the Golden Ticket he promised to reveal in a very special chocolate bar.

Although almost all his waking hours when not at work or asleep was spent surfing porn on the internet, Chester had a hidden talent he'd never revealed to anyone apart from the millions who might stumble across his Facebook page, his Tumblr site and the many forums he contributed to. And that was to come up with new ideas for porn movies, sex stories and comic books. And these he freely (and sometimes privately for no charge) made available to those who might be interested.

One such idea, for instance, was to take the scripts for television series from the 50s and 60s which he was sure were no longer bound by copyright and use them as the scripts of online sitcom streams. These would only differ from the original in that they could now be filmed in colour (and on equally unconvincing film sets) and in which all the actors and actresses were naked. This would resemble those Japanese zenra movies where ordinary activities such as going to school or working in the office were filmed in the nude and in which the genitals were covered by a mosaic gauze. But unlike these films, it would be a weekly serial and actually have a decent storyline. As a variation, the male roles could be played by naked women with dildos strapped to the crotch. Chester was sure this was a project that would be a hit if only someone could take him up on the idea.

Another of his ideas was to make a spanking movie based on The Sound of Music. All those scenes where the von Trapp family children misbehaved would earn a spanking or caning where red skin and welts would be displayed on the buttocks of the naughty (certified 18+) children. And the scene at the beginning where Maria sings the title song would feature a porn star playing the postulant entirely in the nude. Chester could imagine Nicole Aniston or Jessie Jane waltzing around those Austrian mountains with her boobs on full display. And just imagine the possibilities presented by the nuns and Mother Superior at the Nonnberg Abbey!

Chester (or Wally Wanka) was full of such great projects which with a bit of financial backing, some great porn stars and a lot of masturbation could only be huge hits in the world of porn. What about a porn version of The Apprentice, but for real rather than as a parody spoof? What about a nude or BDSM Sports Channel with real leagues for competitive fucking? What about a version of The Truman Show that followed a porn star or prostitute wherever she went and with whoever she fucked all in real time? When Chester saw that someone had already taken up one of his ideas (such as a parody movie of The Wizard of Oz or the sexualised wrestling in Ultimate Surrender on Kink.com), he often wondered whether the producers had been originally inspired by a Wally Wanka post. And if they had, shouldn't he (or at least Wally Wanka) get some of the credit.

The sleeping part of his life was generally easy, though he often found it difficult to get comfortable. And that was because Chester tipped the scales at somewhat over a hundred kilos. And the reason he was so much out of shape was entirely due to a lack of exercise and a surfeit of Domino's Pizzas. The waking part of his life was dominated by porn. This consumed almost every hour he was awake, even though there was only so much time in the office he could spend surreptitiously surfing on his iPhone. Frustratingly, there were also times when he had to do the work for which he was paid. And this was as a system tester in the Council Offices for the London Borough of Waltham Forest. He'd had the same position for over ten years and could see no scope or opportunity for promotion. Especially so as he generally did as little actual work as he could get away with.

He also lived in the same one-bedroom flat on Forest Road, Walthamstow, he'd bought when his father died and left him with enough to put down a hefty deposit. He never contemplated moving anywhere else. It was within easy walking distance of the office. In fact, everywhere he could possibly want to go to, including the train to Central London (if he ever wanted to use it), could be reached on foot: even by someone as obese as him.

Of course, nobody online knew that the witty and sparkling Wally Wanka was also the tall but also fat and flabby figure that could be seen walking along Forest Road with a fashionable beard (of an unfashionable scruffiness) and almost always munching on a sandwich or chocolate bar.

His secret was secure.

Or so he thought until he came home from work one day and encountered the woman from the downstairs flat in the shared hallway of the block of flats where he lived.

"Who's this Wally guy whose post arrives here?" he was challenged.

She was holding a brown parcel in her hand that probably contained promotional material from one of the porn paysites to which he belonged.

"Wally?" said Chester caught totally unprepared. Just what was his cover story? "He's just a guy I know from work who hasn't got a permanent address. He gets his post sent here and I collect it for him."

"Oh," she said handing it directly to him. "Weird name though isn't it? 'Wanka'. Is he Polish or something?"

"Lithuanian, actually," said Chester.

"And I've seen your name on some of the letters that arrive," the neighbour continued. "Are you Chester? Or is it Herbert?"

"Chester."

"And my name's Cheryl," said the woman stretching a hand out towards Chester. "Pleased to meet you."

And then for the first time since he didn't know when (probably on the rather embarrassing and ultimately unsuccessful occasion when he ventured into a massage parlour on Hoe Street) Chester touched a woman. And in this case all he did was shake her hand.

Chester had never really noticed his neighbour before. He didn't know whether she'd only just moved in or had lived there for years. He didn't know whether she had a husband or children or a pet or anything at all. And he certainly didn't know that her name was Cheryl. She was also in her late thirties. Age had crept up on her as it had on Chester. Her skin was less elastic, her hair was almost certainly dyed and she most definitely didn't have the figure of a teenager. In fact, she probably didn't have much of a figure even when she was a teenager. It was difficult to know how to describe Cheryl's figure at all. The word 'shapeless' sprang to mind, but of course that ignored the fact that she did have a shape. It just didn't conform to the expectations made, for instance, of a porn model. Her breasts weren't large. Her waistline was best described as chunky, if not flabby. And her legs and ankles had a matronly aspect (although most porn matrons had rather more slender ankles).

"Well, I must be going, Cheryl," said Chester with an awkward emphasis on her name as he turned around to thunder up the stairs.

"If you ever need anything, Chester," she called up to him as he put his key into the lock of his door. "Just call. You know which one is my doorbell."

"Of course," replied Chester as he pushed open the door of his flat to enter its slightly fetid warm air (he always set the central heating up to high).

Ahead of him was the welcoming sight of the expensive 30 inch monitor he'd attached to his high-end games-spec desktop computer. He wanted to see his porn in the best possible conditions. He wondered what it was that had been sent in brown paper to him (or, nominally, Wally Wanka) all the way from Sacramento.

Chester soon forgot his awkward encounter with Cheryl and immersed himself into his alternative life as Wally Wanka. He had movies to download from Empornium, others to upload to xHamster and YouJizz, an ongoing discussion on IntPorn and another quite different one on PeachyForum. It was a busy life being a presence in the world of online porn.

It was a day or so later, a Sunday night in fact, that Chester was slouched in front of his high-spec monitor with his trousers down below the knees and the cock in his hand reluctant to stiffen. It was while watching Bonnie Rotten spasm noisily and repeatedly as three or four men competed for all her available orifices that he became aware that his doorbell was ringing. Shit! Who could it be? He hadn't ordered a pizza. He'd already gorged on an All-You-Can-Eat at the local curry house, so he wasn't yet hungry again.

Chester pressed the three keys necessary to lock his screen, pulled up his trousers and tossed away the tissues he'd spunked into earlier that day. He then walked to the intercom and pressed his face to it.

"Who is it?" he called in the requisite sing-song voice.

"It's me, Cheryl," said the voice on the other hand. "I've got a bottle of wine that needs drinking. Can I come up?"

"Erm..." said Chester who was wondering how he could most politely turn her away. He was looking forward to seeing Bonnie Rotten come. And there was also that video he wanted to watch with Stoya and her partner, the ubiquitous James Deen, doing the honours. But he couldn't think of what to say. "Yeah. Come up. It's OK."
