A New Flame

She'd always shown an aversion to masturbating me until then. Now she squeezed my hard-on firm and steady as I swept it deep up into my imaginary male lover's bum.

"Tell me how it stinks," she cried out, rubbing at herself with rough, rapid strokes. "Tell me how nasty it smells when you're bumming some bloke up his shitty arse!"

I grinned at her, hugely turned-on that she was fingering herself in front of me. I'd asked her to before - I loved to see a woman pleasuring herself, especially if she's fondling my cock as she does so - but she'd always said it "wasn't nice" for ladies to do that.

"It smells fierce and rank!" I blurted out, and she gasped with delighted pleasure as she frigged herself harder. "It smells of another man's shit smeared thick around my hammering cock!"

Debbie gaped eagerly at me, panting with excitement.

Even in my heightened state I found it curious that a woman who was usually so hung-up about sexual smells and so adamant that neither of our bums had any involvement in the little sex we had, was so aroused at being told what two blokes butt-fucking stunk like. Clearly my girlfriend had a serious fetish about men having smelly anal sex together, something I wished I'd known far earlier in our relationship.

"His stink grows stronger and stronger until I shoot off up inside him!" I called out, keen to excite her further. "And then I bend over for him and he gets to smell my arse too!"

"Oh my God - you let him fuck you?!" she gasped, her hand a blur between her legs as she stroked her fingers back and forth.

"We do it both ways!" I muttered breathlessly, sweeping my cock with long rapid strokes through the grip of her fist as if it was the squeeze of another man's innards.

"Show me, Robert! Show me how you let another man push his cock up your arse!"

I fell forwards, panting, so I was bent over on all fours and with my bum sticking outwards like I would if I was about to allow another man to use it for relief. My cock was standing proud, almost touching my stomach, while my balls hung low, stretching my scrotum as they swung heavily between my legs.

"Let me see your hole between your cheeks!" Debbie urged me. "Let me see where other men bugger you!"

I opened my legs more widely and pushed my arse further back so that my buttocks were splayed open exposing my coarse, hairy furrow for her to see for the first time. I could feel the bloated ring of my anus extruding outwards, yawning obscenely from all the cocks it had taken.

"Oh God, I can see your stretched arsehole!" Debbie exclaimed. "It looks enormous... obscene..."

"Do you like it?" I asked, recovering my breath. As she'd never shown any interest in my backside before, I wanted to make sure that her astonishment was borne from enthusiasm.

"It's amazing!" she laughed, moving around for a better view of my swollen entrance, puckering shamelessly through the forest of fur spilling out from my butt-crack. "You could get a really thick cock up it!"

"And I do," I laughed back. "I've let some pretty well-hung men use it when their balls were aching."

"And then you turn them around and used theirs in return?" she asked, still with her finger rubbing herself.

"That's how it works when men couple up for butt sex," I grinned. "You shag my back, I shag yours!"

She took her hand from between her legs and quickly padded over to her bedside cabinet to retrieve something from the drawer. Pulling out the vibrator I'd already seen hidden away in there, she called over to me, "Show me, Robert! Show me how horny you get when you're having that massive arsehole of yours slammed by a cock!"

Chuckling at her hitherto-unseen spirit of inventiveness, I grabbed the plastic phallus from her and applied it to my over-indulged behind.

"Oh yes! Shove it right up there!" she cried out as I slid it in one smooth motion all the way up into my bowels. "Now bend over and fuck yourself with it! Show me what it looks like when you've got a bloke bumming you hard up the arse!"

She craned in to peer at my gaping crack as I started plunging the dildo in and out of my puckered opening. She loved the sight of me fucking myself with it and started gasping and groaning as her finger got back to work underneath her pink nightie.

"Faster, Robert! Harder! Show me how much you like it!"

I did as she'd commanded, loving her new-found enthusiasm for our sex and hoping we could repeat this scenario on many occasions when I stayed over in future. I'd had no idea - not a smidgen of a clue - of her fascination for gay sex, but now that I did - now that it was obvious that the thought of two men enjoying anal was a considerable turn-on for her - I intended to exploit her hidden fetish to the full.

I turned to grin at her as I plunged her vibrator in and out of my over-stretched entrance. I knew its shiny white plastic would be streaked nastily and looking as crude and discoloured as the shaft of my cock when I'm humping hard behind a bent-over buddy, but to my surprise she didn't recoil in disgust at the sight of it. Instead she sniffed the air and grinned back at me, asking, "Is this how it stinks when you're together with a man?"

"It can get a lot rougher than this!" I laughed. "I'm used to much bigger cocks slamming in and out of my hole!"

"I'll buy a much bigger one for you, Robert!" she panted, her hand moving more quickly as it pounded away between her legs. "A huge twelve-incher so you can show me how much you like a long thick dong banging away at your stinky arse!"

"With bollocks on it!" I breathlessly commanded. "I like to feel a massive pair of knackers slapping away at my thighs!"

"Oh yeah!" she gasped, her hand now a blur. "Tell me what you say, Robert! Tell me what you call out when you're bending over and taking another bloke's cock up you!"

She reached back to my hard-on with her free hand and started wanking me roughly with long, rapid strokes. She angled it downwards towards her bedding which was a little painful for me, as my shaft was rigidly erect and pounding painfully with throbbing blood. However, I was pleased to have her masturbating me again and figured this was hardly the time to advise her on technique.

She yanked my organ powerfully and I could feel my orgasm nearing. How great would it be if she really did buy an obscenely proportioned dildo for us to have more fun like this, ramming it in and out of my huge over-used hole? I might even persuade her to hold it for herself and push it back and forth between my cheeks; perhaps even get behind me on the bed and make like she was mounting me with it.

Just think of all the stuff we could get up to!

I kept fucking myself with her current smaller model and shouted out for her benefit, "Oh God yeah! Fuck me harder! Come on! Shoot your thick white jizz up my hot shitty arse!"

She gasped as her orgasm hit in and I peered at her expression over my shoulder as she prolonged her enjoyment by making short, rapid flicks with her finger. Her eyes were tightly closed and her lips gently pouting as she luxuriated in her self-induced crescendo. I realised that all the times we'd had intercourse she'd been faking her orgasms: all the noisy moaning and breathless theatricals of her earlier performances were missing from this restrained and authentic climax.

When she'd surmounted her peak and continued jabs of her finger were yielding little further pleasure, she turned her attention towards my huge engorged member, and started pounding her hand up and down it even though it was still pointing painfully downwards in the tight grip of her fist. She wanked it quickly, making fast firm strokes up and down the heaving shaft so that my foreskin swept frantically back and forth across my shiny purple cock head and the deep furrow of my slit started dribbling with my juice.

"Next time you fuck me, Robert," she said, surprising me by wanting to continue to talk dirty even after she'd spent herself. Until that moment she had been reluctant to indulge in sex talk even while pretending to be at her most aroused.

"Next time we do this," she went on, pounding my throbbing manhood faster and faster, "I want you to take me from behind. I want you to do me doggy-style the way you bugger other men. Say the stuff to me that you say to them, tell me how much you love bumming me like I'm some hard-up stranger you've picked up for a quickie!"

My balls unleashed their semen and it squirted in long, copious spurts down from my bloated glistening helmet onto her bedding so that it made a broad, glutinous puddle. She surprised me yet again by not releasing my cock and cajoling me for dirtying her bedsheets, but instead continued to pump at my spasming shaft, kneading it up and down the way a milkmaid would work a cow's teat and seeming indifferent to the mess my over-excited organ was making.

Normally she'd have remarked on how rank my spunk smelled or how it was like having a big heaving boar in her bedroom about to sire another litter of piglets.

But this time was different.

The first thing she said wasn't a criticism, but was instead a question.

"Next time you come over, Robert, will you have met up with another man for sex, do you think?"

"Maybe," I replied, still catching my breath and still hunched over on all fours with her shit-stained white vibrator sticking out of my arse. "I dunno... it's possible."

"Please try to," she implored, "and I promise I'll buy the bigger dildo. We can have fun acting out what the two of you get up to... maybe play out different scenarios... different possibilities..."

"Sounds hot," I grunted, removing the dirty phallus from my bum and pushing myself back upright. I'd have to get some toilet roll from her bathroom to clean up the big stinking pool of spunk I'd left on her bedding. It seemed strange that, for once, I was the one fussing about smells and stains.

"I loved it when you were fucking yourself," she grinned triumphantly. "I loved hearing the dirty stuff you say to the men you have sex with."

"I... er... noticed that," I replied, climbing off her bed. "I'd better get some loo roll to clean up this mess."

"I've got a spare set of bedding in the airing cupboard," she said dismissively. Strange how she'd never mentioned that all the other times I'd got a smear of precum on her undersheet or had inadvertently rubbed my naked arse against her precious duvet cover.

"I can put it on while you fix us some drinks," she added brightly. "Then we can chat about what else we can do! I'm so pleased you told me about your homosexual interests, Robert... dating a guy who has a bisexual side is something I've fantasized about for so long you wouldn't believe it!"

"I think I would," I muttered, pulling my briefs back on before heading downstairs to pour us both a nightcap.

This was such a shock to the system I was having trouble getting it to sink in. Debbie had always seemed so prude and so fastidious about smells and things she saw as 'dirty' that it was difficult to get my head around her sudden reversal in behaviour.

As I was pouring myself a glass of white wine and her a whiskey with ice, I wondered if this new-found interest of Debbie's might represent a boost for our relationship. After all, our sex had become as stale as she'd said the vests had been that I'd worn on our early dates.

Perhaps, as strange at seemed, my interest in other men would prove to be the spark that our lovemaking had needed. Perhaps that spark would ignite a new flame that would see us develop into the sort of loving and durable couple I'd hoped for when I'd first met her.

Or perhaps I should be worried that in one night I'd completely changed the basis of our relationship. Perhaps the new flame was instead the unseen second man I'd brought into our bed; someone who had an erotic importance for Debbie that could well outweigh her affection for me.

As I went back upstairs with our drinks, I couldn't make up my mind about the way things had worked out.
