The taxi pulled up outside the imposing old house and I struggled out, which was no mean feat with one stiff leg courtesy of an Afghan hand grenade.

I'd spent three months in a military hospital while the facial wounds healed, leaving me with a wicked looking scar from above my right eye down to my lower lip. It gave me a rather sardonic looking grin, whether I was amused or not. Apparently, it was a big improvement on when I'd been shovelled into the armoured car with half my face hanging off.

"Johnny." I looked up and saw Frank, my brother-in-law, coming down the front steps to greet me with a warm hug and a handshake.

"Welcome, Mate," he grinned. "Welcome."

"Hi Frank." I smiled and looked over his shoulder to where a bundle of blonde hair and legs was galloping towards me, laughing like a banshee.

The bundle all but flattened me as it hit me about a hundred miles an hour. It was a good three minutes before it raised it's tear-stained face to mine and kissed me.

"You're here," my sister said through her tears, and then did her best to squeeze the life out of me.

Eventually we made it to the house where I sank down onto a chair in the spacious kitchen and took stock of my hosts.

Frank was a big man, at least six foot, and built like the fabled brick shit-house while his wife, my twin sister was only just over five feet but with all the energy and personality of a premier league football team.

"Are you out, Johnny?" she asked. I saw the relief on her face as I nodded.

"I think so," I replied. "But, a lot still depends on my leg."

"Is it improving?" Frank asked. I demonstrated for him how much movement the regular exercising had gained in it.

"You couldn't move it at all when we last saw you," Maureen said, still gripping my hand and looking anxiously at me.

"Mo," Frank said to her, "let him breathe, Darling.  You're smothering him."

"I'm okay, Frank." I grinned and squeezed her hand gratefully. "I'm just grateful to you both for having me."

"Bollocks, Mate," he laughed. "She would have divorced me if I had said no."

"Come and see what he's done for you, Johnny," Mo said and helped me up from the chair.

A door from the kitchen led into a self-contained flat with another kitchen, a bathroom, a bedroom and a separate living room, all on one level. I was stunned.

"This is your home now, Johnny," he said from behind us. “The door into our kitchen locks from your side so you can have your privacy, you know, for entertaining your friends."

I wanted to tell him that the only friend I ever wanted to entertain was his wife, but his thoughtfulness and kindness was almost overwhelming; I took a second to get myself under control before turning and hugging him tightly.

"I don't know what to say, Mate."

"And look, Johnny," Mo said and pressed a button beside the bath. A red light appeared on a gizmo she had attached to the belt of her skirt and a buzzer rang, too.

"If you fall or anything, help is only as far away as we are at all times, Johnny," Frank said. "I designed it myself and I'm off across the pond soon to market it there. I reckon it'll make millions, Mate."

It was all a bit too much to take in at once so I hobbled out into their kitchen to collect my kit and stow it away in one of the many waist-high cupboards of my purpose-built flat.

Frank had disappeared by the time I'd finished and Mo told me he'd gone into town for a business meeting, "He's really excited about the alarm," she said. "I think it's a brilliant invention, the best thing he's ever done."

"Not quite, Mo," I said softly. "Marrying you was the best thing he's ever done."

She blushed prettily and reached up to touch her lips to mine.

"You can't imagine how many sleepless nights you gave me, you big, awkward oaf," she whispered.

I held her tightly and told her that it was the only thing I could think of to get me home to her, but it turned her taps on again and all I could do was hold her tightly.

"Don't go back, Johnny. Please, Darling. I couldn't go through all that again."

"I can't make any promises, Mo. You know that."

"I know," she whispered, "but when I thought I'd lost you--"

We kissed again and I breathed in her aroma. She was my life, my only reason for being and I wanted her more than I'd wanted anything else in my life!

As with most twins we'd always been close. After our parents died in an aeroplane crash we'd grown even closer, even to the point of sharing a bed. We both knew it was wrong but we loved each other; to us it was as simple as that.

We'd never actually made love, although we came extremely close to it on several occasions. The last time being after a drunken party when we'd played forfeits and dares with some friends. She'd been ordered to forfeit her panties and the dare was for me to take them off her.

I did and the other two couples knowing we were brother and sister had been so turned on they'd began fucking each other almost immediately. So, we slipped away home determined that we would finally cross the invisible barrier and make love.

We'd got into bed completely naked but the sight of her sweet little pussy had proved too much for me, I went down on her and manoeuvred myself round so she could take me into her mouth. Unfortunately we were so drunk that we both climaxed almost immediately and fell asleep in each other's arms after promising to consummate our forbidden love the following night.

But the next night I was behind bars charged with assault after yet another drunken brawl and two days later I'd joined the army which had given me a purpose in life. I'd been awarded the sword of honour as the top recruit at the passing out parade.

She'd been there with Frank who in spite of the turmoil within me, I actually liked. They'd married during my first tour of duty in Northern Ireland, which, by then, had quietened down considerably so I saw no action there at all. Indeed I saw nothing until I was sent to Afghanistan were I was promoted to sergeant. Shortly afterwards, I applied for selection to the S.A.S., the toughest and most secretive fighting force anywhere in the world.

Maureen had backed me all the way. After a years training. I passed selection and was awarded the coveted sand coloured beret with the legendary “WHO DARES WINS” logo on the badge.

Next came a series of small covert operations in all four corners of the world. I loved it: the easy comradeship, the secrecy, and the sheer bloody gut wrenching excitement of it all.

A four-man unit had been sent out to Afghanistan, yet again, to capture a much wanted Taliban leader who'd so far managed to evade the green army. We caught up with him and his gang of ruthless cutthroats.

It was during our exfiltration that we were caught in a well-planned cross-fire from two groups of Taliban fighters. Scotty, my corporal and best mate, died instantly, I went down with a couple of heavy rounds in my thigh and a grenade had ripped half my face away. Fortunately our withdrawal chopper had taken care of our attackers and the last thing I remembered was being bundled unceremoniously aboard whilst screaming out for someone to get Scotty's body on board.

I was luxuriating in a lovely warm bath with a can of beer when Maureen knocked on the door and walked in with another can.

"Can I come in?" she smiled. "I've got something to tell you."

I saw her wince as she looked at the red puckered flesh of my thigh. My attention was on her as she handed me the can and took up a flannel to begin dabbing at the wound.

"It's looking better Johnny," she said, then added with a smile, "You seem to be getting better all around." Her eyes were on the dome of my penis sticking up out of the water.

"What have you got to tell me?" I asked, somewhat embarrassed at her gaze.

"What? Oh yes. Frank's going to America tomorrow morning."

"So soon?"

"Yes. His company have been contacted by a manufacturer in America. they want him there as soon as possible to discuss a licence agreement."

She was still dabbing at my wound and my penis was still poking up from the water, but getting even harder if it were possible. With a giggl,e she wiped the flannel over the swollen dome and gasped in astonishment as it erupted. It sent several long strands of semen jetting out into the water. I was mortified and just wanted to bury my head, but she realised just how long I'd been without a woman and spluttered her apologies.

"I should have realised, Johnny," she said miserably as I stood up awkwardly to get out of the bath.

"You weren't to know," I said and wrapped a towel round my waist. "I'm going for a nap now." I left her looking miserably at my back as I walked angrily into the bedroom.

It was the first truly dreamless sleep I'd enjoyed in many weeks and when I finally awoke, I realised that I'd slept right through the night.

I heard voices coming from the kitchen and opened the door to say hello, but the sight of Frank kissing my sister goodbye stopped me in my tracks. I stood there feeling like a voyeur as he stroked her sexy little bottom beneath the raised hem of her short skirt. Her panties were small and pink. I felt an insane surge of jealousy as I watched her squirming under his big hands.

Closing the door again silently, I waited until his car pulled away before walking out into the kitchen again. I yawned as if I'd just woken up.

"Hi, Shorty," I laughed, using my pet name for her. She turned cheerfully to greet me.

"You've just missed Frank. He's gone."

"I know," I said. "I saw you both kissing. You've got a lovely bum, Shorty."

"There's something I should tell you, Johnny."

"Sounds serious." I smiled and reached for the coffee pot.

"No, it's not serious at all. Well, I suppose it depends on how you look at it."

"Try me."

"On the surface I'm a happily married woman."

"On the surface?"

"Yes on the surface, Johnny, but underneath things aren't quite what they seem."

She hesitated and I saw her struggling with her emotions.

"I'm still a virgin, Johnny."

"YOU'RE A WHAT?"

She repeated what she'd said and then the tears came. I stood there like a bloody statue, looking and feeling very stupid until, with an obvious effort, she managed to control her emotions.

"He told me to give you this, Johnny. I know the gist of what he's written, but please don't blame me, Darling." She handed me a letter in a sealed envelope with my name on it. "I'll cook some breakfast while you read it."

"Dear Johnny." it began, "I know exactly how close you and Maureen are and I don't blame either of you. You're both special people. I'm assuming, by now, that she's told you about the lack of sex in our marriage. Please believe me, my friend, when I say that there's nothing I would like more than to consummate our marriage. It can't happen though, Mate. Please don't blame her for telling me about your youthful explorations. I think you'll find it more common than you might think.  Just make her happy, John. Please, my friend. You're her hero.”

Your friend,

Frank"

She was standing at the cooker frying bacon with her back to me and she started slightly as I kissed her neck.

"He's a hell of a man, Mo," I said softly. "But, why can't he do it?"

"He doesn't know Johnny. He thinks it may be as a result of a childhood illness, but although he's seen all the doctors even head shrinks. Nobody knows."

"Turn the bacon off, Mo."

"Eh?"

I reached in front of her and turned the bacon off before taking her into my arms. "I think we should go to bed don't you?"

She touched her lips to mine and I felt her tongue snaking in between them as she whispered softly, "Yes, I think that sounds perfect."

I unfastened her blouse in the bedroom and took each full nipple into my mouth after unhooking her bra and laying her on the bed.

"Johnny," she gasped as I pulled her tiny pink panties down and kissed the glistening wetness of her slit. She arched her back up off the bed and whimpered as I parted her thighs, still keeping my mouth on her sweet little cunt.

"Do it to me Johnny," she hissed. "I need to be fucked now!"

With one hand, I awkwardly unzipped my shorts and kicked them off. My prick was throbbing and rock hard as, finally, I left the tasty wetness of her cunt and moved quickly up her body. Almost of it's own accord, I realised my prick was nudging against the folds of her cunt.

"Yes," she urged me. I pushed forward until a squeal of delight escaped her lips and my prick was enclosed in a warm, velvet glove.

"Oh God, Mo," I gasped as her ankles locked around my back. "I'm inside you, Darling. I'm actually fucking you."

She could only make unintelligible noises as she clung to me, her hands gripping my buttocks, her mouth under mine, her lips apart, and her tongue dueling with mine. Finally, she managed to find her voice and gasped that she was loving it. 

"You're fucking me, Johnny," she gasped. "Oh my God. I can't believe it, Darling. I've got your cock inside me."

I began to move faster and deeper and she matched my thrusts with upward thrusts of her own.

"Johnny, you're going to make me cum, Darling. Do it to me, shag me baby, shove your prick right up me. I'm coming Johnny. Oh, God yes, I'm coming."

Her eyes grew wide and her mouth formed an O followed by a smile of pleasure. Her back arched up off the bed and she used both hands to pull me in as I came with her, filling her with my seed.

We shared a bath then and ate a leisurely breakfast in the garden afterwards. She had to go food shopping and I insisted on going with her. I loved being with her. Her enthusiasm for life was infectious, a welcome change from the harsh cynicism of army life. I limped beside her through all the many shops she visited and wondered why she chose to trek what seemed like miles to save a few coppers on an item of food.

At home she surprised and pleased me by taking her panties off before putting all the grub away. It entailed a lot of lifting and stretching, so of course we had to go to bed again and slake our newly discovered lust.

Frank phoned that evening from New York and she told me he was genuinely pleased when she told him she was no longer a virgin. It seemed rather odd, at the time, since she was licking my penis like a lollipop. After she put the phone down, I pulled her up to face me and said that I needed to tell her the name of the girl who'd taken my virginity.

"Go on then," she giggled as she continued playing with my prick.

"It was you, darling Mo," I said softly and crawled on top of her yet again.
