I scowled across the table at my wife as she flirted with Gordon, my younger sister's husband, I had a nagging suspicion that Gordon and Claire, my wife, were having an affair and although my relationship with Claire was not that good I did object to the idea of being cuckolded. Then again it could all be the fevered imagination of a thirty year old man suddenly aware of his own mortality, Lucy, my sister, leant across the table to say something to Claire and I saw a flicker of annoyance in my wife's eyes and I knew that I wasn't imagining things. Looking at Lucy I wondered if she knew what was going on, my little sister had always been a bit naive about people, especially Gordon who had charmed her into the wedding bed long before the wedding. None of the family had approved of Gordon, but after five years of marriage I had to admit he had stayed with Lucy though I had no doubt he'd had a number of flings in that time, Claire being the latest of them, or so I guessed, the fact was I had no proof, just a gut feeling. Lucy was smiling at me and I marvelled at how beautiful a woman she had become after her spotty, buck-toothed childhood, at twenty-five she had everything a man could want which made Gordon's philandering incomprehensible.

"You're quiet tonight Gary." my sister smiled.

"Hmm," I replied dragging my mind back to the present, "oh, sorry, I was miles away then."

"I said you're quiet tonight." Lucy repeated herself.

Her smile looked a little strained to me and I wondered if she was at last seeing Gordon for what he really was, but I kept my thoughts to myself as I replied.

"I've just got a few things on my mind." I said glancing at Claire.

Lucy's eyes flickered in the direction I was looking then came back to me, she sighed then smiled.

"Gordon's taking Claire to Ascot tomorrow," Lucy said with a hint of annoyance in her voice, "would you like to come over and keep me company?"

"I'd love to." I replied, as I wondered why Claire hadn't mentioned it to me.

"It's a date then." Lucy smiled almost sadly, "I'll see you at ten or will that be too early."

"Ten is fine," I replied, "put some wine on ice and we'll make a real day of it."

Later that night I asked my wife about her 'trip' to Ascot with Gordon, we ended up having a steaming row which ended with her storming off to bed while I fumed quietly in the living room. There was a man I knew who had contacts with a detective agency and I called him then and there, thankfully my friend didn't keep office hours and was only too pleased to make the arrangements to have Claire and Gordon watched. When I hung up the phone I felt a little guilty for not trusting my wife, but my guts were telling me there was something going on and I had always been one to follow my instincts, they'd seldom let me down in the past and I didn't think they were wrong now. Pouring myself a stiff drink I sat and brooded about what had gone wrong in my marriage of ten years standing, I suppose it had all gone wrong when Claire had miscarried three years back, thinking back on it I should have guessed something was wrong even then for later tests had shown that I was totally sterile, the equipment worked, but I was firing blanks. This made me wonder how many other lovers Claire had been with since we had got married, by the time I went up to bed I was feeling more depressed than angry and to find that Claire had locked the bedroom door was the last straw. I decided that if it was proved that she was having an affair with Gordon I would divorce her, the way the laws were now I would not lose much once it was proved she was an adulteress, but I felt sorry for Lucy, she didn't deserve this added problem.

Promptly at ten the next day I arrived at my sister's home, she opened the door looking pale and red-eyed as though she'd been crying, nevertheless she gave me a smile as she ushered me into the living room.

"What's wrong Lucy?" I asked as I sat down on the couch.

It was like opening a floodgate, she flopped onto the couch beside me, leant her head on my shoulder and sobbed her heart out, and in between sobs she haltingly told me about all the affairs her husband had had since their marriage.

"I can't turn a blind eye to it anymore," she said at last straightening up, "he's hardly ever home anymore and when he is he's too tired to want to do anything. This latest affair with Claire...Oh!"

"It's all right Lucy," I grinned at her gasp of horror at letting it slip that my wife was having an affair with her husband, "I had an idea of what was happening anyway, in fact just last night I set a detective agency on them, once I have the proof I'm divorcing Claire."

"If you get the proof," Lucy declared, "I'll divorce Gordon too. God how could I have been so stupid for all this time."

"Because you always see the best in people," I grinned, "I haven't figured out my excuse though."

"Because you're too nice Gary." my sister laughed.

It was as though a load had suddenly been lifted from our shoulders, with a grin Lucy stood up and declared that she was going to 'freshen up' while I poured the chilled wine I'd find in the fridge. Sure enough there was a bottle of white wine in the fridge and I poured us both a large glassful which I carried through to the living room, about ten minutes later Lucy joined me again, she'd certainly freshened herself up though she still had a little redness around the eyes, but on the whole she looked stunning and I said so.

"Flatterer," she grinned as she took her glass from me, "I don't remember you complimenting me when we were younger."

"You weren't such a gorgeous thing when we were younger." I laughed.

"I know," she laughed, "God I was a sight back then and you always used to tease me about my spots and my teeth."

"I can't tease you now though," I grinned, "if I had you tied up now like I did all those years ago I'd not be tickling you that's for sure."

I was referring to an incident when I was fifteen and Lucy was ten, we'd been mucking around and I'd pretended to be an red Indian and tied her to the washing line post, I'd tickled her until she was sobbing. As I remembered the incident fondly I noticed Lucy give a little shiver, raising an eyebrow at her I asked her if anything was wrong.

"I was remembering that day," she grinned, "you were a right sod back then and you never knew how wet you made me when you tied me up."

She sighed wistfully at the memory, and then grinned.

"I've fancied you ever since that day." she admitted with a laugh.

"Lucy!" I said in surprise.

"Have I shocked you?" she grinned, "I'm sorry Gary, but ever since that day I can't see a rope without getting a wet pussy."

It was more of a surprise than a shock really, to be honest I had fancied Lucy ever since she had grown into a beautiful woman, only a thin line had prevented me from ever telling her how I felt about her, in that respect Lucy had more guts than I.

"I'm sorry Gary," Lucy said mistaking my silence for disapproval, "I shouldn't have said that. Lord what an idiot I am!"

"Not at all," I grinned, "I was just thinking that you were braver than I am."

"Why's that?" she asked with a puzzled frown.

"At least you could admit how you felt." I sighed.

"You mean...?" she breathed after a long silence.

"I mean I've had the hots for you ever since you were seventeen." I grinned wryly, "Only I've never had the guts to admit it until now."

"Are we crazy?" Lucy asked with a smile, "I should be locked up for what I'm thinking right now."

"Maybe we are crazy," I grinned, "but I think they'll lock me up in the next cell."

Draining my glass in two quick gulps I looked at my sister, she grinned and finished her drink, I felt like a foolish kid on his first date, unsure of how I should act, what I should say or do.

"This is silly!" Lucy laughed suddenly, "We're both adults and we know what we want."
