I could tell immediately that Carol had something on her mind when I got home from work. As we sat sipping our pre-dinner drinks she finally unburdened herself.
"Margaret rang today. She wants to come and stay for a few days. Do you mind?"
"So long as she's not going to go over the circumstances of her divorce yet again," I replied. Margaret was Carol's older sister and she had been involved in a rather acrimonious divorce six months ago.
"No, I think she's over that now," my wife replied. "Actually she's just bought a couple of new dresses which she wants me to alter for her."
"Oh, she's getting ready to put herself about again is she?" I queried.
"'Don't be unkind David she's been through a very tough time."
Actually, I didn't really mind at all. Margaret is a very delectable blonde, a slightly older version of my wife and the prospect of squiring the two of them was rather appealing.
"Actually darling, there is something else," Carol purred in the seductive tone she adopts when she wants me to put myself out. "Her car's broken down. Would you be an absolute dear and pick her up?"
"Why can't she come on the train?" I asked.
"I told you, she's bringing a couple of dresses for alteration and she doesn't want to crumple them up in a suitcase."

A few days later I found myself driving down the motorway with my sister-in-law sitting beside me and her dresses spread out on the back seat. We chatted for a while and then she reclined her seat and closed her eyes. Like many a man, I suspect, I have occasionally indulged in speculative fantasies about my sister-in-law's sex life. It has never progressed beyond an occasional brotherly kiss and cuddle but I confess to having sometimes contemplated the possibility of going further, particularly now that she was divorced. She shifted in her seat and crossed her legs revealing a seductive flash of thigh and stocking top. It almost felt like she was lying in bed next to me. I drove steadily on, sneaking occasional glances at her thighs. Her breasts moved gently beneath her clothing as she breathed in and out. My growing erection was beginning to make my crotch feel rather uncomfortable. I cautiously unzipped my flies and manoeuvred my cock into a more comfortable position so that it could expand more readily. As I did so Margaret suddenly opened her eyes. I hastily zipped up and put my hand back on the steering wheel but the bulge in my trousers must have been obvious. She glanced at me, moved her seat back into the upright position and adjusted her dress.
"I'm glad to see you don't wear those awful tights; they are real passion killers," I said, trying to diffuse the mutual embarrassment.
"You're supposed to be driving, not looking at my legs," she smiled, but it was clear that she was not displeased by my attention.
That evening after much sisterly chat over dinner, Margaret produced her new dresses for Carol's expert attention while I retired behind a newspaper. At some stage Margaret left the room to put on one of her dresses. When she returned; Carol busied her self with pins and tape measure. Eventually they were both satisfied.
"OK Margaret you can take the dress off now, I'll sew it up in the morning."
Quite forgetting that I was sitting there Margaret removed her dress giving me a delightful view of her lingerie before leaving the room to dress again.
Later that night, in bed, I snuggled up close to my wife.
"I see your sister keeps herself in very good shape," I whispered.
"Yes, I noticed you eyeing her up and I assume that's what's giving you an erection now!" Carol allowed me to remove her nightdress.
"But it's you I'm going to fuck isn't it? I murmured as I fondled her breasts.
"Well, no actually, I'm going to fuck you," she said decisively, as she flung back the bedclothes and straddled me.
Her movements as she wriggled herself into position before lowering herself onto my cock were a delight to watch. As she rode up and down I squeezed and kissed her tits. Soon she was gasping and sighing as I felt the tell tale spasms in her vagina which was the signal for me to erupt with orgasmic pleasure.
Next morning I woke early and went downstairs to make an early morning cup of tea for everyone. After taking a cup to Carol I knocked on Margaret's door and silently entered the room. She was half awake and as I approached she pushed herself into a sitting position which had the unexpected but delightful effect of pulling her nightdress off her shoulders and thus revealing rather more of her breasts than I would normally expect to see.
"Good morning Margaret, what a very stimulating sight," I joked, kissing her gently on the cheek.
It required a superhuman effort on my part to refrain from touching her breasts before she casually slipped them back inside her nightdress. I sat on the side of the bed and watched her sipping her tea and wondered if she was aware of the growing erection under my robe. She smiled and very casually placed her hand over the evident bulge.
"I think your John Thomas is in need of a little exercise isn't he?"
I leaned forward and kissed her on the lips and at the same time began to gently fondle her breasts through her nightdress. Her hand slid inside my robe and gently caressed my cock. I pulled aside the bedclothes and began to slide my hand up her legs.
"No David!" she ordered firmly and quickly released my excited member.
"OK" I conceded, "but please let me have another look at your beautiful tits." She pulled the bedclothes back up.
"Alright, but only look, don't touch," she instructed. I nodded in agreement.
As I watched she slipped her arms out of her nightdress and pulled it down so that her breasts were fully exposed. I exclaimed with a mixture of admiration and lust. The size, variety and shape of women's breasts are a constant source of wonderment and delight to me. I allowed my dressing gown to fall open so that she could see the extent of my arousal.
"My cock really does need a workout now." I pleaded. She smiled impishly.
"I suppose I can't really send you back to Carol like that can I? Hand me that jar of hand cream on the dressing table." I did as I was asked and watched as she unscrewed the jar and scooped out liberal portion of lotion.
"Come a bit closer and don't say a word," she whispered.
Delicately she applied the cream to my cock which was so stiff it hurt. Margaret may have been divorced for some time but she hadn't forgotten how to play with a man's sexual organ. I sighed with pleasure as she alternately squeezed and rubbed my member. Neither of us spoke but it was utter bliss for me as she deftly and expertly tossed me off. It took only a few seconds for me to reach climax. Gasping with pleasure I ejaculated all over her breasts. She release hold of me and looked down at the semen trickling down her breasts.
"I'd quite forgotten what messy creatures you men are," she said, as she wiped her hands on my robe.
"Perhaps you would like me to remind you what it feels like to be fucked by a man?" I suggested softly.
"I think you'd better go before Carol starts wondering where you are," Margaret said. She got out of bed with her sticky breasts still exposed.
"OK, I'll go; but can I see you naked?" I ventured, more in hope than expectation.
Margaret sighed and allowed her nightdress to fall to the floor. I stared in amazement. Although she was the wrong side of forty she still had a magnificent well proportioned body which began to cause lustful stirrings in my loins again.
"Now David darling, please fuck off," she commanded, "I want to take a shower."
Reluctantly I fastened my robe and returned to our bedroom. Fortunately Carol had dozed off to sleep again and she didn't stir when I slipped into bed beside her.
Later that morning after breakfast the girls took themselves off to London for some shopping. When they returned in the early evening I detected a subtle change in the atmosphere. I had the feeling they were up to something. Eventually I dismissed it as just girly things and sisterly secrets. I could see from their various bags that they had been buying lingerie, very expensive lingerie; not the cheap tarty type that I normally buy; ostensibly for Carol, but actually for my own personal gratification and stimulation.
Later we went out for a meal at the local pub which was a short stroll down the road. The talk turned to their shopping spree and I enquired if they were going to model their purchases for me. This provoked a bout of whispering and giggling from the two of them. We returned home in a very relaxed state as a consequence of the substantial amount of wine we had consumed.
For some reason Carol decided she needed to work on Margaret's second dress. This time I just sat in my chair and watched as the dress was tweaked and adjusted until both sisters were satisfied. When the time came for Margaret to remove her dress Carol asked her to wait while she got out her sewing machine to complete the job. Margaret sat in her chair in her underwear while Carol sewed away. Without any pretence I stared directly at her taking in the delightful contours of her body. Our eyes met and she instantly read the lust in my gaze. She got up and sauntered over to watch Carol at work giving me a very provocative view of her rear. Soon the sewing was complete and she slipped the dress on once more. My opinion was canvassed and I naturally assured them the dress was perfect.
"You must be the same size as Margaret, why don't you try on the dress?" I suggested to Carol.
Having seen Margaret naked that morning I was quite sure of their similarity. The girls needed no further encouragement and during the hiatus both sisters were briefly standing there in their underwear before Carol assumed the dress.
"
"Well, what do you think?" Carol asked. There was a short pause.
"Actually," I said. "I think you both look much better in your underwear."
There was general laughter at my risqué remark.
