I had met Carol once before, though only briefly.  I remembered her as being tall, slender, and blonde, with deliciously large breasts... much larger than Mary's.  My memory hadn't failed me.  As we stood chatting in the living room I had to make a concerted effort not to embarrass myself by stealing glances down at Carol's chest, though I wanted to desperately.  She was dressed quite properly, in tight fitting slacks and a red blouse that dipped tantalizingly low in front.  I had the impression that Carol wasn't wearing a bra (were those hints of her nipples I could see through her blouse?) but I didn't dare look hard enough to determine for sure.

"I'm so glad you were able to come," Carol told me as we stood chatting.  "Mary's told me so much about you, and I've been hoping to get a chance to know you.  Last time we hardly had any time at all!"

Carol was smiling as if with amusement, and I got the distinct impression that she knew just how badly I wanted to study her breasts.  When she turned away for a moment, and I was sure Mary wasn't looking, I did steal a glance down at Carol's chest.  My cock swelled.  She was definitely braless under her blouse.  I couldn't help but look lower, my eyes playing down her body.  Carol was so much slimmer than Mary, her hips so much more shapely, her legs so much longer.  As desperately as I wanted to be with my sister, Carol also aroused in me a primal lust.

"I'm going to go unpack," I said hoarsely, tearing my eyes off Carol before I could embarrass myself.  I left Mary and Carol in the living room and retreated to the guest bedroom, hoping Carol wouldn't notice my bulging crotch as I went.

Alone in the bedroom, I stopped and breathed a sigh, willing my pulse to calm.  Two beautiful women, one of them my sister.  I wanted to fuck them both, and in my mind I did, playing scenario after quick scenario.  Mary and I together... Carol and I... the three of us...

I pushed the thoughts from my mind and turned to my task, unpacking.  I hung my clothes in the closet and put my toiletries in the bathroom.  There was no sense in living out of my suitcase after all, even if it was only for the weekend.

Mary's stockings still lay discarded on the bed where we had forgotten them in our rush.  I gathered them up and started to set them aside, then paused.  I couldn't help but bring them to my nose and smell them.  They smelled faintly of Mary, of her sweet, alluring perfume.  On an impulse I stuffed the stockings into my suitcase, tucking them in deep where they wouldn't be found.  I would take them as a memento our all-too-brief moment together on the bed, even if I hadn't gotten to do half the things I had in mind.  But then, we still had the whole weekend ahead of us...

When I was unpacked, and sure I could keep my hormones in check, I went in search of Mary and Carol again.  They were no longer in the living room.  I was about to check the den when I heard sounds from the kitchen.  I moved to the doorway and hesitated, taken aback by what I saw.  Mary and Carol were in the kitchen alright... arms around each other and deep in a passionate kiss!

  I stood watching in shock, my heart pounding.  As they kissed Carol snuck one hand lower to my sister's bottom, an intimate movement obviously borne of familiarity.  After a long, long moment they reluctantly parted lips.

"Your brother's cute," Carol told my sister softly.  I felt a stab of excitement at her words.  That Carol might find me attractive had never crossed my mind.  Carol smiled at Mary and leaned closer as she continued: "I bet you'd like to fuck him, wouldn't you?"

I felt faint.  Mary had told Carol about us!?  As I stood watching, Mary nodded meekly.  "You know I would, Carol." 

Carol smiled with obvious amusement.  "If you ask me nicely Mary, maybe I'll let you."

My sister looked at Carol pleadingly, her cheeks flushed.  "Please Carol... can I?"

Carol chuckled.  "You can do better than that, Mary.  Beg me properly."

"Carol, please!"  Mary's voice was quiet, almost a whisper.  "Please, won't you... won't you let me fuck my brother!  I... I need it so badly, Carol.  You know I do.  Please, it's been so long.!"

I was beside myself listening to my sister beg for permission to fuck me.  Carol seemed to enjoy it as well.  She leaned forward and kissed Mary again on her lips.  "Perhaps," she said teasingly.  "Perhaps... if you're good."

"I'll be good," Mary assured her quietly.  "Please Carol, I'll be good."

"Well, we'll see about that..."  Carol sounded amused, as if she knew perfectly well that Mary hadn't been good, that we had already been naughty together.  But if she did suspect it, Carol didn't say anything.  She played with Mary's short, blonde tresses for a moment, then turned and disappeared from the kitchen into the den.  A moment later I heard the television come on.

Mary remained standing with her back to me, as if still basking in the kiss.  I watched her for a moment and then moved into the kitchen and joined her without a word.  Mary looked up and blushed beet red when she saw me, as if she knew without my saying so that I had witnessed her intimacy with Carol.

"Brian, I--"

I kissed Mary quickly, before she could complete her thought.  It felt strangely erotic, kissing her so soon after Carol had.  I imagined I could taste Carol on her lips, thought it was probably just my imagination.

After a moment I started to pull away, but Mary put her hands behind my head and held me in the kiss.  Her eyes drooped shut, and before I knew it she was kissing me as eagerly as I had begun kissing her.  I slipped my arms around her waist and pulled her body tightly against mine, forgetting for a moment how exposed we were there in the kitchen with Carol so near.

When finally our lips parted, Mary smiled at me.  "Thank you, Brian," she whispered.

"For what?"

"For not judging me."

I was quiet for a moment.  "I do judge you, Mary."

"You do?"

"Yes.  I judge you to be a beautiful, sexy woman... even if you are my sister."

Mary smiled.  "You're sweet, Brian."

"No, I'm horny!"

We both laughed, but it was a nervous laugh.  We both knew what the next step was, the next intimacy, but it was so risky... especially with Carol watching TV in the next room.  Our predicament reminded me of another time with Mary during our youth.  One night Mary had been feeling particularly adventurous and we had ended up fooling around in the kitchen with our parents in the next room watching TV, just as Carol was now.  I smiled, remembering how exciting that evening had been, how close we had come to being caught.

"Do you remember--"

"--that time in the kitchen?" Mary finished my sentence with a smile.  She did remember.  That night I had watched my sister pleasure herself in the kitchen with a cucumber.  We had never come closer to being caught than that time.  We'd only been seconds away...

"I want you to fuck me, Brian," Mary said suddenly.

I wasn't sure what to say.  I wanted it too; needed it, desperately.  "Right now?" I asked.  "Right here?"

Mary laughed.  "No, not here and now... but soon.  God, I've wanted it so long Brian...."

"Me too," I assured her.  I'd been thinking about it for years.

"Do you know how long it's been since I've had a man inside me?"  Mary's voice was soft and timid.  I didn't know.  In my fantasies I often imagined I was the only one she'd been with, but I knew that wasn't true.  Mary hadn't always been into women, and even now I suspected that she wasn't so staunch a lesbian that she would forgo a good fuck.  I shook my head.

"Six months," Mary said softly.

I was stunned.  "Six months!?"  God, she must need this more than I did!

"Maybe longer..."  She was blushing now.

"Why so long?" I asked quietly.

"Carol doesn't let me be with anyone without permission."  Mary's voice was barely more than a whisper now.  "Especially men..."

"But so long!?"  I could see the embarrassment in Mary's eyes for having admitted this to me, and at the same time the obvious yearning she had.  I could tell she needed desperately to be fucked.  And I wanted desperately to be the one to do it... but not there in the kitchen.  Not with Carol in the next room, liable to walk in on us at any moment.  With a smile I playfully, teasingly suggested the next best thing.  "Do you have any cucumbers?"

I said it as much as a joke as anything, but when Mary's eyes lit up I knew I had struck a chord with her.  "I... I think there's one in the refrigerator," she offered quietly.

I hesitated.  We couldn't do this... could we?  With Carol in the next room?  But the hopeful look in Mary's eyes aroused me.  I couldn't help but move to the refrigerator.  She was right; there was a cucumber inside.  Three in fact, of varying sizes.

I chose the middle sized cucumber and turned back to Mary.  She was standing timidly, watching me with a mixture of excitement and unease.  We both stood facing each other for a moment, unsure how to take the next step.  After this, nothing would be the same.  We weren't kids any more.  We wouldn't be able to use youth as an excuse.

"Turn around," I told Mary quietly after a moment.  As she turned away from me to face the counter I set the cucumber aside and moved close behind her.  Her dress zipped down the back, and now I unzipped it slowly from her neck down almost to her bottom, the silky material sagging open to reveal her sexy, pale backside.  Oh, how long it had been since I had seen that sweet skin!  I slipped my hands inside Mary's dress from behind, reaching around to cup her breasts under the light fabric.  She wore a lacy bra, black I could see by the strap, matching her panties.  I gently tweaked her nipples through the thin material and immediately Mary groaned softly.

"Mmm..."

I pinched harder and Mary stiffened.  As I pinched and twisted her right nipple, I withdrew my other arm from under her dress and carefully undid the hook on her bra.  As her bra came undone Mary gasped and moved her hands to her breasts in defense.

"Brian, not here!" she hissed.  "Carol could walk in!"

"I don't care," I told Mary quietly.  I didn't, not any more.  I wasn't thinking, or at least not with my head.  I slipped my other arm out from beneath her dress and coaxed Mary to lower her hands.  She did, reluctantly.  As she stood trembling I slipped her dress off her shoulders from behind and let it slip down.  It caught briefly on Mary's modest breasts, but before I could help it along she shimmied ever so slightly and it dropped to the floor, pooling silently around her ankles.

I hesitated for a moment, aroused by the sight of my sister standing almost naked wearing only her sexy panties and partly-undone bra.  Eager now, I coaxed her bra off and let it, too, fall to the floor.  Unable to help myself, I reached around and cupped my sister's bare breasts.  They were so perfectly shaped, so sensual and firm.  Not too small, not too big... just right.  I pinched her nipples lightly, then harder, then very hard... hard enough that Mary gasped and cringed in my arms.  She had such deliciously large, sensitive nipples.  As I continued tweaking her nipples she leaned her head back on my shoulder and sighed.

"Oh God Brian..."

I kissed her gently on the base of her neck and gave her nipples a final, quick pinch.  Then I knelt down behind her, kissing my way down her naked backside as I went.  Mary wore one last item of clothing: her sexy black lace panties.  As I began to tug them down, the TV fell silent in the other room.  I froze, my heart skipping a beat.  Carol!  But before I could panic the sound of the TV came again.  Mary and I both breathed a sigh of relief.  Carol was just changing channels.

I slipped Mary's panties down without a word and helped her step out of them.  She was naked now, completely and uninhibitedly naked.  I rose and played my fingers over her backside.  So smooth, so soft.  So sexy...

Mary started to turn but I stopped her.  "Put your hands behind your back," I told her quietly.  I had one more thing in mind.

"Why?"

"Just do it," I insisted quietly.  Mary hesitated, then moved her hands behind her back.  As she held them there for me I slipped her panties over her wrists and drew the lacy fabric tight, knotting it together so it bound her wrists securely.  Almost immediately Mary tugged at her binding, but to no avail.  I had tied her wrists securely and now she was helpless.

"Brian..."

"Like it?" I asked quietly.

"I..."  Mary hesitated.  "I love it," she said quietly.

"I could gag you, too," I suggested quietly.

"No Brian, please don't."

I wasn't sure if Mary was serious or just playfully resisting, but I was just teasing anyway.  I wanted to hear my sister's voice, hear her moans.  "Turn around, Mary."

She turned around with a sheepish smile and stood before me naked.  I stood frozen, captivated by my sister's beauty.  It had been so many years since I had seen her like this, without any clothes.  I stiffened immediately.  Mary still looked so sexy, so alluring, even after all this time.  With her arms bound behind her back she looked so wonderfully, temptingly helpless.  I moved close and played my fingers over her breasts, then down to her belly and lower, to her thighs, tracing the faint wrinkles in her skin that hadn't been there the last time we were together.  Mary had aged so gracefully and now, if it was possible, I found her even more attractive than she'd been all those years ago.  Especially her shaved pussy.  Her labia looked so plump and inviting, peeking out nakedly from between her thighs.  I just had to see her penetrated, hear the sigh of contentment that I remembered from so long ago.  My heart racing, I reached for the cucumber.

"Warm it first, please Brian?"  Mary's voice was timid and excited.

I warmed the cucumber under hot water.  My mind raced.  In the next room the TV played softly.  I prayed we would be able to hear Carol if she got up.

There was a bottle of hand lotion by the sink.  Not a perfect choice, but it would have to do.  I coated the cucumber generously, spreading the lotion with my fingers.  As I did this I knelt in front of Mary and leaned forward to kiss her belly, then lower just above her shaven mound.  When I felt the cucumber was slick enough I brought it up and positioned it between her thighs.

"Be gentle, Brian... please?"

I wouldn't have it any other way.  I nudged the thickly rounded end of the cucumber between Mary's folds and searched for her opening, pressing upward gently.  It took a moment before I got the angle right, but when I did the cucumber sank in an inch and Mary stiffened and gasped.

"Oh God!"

Mary was tight, even after all these years.  I pressed the cucumber up into her pussy slowly, at the same time leaning forward and taking her hooded clit between my lips.  As I began to suck on her little bud Mary put her hands on the back of my head and gripped me tightly.

"Oh Brian, that feels so nice!"

I smiled and flicked my sister's clit with my tongue, at the same time pressing more firmly on the cucumber.  We'd reached a thicker part of the vegetable and now Mary gasped as it sank more slowly into her tightness.  I stopped pushing and let her muscles ease the cucumber out an inch or so, and then I pressed it back in, sucking her clit at the same time.  This time the cucumber went in a couple inches and Mary groaned softly.

"Quiet, Mary," I reminded her.  The TV still played in the next room, providing cover for our stolen moment... but just barely.  All we needed was for Mary to groan loudly and give us away.

"I... I'll try, Brian, but--"

I gently nipped at Mary's hooded clit with my teeth and she gasped, her train of thought disrupted.  I pushed the cucumber into her pussy more firmly and it sank in another couple inches.  Mary's pussy tightened again, and again I let her muscles push the cucumber out slightly.  Now I began fucking her slowly with the cucumber, making shallow, steady motions in her pussy.  As I teased her like this her pussy loosened and accepted the cucumber deeper, her natural lubrication now aiding the hand lotion on the thick green shaft.  Emboldened and aroused, I stroked the cucumber into her pussy more boldly, matching the motions with a firm sucking on her clit.

For the longest time the only sounds in the kitchen were Mary's soft moaning, the wet sucking sounds of the cucumber as I fucked her with it, and the sound of the TV coming from the next room.  I nibbled and teased Mary's clit, working the cucumber with one hand and reaching up with the other to pinch her nipples.  This drove her wild, just like it had so many years ago.  Mary began squirming, and when I looked up I could see she was biting her lip, trying to keep from making noise.  I smiled.  She was close...

"Oh God Brian, just like that.  Keep doing that.  Just a little more--"

"Brian!"

Mary and I both froze as Carol's sharp voice rang through the kitchen.  I felt Mary tense in my arms, heard her shocked gasp of dismay.  With the cucumber still half buried in my sister's pussy I turned around with dread and felt my heart sink.  Carol stood in the doorway, her hands on her hips, watching us with a stern look.  She didn't look happy...
