The Houseguest

He tests the limits of his sister-in-law's control.
I love laundry day. Sure, it’s an easy job, as far as housework goes, and I have the uncanny ability of making a few loads seem like I’ve cleaned the whole house. Although the smirk my wife gives me every time I declare the family’s clothes to be clean makes me think she might be onto me. But more than anything, it’s the perfect excuse to get my hands on my sister-in-law's dirty panties.

Last Saturday began the same way as all the others of late. My wife, Liz, had taken our twelve year old daughter to her weekly netball game, yet again losing the battle with Natalie to take her across the Harbour to North Sydney on the ferry. I tried to reassure Liz that it was in fact the quickest way when she kissed me goodbye, but she wasn’t having any of it.

“Your daughter,” she scowled in mock accusation as she stabbed her finger into my chest on the way out the door.

I smacked her ass playfully in reply, eliciting a giggle, and wished Natalie good luck with her game as I watched them walk out to the street.

Then I felt Julie’s shoulder push into my back, and her breast press against my arm as she sidled up beside me. “Good luck, kiddo! Knock ‘em dead,” Julie called after them from the doorway as they made their way down to the Balmain pier.

Julie gave me a quick smile, her deep blue eyes twinkling, and the smell of peanut butter on her breath. She touched my arm affectionately, then padded up the stairs. Her perfect heart-shaped ass rose before me, firmly clad in pink and purple striped pyjama bottoms. I shook myself free of the vision, locking the front door and returning to the kitchen to finish my breakfast.

The sound of running water and other assorted feminine beauty rituals wafted down from upstairs as I tidied up the dishes, and tried to keep my thoughts out of the gutter. My wife's little sister was such a beautiful woman, and it was driving me to distraction. She had been staying with us for two months now, following her divorce.

I turned to see that she had pulled up a stool and was watching me bustle around. Her head was tilted slightly, with her long, sandy blonde hair falling over her shoulder. I snorted a laugh at her t-shirt. It was the light grey one with a Storm Trooper holding a tissue, and the words, ‘I had friends on that Death Star.’

“You like it?” she smiled, sitting up and pushing out her ample chest.

My voice caught slightly, but I managed to croak out a response, before putting much more attention than was required into the coffee machine. “Do you want one?”

“No, thanks. I just brushed my teeth.” She wrinkled her nose at the thought, then tapped the book that lay face down on the bench. “I’m just going to read for a bit outside.”

“Oh, okay. What are you reading?”

Julie didn’t answer. Instead, she just grinned at me, sliding the book off the bench and holding it close across her stomach as she skipped out onto the patio.

“Okay then,” I said to myself, a little confused.

I savoured the taste of the coffee, and the anticipation of the prize that awaited me upstairs in Julie’s dirty clothes basket. When I had waited as long as I dared, I went upstairs to the guest room.

I scooped up her scattered clothes from the carpet, where she had stepped out of them the night before. Thirty-one years old and she still behaved like a teenager, I smiled to myself. Kicking her shoes under the bed and flicking the lid off the hamper in the corner, I dropped in the bundle, then stretched for the plain white t-shirt just out of reach. Then I saw them, a pair of tiny lavender panties up against the bedside table.

Sitting on the bed, I bent down to pick them up. The softness of the satin instantly tingled my fingertips. I held them out in front of me, studying the cute little bow on the front of the waistband, and the frilly, lace embellishments down either side of the gusset. The ‘10’ on the tag, I’m ashamed to say, offered a much more seductive thrill than the size sixteen Liz had become in her mid-forties.

I exhaled slowly to try and calm my heartbeat. Then, turning them inside out, I held the crotch to my nose and mouth, and breathed in her scent. The hint of perfume combined with the earthy aroma of her sex brought me an indescribable relief.

I’m such a scoundrel , I silently confessed to myself, before deeply inhaling again.

I balled up her panties in my pocket and took the whole basket downstairs to the laundry. Sorting the load into lights and darks, I sniffed at each pair as I went, but none of the intoxicating delicates were quite as fresh as the lavenders I had in my pocket.

I got Julie’s lights on first, frowning as the old plumbing in our Balmain terrace hissed and shuddered with exertion to fill the washing machine. Then fishing her panties from my pocket, I took another long, comforting sniff. When I opened my eyes, I noticed Julie out through the window.

Illuminated by the sunlight, she was sitting on the far side of the table from the kitchen door, reading with her feet up on the chair beside her. But from my vantage point at the small laundry window, my view of Julie was unobstructed by outdoor furniture.

From that angle, I could see the cover of the novel. I chuckled to myself as I read the title, Fifty Shades of Grey. Her sister had been right into it herself, ploughing through all three books in record time. It had certainly sparked up our sex life, I remembered fondly.

This sexy little acorn apparently didn’t fall far from the tree.

With my forbidden secret safely back in my pocket, I watched her. She was engrossed in her book, turning the pages every minute or so with considerable urgency. I noticed her lick her lips and swallow, her lips shiny and coming to rest slightly parted. A pinkish hue too, began to spread across her cheeks and neck.

I focussed on the deepening rise and fall of her chest as she read, and I flushed with warmth as I caught sight of her nipples hardening beneath that Star Wars t-shirt. I began to grow hard myself, my cock straining against my jeans.

Julie pulled her sunglasses down her nose, then looked over the top of the rims into the kitchen. I stepped out of view as she swivelled her head back towards the laundry, and counted to ten before poking my head back around the window frame. Craning her head up to look at the windows above her, and obviously not seeing me, she pushed her glasses back up and sank back into her chair.

She rubbed her bottom lip with the tip of her index finger as she resumed reading, then began slowly tracing a path over her chin and down her throat. When her finger found her nipple, mine once again found the lavender satin. I breathed her in as she circled the proud point atop her breast, then pinched the engorged nub with a twist through her t-shirt. The sensation caused her to bite her bottom lip.

As Julie repeated the process with her other breast, I released my aching cock from my jeans and began to stroke. The slimy pre-cum already at the tip provided half the lubrication I needed. I licked my palm for the rest and began pumping my fist up and down my shaft.

Watching her tease her nipples while smelling her feminine musk, I was lost.

Her finger continued its journey down her stomach, no doubt an imaginary substitute for the riding crop I guessed she was reading about at that very moment. I held my breath as her fingers approached the hem of her t-shirt. My own hand was frozen in a tight grip around the head of my cock.

Time stood still as Julie, excruciatingly slowly, lifted her hand from her waist to turn the page. She turned her head to check again that I wasn’t watching her from the kitchen, and satisfied I wasn’t, she licked her lips once more before returning her right hand to its task.

“Oh my God,” I actually heard myself gasp in response to Julie’s fingers burrowing beneath the waistband of her pyjama bottoms.

The pink and purple striped fabric bulged across the back of her hand between her legs as she masturbated in the relative privacy of our backyard. I resumed my own strokes, keeping in time with the tiny, twitching motions inside Julie’s pyjamas. But I was quickly losing control.

Taking one last, splendid whiff of her underwear, I wrapped the precious garment around my cock. The silky smooth sensation of Julie’s panties sliding up and down the full length of my hardness was too much.

I erupted in spurt after groaning spurt of thick cum into those lovely lavender panties. I actually had to brace myself against the vibrating washing machine to keep from buckling at the knees. Squeezing the swollen, sensitive head of my cock, I milked every last drop of semen into them.

Folding my cum into her underwear, I lifted the lid of the washing machine and threw them in with the rest of the load. I took a minute to slow my breathing as I zipped myself up and looked out through the window at Julie on the patio.

Her hand was a lot deeper inside her pyjamas, and the way the pink and purple stripes were bouncing, I could tell she was fingering herself. Julie threw her head back, biting her bottom lip. The delicious squirm of her whole body told me she was close.

It was then that the idea struck me. I smiled wickedly at the thought.

I strode out into the kitchen and threw open the sliding door to the patio. I was two steps outside before Julie noticed me, her soft moan of pleasure twisting into a shocked gasp.

I drifted around the table, keeping my eyes locked on the dark lenses of her sunglasses and delighting in the crimson flush of Julie’s cheeks. She subtly slipped her hand from her pyjama pants, masking the move by laying the book on her lap. It was all I could do to keep a straight face.

I lifted Julie’s feet from the chair and sat, placing them back down across my lap. Ratcheting up the tension by remaining silent, I revelled in the effort she was making to control her heavy breathing. I couldn’t help but smirk. The sunlight caught the sheen on her fingers, glinting slightly as she dried her slender digits discretely on the outside of her thigh.

“Good book?” I teased, knowing I had denied her the release she was so close to achieving.

Julie wet her lips before breathing an incredibly tortured, “Uh-huh.”

“Hmmm,” I smiled. I was far too pleased with myself.

We chatted a while in the garden, screened off from the neighbours by the lilly pilly hedges running down either fence line. I caressed her shins through her thin cotton pyjamas, gently kneading the firm flesh of her calves. Her embarrassment eventually faded, but I noticed when I started rubbing her feet, she blushed again. I petted her knee to let me up, and she lifted her feet. As I went inside, I caught Julie’s reflection in the sliding door. She was watching me walk away over the rim of her sunglasses, her brow furrowed in a bemused frown.

For the rest of the morning, I took great delight in making sure Julie never had an opportunity to finish what she started. Every few minutes or so, I would reappear, offering her a drink, striking up a conversation, or just lingering by the patio doors. I even interrupted her retreat to her bedroom to return her fresh laundry.

It wasn’t long before Liz and a victorious Natalie returned home for lunch, unwittingly joining me in Julie’s torment and giving us both a thorough play-by-play debriefing of the game. We all chipped in preparing lunch, and ate it together on the patio.

“Hey, I know,” I suggested enthusiastically as we cleared the plates. “Why don’t we all play some board games this afternoon? Let’s make a day of it. Have some real quality family time.”

Liz and Natalie were all for it, with Natalie rushing off to grab the games. Julie shot me a look that could have shattered glass, but she put on a tight smile for her big sister and niece.

Julie’s sexual frustration smouldered as we played Cluedo. I loved watching her fidget, and fight to control her concentration. But as the game progressed, Miss Scarlett regained her composure and got stuck in with Mrs White, Mrs Peacock and Colonel Mustard, eventually winning the game. It was me, in the library with the revolver.

But when we moved onto Monopoly, the morning’s mischief was little more than a memory. And in the innocent fun of playing board games with my family, I was overcome with the guilt of what I had done. I felt like I had betrayed Liz by taking a sexual interest in another woman. And the fact that it was her little sister, made it all the worse. To say nothing of the liberties I had taken with Julie, or at least her panties.

The board games rolled into dinner, before the four of us ended up in the media room for a Legally Blonde double bill. Liz snuggled up against me on the sofa, with Julie on her other side and Natalie on some cushions on the floor. We ploughed through the first one in relatively short order, and as we moved into the second, the regret of my earlier perversions waned. Julie and I were having a great time, quoting nearly every cheesy line together.

“How many times have you two watched this?” Liz huffed at us.

Julie and I exchanged a knowing look, then shrugged in unison with a smile. We shared a giggle, before quoting the next line together.

Liz woke up a snoring Natalie as the end credits of the sequel rolled, ushering her up to bed and asking if I was going to come up. Julie jumped in, announcing that she wanted to pull an all-nighter with a Paranormal Activity marathon, begging me to stay up with her.

“Don’t think you’re coming in to bed with us if you get scared, young lady,” Liz frowned in mock admonishment.

"Hey!" Julie protested. "It was always you who was afraid of horror movies when we were kids."

“What about me?” I asked, feigning fear. “Can I come to bed with you if I get scared?”

“We’ll see,” Liz giggled as she kissed us goodnight, and closed us in the media room so as to not be disturbed by the sound of scary movies.

The thumping footsteps and old plumbing upstairs faded away as the movie got going and Julie sidled up beside me on the couch. I became very conscious of Julie’s body pressed up against mine, and the soft, vanilla scent of her hair. She held my left hand between hers on my lap, and my other arm was around her shoulders, gently stroking her upper arm.

As the creepy scenes of the movie played, I felt Julie snuggle in tighter. I squeezed her reassuringly and kissed the top of her head, which was now resting on my chest. It wasn’t the adrenalin thrill of horror movies that she loved, I knew. It was the comfort of feeling safe and protected against them.

Her soft breast squashed against my side, and her firm thigh rubbed against mine. I lost track of the movie, instead basking in every tactile sensation. Julie crossed her legs towards me, rubbing my shin slowly with her instep. And the hand sandwich on my lap crept almost imperceptibly closer to my aching hardness.

A thousand thoughts flooded my brain as I sat there with my gorgeous sister-in-law squirming against me. The suspense of the movie only added to the tension of my thundering heartbeat. I could hear Julie’s breathing against my chest, shallow and uneven. As time went on, it only got worse.

Gradually those thousand thoughts diminished to just one: fuck her!

Gritting my teeth, my own ragged breath signalled my desire. I was going to do it. I had to. I couldn’t take her rubbing herself against me anymore. She was teasing me. She had to be.

Fuck her! NOW!

I leapt off the couch and grabbed Julie by the hips. Her beautiful blue eyes were saucers as she gasped with surprise. I pulled her down onto the cushions on the floor her niece had been laying on earlier. Clawing my fingertips into the waistband of her pyjamas and panties, I pulled both down roughly over the soft flare of her curves and down her long, shapely legs.

Julie’s mouth hung open, frozen in shock. I snatched her panties out of her pyjama bottoms, and balling them in my fist, I shoved them in her mouth as a makeshift gag. Then I manhandled the hem of her Star Wars t-shirt up her body, causing her full, ripe breasts to bounce free. I gasped myself, getting a perfect view of her swollen globes in the dim light of the television. She barely resisted as I yanked her shirt up over her face, and up the length of her arms.

With her top at her wrists, now held above her head, I twisted her t-shirt around and around to bind her hands together. Then straining to lift the front corner of the couch, I forced the twisted cotton behind the stubby timber leg to hold her in place.

Stretched out on the floor underneath me, completely naked, tied up and gagged by her own panties, Julie was the sexiest thing I had ever seen.

I crawled over the top of her, making sure not to touch her. She trembled, her breasts jiggling slightly beneath the erect nipples that betrayed her excitement. I stared into her eyes, until eventually, she dipped her gaze submissively.

“You little tease,” I whispered, touching the end of her nose with my index finger. Then running it over her chin and down her throat, I continued, “I’m going to fucking use you.”

Julie shuddered, snorting heavily through her nose. I ran my finger between her breasts, then slowly circled each nipple, careful not to touch either engorged nub. Making my way down her impossibly soft, yet flat belly, I looped her navel, then continued south. The coarse thatch of pubic hair, delicately manicured into a thin landing strip across her mound, nearly made me come as I ran my finger back and forth.

“Open them, Julie,” I very slowly breathed.

Her whole body squirmed as she released the tension that was holding her thighs tightly together. My body flushed with warmth as her legs carefully parted. Julie’s familiar scent filled my nostrils, and the glow from the television illuminated the slick sheen of moisture which had spread halfway down her inner thighs.

“You little slut.” I spiralled my finger across her soft, slippery flesh, inching closer and closer to her sex.

I ripped into my jeans like a kid tearing open a present on Christmas morning. My cock sprang free as I shuffled between Julie’s legs. Guiding the mushroom head of my cock to her opening, I drove myself deep inside her, in one, forceful thrust.

Sheathed in her sopping wet heat, the moan caught in the back of my throat. I began to fuck her with long, slow, deliberate strokes, digging my cock into her as deeply as I could. I kissed and licked the side of her face, sucking on her ear and whispering obscenities. As I ground myself into her, I grabbed a handful of her long blonde hair, pulling her head back and exposing her neck. I licked and sucked at Julie’s incredibly taut skin, almost devouring her.

I pounded Julie’s pussy for all I was worth, pumping into her with lusty abandon. The noise of her snatch slurping with every thrust rose above the deafening sound of slapping flesh and heavy breathing.

My climax built, warming my entire body with a growing tingle. I knew I was close, and held on as long as I could, wanting to savour every last moment. But no longer able to control myself, I buried my cock to the hilt in her sopping cunt and came inside her, flooding her womb with my seed.

I lay spent on top of her, inside her, paralysed by the sensitivity of my orgasm. Julie’s chest heaved beneath me as she too fought to regain her breath. After a few minutes, I sat back onto my heels, allowing my softening cock to slip from her wrecked pussy. My cum was already starting to ooze out, trickling down the crack of her ass.

Her face was turned to the side, resting on her arm. I leaned over her, turning her chin to face me. Julie kept her eyes cast down. She still had her panties stuffed in her mouth. I tugged on the delicate lace, but she bit down, not letting me remove the gag.

“Mm,” I grinned. “You still want more?”

Her blue eyes met mine by way of reply, blazing with intensity. I flushed again, not able to believe my luck.

“Do you want to come?” I taunted.

Keeping our eyes locked, Julie nodded. I wound her hair into another ponytail and wrenched her head back, sucking and biting at her neck.

“You filthy little slut,” I growled as I nuzzled my way between her collar bones. “You’ll come when I say you can come. Do you understand?”

I felt Julie’s head nod obediently against the side of my face as I kissed my way down between her breasts, following the same path my finger had taken earlier. But this time, my mission was different.

I sucked her erect nipple into my mouth, biting down and flicking the sensitive nub over and over with the tip of my tongue as I kneaded the soft flesh of her breast with my hand. Julie twitched beneath me, fighting to hold back the groans and whimpers that escaped through her panties. I pinched her other nipple and rolled it firmly between my thumb and forefinger, twisting it hard every now and then to elicit another muffled yelp.

Sucking and nipping my way across the smooth skin of her stomach, I splayed her thighs wide apart and dived head first into her used cunt. The pungent earthiness of my own cum mixed with Julie’s arousal was intoxicating. I plunged my tongue deep inside her dripping folds and lapped up everything she had to give.

Julie bucked her hips up to meet my mouth, grinding as best she could into my face. But I held her down fast. Once I had eaten her clean, I sucked her labia, nibbling on the swollen petals until I was circling her clit with my tongue. Her twitching and moaning intensified, and I redoubled my efforts.

“Remember, you don’t come until I tell you.” My tone was low and menacing.

Julie whimpered despairingly, almost sobbing. I eased two fingers into her pussy as I took her clit back into my mouth. I stirred her gooey depths before finding that subtle change in texture on the front wall of her vagina and rubbed furiously.

The sloshing of my fingers struggled to be heard above Julie’s restrained grunts. She bucked and twitched spasmodically, bristling my nose with her dark blonde pubic hair. But somehow, she found her balance under my ministrations, if only just.

But this test, she was meant to fail.

Sucking her clit and flicking it roughly with my tongue, as I had done with her nipples, I slipped my fingers from her gaping cunny. Slick with her juice, I shoved my middle finger straight up her ass.

The shock threw her off balance, and she screamed into her panties with her release. Julie was racked with wave after wave of pleasure, spasming uncontrollably beneath me in violent convulsions.

I sat back, grinning like the Cheshire Cat, enjoying the incredible view of my defeated prize, spread out before me. Julie was squeezing her eyes shut, blushing. She tried to close her legs, but I pulled them back apart, keeping her on display.

“You disobeyed me,” I observed in a low whisper.

Julie’s breath shook. I was surprised by how much I was getting off on this. Letting the anticipation build silently, I regarded the beauty bound and gagged before me.

“You’re going to have to be punished.”

Julie whimpered, which only aroused me more. Closing her left leg over to her right, I picked her up by the hips and shuffled her forward until she was on all fours. Then snatching her hair up into a messy ponytail, I wrenched her up as far as the leg of the couch would allow.

I groped her perfect, heart-shaped ass, slipping my fingers into her. Then I raised my hand and smacked her right cheek with a loud crack, leaving an angry, red handprint. Julie yelped through her panty gag, snorting heavily through her nose. I spanked her again and again, alternating from one cheek to the other until both were bright red in the flickering glow of the television behind us.

My hand stung from the spanking, and my cock was rock hard from the control I was exerting over her. I slid my full length into Julie’s sodden snatch once more, thrusting in and out a few times to coat my shaft with her wetness. Then I pulled out, positioned my head at her puckered asshole, and forced my way inside.

Her tight, muscular ring fought my entrance, but was soon sliding tightly up and down the full length of my cock as I fucked her ass like an animal. I held her hips, digging my fingers into her soft flesh. Julie’s panty-muffled grunts were deafening. Combined with the sound of my hips slapping into her ass, I was sure we would wake up the whole house.

But I didn’t care. I wanted them to wake up. I wanted Liz to come downstairs and watch me fuck her sister in the ass. I wanted the whole world to know what we were doing.

I felt my orgasm build. I pulled Julie up by the hair again, and bending over her, I bit down on her shoulder as I came in her asshole, filling her bowels with my semen. We both collapsed to the floor in a sweaty, panting mess.

Once composed, I pulled out and wiped my cock on the back of her thigh. It was the final, degrading act. I don’t know why it thrilled me, it just did. I savoured the feeling as I tucked myself back into my jeans.

But when Julie rolled over onto her back, it was most definitely over. I gently took the panties from her mouth and slipped them back up her long legs. I lifted up the corner of the couch to release her hands, and tenderly helped her pull her t-shirt back down over her body. We didn’t exchange eye contact at all. I just couldn’t. And as soon as she was reasonably covered up, I left her there on the floor and retreated to my room.

Despite having so magnificently found my sexual release with my sister-in-law, an absolute torrent of guilt and shame washed over me as I climbed the stairs on the way back to my wife. Stepping inside our bedroom, Liz was dead to the world, snoring like a lawnmower. I looked out the open window at the fluorescent Sydney skyline in the distance, thankful that she was still asleep. At least I had gotten away with it as far as she was concerned.

How things would now be with Julie would be the real test.

At breakfast the next morning, Natalie was excited about spending the day with Liz and I at Taronga Zoo. Julie was still upstairs, getting ready to go out with her friends. And I was dreading her coming down before we left. But she did, dressed in a black long-sleeved turtle neck and a red tartan mini skirt. Julie kissed her sister and niece good morning on her way past into the kitchen, however, she didn’t look at me.

My heart thundered. The fear that I had gone way too far the previous night consumed me. Well, the realisation that I definitely had. The dreadful consequences were what I really feared.

Liz and Natalie bustled off upstairs to brush their teeth and finish getting ready for the day, leaving me alone with Julie in our kitchen diner. The air was thick with tension. She stood there with her back to me. Her tight, straight blonde ponytail looked almost white against the black of her skivvy. And the only sound was the coffee machine, and the bloody plumbing from upstairs.

I couldn’t take it anymore. I skulked into the kitchen, moving up behind her. She sensed my presence and turned around, but without looking at me. I reached up and peeled down the top of her turtle neck. Julie’s throat was covered in dark, angry love bites. I gasped, my blood running cold.

Then taking her hands in mine, holding them delicately between us, I rolled back her sleeves. Julie’s slender pale wrists were heavily bruised from the twisted t-shirt I had used to restrain her.

“I’m so sorry,” I whispered, racked with guilt.

“It’s okay,” she whispered back. Then looking up to meet my gaze, her eyes twinkling and the corners of her mouth curling upwards. “I told you last time, I like it rough.”
