An inch or so of wet snow covered the lawns and bushes on the street. The roads and sidewalks were clear and wet; black paths through the whiteness. Lois sighed and began to rummage through her messy bedroom for the third time, trying to find her new boots. She had called in sick today, depression having temporarily gotten the better of her. She had gone to bed early the night before, cuddled in heavy blankets against the cold, raw early December air that somehow found its way into her apartment despite the fact that she had turned her thermostat up over 80 degrees. She lived in the bottom unit of a three-family triple-decker. Her sister and brother-in-law owned the building and occupied the top floor with their three kids. Ted and Jenny did alright, but keeping this old house heated and properly maintained really stretched their resources. Ted worked for the city and Jenny was a mostly work-at-home mom who did bookkeeping while her kids were in school and then played housewife/mother when school let out. They were more interested in reliable tenants than they were in well-to-do, though unpredictable tenants, so they kept the rents low. Thus, the house was always a bit run-down. Lois had awoken this morning, horny and damp from a dream. Despite the cold air in her apartment, she was already sweating as she moved her fingertips under her sweatshirt and over her nipples, which immediately puckered as they hardened. Her other hand caressed her belly for a moment and then slid downward, under her thermal underwear and into her panties, through her patch of moist pubic hair and down to where she could cup her mound. Her own touch made her sigh explosively. A tingling, nearly burning sensation emanated radially from her lower stomach downward to her wet cunt when she began to rub herself with a slow, practiced, circular motion. The palm of her hand lightly grazed against her clit as it emerged from its folds while her fingers began to lightly caress her labia. She gradually increased the intensity and speed of her stroking and then abruptly backed off for a moment, feeling her hips relax before quickly speeding up again. She did this familiar dance with herself several times, the sensation ramping itself up in intensity, her horniness increasing more and more with each cycle. Finally, she began to feel her wetness begin to seep from her cunt lips. At this, she crooked her middle finger and inserted it fully into the wet opening. She felt her wetness run onto her fingers and puddle in the hollow between her knuckles. When her clit began to ache, hungry for her own touch, she brought the palm of her hand down slowly, gradually, firmly, pressing on her clit. More fingers went into her now-very juicy cunt; some going out and some going back in in a seemingly random dance as she brought more and more pressure to bear on her clit. Her middle finger stroked the ridged roof of her cunt in a beckoning motion. Her wrist, bent severely to accomodate the motion, ached slightly. Her breathing became ragged and she craned her neck back into her pillow, her mouth open and eyes closed tightly, as the first moan escaped her throat. She raised her hips and dug her heels into the mattress as she gyrated her pelvis just so. Lois gasped as the electric hum of sensation in her loins amped up to a strong flow of power, running downward. At just the right moment, when she knew her body was ready, she slid her slippery fingers from her cunt and found her clit with her index and middle finger. Grabbing an erect nipple with the fingertips of her other hand, firmly squeezed and pulled as her lower hand began to briskly frig her clit. It didn't take long at all. It never did. Her body shuddered, temporarily beyond her control, and she let go as a long, quaking orgasm overtook her. It always reminded her of body surfing at the ocean when she was a little girl. If you caught the wave just right and released your body to it, the water would grab you and propel your body forward. She had always loved that delicious feeling of abandon and reward. Minutes later, still panting but now weeping, she lifted her head from the blankets and saw the snow falling outside. It wasn't much, but it was the first snow of the season. She lay back, thinking about the orgasm she had just had. She had started out fantasizing about the guy over in the next office again, the one with the big shoulders, big hands and soulful eyes. Her fantasy began with those big, strong, beautiful hands on her and quickly segued to him fucking her on the table in the conference room. Sadly, in the end, at the crest of the orgasm, it wasn't the office guy who was fucking her at all. It was Jack. Fucking Jack. Fucking fucking Jack. Jack had dumped her two weeks before. They had been together for six months. She was far from over it. She believed that she loved him and that they were a good match. She was 35 years old and ready to settle down with a man. Finding men was no problem for Lois. She was tall and fit, with shoulder-length blond hair and a lovely body. Her problem had always been finding GOOD men. Jack was THE good man, she thought. And then, without any warning, he had simply ended the relationship, using phrases like "going nowhere" and "not what each of us needs." Fucking Jack. Lois rolled over onto her stomach and cried pitifully. She had tried to be brave - stoic - up to this point. She had made it a point to get up each day, dress attractively and get out of her apartment to go to work. It was getting more and more difficult as the weeks passed. When she finally got out of bed to go pee, she stopped and looked at the snow. The thought of wet, slippery roads and her snow-covered car quickly dispelled any thought of going to work today. She just wasn't up to it. Instead, she had left a voice mail message for her boss saying that her car wouldn't start and she couldn't make it in. After, she listened to her niece and nephews running around upstairs getting ready for school. She heard them arguing amongst themselves on the stair landing outside her door as they came down to head for the bus stop, Jenny yelling after them from upstairs. She went to the window and watched them head off down the sidewalk together in the gentle snow. Then she had gone back to bed with a box of tissues to cry and finally rock herself back to sleep. She awoke again around 11:30 and got up and ate some breakfast, watching the snow fall outside. She noted that the snow was changing, the flakes getting bigger and heavier. Soon it would change over to rain, perhaps melting the inch or so of snow that had accumulated. The thought made her sad. She decided to go out and walk a bit to mark the season's first snow and because it seemed a fitting thing for her to do given her state of mind. She pulled on a sweater and jeans, warm woolen socks and found a hat and gloves. However, she was unable to find her boots. She sat down on the couch, annoyed. She tried to remember where the boots might be. She went onto the landing to look, knowing full well that they wouldn't be there. There had been no snow before today so she had not had occasion to wear them. As she stood on the landing, she remembered her young niece yelling at her brothers as they banged down the stairs. Then she remembered: her niece had taken them to play dress-up just the week before. They were probably still upstairs in her room. She went up the stairs and paused outside the door. It was silent inside. Normally, if Jenny was working from home, the radio would be on. "Great," she thought, "there's no one home. I guess I'll just have to wear sneakers out in this slop." Then she remembered that Ted and Jenny sometimes left a spare key under the mat. She turned and lifted the mat and there, amidst a swirl of dirt and brown pine needles, lay the spare key. As she bent to pick it up, she thought she heard a man's voice from inside the apartment. She stopped to listen. Hearing nothing, she thought she should knock before going in - just in case. Lois knew she was always welcome in her sister's place, but she knew Jenny might be annoyed if she simply burst in. Lois knocked once, lightly and hesitantly, and then shook her head and unlocked the door. "There's no one here," she thought. The voice she heard could just as easily have come from the street. If Jenny were home, the lights would be on and the radio blaring. "How can she work with all that noise?" Lois often wondered. Lois unlocked the door and opened it a bit. Standing still, she listened for a moment. There was no sound and all the lights were out. She was relieved that Jenny was out as she didn't feel like talking about WHY she had stayed home today. It felt strange to be in Jenny's apartment when it was quiet and still like this. She was so used to seeing it busy with her young niece and nephews, loud with their laughter and screaming and music from the radio. She padded through the silent apartment in her stocking feet. The falling snow seemed to absorb all sound. There was such a feeling of silence and awe considering the chaos that was the norm for this household. She headed down the hallway to her niece's bedroom to find the boots. The bedroom was actually a dining room, with a built-in hutch and elaborate ceiling light fixture. Jenny and Ted had decided to use it as the girl's bedroom and had moved their small dining room table to the kitchen. It was cramped in the kitchen, but at least their daughter had her own room now. Lois was sure she'd find her boots in the room. Her niece often borrowed Lois' clothing and accessories and tried them on in the solitude of her room. This wouldn't be the first time Lois had gone into her room to retrieve her possessions. In her niece's room, she began to rummage around. There was a small pile of clothing that her niece has "borrowed" from Lois earlier next to the pocket doors that were always closed, serving as a wall between her niece's bedroom and the living room. She bent down and, reaching into a pile of clothing, felt the boots. She chuckled and had just grabbed for them when she heard a sound. She froze, listening intently; apparently she WASN'T alone in the apartment. She heard murmuring from the rear of the apartment, near the door she had just come in through. She thought it strange that Jenny would lock the door if she were home. There were footsteps coming down the hallway. The door to her niece's bedroom was open to the hallway and she heard her sister Jenny's voice say ".....here." Lois stood up and faced the door, the boots held in her left hand. She expected that Jenny would notice her and then she could explain how she had let herself in. Instead, Jenny walked right on past the bedroom door, not even noticing Lois. She was followed closely by someone else. Lois was unable to see who it was in the dark hallway. The two of them stopped in the hallway just outside of the living room next door. There was the sound of a kiss and the rustling of fabric. Then, Lois heard a man's voice clearly say "I want you NOW." She heard the unmistakable sound of wet lips smacking. Jenny moaned and sighed. Lois heard whispered entreaties, too soft and low to make out. Lois looked up at the gap between the pocket doors. Two figures moved into the living room, stumbling, locked in embrace. Lois's jaw dropped and her eyes grew wide. It was Jenny and Lois's brother-in-law, Mark. Her mind raced. "Jenny and Mark?" Lois knew them to be good friends. Mark often came over to see Jenny and drink coffee. Mark was a nice enough guy, though his reputation among her sisters was that of a very horny and suggestive man. Still, he never did more than occasionally leer at them and he WAS good to her sister (his wife) Marie. But this was entirely different. Mark and Jenny stood in the middle of the living room, kissing, with Jenny's arms around his neck while his hands undid her jeans. After the jeans were unbottoned, Mark slid his hands around Jenny's waist and down under the seat of her jeans and over her ass. Mark, at six-feet-three inches tall, towered over the the shorter Jenny at five-foot-six. His arms were stock-straight down her back as his hands were buried wrist-deep in the her jeans. Jenny murmured and lightly moaned through the kiss as Mark's hands cupped her ass inside her loosened jeans. Jenny then stepped back, loudly breaking the kiss, reached up and began to unbutton Mark's shirt. Jenny was built very differently from Lois; in fact, they hardly resembled one another at all. Where Lois was tall and lean, Jenny was shorter and more squat. They were both athletes in their youth; Lois a basketball player and runner, Jenny played softball and ice hockey. After giving birth to three children and turning 40, Jenny had grown softer and a bit more ample through the waist and butt. Lois watched in shock as Jenny removed Mark's shirt and just as quickly, he pulled her top over her head and slowly knelt, kissing her shoulders and chest, lingering between her breasts on the way to her tummy. Jenny smiled and tossed the top and his shirt onto a chair and reached behind her back to unsnap her bra as Mark coaxed her jeans over her hips and slid them down to the floor, leaving her clad only in a pair of purple panties and white socks. Lois stood frozen there, looking through the crack between the doors. Her view was unobstructed. They stood in the room's center, perhaps ten feet away from her. Since the room she was in was darker than the living room where Mark and Jenny were, it was unlikely they'd see her. "I can't fucking BELIEVE this," thought Lois. She didn't know what to do. If she said anything NOW, they'd have to know she had seen everything so far. They were, after all, in a highly-compromised position. Still, she'd be put in an EXTREMELY awkward position herself. What should she do? Should she wait it out and pretend it never happened? Should she tell Ted or Marie? Such a revelation would likely rock both marriages, both families...and they both had kids to boot. She simply didn't know what to do. So, despite herself, she remained silent and still, watching. "Up," said Jenny in a low voice. Mark complied, running his hands once over her ass and the back of her thighs as he broke a kiss at the bottom of her rib cage. As he stood up, Jenny moved in closer, bringing her arms around his waist while he gently held her face and kissed the top of her head. Jenny then unbuttoned his pants and dropped them to the floor. "I have a little early Christmas present for you," chuckled Jenny. "Hmmmmm....why don't you stand over there." Jenny led Mark to a far corner of the room Mark turned and, smiling impishly, faced the center of the room. Then he kicked off his pants and was left in HIS socks and underwear. Lois' face turned red as she realized that she was soon going to see her brother-in-law naked. Mark was a good-looking man. He was tall and dark and reasonably fit. He had a nice chest and strong shoulders. "Turn and face the tree," giggled Jenny. "Remember....this is a Christmas present." "Okay.....Mrs. Claus," laughed Mark. "Where's the mistletoe?" Jenny walked over to Mark and dropped to her knees. "Here's your mistletoe," she said as she ran her hand over the bulge in his shorts, kissing his cock through the fabric. A bright smile appeared on Mark's face as Jenny pulled down his shorts and his cock sprung free. Lois caught the briefest of glimpses of it. It was about average size, to her experience, with a slightly-larger-than average head. Lois involuntarily looked away. "My GOD!" she thought, her sister was about to go down on her brother-in-law. What would Ted think of this? What about Marie? "These guys are crazy," Lois thought. "This is just plain wrong....and they've obviously done this before." Lois wracked her brain trying to come up with a way she could escape the apartment unnoticed. There was simply no way. She was close enough to them that they'd hear her if she moved too much. She was trapped. She stared at the threshold of the door to the room she was in, vowing not to look through the opening between the pocket doors again. "I WON'T watch this!" she reassured herself. "It's wrong and I don't condone it, but there's nothing I can do to stop it short of bursting in on them and I am NOT going to do that. I'll somehow come up with a means...a strategy...a tactful way of letting Jenny know that this is NOT wise....but I'll do it later. For now, I'll just have to hide out here until I can sneak away." Then....Jenny heard a smacking noise followed by a low, slow moan from Mark. Despite her best intentions, Lois brought her head around so that her left eye was gazing through the crack between the doors. What she saw made her gasp. Mark stood where she had last seen him, his legs slightly spread and his undershorts around his left ankle. He was nude from the ankles up. His head was rolled back and his eyes shut. Jenny knelt in front of him, her back turned to Lois, naked except for her panties. Her head with its short, brown hair moved back and forth in front of Mark's crotch. While Lois couldn't see any penetration, it was obvious that Mark's cock was in her mouth and that he was enjoying the experience immensely. Lois could hear the wet sounds of cocksucking. Jenny moved slowly and steadily on Mark's cock. Lois had always thought her sister a bit of a prude, so the sight of Jenny expertly servicing Mark was even more of a shock. She seemed to be pretty good at it. Lois considered herself pretty good at giving head; she had been instructed by her friend Mary-Margaret in high school and then by her father's best friend, Bill, while interning with his company when she was 18 (that's another story for another time). She wondered where Jenny had acquired HER expertise. Jenny fucked Mark's cock with her mouth steadily for a few minutes, then released it with a loud smacking sound. Then, although Lois couldn't exactly see everything, it was obvious that Jenny was licking his shaft and sucking on his balls. Lois looked away again and spent several long minutes hearing Mark's moans and words of encouragement ("Ohhh....that's right, Baby.....") and the smacking and popping of Jenny's mouth on his cock and balls. As Lois' eyes bored a hole in the hallway wall, Jenny continued to suck Mark's cock. And although Lois would never admit it - in fact she'd even deny it to herself - she was getting wet and excited. Finally, she was relieved to hear Mark whisper "Alright, Baby.....let me." Lois continued to look away as she heard some shuffling and moving around. "Yeah...lay...yeah...there..." said Mark. Lois heard a squeak as Jenny reclined on the couch, then she heard Mark take a deep, long breath and murmur "Oh....it's so beautiful." She bit her lip, sure that Mark and Jenny were about to fuck. She stole a glance through the door just as Jenny released a shuddering breath. Jenny was now laying on the couch opposite the door on the far side of the room, perhaps ten feet from where Lois hid. Her head was in the back corner of the couch as she lay diagonally across it. Mark knelt on the carpet in front of the couch. Jenny's right leg was over his shoulder, her left leg on the top of the back of the couch. Her purple panties were in the middle of the floor. Mark's nose was nestled in Jenny's pubic hair. Jenny stroked his head with one hand and squeezed her own tit with the other. Lois could tell from the way Mark's shoulders worked that his hand was also between Jenny's legs. Jenny panted and moaned, tilting her pelvis back and forth to get maximum effect. Lois was both repulsed and mesmerized. "Oh, dear God....this is like watching porn," she thought Lois. "All I wanted to do was get my boots so I could take a walk in the snow....." Apparently Mark was as good at this as Jenny was. Mark worked slowly, with a seeming gentleness while Jenny writhed and breathed heavily. Mark continued to eat Jenny's cunt. Both of Jenny's slightly chubby legs were now over his shoulders with her heels dug into his back. She softly and breathlessly urged him on "Oh...oh....God....eat....eat.....fuck....fuck....oh....yes....yes....I love the way you eat me....." Mark lifted Jenny's right leg off of his shoulder and held it aloft with his left hand while he rocked forward and reached for her right leg, all the while continuing to eat her out. As soon as he had both of Jenny's leg aloft and spread wide, he began to move his mouth over her cunt with long, strong, slow strokes. His tongue slowly, steadily washed up and down from her ass to her clit, back and forth, again and again. Soon, Jenny began to moan, then rock her hips up and down. Her moans became louder, then her toes curled over and her arms flailed as she came, crying out indistinctly. Mark backed off a bit and gently lowered her legs so that her feet came to rest on the couch. Lois could see his smiling face in profile as he looked up at Jenny, whose right arm was thrown across her eyes as she recovered her breath. Mark's face was smeared with Jenny's juices, shining in the cold light coming from the window. Lois stared in disbelief at what she was seeing. She could feel her face burning with a deep and embarassed blush. "Oh God, Jen, I LOVE your cunt," he exclaimed. Lois had to bite her lip to refrain from groaning in disgust. Jenny looked at Mark and the slightest smile crossed her lips. "I love what you DO to it," she breathed, shifting her weight. "I can't believe he used the C-word with my sister!" thought Lois. Lois had once left a man's bed, mid-fuck, over his use of the word. Mark stood, still in profile to Lois. His cock was hard. Lois noticed a fine filament of precum reaching for the floor as he moved toward Jenny, who, smiling expectantly, spread her legs in welcome. Mark looked down and, noticing the precum, caught almost the entire thread with his hand. He knelt between Jenny's legs and, as she positioned herself to be fucked, smeared the wetness on her shiny labia. Lois watched as her sister's cunt fell wide open under his touch. Lois had seen a cunt or two in her time, but never one of her sibling's. Jenny's lips were swollen and open, like a flower, and glistening. Her thatch of pubic hair was longish ginger-colored, like Lois's. "Want me?" Mark asked Jenny playfully grabbing his cock and pointing it at her opening. "Now," she replied, her eyes locked on his cock. Mark smiled and rolled his cock around a bit, rubbing the head on Jenny's cunt. It drew up the wetness like a wick. "Oh, Baby..." sighed Mark as Jenny exhaled slowly and long. After another minute or so of rubbing and stroking, Mark put the head between Jenny's lips, where it disappeared slowly. He pushed into her about halfway, then withdrew a quarter of the way. The portion of his cock removed from her was wet and shiny, even in the early afternoon's subdued light. He slowly slid his hips forward again and seemed to bottom out. Lois's hand went involuntarily to her crotch. She worked hard to control her breathing. It was difficult. She looked to her right. Both Mark and Jenny moaned, bringing Lois's eyes back to the couch. He was on her now, fucking her with long, slow, steady strokes. He alternately rotated his hips and thrust, stirring the pot. Jenny's legs were wrapped around his waist, pulling him into her and grudgingly allowing him to pull back before stroking into her again. Jenny's right hand was on Mark's left arm, her left arm around his neck. They kissed deeply, moaning into one another's mouth, the sound muffled by their active tongues. For the next fifteen minutes, Lois watched Mark and Jenny fuck. They changed position every few minutes. Mark atop her, Mark behind her, Jenny atop Mark, Jenny on her side while Mark fucked her hard, his balls slapping against her wet and shiny ass. At one point, with Jenny on her knees on the carpet with her upper body laying across the couch, Mark seemed to climax, his back arched as he shuddered. When he finally stopped and exhaled, after perhaps fifteen seconds, Mark chuckled and murmured something about a "close call" before rolling Jenny onto her back again and entering her again. Mark slid his hands under Jenny's back and grasped her shoulders, pulling close to her. Her knees were bent so that her heels dug into the top of Mark's thighs, just below his ass, which flexed and moved as he fucked her hard and fast. They grew louder as their movements became more frenzied. Jenny began to moan in time to Mark's thrusts; "Oh....fuck me......fuck me....fuck me......" Mark grunted each time he bottomed out, his exhalations punctuated by the slapping together of their wet flesh. The stroking became more frenetic, the sound of slapping skin louder. Lois, suddenly coming to her senses and seeing an opportunity, finally managed to extract her finger from her wet cunt to take advantage of the noise the two were making and sneak out of her niece's room. She retreated quickly and quietly down the hall as Jenny pleaded "harder....harder!" She opened the door as Jenny cried "Here! My nipple!" This final entreaty hung in the air as Lois quietly closed the door behind her. She padded softly down the stairs, her cheeks flushed and hot. With the door closed it was much quieter, though she was certain she heard Mark cry out as he came. Lois softly padded down the stairs. Looking out the window leading to the second floor's back porch, she saw that the snow was changing over to rain. She quickly opened the unlocked to her own apartment and slipped inside. Her head and body buzzed. In spite of her shock, she ran for her bedroom and, pulling down her pants and panties, knelt on her bed and buried her face in her pillow. Her hand found her clitoris again and she masturbated furiously. This time, Jack did not appear in her fantasy. Instead, she was in Jenny's living room with Mark's cock buried deep inside her. She came and came before finally collapsing on her unmade bed. She could hear rain and sleet pelting her window. Soon, Jenny's kids would arrive home.
