Chapter 1 -Sibling Rivalry

She should be asleep by now, lost in some dream world with some bare-chested hunk from one of her romance novels. She should be, but she wasn't, not with her sister in the next room. Aimee Harper lay in her bed, again regretting sharing an apartment with her twin sister, a regret she had almost every weekend. It was three in the morning and instead of the deep silence of night lulling her to sleep, she was being kept wide awake by her sister's cries of pleasure. Living with Karla really wasn't the problem; at least, not usually. When Karla first asked to share Aimee's condo, Aimee thought it a great idea. She could save money for one, which would assist her in her quest to actually do something with her photography hobby, and also have someone to split the household chores. When she didn't have to remind Karla to do her portion, that is. And, for the most part, they got along as well as most siblings. They bickered here and there, squabbled over who drank the last Diet Coke, and whose turn it was to clean their only bathroom, but they made it work. No, it wasn't the fault of Karla and her wild nights. The blame lay with their apartment's thin walls, compounded by the fact that their beds rested along the same wall. That was a fact she needed to remedy first thing in the morning and while she was kept awake by her sister's one night stand, Aimee mentally rearranged her room three times. That wasn't enough to distract her from the fact that she was privy to Karla's moans as well as the bumps of the bed against the wall. She didn't need to experience someone else's sexual exploit this Saturday night. She needed an exploit of her own.

With her eyes closed, Aimee took a deep breath, trying to calm the emotions gurgling up inside of her. She should have known how the night would end when Karla brought home… Aimee opened her eyes and stared up at the ceiling. What was his name? After a minute or two of trying to conjure up the name of Karla's new toy, she surrendered. It simply escaped her, like so many of the other names of the men her sister brought home. She never kept them for very long, so Aimee saw no need investing in the normal civilities. Besides, knowing her sister, Karla had probably never even introduced him as she scurried the man through their apartment and straight to her bedroom for the predictable conclusion to her night's activities. As Aimee recalled, Karla had barely even waved on her way through the condo and the man was too intent on Karla's heart-shaped ass to even notice Aimee was sitting on the couch in her flannel pajamas, eating popcorn, sorting through her sunrise prints, and watching an old Bob Hope movie. Aimee sighed into her pillow at the image of her Saturday night. Boy, do I live a pathetic life. She really needed to get her car fixed.

The action on the other side of the wall began a steady rhythm that sent tremors through Aimee's bed, her head bouncing slightly on her pillow. Her sister always brought home men. It was one of the main reasons she wanted out of her mom's house. She used to sneak boys into her room when they were in high school, which wasn't all that long ago, though it seemed like forever. Of course, when you're in your twenties, a year feels like a decade. That's why we think we have plenty of time to accomplish our dreams. We're young. There's always a tomorrow. Still, Aimee preferred Karla's conquests being sneaked in as opposed to having them pranced in front of her like a prize Karla won at the state fair. Sometimes, it came across like "look what I have that you don't." Aimee knew what she didn't have. She didn't need reminding.

There were times, like tonight, that Aimee wished her sister still lived with their mother and was not invading her private domicile. Aimee moved to Gainesville to gain some independence as well as some separation. When she returned to help with their sick father, she quickly found her own place to keep that independence. Well, that, plus she was tired of seeing her sister manipulate their mother. How Karla even managed to convince Aimee to allow her to move in was beyond her. Yet, that was Karla, always getting whatever she wanted.

Aimee heard something fall off Karla's night stand on the other side of the wall as her sexual cry penetrated the night. As much as she fought it, the sounds were making Aimee's own juices begin to soak into her panties, as she recognized the scene in the other room moving from foreplay to the main show. She finally succumbed to the growing excitement within her and slid her fingers under the waistband of her pajama pants down to the growing heat between her legs. Karla's whimpers seeped through the wall, as Aimee rubbed her swollen clit in cadence with the thumps of headboard on drywall. She knew she shouldn't be doing it, using her sister's sexual activity to get herself off. It felt wrong—dirty, even—but it was all she had. It had been way too long since her last date and even longer since she had sex. Besides, it wouldn't be the first time one of the twins used the other's exploits to get themselves off.

She closed her eyes and pictured her own body sprawled on the bed, her legs spread as she envisioned Clint Asher from three doors down plunging his cock deep inside of her pussy, opening her up with his massive organ. She had been using him in her fantasies for a while and his powerful face popped easily into her frenzied mind. It was her cries now echoing against the walls, as her hips thrust upward to meet his in a sweaty pounding of heated flesh. Her swollen nipples were pinched and flicked, sending orgasmic shocks throughout her body. Clint's body grazed against her clit, not her fingers drawing wet circles around the hood of her swollen pearl.

A scream split the night, shouting out her orgasm, as her body twitched underneath her fingers. Her heart pounded, as her eyes flew open at the realization that it was her scream, not her sister's, that ripped the silence. She covered her mouth with the hand that was pinching her nipple just a second ago, as her chest heaved with the lust that coursed through her. She squeezed her eyes shut, praying no one heard her, but knowing there was no way they missed it. Even with her sister's own cries of sexual pleasure, Aimee's pierced the apartment. Oh, great. Please don't let that man spend the night.
