Bethany lay in her bed, the covers thrown off and her window open, allowing the warm night air to dance over her exposed flesh. She wore only a tight t-shirt, pulled up over her pert breasts, her nipples erect, tingling in the slight wind. A pair of sweat shorts were dangling from one petite foot over the side of the bed. Her short, skinny legs were spread apart, allowing her left hand unobstructed access to her small, hairless pussy. Bethany had just shaved it this evening and loved the feel of the smooth, tender skin. She ran a finger in between her labia and spread the wetness she found there all around the puffy lips. Her right hand was tugging and squeezing her left nipple, sending little electric-like shocks all the way down to her toes.
Her pale skin shone in the dim light that reached through the window. Bethany's thick, curly, raven hair framed a heart-shaped face with large, dark eyes, small, almost pug nose and tiny but full crimson lips. Her lips parted as a sigh of pleasure escaped from between them as she lazily teased her hardening clitoris. Only moments ago she'd been sleeping soundly until a rhythmic thumping had woken her. It took her only a few groggy moments to realize her parents were fucking again. Since they'd reunited after a lengthy separation it seemed that was all they did. And Bethany's bedroom was next to theirs so she usually knew when they were doing it.
Not only could she hear the bed thumping against the wall and the springs creaking but also moans and muffled words. At this very moment Bethany could hear her mother groaning ever few seconds. She imagined her father was forcefully thrusting inside her in short intervals. Her father, who she hadn't seen in years, was almost a stranger. When Bethany first saw him enter the apartment behind her mom she didn't even recognize him. With a trace of shame she remembered wondering who this cute guy was her mom was bringing home with her. He was taller than she remembered, broad-shouldered with an athletic build. His short, brown hair had streaks of grey and his eyes were bright and blue. She recalled him glancing over her body in much the way she had looked at him. When her mom told her who the man was, it was a very awkward moment for her.
That first night Bethany had heard them fucking. She couldn't believe it. Her mother was an attractive woman, but she'd never thought of her as being sexual. The things Bethany had heard her say through the wall made her blush. She could barely make eye contact with either of them the next day. What was worse was that Bethany kept stealing glances at her father. During the night, she'd heard her mother cry out that she'd "missed his big cock". Ever since then she'd found herself wondering just how big his cock really was. It didn't help matters that every now and then she'd catch her dad also looking at her strangely, especially whenever she walked around wearing her short robe or something a little provocative. She was sure he was checking her out.
So things had been a bit strange for the past month but Bethany had just turned eighteen, had graduated high school and would be going to college in the fall. Therefore she would put up with the awkwardness for a little while longer. This was, after all, the happiest she'd ever seen her mother so she wouldn't ruin it for her. Bethany grinned to herself. If she were getting fucked on a regular basis like her mom was she'd be in a good mood too!
As it was, she'd have to make due with her fingers at the moment. As she lay, listening to her parents screw, she began to masturbate in earnest. Bethany slipped a finger inside herself, then another. Gasping from the pleasure, she slowly began to work them back and forth, massaging her aching clit at the same time. Her pussy was now soaking wet and Bethany bit her lip, trying not to moan too loudly. Behind the wall, it sounded like her parents were climaxing. Bethany wondered if she could come at the same time they did. She began to frig herself faster, bucking her hips up and down quickly while she squeezed even harder on her left nipple. Now, as she felt her orgasm approaching, she began to cry out, unable to stop herself. She quickly slid a third, then a fourth finger into her tight hole. "Oh, god....oh...oh....oh..." she moaned as she bucked and squirmed. She came hard. Her slim body shivered in the feeble light. She gave a shuddering moan as multiple orgasms coursed through her. After several moments she laid gasping and shuddering, smiling serenely.
Then Bethany realized how quiet it had become. She wondered how long her parents had been finished and if they heard her coming. She withdrew her wet, sticky hand and reached over to find the tissues on her bedside table. That was when she noticed the vague shape standing outside her door. A wave of panic hit her. Bethany silently cursed herself for not shutting her door all the way. She'd left it open before bed for ventilation, not anticipating to masturbate tonight. Before she could pull her shirt down or cover herself, the bedroom light suddenly blazed on. She blinked, stars in her eyes for an instant. Then she stared at the form of her father standing in the doorway. She froze beneath his gaze. His eyes were fixated on her, his mouth slightly agape, a distant, dreamy expression on his face.
Bethany vaguely noticed that her father was wearing only a pair of boxer briefs. Her eyes fell without thinking toward his crotch. She saw a great lump there. She looked back up into his eyes and saw that he was staring her outstretched legs, her wet pussy fully exposed. Bethany was petrified. She couldn't even command her limbs to work and hide her nudity from her father. Everything seemed to be going in slow motion. Then her father spoke, his voice guttural and slow. "I...I heard...I thought I heard...I thought something might've been wrong." His voice was apologetic but his eyes lingered hungrily over his daughter's naked form.
Bethany, her eyes wide with apprehension and confusion found herself smiling weakly. She knew she should cover herself but somehow she enjoyed the look of utter captivation on her father's face. He was looking at her the way a man looks at something he wants to possess. Natural instinct was overriding any familial feelings he had at the moment. It made Bethany feel powerful and womanly. She liked it.
"I'm okay," Bethany said softly, "Just having a little fun." She gave her shoulders a little, innocent shrug causing her small tits to jiggle slightly.
"Uh, yeah," he stammered. "Sorry to, you know, interrupt." Still his eyes were fixed on her. "You should probably shut the door when...you know."
