Mary woke up feeling disoriented and confused. The bed she'd slept in wasn't her own, and what's more, she was completely naked. It wasn't until she felt the mattress shift as her brother snuggled up next to her that her memories from the previous night came flooding back.
In the harsh light of day, it seemed hard to believe that she'd actually had sex with Ray and his wife, Diane. For a brief moment, her all too familiar feelings of regret and shame threatened to overtake her, but she quickly banished them from her mind. She'd given herself over completely to her forbidden desires, and it had been one of the most magical nights of her life. She knew most people wouldn't be able to comprehend what she'd done, but she didn't care. The experience had left her feeling happier and more sexually fulfilled than she'd been in years.
She wasn't even particularly bothered by the fact that her husband, Tim would be coming home from his business trip later that afternoon. It would probably be an awkward conversation, but she planned on telling him everything as soon as he arrived. There was no way to predict how he would react. All she could do was hope that once she explained herself, he would understand.
He'd have to. She certainly wasn't going to stop fucking Ray or Diane anytime soon. Come what may, there was no way she'd go back to the way things were before.
Making Danny accept what she'd done might not be so simple, though. Despite his recent sexual awakening, she knew her son would have a hard time reconciling his image of her as a devoted wife and mother with the reality of what she'd allowed herself to become. She just hoped he wouldn't be too upset when he finally learned the truth.
Thinking about her son brought back memories of the night before. Her pussy throbbed as she remembered the taste of his cum as it dripped from Diane's well-fucked hole. Mary wished she could have been there to see the moment when Danny emptied his balls into his aunt's cunt and wondered whether she would have been able to stop herself from joining in had she been there.
The tingling between her legs intensified as she allowed her impure thoughts to take hold. She drew a picture of Danny in her mind, trying to envision every detail of his slender, boyish physique, which was just starting to show the telltale signs of oncoming manhood. She fantasized about how exciting it would feel to be pinned down by that youthful body, moaning and writhing while he had his way with her.
It wasn't just the thought of having sex with a younger man that excited her. Somehow, the fact that the man in question was her own son made her fantasies even more thrilling. She wanted to know what Danny's cock tasted like and how it would feel when he used it to probe the same hole he'd emerged from 18 years prior. Her pussy melted as she imagined the excited smile he'd have on his face as he prepared to enter her for the first time. Thinking about being her son's personal slut made her dizzy with excitement. It was filthy and wrong, but it made her pussy and breasts ache for attention.
Her lewd fantasies were interrupted by the feeling of Ray's arm draping itself over her body. He didn't say anything, so she couldn't tell whether he was asleep or awake. Either way, his touch made her feel all warm and fuzzy, and she couldn't help but lean back into his embrace.
She let out a contented sigh as his palm moved higher and came to rest on one of her breasts. Her nipples reacted instantly, hardening against his soft touch. Without a word, he pulled her closer until his erection pressed firmly against her ass.
She was trying to decide what to do about the situation when she felt Ray's free hand reach between them and guide his erection into the valley between her ample butt cheeks. She let out a muffled groan at the sensation of his warm cock rubbing against her sensitive rear entrance.
"Morning, Sis. Sleep well?" he whispered as he gave her breast a gentle squeeze.
Mary replied with a quiet, "Mmhm," as she involuntarily clenched her cheeks around his shaft.
Nothing more was said, and she quickly lost herself in the pleasure of Ray shaft thrusting between the mounds of her ass and his hands as they gently massaged her heaving bosom. She pushed back against him, making soft mewling noises as her whole body tingled with delight. Ray's movements were slow and languid. The intense urgency they'd felt the night before was gone, replaced with a feeling of warm intimacy.
Eventually, Ray's hands started moving lower. Mary trembled as he ran his fingertips over her gentle curves, eventually moving over her round tummy and down to the furry patch between her thighs.
"Can I...?" he asked, his voice husky and low.
"What about Diane?"
Mary's pussy was on fire, and she was desperate to feel her brother's fingers work their way into the moist folds of her pussy, but she couldn't ignore the fact that Ray's wife was slumbering right next to them. Somehow it seemed rude to wake her, and Mary wasn't quite sure how Diane would react to the two of them messing around without her express permission.
Her dilemma resolved itself when she heard Diane's voice say, "Don't hold back on my account."
That was good enough for Mary. Lifting her leg slightly, she guided Ray's hand down to her slit. A guttural moan escaped her lips as he started rubbing slow circles around her opening, gathering her moisture on his fingertips and dragging it up to her sensitive clit. She did her best not to squeal when he finally pushed a finger deep into her soaked canal and started working it in and out. He made sure to brush her clit with with his palm on each inward thrust. The combination of Ray's hard cock thrusting between her ass cheeks, his finger in her cunt, and his warm breath cooling on her neck drove her wild with lust.
Deciding to take some initiative of her own, she reached behind her back, grasped her brother's cock, and gave it a few strokes before guiding it toward her cunt. Ray withdrew his finger, giving her free reign to aim his bulbous, purple head at her entrance. When the angle was just right, she let go, allowing him to slide deep into her quivering hole.
Mary panted and moaned as Ray took her from behind. From that angle, his cock repeatedly rubbed over her g-spot. He kept one hand pressed firmly on her abdomen, extending her intense pleasure even further.
Soon, the room was filled with the sound of squeaking bedsprings and the wet slapping of flesh. It was too much for Mary to take. Her eyes rolled back in her head and her whole body went stiff before she broke out into a wave of orgasmic convulsions that shook her right down to her core.
Her internal muscles clamped down hard on Ray's cock, but he didn't slow the pace of his fucking. He kept driving into her, harder and faster, pushing her to ever increasing heights of ecstatic bliss.
Mary let out a surprised squeak when Ray hugged her tight and rolled their intertwined bodies until she was laying on top of him, taking his cock from below.
"I love you, Mary," Ray groaned before planting a series of wet kisses on the exposed skin of her neck.
"I... love... Ungh!... you... too," Mary replied between each powerful thrust of her brother's cock.
