Sunday, June 9.

Creak creak creak creak…     

A now-familiar noise filtered through the ceiling sometime in the wee hours. Linda and Sarah were still dead to the world, entwined in each other’s arms but, in time, Linda started her ascent to the surface.

Creak creak creak creak…

Although she fought against it, the persistent noise pulled her toward consciousness. The next moment, Linda opened her eyes.

Creak creak creak creak…

Her brow furrowed.

What the fuck? Oh.

She realized what was happening.

Ah, my sixteen-year-old son. At it again.

She looked over to the yellow glow of the electric Westclox. One twenty-three. Linda felt her sister moving, her breathing disturbed. The next moment, Sarah looked into her sister’s eyes in the virtually non-existent light.

"Here we go again," Sarah whispered in a sleepy voice, rolling her eyes. The noise quickened, and then they heard a muffled groan. A few creaks in the floorboard above and the rhythmic creaking slowed to a halt.

“All of that wasted cum,” Sarah lamented with a gentle sigh.

“That poor guy’s just wearing his cock out.” Linda gazed at the ceiling. “So sad. I wonder if he has a girlfriend?”

“No. I can guarantee you that.” Sarah pulled away from her sister’s embrace, stretching her naked body out like a big cat and emitting a muffled groan. “Otherwise, he wouldn’t be home all the time.” She switched on the lamp atop the nightstand, creating a soft, incandescent glow around the bed. Sitting up, she turned to her disheveled, sleepworn sister. They eyed each other’s nakedness, exchanging smiles.

“He’d be out dating and getting laid, like any normal high school guy.” Sarah reached out and placed her hand flat between her sister’s breasts. Linda placed her hand over Sarah’s.

“What will we do with that guy?” She asked. Sarah arched an eyebrow and smirked, saying nothing.

“Oh, please.” Linda was fucking her sister, and loving it, but her son was something else.

“So, I’m okay, but Billy is forbidden?”

“Sarah!” Linda caught herself, covering her mouth. “That’s different.”

“Billy and I are just a year apart.” Sarah crossed her arms, again raising her brow. “Although he’s not nearly as mature as me.”

Linda snorted.

“Hey, I AM mature!” Sarah fought to whisper. “And whether it’s me or him, it’s still incest, so there.” Now she was pouting.

“Just what we need, Sarah.” Linda pulled herself up, sitting shoulder to shoulder with her sibling.  “It’s enough we’ll have to pretend nothing happened once we get home. I know you can control yourself, but god help me if I get Billy going.”

“His cock must be raw as hell.” Sarah rested her head on Linda’s shoulder. “A nice, wet pussy is what he needs. At least someone needs to teach him about lubricants.”

Linda nuzzled her sister’s hair, still processing what had happened since the previous night. She was also, much to her surprise, seriously pondering what sex would be like with her son, and whether she might as well pull him into her and Sarah’s world of taboo.

“How long have you been taking the pill?”

"Oh, not long," Sarah replied.

“Do you have any on you?”

Sarah gave her sister an incredulous look. “Really?”

Linda felt like a naughty teenager. She nodded. “Well, you’re the one talking about sex with Billy. Or was that just bullshit?”

“Fuuuck!” The young woman hopped to her feet, heading for the door.

“Cover yourself, just in case.”

Sarah slipped on her bathrobe, disappeared for a moment, then returned. She handed the bubble-pack of small pills to her sister.

Linda said nothing, but took a pill from the pack, popping it in her mouth. 

“Hand me the water.”

Sarah obeyed, watching her sister take a few sips, swallowing.

“You know it doesn’t take effect immediately.”

“I know, I know…” Linda handed the glass of water back to her sister. “I’ve taken them before, but it can’t hurt.”

“What are you thinking?” Sarah, aroused at the prospect of what Linda was considering, traced the tip of her forefinger around her sister’s areola, making it pucker.

“Here.” Linda held her breast up and, without hesitation, Sarah took it in her mouth. 

“Ahhh…” Linda exhaled. Sarah reached up to tug on her other nipple. “I never get tired of this, honey. Suck my tits anytime.”

Sarah moaned, her mouth full of sweet flesh. Linda continued.

“I can’t believe I’m considering my son as a lover.”

“Mmmmhmmm,” Sarah agreed, never letting go of her object of affection.

“Ohhh, god, you’re making me wet again.” Linda started rubbing Sarah’s bare chest, igniting her nipples as well. 

Sarah released her sister’s breast. “Fuck, yeah, play with my tits.” By now, Linda was gently tugging at her sister’s nipples, rolling them between her fingers.

“Such lovely tits.” Linda leaned over to take one in her mouth. Sarah whimpered, pressing her breast against her sister’s full, red lips.

“Ohhh, my god,” she whispered as big sister slipped a pair of fingers into her sopping wet pussy.  “God, yes…ungh…” Sarah writhed and bucked against her sister’s hand. “God, yes, touch my spot. Rub it!”

Linda cradled the young woman, sucking her nipple as she massaged the spongy area directly behind Sarah's clit. Her body was so different than Dolores's but responded just the same.  Linda relished the taste of Sarah's skin, inhaling the gentle scent of Lifeguard soap, her fingers maintaining a steady, curling rhythm.

Sarah nuzzled her sister’s hair, trying not to moan, resting a hand on the back of Linda’s head as she suckled.

“Oh, fuck..yesss…” Sarah couldn’t keep still, feeling the approaching climax. “Please don’t stop…yes! Coming!”

Linda moaned against Sarah’s breast.

Steady as she goes, my love. Steady…steady…

A yelp escaped Sarah’s mouth as her body spasmed, the climax taking her. She allowed Linda to finger her just a little more before pulling her hand away. Linda gently kissed Sarah’s wet nipple, watching as her sister crested the orgasm, her body vibrating, eyes wide and mouth agape, unable to take a breath.

“Yes, my love,” Linda cooed as their eyes met. “Yes.” She licked and sucked her sister’s wetness from her fingers while Sarah watched.

Goddamn, this is so kinky and perverted, but so fucking sexy!

Just as Sarah was catching her breath, another sound returned.

Creak creak creak creak...

Still recovering from the climax, Sarah again looked into her sister’s eyes and laughed. Linda glanced up at the ceiling.

"Well, what do you think?" She asked, leaning over to give Sarah a peck on the mouth.

“Throw caution to the wind?” Sarah returned the kiss, although this one lingered. The young woman enjoyed the scent and taste of her own arousal.

Linda nodded, placing her feet on the floor. She couldn’t believe what they were about to do, but only twenty-four hours ago, she wouldn’t have believed she would be getting off with her sister! “Get your robe on.” Linda covered herself, cinching the garment at the front. “We don’t want to terrorize him outright.”

The sisters, concealed in bathrobes and nothing else, made their way up the stairs, their feet stepping gingerly, desperately trying to avoid making the floor creak. They lingered outside the bedroom door.  The sound had intensified.

Squeak squeak squeak squeak…

“We’re really doing this, huh?” Sarah whispered. Linda nodded. It was Sarah who knocked on Billy’s door.

“Billy?” Linda turned the doorknob, slowly pushing the door ajar. “Can we come in?”

“Mom? Sarah? What is it?” Billy’s voice asked nervously. Linda stepped into the room followed closely by her sister.

Damn the torpedoes. Full speed ahead!

“Honey?” In the dim light, Linda saw Billy had hastily pulled the blankets up to his chin. She also saw his cock straining upward from underneath, making an impressive tentpole. “Are you okay?”

“Uh…” The young man hesitated. “Yeah, Mom. Why do you ask? What’s wrong?”

Linda tried not to stare at her son’s healthy, albeit concealed, erection. Already, the wetness was returning. She fought to keep calm.

Son of a bitch if my brain isn’t spinning up. I’m so fucking horny!

 “Well, Sarah and I are hearing strange noises from up here.”

“I didn’t hear anything.” Billy kept shielding himself with the blankets. Linda remained at the foot of her son’s bed, hesitant to move closer, but Sarah circled around to the other side. The young man glanced at his aunt, then back at his mother.

“What are you doing up here?” Sarah asked, her voice almost mocking. Almost. “What’s with all the creaking?” Boldly, she grabbed the blankets and whipped them back.

“Oh, mercy!” Linda gasped as Sarah looked up, eyes like saucers.

“Fucking look at that!” The young woman marveled, unable to believe what she was seeing.

Before them, Billy lay, stark naked, his penis jutting at full mast from a patch of thick, brown pubes. His balls, also covered in hair, bulged, swollen, from underneath the base of his cock. 

It was the first time Linda had seen a male organ, especially her son’s, in eons. In addition, this one looked like it was about to blast off.

God help me, look at that magnificent thing!

 Her brain hungrily absorbed the vision, memorizing every delicious curve, indentation, and vein.  Yes, it was a cock and, yes, it was her son's, but aside from looking like any fully functional, robust set of genitalia, she couldn't help but notice something intimately familiar, something only she could recognize.

Jesus, help me.  I feel like I’ve seen this penis before, and not on Billy.

A loud, agitated voice snapped her back into the moment. 

“Mom! Sarah! What the fuck?” Billy yelled, trying to cover himself, but his aunt clung to the blankets fiercely, her eyes a mixture of lust and awe, a mischievous grin on her face.

Linda, her pussy practically dripping, would not chicken out. It was all or nothing.

God help me. Here I am traumatizing my only son and destroying our family with my carnal desires!

Linda’s senses were overwhelmed. She felt like she was outside of her body, hovering above, observing the proceedings below. She watched herself sit at the foot of the bed, her hand reaching out to rest only inches from Billy’s thigh. “Son, we can hear you masturbate downstairs.” She realized her robe had fallen open, exposing her breasts, but did nothing to close it. “My god, you’re jacking off way too much!”

“You’re going to wear that thing out!” Sarah chimed in, unable to avert her eyes from her nephew’s hardness. 

“That’s none of your business!” Billy whimpered like a cornered animal. “Why are you two doing this?”

"Billy, we'll leave you alone, if you want." Linda again used her mother voice, somehow stoking the fire even hotter. She could feel her erect clit throbbing. "We're just concerned." Her fingertips touched his warm skin. He didn't recoil but remained silent. "We're not saying masturbating is bad. Everybody does it." Her hand covered his knee. Still, he didn't withdraw, his cock remaining at full attention. "Especially healthy, young men like you."

I can’t believe he hasn’t jumped out of bed and run out of the house.

Linda looked at her sister. "Sarah, turn that on."

Sarah switched on the lamp, giving the siblings a better view of Billy’s exposed body, and his manhood.

“Oh, sweetheart.” Without thinking, Linda reached out to grasp her son’s cock, albeit gently.  Much to her surprise, he didn’t resist. She pulled the skin taut on his shaft, revealing an irritated, red pole capped by a glistening, purple helmet. For a moment, Linda felt somewhat dizzy.

He’s letting me touch it! He’s not pulling away! This is really happening!

The feel of his rod in her hand, again, awakened a vague familiarity, teasing a long-dormant part of her brain.

How do I know this? Why is this familiar? It’s more than just handling a cock.

“Mom!” Billy whined, but his voice wasn’t convincing. He squirmed under his mother’s grasp, biting his lower lip.

“Baby, look at this!” Linda loved the feel of her son’s full, luscious meat and tried not to squeeze. “Don’t you know about lubricants?”

Still, Billy didn’t respond. He just stared at his mother’s hand wrapped around his hardness.

“Sarah.” Linda motioned over her shoulder. “Go to the medicine cabinet and get me the Vaseline.”

“Aye aye!” The young woman trotted away.

Wanting to get into a more comfortable position, Linda slid all the way up on the bed, forcing her to release her grip on Billy. She leaned against the headboard, spreading her legs, fully aware she was again completely exposing herself to her son. The young man looked up from his prone position, gazing at his mother, whose robe had fallen off her shoulders. His eyes had relaxed considerably, the countenance of utter shock and agitation gone.

“Come up here, son.” She took Billy’s hand, pulling him toward her. The mere fact he was complying boggled her mind. “That’s it.” Sliding up between her thighs, he turned to rest against his mother, exhaling as he leaned back against her soft, yielding breasts.

The weight of her son’s naked body, his back pressing against her aching mounds and sensitive, erect nipples, his butt pressing against her glistening, wet pussy, his head resting back on her shoulder came perilously close to triggering an orgasm. As she rested her hands on Billy’s bare thighs, Linda clenched the walls of her pussy repeatedly, trying hard to focus on not coming. Not yet.

“That’s it, honey.” Linda tried to quell the need in her voice. She so wanted to start fucking at that very instant!

Fortunately, Sarah returned, holding a small, beige jar in her hand.  She grinned at the new position her sister and nephew had taken, both nervous and aroused at how sexy and taboo the whole thing was.

“Remove the top, please.” Linda again delicately grasped Billy’s hardness while her other hand rubbed up and down his thigh.

I’m gripping my own son’s erection and he’s not resisting. How can this be happening?

Sarah took the metal cap from the opaque glass container.

Linda motioned for her sister to hold out the jar so she could dip her fingers inside. She didn’t want to release Billy’s cock again, it felt so good and warm and alive in her hand.

“Thanks.” Linda’s eyes smiled. They belied the fact she was desperately fighting to maintain a calm, controlled demeanor.

With a big glob of Vaseline on her fingers, she proceeded to rub it, ever so gently, all over her son's shaft and balls. He sighed, pressing against his naked mother, responding to her thorough touch. It was at that moment when Linda had a revelation.

That’s where I remember this cock. Oh, my god!

Bittersweet memories flooded her brain as she fought back a sob.

I can’t fucking believe this. Keep your shit together, Linda-girl. Don’t ruin the moment. Just be grateful.

She surprised herself when her voice came out normal.

“Billy, when you masturbate, you must remember to use lubricant.” 

“Uh-huh." His voice sounded far away, blissful.

Sister watched mother and son intently, her eyes darting back and forth between their faces, then down to Linda’s slender hands expertly manipulating her son’s genitals. The next moment, Sarah let her robe slip to the floor. Linda again smiled. She knew they were both well past the point of needing to cover themselves.

“Come over here,” big sis motioned. Sarah, in her birthday suit, climbed onto the bed, sitting on her heels, knees apart, facing the two. It was obvious she wanted to be as close to them as possible and still watch. Linda nodded approvingly.

My sexy voyeur. Yes, my love, watch us all you want. It’s only fair. I’ll be watching you from here on out, and my son. Ohhhh…sinful mother.                       

All this time, Billy remained silent, totally passive, almost in a trance as his mother handled him.  Linda also noticed his face had become beet red and his breathing increased as he drank in the view of his naked aunt.

“Everything okay, my love?” She whispered against his neck. Billy nodded, but his squirming increased as she continued massaging every square inch of his cock and balls. Soon, he started to undulate against his mother’s hand. Linda sensed his movement.

Oh, sweet lord.

“Billy, are you about to…”

The next moment, he convulsed, his body spasming as thick ropes of raw cum shot from the tip of his pulsing cock, hitting his aunt squarely on the chin and chest.

“Ahhhg!” Sarah lurched, pearlescent goo coating her pale skin. “Goddamn!” She looked at Billy, then at his mother, awestruck by the sheer amount of ejaculate her nephew could produce.

“Don’t move, Sarah,” Linda commanded. She had a lustful grin on her face. “Let me finish this.”

Cupping her son's balls, she stroked several times from the base to the tip of his shaft, coaxing a few final dribbles of opaque fluid, which ran down the back of her hand. "That's a good son." Linda cooed as she kissed her spent son on the cheek, neck, and shoulder. Then she proceeded to lick the cum from her hand while Sarah watched.

“Let Mama up.” Linda rolled her limp son to the side. “I’m not done cleaning up your mess.”       The next moment, Linda moved over to her sister and started licking cum from her chest.

Billy, although near-comatose, couldn’t help but watch his mother and aunt. “Goddamn, you two.” He couldn’t believe what he was seeing. “Fucking awesome.”

Sarah’s mouth hung open as she watched her sister eagerly clean away the goo, gasping when Linda’s pointed tongue traced around her nipple, then started sucking, all the while savoring the slightly bitter, alkaline taste of semen. Then the other nipple. Linda grasped Sarah’s shoulders as she groomed her like a cat, rising up to clean the cum from her neck and chin. Their mouths interlocked, tongues battling.

“Oh, god.” Sarah whimpered as she pulled back. “Time to fuck again.”

As Billy watched the incestuous tableau, it was impossible not to be affected, and he started to rally. As the minutes passed, his cock began rising and was soon back to full mast. He grasped it in frustration.

“Everyone gets to fuck except me.” He was whining again, but this time, his complaint had merit.

“Oh, honey, I’m so sorry.” Linda, holding Sarah’s face against her pointed breast, reached back to squeeze his leg. It was now her son who was near tears as he grasped his mother’s hand.

“I mean fuck, you and Dolores for all this time, now you and Sarah.” By now, both sisters had sidled up to either side of the young man, their hands on his...
