Secret Sister Nights: Taboo Oral Awakening

The dim glow of the bedside lamp flickered as Andy stirred in his bed, his head pounding from another night of heavy drinking. At 21, he was home from college for spring break, sharing the family house with his older sister Jill, who was 24 and back from her own studies. Their parents were away on a week-long anniversary trip, leaving the three siblings—Andy, Jill, and their youngest sister Jenna, freshly 18—to their own devices. What started as casual nights of beer pong and laughter had twisted into something far more mysterious.

Andy sat up slowly, rubbing his eyes. His boxers felt sticky again. Dried semen crusted against his skin, and a dull soreness throbbed in his groin. This was the third morning in a row. He had no memory of jerking off or hooking up with anyone. The house was quiet except for the distant hum of the air conditioner. Down the hall, he could hear Jill humming in the kitchen, making breakfast like nothing was wrong.

He showered quickly, mind racing. Was he blacking out and doing things in his sleep? Stress from finals? He decided to test it. That night, after they polished off a case of beer and a bottle of cheap vodka, Andy pretended to pass out hard on the couch. Jill helped him to his room, her strong arms surprisingly gentle as she tucked him in.

"Goodnight, little bro," she whispered, her breath warm against his ear. He kept his breathing deep and even, eyes closed but senses alert.

Minutes stretched into what felt like an hour. Then the door creaked open. Soft footsteps padded across the carpet. The mattress dipped as someone sat on the edge of his bed. Andy's heart hammered, but he forced himself to stay limp.

Fingers, delicate yet confident, tugged at the waistband of his boxers. Cool air hit his cock as it was freed. He fought not to twitch. Then, warm wetness enveloped him—lips sliding down his shaft in one smooth motion.

Holy fuck. Jill. His own sister.

Her mouth worked him expertly, tongue swirling around the head before taking him deeper. Soft sucking sounds filled the room, mixed with her quiet, hungry moans. She bobbed slowly at first, savoring him, then faster, her hand stroking what her lips couldn't reach. Andy's toes curled, but he kept the act going, pretending total unconsciousness while pleasure built like a tidal wave.

Jill hummed around him, the vibration sending shocks up his spine. She cupped his balls gently, massaging them as her head moved with practiced rhythm. The taboo of it—his big sister sucking him off while their little sister slept down the hall—made it impossibly hotter. He came hard, spilling into her mouth without warning. Jill swallowed every drop, licking him clean before tucking him back in and slipping away like a shadow.

Andy lay there afterward, cock still twitching, mind blown. He should have been furious. Instead, a dark thrill coursed through him. He wanted more.

The next night, he "drank" even heavier, making a show of it. Jill's eyes sparkled with something unreadable as she matched him shot for shot. Jenna, the innocent-looking 18-year-old with long blonde hair and a cheerleader's body, watched them both curiously but said little. She had just turned 18 two months ago and was still navigating her first year of freedom.

Again, Andy feigned blackout. Jill returned. This time, she was bolder. She stripped his boxers completely off and spent nearly twenty minutes worshipping his cock—kissing the shaft, licking his balls, deepthroating him until her nose pressed against his pubic bone. Her free hand disappeared between her own legs; he could hear the wet sounds of her fingering herself. When he exploded, she moaned loudly around him, cumming too.

He started craving these secret visits. During the day, he acted normal—teasing Jill about her college stories, playing video games with Jenna. But at night, he became her willing victim, hips subtly thrusting up when she sucked him, though never enough to break the illusion.

On the fourth night, something changed. Andy heard two sets of footsteps. The door opened wider. Jill's voice, barely a whisper: "See? He's completely out. Watch this."

Jenna's soft gasp. "Oh my god, Jill... you're really doing it."

"Shhh. Just watch, baby sis. He's so big when he's hard."

Andy cracked his eyes the tiniest fraction. In the moonlight filtering through the curtains, he saw Jill on her knees beside his bed, his cock already in her mouth. Jenna stood a few feet away, one hand pressed between her thighs, biting her lip. The younger sister's shorts were pushed down, fingers circling her clit as she stared transfixed at her brother's shaft disappearing between Jill's lips.

Jill put on a show—sloppy, noisy, pulling off to stroke him and whisper filthy things. "His cock tastes so good, Jenna. You have no idea how much I need this."

Jenna's breathing grew ragged. She slipped two fingers inside herself, pumping in time with Jill's bobbing head. Andy's pulse thundered. This was beyond his wildest fantasies. His sisters, both beautiful in different ways—Jill with her athletic curves and confident smirk, Jenna with her fresh-faced innocence now cracking into raw lust—were using him as their secret toy.

When he came, Jill took it all, then turned to Jenna. "Your turn to taste something."

Jenna hesitated only a second before dropping to her knees in front of Jill. She pushed her older sister's skirt up, revealing no panties and a glistening, shaved pussy. Jenna leaned in, tentative at first, then eagerly licking. Jill gripped her little sister's hair, guiding her tongue.

"Fuck, yes... right there, Jenna. Lick your big sister's clit."

Andy watched through slitted eyes as Jenna devoured Jill with surprising enthusiasm, her own fingers still working her pussy. Jill came hard, thighs trembling, muffling her cries against Andy's thigh. The sisters kissed afterward, sharing the taste of both of them, before quietly leaving.

The household grew thick with tension after that. During breakfast the next morning, Jenna could barely look at Andy without her eyes dropping to his crotch. She kept asking innocent-sounding questions that dripped with subtext: "So, Jill, what are your plans tonight? Any more drinking games?" Her cheeks flushed constantly. Jill tried playing it cool, suggesting they "cool off" to avoid their parents returning to a suspicious house. But the looks between the sisters told Andy they were both hooked.

He decided it was time to push things further while keeping the "sleeping" pretense.

That afternoon, while Jenna was at the mall, Andy cornered Jill in the laundry room. "Hey, I've been having weird dreams lately," he said casually, watching her reaction.

Jill froze for a split second, then laughed it off. "Probably the alcohol, dummy. Why?"

"Just... feels really good in those dreams. Like someone's taking care of me." He let the words hang.

Her eyes darkened with lust, but she kept composure. "Maybe you should lay off the drinking then."

But that night, the drinking continued. Andy passed out dramatically again.

This time, both sisters came together earlier. They whispered plans right beside his bed, thinking he couldn't hear.

"He's so hard already," Jenna giggled softly. "Can I try tonight?"

"Only if you're quiet," Jill replied. "We can't wake him. This stays our secret."

Jenna's small hand wrapped around his cock first. She stroked him experimentally, then lowered her mouth. Her technique was less skilled than Jill's but eager—lots of tongue, gentle sucking, exploring every inch. Jill coached her in whispers: "Deeper, baby. Use your throat. He loves that."

Andy struggled not to groan. Jenna's mouth felt incredible—hot, wet, and trembling with nervousness. Jill fingered Jenna from behind while she sucked, making the younger girl moan around his shaft.

They switched. Jill took over, deepthroating him while Jenna sucked on his balls. The dual sensation nearly broke his act. He came explosively, and both sisters shared his load in a messy, tongue-filled kiss right next to him.

Afterward, they didn't leave immediately. Jill laid on the bed beside him, pulling Jenna on top of her. The sisters made out passionately, grinding against each other. Jenna rode Jill's thigh while Jill's fingers plunged into her little sister's tight pussy. They came together in hushed, shuddering orgasms, bodies pressed close enough that Andy could feel their heat.
