Sarah gasped for air watching her breasts rise and fall as she leaned back in her after glow. Her eyes drifted between her four spent dicks and her little sisters softening behemoth cock. The site repulsed her deeply wishing only to be rid of the phalic growths, her own and the one on her sister!
She briefly noticed Amy take her phone in hand and begin to tap at its screen. She was out of her mind! She'd just been fucked by her four spontaneous dicks and sprouted a giant dick herself! And she was playing with her phone? Now? Of all things!
That wasn't too unusual though' Sarah thought. Amy always enjoyed taking pictures of her after sex. They'ed been doing this for years really. It was always such a hassle when they still lived with their parents, but once they'd moved out they were at their own leaguer to fuck.
Amy put down her phone and gave her a playful kiss in the air. This had long since been their way of saying they wanted another round. She gave the corresponding wink and Amy lifted herself off her seat.
She walked over slowly, fanning out her two pairs of arms and flexing them about as though noticing them for the first time. She came to neal before Sarah, who spread her legs wider to offer up her bounty of cocks.
Sensually each hand came to grasp one cock each. Fingers gliding over the tips to smear her residual juices fully ally into her grip as she started to pump. Each hand moved in the same speed but at different points working her arms like pistons in an engine.
Sarah leaned her head back with a soft moan vibrating in her throat. The motion of this hand job always sent her into high speed. Each cock surged forth becoming rigid and firm, peak performance.
Sarah was soaring in bliss when it stopped abruptly. Almost frustrated with the sudden hult she snapped her head down to watch Amy fondeling her 2nd pair of breasts. Bizzarly Amy seemed really into it. Bouncing them up in her hands, examining their firmness and spring.
"You okay sis?" Sarah asked. "You take something?"
"Uh, no..." Amy stuttered, not removing her hands from her breasts. "Just, really turned on right now..."
Amy bit her lip and moaned. Only the sound came from her four breasts. Specifically the lips that sat perked up on each one like nipples.
"Good! You always give the best titty-sucks when your really horny."
Amy leaned forward and each lip toped breast opend to engulf one cock head each! The tongues masterfully swirled over the tips. Each breast struggling to find the room to fully take in a cock against their pressed girth.
Amy panted from the effert of pushing her four breasts togther and leaning in and out to thrust her chest onto the leangths. Sarah cried faintly from the quad-suck and she quickly began to ple to her sister.
"Amy, um so close! I'm going to... to..."
"Oh no you don't." Amy teased, pulling herself up and with four audible 'plops' released her sisters cocks from her lipples. "Not with me having my fun!"
She stood up one pair of hands cupping her breasts, and the other pair reaching down to hold her massive arcing erection!
Sarah waisted no time leaning back and lifting her legs! Placing her own hands between them to lift her balls revealing her dripping pussy to her little sister.
With no cerimony Amy guided her fat leangth into her big sisters sopping folds. She moaned deeply as she slowly guided it in. Giving the sexual organ time to stretch over her girth. With two hands on he thighs, and another two on her waist Amy trusted her cock in and out of her sister. Each stroke guiding her imposablely deeper and deeper until she was almost buryed to the hilt of her 11in dick.
As the thrusting picked up Amy grew closer to climax. Sarah always knew when this was coming as Amy would shift her grip. She began pulling further out and prodding closer behind her cock'd with her own swelling head. Each jab tapped at her four prostates and Sarah quickly cam from her four cocks!
Ropes of cum sprung from her cocks drenching her belly and Amy's breasts in pearly white jizz. Amy's lipples lapping at her under breast to taste her salty seed! Amy came shortly after adding to the climax as forceful jets of steaming spunk emptied into her pussy.
Spent from the exchange Amy withdrew and leaned over her sister before flopping to her side on the couch. Sarah fell over onto her sisters side in a soft panting cuddle.
Sarah came to se time later. Not much later, five or ten minutes she though. Amy was asleep next to her and she remembered the fun she'd just had with her sister. With her hornyness subsiding she was thing clearer. And she came to realize she was a mess. Covered in her own cum and dripping her sisters between her legs she was overcom with the urge to clean herself.
Without aweakening Amy she got up and headed for the bathroom. As she passed the couch opposite her though she spotted Amy's lit up phone.
"Huh? Chroni-app? What's this?..."
