Self medicated OD

Ophelia fends off her sister’s weak and unenthusiastic attempts to fight her sister off. Juliet would love nothing more than to let her sister do whatever she wanted with her body. They both knew from this was where everything was going anyway, so after a bit of at least pretending to fight off her sister’s advances she finally let her own horny side take control.

“Don’t worry Juls. Just lay back I’ll take care of everything.” Ophelia said. Juliet was almost hypnotized by the amount of lust in her bedroom eyes peering back at her from between her thighs. A light kiss on her inner thigh. Closing her eyes, Ophelia began placing small loving pecks trailing up her leg causing the sound of ripping fabric to come from Juliet’s crotch. The panties didn’t last long as Juliet moaned before the small crotch cover was ripped open by the fat cock within which, now free of it’s meager prison, instantly stood tall and pushed the hem of the skirt it was under up and out of it’s way.

Ophelia would not be detoured as she glanced at the meaty slab before returning to her foreplay. When her lips finally met the Scrotum she inhaled deeply as the heavy scent. It’s perverse smell causing her to worship it more. Her tongue lathered the hairless orbs and the taste was sending her libido into a tailspin. These delicious and magnificent balls were her new salvation. As she played with them something caught her attention. Were they growing? She placed the balls in her hand like two mandarin oranges and gasped before dropping them.

“What? What’s wrong Lia? Is something wrong with me? Oh no I had a bad reaction to something didn’t I? Ohmygod ohmygod we gotta call the doctor and…” Juliet continued her freakout as Ophelia watched the balls expand before her eyes. They stopped growing when they looked like proper oranges.

“Juls calm down. I you’re fine. I think your new genetics are taking effect. Look.” Ophelia says as she holds one of her sister’s nuts in her hand. “It’s so big. I bet it’s just bursting with cum… and it’s all for me.”

Juliet looked at the not bloated sack and placed her hand on the other testicle. “Woow. It feels so hot…. Like temperature hot not sexy hot. Well sexy hot too actully. The doc did say my balls would be able to keep you fed for a whole day eventually… maybe they’re getting a kick start since the allteration is still somewhat fresh… I’m so hungry now too… i feel like I could… uhhhhh!” Juliet didn’t finish her thoughts as Ophelia began taking the dick into her mouth and massaging her balls as if trying to coax them into growing larger.

Ophelia just couldn’t wait. Her thirst was really starting to get to her and she needed a dose soon. Though with her new job she was a little out of practice as her sister’s long fat cock hit the back of her throat she immediately gaged and felt tears fill her eyes “Gggkkk!” but like a true cum hungry slut she didn’t take the meat pole out of her mouth and simply tried again. And again, and again. Over and over and over she kept slamming her face forward in countless attempts to throat the massive beast.

“Lia stop! Your hurting yourself!” Juliet said as she tried to push her sister off her cock. The constant kneading of her balls and stimulation of a tight throat spasming on her bitch breeder caused the orbs to build a heavy reservoir of cum inside them. They were now the size of small melons and weighed about the same. “Please Lia… soo hungry… I need food…”

Ophelia finally relented and slurped her saliva off the coock exiting her mouth. Since technique wasn’t working she’d have to pull her trump card. Self-degrading sexy talk“And I need cum. I need it so bad Juls. Your whore of a sister needs you to bust a hot load of bubbling hot cum into her belly. Feed me and I’ll feed you. Fill me up until I can’t speak without burping up your sister-seed. **** me to take your fat commmph! Glk glk glk glk”.

Juliet couldn’t take it anymore. The way her sister talked, she needed to silence her the only way she would understand. So she grappled with her hair and yanked her face down onto the shaft again, using her head as an onahole. “Fine you fucking cum starved slut. I’ll fill your belly and then I’ll fill mine.” Ophelia agreed and furiously slammed herself up and down Juliet’s thick pole in the sole attempt to get her to climax, no pleasure just release, the problem was she was using her sister exactly the way she liked being used.

A pair of hands grab and squeeze Juliet’s tush, rolling the thick muscle under her fingers, Ophelia was merely trying to steady her self as she was fantasizing about being like nothing more than a sex doll. To be nothing more than a hole for her sister’s jaw stretching, neck bulging, stomach filling cockmeat. The musk, the sweat, the cum… all so sinfully delicious. Then it happened.

Juliet felt her release cumming. Her dick swelled and she felt Lia’s jaw pop as it did causing her maso sister to moan long and hard around the fleshy plug in her neck. She felt her balls try to pull up but they were so heavy with cum they barely moved as the first spurt blasted down the tube and straight into Lia’s stomach.

Ophelia felt the crack of her jaw and her throat was suddenly too small for the monster she had encased in it. And then the first of many pulses crashed into her stomach like a high pressure hose spraying into a bucket. She immediately felt full… but not satisfied . She wanted everything. EVERYTHING! She felt the second shot hit and the waist of her skirt got tighter. Another shot, tighter still. Another , *ting* the small aluminum clasp failed and flung across the room as one of Ophelia’s hands found her belly. The next shot came and she actully felt her skin stretch and he belly push further outward. Her fingers spread out as her bulging gut filled her lap. This was it, this was the dream existance, to be her sister’s cum balloon. She had thought about it, masterbated to it, found art and pictures and stories online about it but now it was happening and it only made her hold on tighter.

“Lia… uh, stop… it’s too much…guh, too much… let go… I can’t.. HUUUU stop cumming…” Juliet. couldn’t see her sister getting stuffed like a turkey but she knew that she was cumming too much for a normal climax and wasn’t sure how to stop.
