Barely

You grab your coat and sprint out to the parking lot. Moments later, you pull up to the door of the restaurant just as Nicole is pushing Sara out the door. The two girls tumble into the backseat together and when the door closes, you peel out.

Nicole pipes up: "Jesus, John. Her condition is pretty bad. She was starting to ask me if she could blow the waiter."

"And you wouldn't fucking let me, you greedy bitch. I bet he could shoot a huge fucking load," said Sara. Glancing in the rearview mirror, you could see the sweat pouring down her face and running down her neck and disappearing into her cleavage...

"Fuck, we need to get her a dose quick," you say, jerking the wheel to the right to avoid a pedestrian. Stop staring at her tits and drive, asshole.

"So why won't you give it to me, John? Your cock is so fucking big, and your cum tastes so fucking good. Why the fuck are you up there driving the stupid car instead of back here letting me deepthroat your big dick? Please? You can fuck my little pussy if you want. You can fuck my little pussy right in front of my sister," Sara moans, and you can see her hand is back under her skirt.

"John! John. She's... she's masturbating. Is that normal?" asks Nicole.

"Yeah, baby, that's normal. It just means she really needs to get some semen as soon as possible. It's just another symptom. The more she needs to get it into her system, the hornier she'll get. It's the body's way of trying to fight the disease--it makes the afflicted crave cum so she'll be more likely to get it."

"Oh, fuck, yeah, gimme your cum, John. Please? I'll be such a good little slut for you. Fuck... uhhhh... Hey! Do you think that old guy on that bench would let me suck his dick?" asks Sara. "I'm gonna ask him!" As she reaches to lower the window, Nicole starts to fight her hand away from the window control.

"John! Hurry, please! No, honey, that homeless guy won't let you suck his dick," she lies to her sister.

"Why the fuck not? I'm hot! And I suck dick real good, right John?"

"That guy was obviously gay," you say, making the turn onto Sara's street.

"There's her building!" shouts Nicole. "Sara, we're here. We just need to get upstairs and John will give you a huge load of cum, okay?"

"Yeah, right." Sara replies, her head starting to loll over. " You're probably gonna try to hog it all. You want his cum, don't you. Admit it, you whore."

You pull the car into a spot in front of the building, and Nicole jumps out to pump quarters into the meter. She shouts for you to get Sara out of the car and get her upstairs. "Apartment 4D! The key is in her purse."

You open the back door, take the keys out of her purse, and scoop Sara into your arms. She can barely keep her eyes open at this point, but she continues the litany of filthy incitements to give her your cum as you unlock the door to her building.

"Please, John. Lemme be... lemme be your cumdump. I'll be a better whore for you than my sister. Any time. Any place. Any hole you want," she says as you open the door to the elevator.

"You can fuck my asshole, John. Please fuck my asshole. Please give me your dick. Your big fucking dick belongs in my tight little teenage holes. I know you like my titties. My big fat titties. They're yours. Forever. I promise. Just please blow your fucking hot load in my mouth," she says as you ride up to her floor. Sara works her hand down to the front of your jeans and is stroking your bulge.

"My body is yours. My throat. My pussy. My asshole. My titties. I'm yours. I'll be your ****, John. Please. I'll eat every load you make in those big heavy balls. Please let me be your fuckslave. Your cumslave. Your little teenage cumwhore. Just give... me... your cum," she whispers into your ear as you manage to unlock the door to her apartment and carry her inside. You unload her onto the couch, and quickly start to undo your pants.

Sara can barely move at this point.

"Please... give... me... your... cum. Please... give... me... your... cum. Please..."

You start stroking your cock, and a few moments later, Nicole runs in the door and slams it behind her.

"John! You need to cum!" she yells.

"I know, baby. Just give me a second!"

"Let me help!" yells Nicole, and without a second thought, she rips off her top and her sports bra, revealing her sizable DD tits. She grabs your cock and slams her open mouth down it until you hit the back of her throat. She holds herself there for a few second until her pale face turns as red as her hair. She pulls her face off your dick, breathes loudly, and then says words you'd never thought she'd say to you. "Fuck my throat as hard as you can. Fuck my face. Please. Just cum as quick as you can."

You can't resist an invitation like that. And so you grab your girlfriend's red ponytail and really fuck her throat hard. You press her nose against your pubic bone and feel Nicole's throat muscles convulse and twitch around your cock while you stare at Sara's body on the couch. Realizing that Nicole can't see what you're doing with your other hand, you reach over her back and start mauling Sara's giant tits.

The thought fills your mind: It's practically a threesome with both sisters.

At that, you feel your balls start to boil, and you pull Nicole by hair back enough to completely fill her mouth with your cum. When her mouth gets completely filled, you pull out and pump the rest of your hot load onto Nicole's face.

"Now give it to Sara, quick," you explain to her as her wide eyes question why you came in her mouth instead of her sister's.

Nicole nods, and scrambles to the couch. She grabs Sara's face and begins spitting your cum into her mouth.

As your load starts to coat Sara's tongue, her eyes open. She reaches up and grabs Nicole's head with both hands and starts to furiously make out with her older sister. Sara's tongue hungrily searches every crevice of your girlfriend's mouth for every trace of your cum. Once Nicole's mouth is cleared, she pulls back and licks Nicole's face clean, careful to get every last drop of sperm.

"Fuck, Nikki! I needed that so fucking bad," says Sara. She then reaches out, grabs your cock and gives it one last stroke, coaxing out one last drop of cum to appear on the tip. She licks it off.

"Oh god. I really fucking needed that. Thank you guys so much. Both of you. I'm so sorry," Sara says, as tears fill her eyes. "This is so horrible, and you guys are being so generous. I just feel so helpless!"

Nicole answers quickly, the shock of swapping your cum with her baby sister seeming to fade in the face of her sister's emotion. "Saracakes. You're my sister. I will always do anything and everything I can to help you. And since John is mine, he'll do anything for you too. It's not trouble. It's family. Now come on, let's pack up your things."

Nicole slips her shirt back on and pulls Sara back into the bedroom as you collapse onto the couch.

What a fucking day.
