Sabrina's on the sofa

As Amy and I made our way downstairs, our other sister Sabrina called out from the sofa where she was reading. Sabrina was 22, with short blonde hair and a face full of freckles. She was slender in a way that made it clear she'd done ballet when she was younger, and stacked in a way that made it clear why she'd had to quit. She was wearing a long-sleeved red shirt, and gray sweatpants. I'd fantasized about her more than once.

"Everything okay?" she said, without looking up from her book. "I heard yelling?"

"Uh --"

"I was just bitching John out because of some stupid shit he did," Amy replied. I sighed.

"Ah," Sabrina said, and she sounded a bit disappointed.

"Or do you mean earlier, when he was eating my pussy? Or when I was sucking his cock? Because we were both pretty loud."

Sabrina dropped her book and stared at us. Her face lit up when she saw we were both nude. "Amy! Is that... is that his cum on your tits?!"

Amy smiled proudly. "It is! And I was on the phone with Jenny when he started, and he got her to eat out her roommate!"

Sabrina clapped her hands with glee. "John! It's about damn time! We were starting to think you'd never use us!"

I looked at her. "Then why are you still dressed?"

She shrugged. "You didn't tell me to strip," she said reasonably.

"Let's see those tits, then."

"Sure thing." She got to her feet, peeled off her top, and handed it to Amy, and I grinned with the realization that she wasn't wearing a bra. She pressed her luscious bare tits together and smiled at me. "You like 'em?"

I looked at her D-cup tits covered in freckles, their pale pink nipples swollen stiff. I pinched one; she whined happily, and her hips started moving.

"You're so horny for me already, hm?" I said.

She blinked. "I'm always horny for you," she corrected.

"Huh. Do you think I could... make you cum just by kissing you on the mouth?"

Her eyes widened. Amy laughed. "You're obsessed with making us cum! John, thank you, it's very nice that you care, but your orgasms are what's important."

Sabrina giggled. "Hey, I'm willing to try!"

I grabbed her, dipped her backwards, and kissed her long and hard, my tongue probing deep in to her mouth. Her nails dug into my back. Behind me, I heard wet sounds that were, I realized, Amy masturbating. Sabrina gasped and moaned, clutching at me, then began to shake and squeal. I let go and watched as a wet patch spread across the crotch of her sweatpants. My cock throbbed. After a long moment, she relaxed. "Wow," she said. "I honestly wasn't expecting that would work! Although really, it probably won't be quite that easy next time."

"Can I try?" Amy said. "Uh. John, do you want to watch us try?"

"Sure, go ahead," I said generously. My 20-year-old sister and my 22-year-old sister made out fiercely, kissing passionately as their naked breasts rubbed together, but after almost a minute, they stopped. "Nope," Sabrina said. "My clit is pulsing, but just the kiss isn't enough. I think it was that I've been waiting for you to do this for months now." "Makes sense," Amy said.

Months?!? But I only made the wish an hour ago!

"Anyway," Sabrina went on, stepping out of her sweatpants and peeling off her soaked panties, "are you ready to fuck my pussy now?" She sat back on the sofa and spread her legs wide.

I desperately wanted to say yes. "Uh..."

"Actually, he wants to-" Amy began. "- to fuck Mom first?" Sabrina finished along with her. "Yeah, that makes sense. Which of us do you want to fuck second?"

"Um. Flip a coin?" They both nodded.

"Actually, where is Mom?" I asked.

"Supermarket," Amy replied. "Sab, I thought you were going with?"

Sabrina shrugged. "Decided to stay home in case I got lucky and this was the day John finally decided to use me. And hey, whaddaya know!"

She and Amy high-fived each other.

I made up my mind. "Amy, call Mom and tell her I want her to come straight home. Sabrina, suck my cock."

"Sure!" Sabrina said. She took her shirt from where Amy had dropped it, folded it into a cushion, and knelt on it in front of me. She sniffed my cock. "Hm. I was expecting this to smell a lot more like pussy. Well, I guess it will later!", and with that, she began by licking my shaft from base to tip, then took the head into her mouth and started sucking in earnest. I stroked her face as she worshiped at her new altar; she tried to smile, then continued bobbing up and down.

"I'm calling Mom!" Amy announced. She switched the phone to speaker. It rang three times, then:

"Hello?"

"Mom! Are you done at the store?"

"Yes, I just need to load everything into the car. What's up?"

"He's doing it, Mom! John is fucking Sabrina's mouth right this second!"

"OH!" Mom's squeal was utterly delighted. "That's WONDERFUL! Send me video! I want to see!"

Amy turned the phone's camera on us. Sabrina's tongue was doing interesting things. She had one hand on my cock and the other hand between her own legs.

"Oh, I love that!" Mom went on. "I've been waiting for this since last year!"

"Hey, Mom!" I called out. "Come home so I can fill you full of cum!"

"Oh! Oh, yes, of course! Just let me finish loading up the car! Oh, I'm so happy!"

"Good news?" said a woman's voice that I didn't recognize.

"Yes! My son is fucking his sister's face!" Mom replied. "Look at this video!"

A chill went down my spine and I almost went limp. She was telling this to a stranger?!?

"Oh wow!" said the strange woman. "That's so good of him. Who's holding the camera?"

"My other daughter!"

"Has he done her mouth too?"

"He has!" Amy reported proudly. The strange woman congratulated Amy.

"Uh, mom, who is this person?" I said nervously.

"Oh, just someone who was here in the parking lot. Hello, my name is Emma, and you are...?"

"I'm Karen, nice to meet you. Thank you so much for letting me see this! I know what I'm going to be masturbating to tonight! Well, have a nice day."

What?!? Is she just accepting this as -- ... oh. Right. I guess free-use means nobody gets upset.

Sabrina started humming. Vibrations went through my cock, and a possibility occurred to me.

"Mom?"

"Yes, sweetie?"

"Is Karen hot?"

"Oh, very much, yes. But she left. ... Oh! Do you want her? Should I get her back?"

"Yes! Yes, get her back!" Sabrina kept licking and sucking; by now, Amy had propped the camera on the coffee table and was masturbating again.

"KAREN!" I heard Mom yell. "KAREN, COME BACK! ... okay, here she comes."

"Tell me what she looks like?"

"What is it?" I heard Karen say. "Is everything all right?"

"He's asking about your looks! I think he wants to use you also!"

"OH!" Karen sounded thrilled.

"She's very pretty," Mom went on. "She's Chinese -"'

"Vietnamese," Karen said.

"Oh, I'm sorry. Vietnamese, long black hair that goes just past her shoulders, beautiful brown eyes, some very nice green earrings, a light blue button-down blouse, and - oh, I should have mentioned her tits first. Those look to be a C cup? Really nice ass. And she's, hm, five foot three, and... I'll guess thirty? Thirty-one?"

Karen laughed. "Oh, I love you. I'm forty-one."

"Is that good enough? Will you use her?"

Sabrina was getting me close to the edge, and the realization that I had just gotten my mom to literally grab a random passerby from a mall parking lot and bring her home for me to fuck, was enough to push me over.

"FUCK!" I exclaimed. "I'm cumming Sabrina Mom Amy fuck fuck fuck FUUUUUUUUUCK!" as jet after jet of semen spurted into Sabrina's hot wet mouth. Finally I relaxed, and pulled out. Sabrina gazed up at me from her impromptu kneepad, looking very pleased with herself. Her cheeks were a little puffed up, and a trickle of cum was oozing from her mouth. She pointed at it, wiggled her eyebrows a few times, then held up her hands in a "what now?"gesture. Amy pointed the phone's camera at Sabrina's face. "Swallow," she said. "He likes when we swallow."

Sabrina nodded, and gulped her mouthful down, then licked the last bit off her lips. From the phone, I heard Mom and Karen moan.

"Okay. You're ready to bring Karen home now?" I said. "Yes, John," Mom said.

"Oh, his name is John? That's a nice name," Karen commented. "John, can I drive in my own car instead of riding with Emma? I don't want it to get towed if I leave it here overnight."

I blinked."Uh, yes. Yes, of course."

Mom gave Karen our address, and then offered to let her store her perishable groceries in our freezer, which was another detail that would never have occurred to me if I had grabbed Karen from the parking lot myself. "We'll be home in about 15 minutes," Mom said. "I can't wait to meet you, John! Your cock looks wonderful!" Karen added, and then Mom ended the call.

"In the meantime," Sabrina said, "we should probably all have a quick shower. So we don't start to smell."

"Okay," I said. "You take the upstairs bathroom, and I'll -"

"OH MY GOD!" Amy shrieked.

Her face was pale, and so was her entire naked body. She looked horrified.

I froze - was this wearing off somehow? Was everything going to blow up in my face now?

"John! I'm so sorry! I just realized - you didn't actually say you like it when we swallow! I just assumed! I'm so sorry, please forgive me, I was so stupid! I'm sorry, I'm sorry, I'm sorry!" She sounded like she was about to start sobbing; tears were already starting to trickle down her cheeks.

Holy shit. I glanced at Sabrina - her eyes were wide, and she was shaking like she might pass out.

"Amy! Amy, Sab, relax! Relax, okay? I do like it when you swallow!"

Sabrina exhaled, and collapsed onto the sofa. "Christ, don't fucking terrify me like that!" she muttered.

Amy's lip was quivering. She sniffled, and wiped her nose. "You... you promise? You really do?"

"Yes, I promise. It's super hot that you love my cum so much you want to swallow it!"

Amy looked troubled.

"...Amy?"

Sabrina cleared her throat. "What Amy's trying to avoid saying is, we don't love it."

"What?"

"John, I assume every guy's cum tastes a little different. I've only sucked two guys before you, and I'm not gonna suck anyone else ever unless you tell me to, so I don't know how much of a range there is, but... I mean, you're not that bad, but you're not that good either. I guess if I loved the taste, I would've swallowed without needing Amy to tell me. Sexy and hot, yes. Delicious... not so much."

"...oh."

"Don't worry!" Sabrina said hastily. "We'll keep swallowing whenever you want to cum in our mouths!"

"It bothers you that we do it but we don't like it?" Amy asked.

I scratched my head. "Um... a little?"

"But that shouldn't matter!" Sabrina argued. "We still love that you use us! It's like, if you're fucking me in a weird position and I get a leg cramp! I wouldn't love that part of it, but it's still you using me, so that makes it okay!"

"Yeah, but it feels... kind of mean, maybe? I wouldn't want you to get a cramp!"

"Yeah, but -"

"Oh wait!" Amy said, holding up an index finger. "I know what we can do!"

"...yeah?"

"Earlier, you told Jenny to love eating pussy, and now she does! You can do that with us! Tell us to love the taste of your cum!"

"... huh. You think that'll work?"

"Worth a shot," Sabrina said. "Tell Amy to love the taste of your cum, but not me. And then after you fuck Mom, we'll both lick it out of her, so we can see if it really makes a difference or if it's just a placebo effect. Sound good?"

I nodded.

"Okay, great. Let's go have those showers."
