Just as Mollie and Justin were getting cozy on the couch, the doorbell rang.
 
"I'll get it!" echoed the voice of Mollie's sister Anya, who came bounding across the living room. Her sizable mammaries heaved as she approached the door. Before she opened it, she shot them a conspiratorial glance. "Oh, hey Justin, didn't realize you were over." He waved with his spare hand, while Anya opened the door and escorted her guests inside. It was a young couple, a dark-haired boy in a sharp outfit and a tallish girl whose hair had been precisely styled into little blond ringlets. "Come in, come in!" said Anya, kissing both of them on the lips. With a bounce in her step (and more), the pixie-like host escorted the couple toward the back of the house. Justin snuggled closer to Mollie, trying not to let on how much he enjoyed the view. After all, Mollie had very beautiful breasts of a more comfortable size, which were presently pressing against his upper arm through her fitted top. And, judging from the sensation, she wasn't wearing a bra.
 
"Is Anya dating one of them?" he asked his girlfriend in a whisper. "He's different than the boy she had over last time."
 
Mollie rolled her eyes. "Knowing Anya, probably both of them. Her last boyfriend ended up melting away in her snatch on the second date. I wouldn't be surprised if the two of them were pushing up her bra size by the time you go home tonight."
 
Justin squirmed, sliding his hand to rest on Mollie's thigh. "Seriously? She works that fast?"
 
Mollie shook her head, more in disbelief at her younger sister's antics than anything else. "Yeah, and she lords it over me all the time. Like, 'Unlike some people, I go all the way. That's what they really want.' I dunno where she finds them."
 
"Maybe we should see just how far we go tonight, huh?" Justin whispered into Mollie's ear as he rubbed his face against hers.
 
"Ha! I'm starting the movie before you forget why you're even here," she teased, grabbing the remote and pressing play.
 
But of course, the movie wasn't truly why Justin and Mollie were snuggled up on the couch. As the movie played on, his hand worked its way up her thigh under the blanket, until it was teasing at her panties. Mollie squirmed and shifted, and soon the panties were sliding down her legs to the floor, Justin's right hand tasting the hot wetness of her slit. Gently, he worked his middle finger deeper, soon adding a second finger and even a third as he massaged the welcoming depths of Mollie's lower mouth.
 
Right as Mollie was beginning to lose her strict control of the noises she made, letting a pleasure-saturated whimper escape her lips, a similar but much louder noise filtered up from the back of the house. "Fuck, there she goes," Mollie hissed out between labored breaths. Justin just grinned in reply and worked Mollie's pussy harder, so that a moment later it had gulped up his whole hand and the moist inner flesh was working its way up past his wrist.
 
"Since we won't have to worry about being interrupted..." Justin began. He let his actions finish the sentence, as he shifted to the floor in front of the couch, completely under the blanket with Mollie's legs spread to either side of him so that he could start working his other hand up into her snatch.
 
Noises from down the hall, recognizably Anya's ecstatic voice, continued to filter in while Mollie increased her own moaning. With a practiced ease, Justin slipped his left hand inside of Mollie and gently thrust his forearms in and out, pushing a little bit deeper each time. Before the movie was even halfway over, Justin was tasting Mollie's delicious nectar with his arms completely submerged. Mollie took a deep breath as he pushed his head into her waiting snatch, letting her labia slide past his armpits and down to his shoulder blades.
 
Now stretched past Justin's widest, going was easier, and Mollie greedily welcomed Justin's thrusts, gradually slipping past his ribcage. She savored the feeling as the contours of his tensed abdominal muscles rubbed against her inner flesh. Mentally, she congratulated him for being so slick she hadn't even noticed when he had taken off his shirt.
 
Mollie was slouching lower and lower off the couch in order to reach further down Justin's torso. He had relaxed his efforts with his upper body for a moment in order to try and disrobe his lower half, using one foot to pull the pant leg off the other. Mollie helped him, now easily in reach of his waist buttons, and got the process started as she yanked his throbbing member out.
 
She massaged his erect rod a little with her hand, but pretty soon it was time to jam it into her hungry passage. Justin had gotten his pants off completely now, so he was eagerly pushing up into Mollie's love canal with his knees. Mollie could hear his voice, muffled but clearly saying, "Yeah, yeah, fuck yeah, oh god," and the like from somewhere in her distended belly. Around the time that he clenched his whole body tight, Mollie slipped unceremoniously off the couch and thumped to the ground, lifting Justin's feet off the floor with only his ankles protruding from her sex. The feeling of his seed flowing out inside her set Mollie over the edge, and her insides tugged his feet the rest of the way. Mollie grabbed around for Justin's boxers and used the fabric to wipe away her own lady-seed from the opening between her legs. Her outer lips had receded down back to their original size, although her belly was still swollen from having a full-grown lover engorged in it. Carefully, Mollie lifted them back onto the couch and lay back to relax.
 
"That was fantastic," was the first proper sentence Justin spoke after regaining his composure, such as it were with his entire body located somewhere in the vaginal passage of his girlfriend.
 
"Mmmmm hmmmm..." she replied, rubbing her stretched abs and shifting around to lay on her side, where she could see past her stomach. Justin, too, shifted, which satisfied Mollie quite nicely. She was too exhausted to get totally turned on again, but it was relaxing to cuddle with her boyfriend inside her.
 
"I'll just... take a nap, I guess..." Justin suggested, and no sooner had he finished the sentence could Mollie hear his gentle, rhythmic breathing filtering up through her torso. She ran a hand along the bulge from his body and lay back, looking back at the movie.
 
She watched the last hour or so of the movie with half interest. It was hard to piece together what was happening all the time, since she'd been preoccupied for most of the first half. She was thankful there were no more noises from Anya's room. By the time the credits started rolling, she shifted around and squeezed Justin to wake him. "Alright, time to go."
 
He stirred slightly. "Awww.... c'mon, just 5 more minutes?"
 
"Ha ha. Sorry, I'm getting pretty tired, too. You know that I can't hold off the digestion process forever. If you stay in there any longer you might not make it out."
 
"Whatever," he replied blearily, shifting slightly like a kid rolling over in bed.
 
"Come on... I don't wanna digest you, Justin!"
 
"That's fine..." he mumbled, still not getting into it.
 
"Justin, it's not fine," Mollie replied, squeezing again, hard enough that it probably actually hurt. That seemed to wake him up. "Let's go," she urged.
 
Somewhat reluctantly, Justin uncurled himself so that Mollie could push him back out of her snatch, which went smoothly and was almost as nice as the trip in except that they were both tired. Justin sat on the blanket and collected his clothes, slipping back into his T-shirt and the boxers that were soiled with Mollie's emissions.
 
"Shower time?" Mollie offered, but at almost that exact moment, they heard a door shut from further in the house, and seconds later the sound of the shower being turned on. "Aww, dammit. Anya beat us to it."
 
"That's fine," Justin said mellowly, slipping his jeans back on despite still being doused in Mollie's juices all over. "I can do it later. I should get going."
 
As he stood, they shared a groggy kiss in the doorway, while Justin fumbled into slipping on his shoes. "Are you going to be OK to drive home?" Mollie asked with slight concern.
 
"Don't worry about me," he said, and waved after he stepped out.
 
Mollie was pretty tired from all that exertion, too, so she stumbled back to her bedroom and nodded off. She awoke late in the morning to her phone ringing.
 
The number looked familiar, but she didn't have it in her contacts. "Uh... Hello?"
 
"Hi. Mollie? This is Justin's mom..."
 
"Oh, uh, hi there." Suddenly Molly was a lot more awake, her heart racing from shameful nervousness. How much did Justin's mom know about their relationship? "Hey, uh, I just was wondering, is Justin still over there... with you?"
 
"Huh? No, no way! He took off, like 1am last night!" Mollie stammered out awkwardly, her shame turning to concern. "Did... he not come home?"
 
"No, his car's not here, either. But I guess... that means you didn't, er, keep him, either?" The awkward, shy tone from Justin's mother made it clear what she was implying, and Mollie turned beet red just from the idea that Justin's mother was considering it.
 
"N-no! I could never..."
 
"I see... well, thanks, Mollie. I guess call me back if you figure out where he is. You have my number now?"
 
"... yeah. OK, bye..." At this point, Mollie had gotten up and made her way to the front door, to look out at the driveway as if Justin might turn up randomly any second. But of course he wasn't there.
 
"Looking for someone?" Anya's voice had a sly, singsong tone. Mollie whirled around to see her younger sister, wrapped in a towel, standing at the end of the hallway. Anya's breasts threatened to overflow the towel any second, partly because they were pressed up over Anya's folded arms as she leaned against one wall grinning. Anya's shortish hair wisped in a few directions, making it clear she, too, had just woken up.
 
"It's Justin. He didn't go home last night."
 
"Yeah, I know."
 
"You... Do you know where he is?" Mollie's heart palpitations were only getting stronger, and she could feel her face getting more flushed by the second.
 
"Oh yeah. More or less anyway." She grinned nonchalantly, unfolding her arms to circle a finger around one breast, then the other. "Little bit here, little bit there... some more down below."
 
Mollie charged. "You didn't. You did not seriously digest my boyfriend."
 
"Well, technically, I don't think he was your boyfriend at the time. He told me he'd given up on you." Anya kept her calm even as Mollie cornered her against the wall. "When he begged me to absorb him."
 
Aside from her more modest bust size, Mollie was the bigger one, and she leaned in over Anya's face in apoplectic disbelief. "No fucking way. You... Justin wouldn't..."
 
"He seemed pretty frustrated you would never go all the way with him." Anya was grinning smugly. "I told him I would be glad to, when he circled around to my bedroom window last night after you rejected him."
 
Mollie's fuming anger was turning into desperation. "No... He wouldn't... You have to... let him out. Give him back. He can't leave me!" Although she still had Anya pinned against the wall, she slumped down, her hands curled into fists as her forearms pressed meekly against Anya's shoulders. Then, realizing something, she tensed up again. "All that noise you made last night while he and I were together... that was on purpose!"
 
"Of course it was, dear big sis. I was inviting him. I saw this coming, since reading the disappointment on his face weeks ago. I knew. So I thought, if you still won't give him what he wants, I don't mind doing it. He always was kind of cute."
 
Mollie was beyond words. She grabbed Anya by the shoulders and squeezed, shaking her while trying to stammer out something besides "Augh!" between venting frustration and the tears welling in her eyes. Anya's towel slipped, and she let it fall to the side, catching it casually in one hand.
 
"You're making me feel kinda bad, sis. I didn't think you'd be this distraught over a boy you rejected." Anya had maintained her composure, so it was difficult to tell how sincere she was. She slipped a hand forward to undo the drawstring at Mollie's waist and let her sister's pajamas fall off. "Tell you what. You pretend that I'm Justin and I'll recount his final moments." She slid her hands back up Mollie's hips to lift the pajama top off her shell-shocked sister, leaving them both naked. "I'm sure Justin would be pleased to end up a part of you after all. If you can actually finish the job."
 
Mollie was locked up like an overloaded computer, as her younger sister led her by the hand down the hall. "It starts in this room," Anya narrated, "as I heard a knock on the window. I had just gotten in, fresh from the shower." She wrapped the towel she'd been wearing loosely around her sister, then rapped lightly on the window from the inside. "Hello?" she voiced in a surprisingly good impression of Justin, "Hey... Anya?" The absolute, self-deprecating shyness of Justin's tone was evident in her retelling.
 
"That's when I slid the window open and smiled. 'Hey Justin,' I said. Go on," she urged Mollie to play along.
 
Mollie repeated the dialog, but her thousand-yard stare made it clear her mind wasn't in it. "Hey. Justin..."
 
"So I helped him in, and this is no surprise, but he was completely slick and covered in the rich flavor of someone's pussy." Casually, Anya dipped her whole hand in between Mollie's legs to punctuate her point. Mollie hardly reacted. "I couldn't help but lick a little bit of the flavor off my hand after helping him up." Anya pantomimed lifting climbing in through the window, then offered her hand to Mollie to lick the flavor of Mollie's nethers off of it. Mollie brushed it away, so Anya brought it to her own lips and licked her sister's flavor off her own hand sensously, as she must have done the night before.
 
"Of course, I made sure Justin could see the clothes of my earlier dates still strewn about the room," Anya continued, "And I had been sure to give him an eyeful of my cleavage when I helped him in. I was feeling extra jiggly after adding some fresh weight to them earlier...
 
"Damn," Justin surveyed my room, "So it really was true, huh? You gurgled them both already..."
 
Of course, I smiled back and helped him out of his cum-smeared clothes. We both knew what he was here for, even if he still hadn't realized I knew. "Of course. That's why they were here. I took her first, then let him dive in after her as if he could rescue her. Then they fucked like crazy inside me until I finally melted and swirled them together, just like their Predplace profile requested. It was a pretty good night... but I usually prefer the ones I know a little better." He shivered as I ran my finger up his chest to his chin, you know?
 
During her narration, Anya had somehow coaxed Mollie into sitting on her bed, and she slipped the towel back off her sister while tracing a finger up from Mollie's trim little belly-button between her modest breasts and to her chin. Evidently Anya had pivoted roles back to being herself in the scenario, while Mollie had become as compliant as Justin. Anya cradled her sister's chin between finger and thum, then leaned in for a kiss, which Mollie returned with lots of tongue, letting a little saliva spill out between their mouths when Anya pulled back.
 
"You know, sis, for such a powerful predator, you have such strong prey instincts," she teased. Mollie's hands moved, with hardly any prompting from Anya, to massage the younger sister's breasts. They had increased in size since early last night, from generous to now absolutely massive. Anya straddled Mollie's upright knee and started to rub herself back and forth as she resumed her story, voicing both sides...
 
"Justin was a little shy at first, so I practically had to push my boobs into his hands to get him working on them. But once he did, it was just as I'd hoped. He was so eager."
 
"'They're so big.' He was stating the obvious, but I didn't mind. It was a great cue for me to brag.
 
"This might be about the biggest they've ever been. They tend to gradually shrink back down after a while... after I get some action. Do you like them?"
 
"... yeah. Normally I'd... prefer a little smaller, but this is... amazing."
 
"Smaller like... Mollie's size?" Anya paused a moment so she could at Mollie's nipples herself, licking and play-biting. Mollie let a little moan escape, causing Anya to grin.
 
"'No, Mollie and I are done,' Justin tried to tell me. 'We just... don't see eye to eye on some things.'"
 
"'Like what?' I asked, knowing full well the answer. Right about then, I started to open up over his knee." And while she was talking, Anya had started again, her pussy opening wide to press down and casually engulf Mollie's kneecap.
 
"Like being digested," Mollie suddenly whispered as she knew Justin must have said. Her voice was still somewhat distant, but she seemed to be coming back to her senses.
 
"'Well, sure, Justin. Maybe you don't notice because you spend so much time inside her, but she really cares about you. If she gurgled you, who's she going to have sex with after that?'" Anya chuckled as she pressed down harder until she finally felt Mollie's foot pop inside. The little sister's pussy had taken in Mollie's left leg from the knee down.
 
"Fuck." Mollie said, half from pleasure and half from frustration. She willingly lifted her other leg up and began to feed her toes into Anya's greedy slit. Anya's hips parted wide to accept her sister's offering, which slid right in.
 
"Justin didn't care, though. 'But you'll do it, won't you? You digest people all the time.'"
 
"'I do. But I'm feeling pretty full right now. After all, I did eat two whole people today...'"
 
"Of course, Justin had gotten hard as a rock again because I'd gotten both of his calves inside of me by then. It helped that he'd been already lubricated by a certain someone." Anya leaned forward to tease at her sister's slit. She let Mollie slip out until only her ankles were still buried in Anya's pinkflesh, so that she could spread Mollie's thighs apart and lick at Mollie's flower. "Last chance," she intoned seductively as she pressed her face into Mollie's pussy. Anya's flexibility was doubly impressive given how her huge breasts were squished up against Mollie's legs.
 
Anya's ministrations were expert enough that Mollie gasped and sucked Anya's whole head into her steaming vagina. "Ooh, I can still taste a little bit of Justin in here," the bustier one mumbled through a wall of flesh. "Now come on, finish me," she added in another uncanny impersonation of Justin's tone and mannerisms.
 
Mollie huffed and squirmed, although Anya's weight on her legs didn't make it easy. Finally she took a deep breath and contracted her vaginal muscles to push Anya back out. "I can't. I just can't. Fucking dammit, Anya, just take me and froth me like you did to Justin."
 
"I had a feeling you might say that." Anya wiped the fluids from Mollie's pussy off her face, and began thrusting her hips forward in earnest. Soon she had passed the previous high-water mark on Mollie's lower thighs and was working her way up to the older girl's nicely rounded hips.
 
"Justin told me, he drawn to you because he knew you had a special pussy and you'd even vored before. I guess you had other things in common, too, 'cause there's plenty of unbirther rumors out there, but still, he was always waiting for the time you'd finish him off. He'd finally given up on waiting, though."
 
"'Please,' he begged me. 'I know you already ate tonight, but please take me and don't let me back out. If I have to wait all night in there while you sleep and digest me slowly, that's fine. Just fucking take me.'"
 
Anya's story was interrupted briefly as she struggled to squeeze over Mollie's (predatorily wide) hip bones. But soon enough, she'd done it, letting the spit dribble out the side of her mouth as she clenched her teeth from the exertion. Her vagina itself was making all kinds of slurping noises of its own.
 
Mollie was reaching her hands down into Anya's distended opening so she could stimulate herself, but Anya reached down to take one hand first. "I've gotta know, though, sis, did you really? Gurgle someone? What did you do that made the rumors start?"
 
Mollie tugged her hand out of Anya's grip and tucked it into the predator's snatch. "I did. It was a long time ago, probably when you were hardly old enough to even know what sex and vore were. It was Justin's best friend, actually. Before Justin and I got close, I knew Nate." Mollie's eyes glazed over a little as she started pleasuring herself even as Anya's labia slurped up past Mollie's arm and the start of her ribcage. "He took me to a party. That was my first time with alcohol. We both got pretty sloppy and went off to a back room somewhere. I don't remember too well, but there must've been someone else there to see it and spread the rumors. But when I woke up later, I had what was left of Nate sloshing around inside me."
 
"Holy shit, sis, I never knew! And here I thought the age gap between us wasn't so big a deal, but you were traumatized all along? No fucking wonder!"
 
"Yeah, damn it all. I mean, Justin and I kinda bonded through knowing Nate, at first. Especially because, you know... what it's like when you've taken someone. But I didn't realize... all that time, Justin must've been so jealous about how I frothed Nate so easily... but I wouldn't do it to him."
 
"Yeah," the younger sister said. She squeezed her thighs up against her prey/sister's shoulders, to comfort her... and also to make it easier to squelch up comfortably past Mollie's chest. Pressing in like that made Mollie's cleavage show, and Anya couldn't help but reach down and massage her sister's nice, hand-size mammaries until it came time to feed them into her cunny.
 
"So you're really gonna digest me, then. Just like you did Justin."
 
Anya grinned. "I've already started." Indeed, the bulge in her belly didn't seem big enough to comprise Mollie's whole body.
 
"No wonder it feels so good," she said, closing her eyes as Anya's labia licked at her neck. "I can just feel my cares... melting away."
 
"I should probably get some Worst Sister Ever award, huh? I ruined your date, stole your boyfriend, sloshed him in my vag, teased you mercilessly without even knowing your real story, and now I'm just gonna fuck you into tit fat, too. What the hell!"
 
"No, it's good. I think I wanted this, something like this, for a long time. I was so envious, you know? Every time you brought someone else home to vore. I just didn't realize I was envying them, not you. Probably because I was trying stupidly to be faithful to Justin, even though we both wanted something different. I fucked it all up, didn't I?"
 
Anya had paused with only her sister's head still waiting to disappear into Anya's slit, but her stomach was making gurgly noises already. "Hey, at least you and Justin get to be together in the end, right? Now hurry up and get in me, you fraud of a predator." Anya had to lean back and spread her thighs apart to pull her sister the rest of the way in, so she couldn't see it, but Mollie was smiling.
 
Anya tossed and turned on the bed as her stretched belly got steadily smoother and flatter. She came again and again from the feeling of Mollie's last moments, massaging her breasts as she felt them grow even more from her pussy's fourth meal in under a day. As Mollie faded away, the feeling of intense gratitude floated up into Anya's mind, leaving her with an exhausted smile. "You're welcome, you two. Both of you." It had been a hell of a weekend.
