Cecilia goes to her old home to shake off her past, the fun way

As much as Cecilia loved her new life and her new mother, she couldn't say that Aphrodite wasn't a mother all the same. She made her do things she didn't want to, specifically go back to her old home and pretend she still had any regard for her original genetic donors, or at least one of them. Her step-father was a no-good, deadbeat lay-about and her mother worked hard enough to almost never be home. Not exactly an ideal household, and certainly not one she wanted to return to after the absolute acceptance and encouragement from her new mother goddess and the perverted virus she could control.

"I'm home," she called reluctantly, closing the door behind her as she looked at her phone. She was disappointed to see she hadn't gotten the text she expected and wondered how long she'd have to wait while she itched at her shirt. Her new body hated the clothes she had to wear and longed to strip them off immediately, but she knew she couldn't. Not yet. And for one specific reason.

"Sup, sis, tits get bigger? Maybe I can check for you," came the grating voice of Bennett, her step-brother from her step-father's previous marriage. He had never neglected the opportunity to shamelessly hit on her, creep on her, and even 'accidently' walked in on her in various states of undress before. The like-aged boy was a pervert, a lecher, and a creep, but maintained a brutal honesty with his desires, something that Cecilia couldn't help but be slightly attracted to. She hated to admit it, but in her darkest, most depraved moments, she considered taking him up on it. Inviting him into her room to help her scratch the unbearable itch of her horniness. Now, she was so glad she hadn't. It would make the next bit so much better.

"Depends, where's your dad?" Cecilia said with her usual annoyance, looking through the fridge for something that peaked her appetite. Other than sex, that is.

"Out, probably at the bar with his friends. All I know is the house is quiet, and that's all I care about."

"Surely that's not all you care about," the redhead cooed, gently thrusting her ass out and up, easily catching his eye. The virus whispered to Cecilia, making seduction second nature and effortless, especially when directed at someone who wanted her as much as her step-brother did.

"What, you finally considering my offer?" he asked cockily, arrogantly ruffling his brown hair.

"I'd say more than considering...but why don't you come upstairs in a few minutes and find out." The Divine princess swayed her way out of the kitchen and up the stairs, intensely aware of Bennett's eyes on her rolling ass. She had always found his gaze irritating and foul before, though given how much she had changed, she shouldn't be surprised at liking it just a little. Of course, she still loathed him, but she could separate desire from attraction.

As soon as she was out of Bennett's sight, she began stripping off her clothes, starting with her cardigan and ribbon. She carelessly left them in the hall, leaving a trail for her step-brother to find that would lead him right to her. Not that he would struggle with that, but it was a bit of fun before the real fun started.

Not that she was going to wait for him. The rest of Cecilia's clothes were easily removed as she laid on her bed, and her full viral divinity came forth. Her already large breasts jumped in size, thighs rippled, her butt gained a little extra bounce, her hair lengthened to its new span. She couldn't stop the moan that came from her, nor her hands as they found her tit and pussy. Her abdomen spasmed at the lightest touch to her sex and she didn't bother to hold in her moans. She writhed under her own touch for what felt like no time at all until she heard the door open and blinked to see Bennett standing there with his mouth hanging open.

"Holy shit," he whispered, completely unprepared for the ultimate erotic sight that greeted him. Cecilia was splayed out in front of him in all her glory and more, and he was going to have her. He had managed to frantically shuck his shirt off and was working on his pants when he heard something from his step-sister other than moans.

"Is this what you want, Bennett? What you've wanted since you met me?" she asked, spreading her labia with her slick fingers. "You want this pussy?"

"Fuck yeah!" he yelled, finally managing his belt and stripping the rest of his clothes off in a single stroke. His dick bobbed, slightly above the human average, but far less than what Cecilia was used to seeing.

"Well, too bad, cause...hahhh...I've got...something....else!" she panted, and Bennett watched with incredulous eyes as something thick, phallic, and throbbing pushed out of his step-sibling's gushing slit. His own dick lost some of its hardness as he watched the enormous shaft just continue to get bigger, until it was more than twice as long as his and unfathomably thicker, not to mention the two balls bigger than fists that popped out to join it.

"You always wanted to fuck me, Bennett, but I think you should have specified how! Now I get to choose instead!" Cecilia said, lust dripping in her voice. "I haven't fucked any boys yet with this thing, so you should be thankful you get to be the first!" She suddenly lunged at him, massive curves and cock bouncing wildly as she grabbed him with strength that far exceeded what she had before. He let out a pathetic, high-pitched squeal when she grabbed him and another, even louder one when she put the head of her thick dick against his asshole. He barely noticed Cecilia putting her colossal tits around his own penis, having to stay focused on holding himself in a half-squat to keep from being reamed.

"Okay, here's how this is gonna go. I'm going to give you the best titjob you've ever dreamed of, just like this. If I get you off, you get to fuck me however you want. But if your legs give out and you get impaled on my fat, throbbing futa-cock before you cum, I get to fuck you however I want. Sound fair?"

"Cecilia, please don't, I'll~ohh SHIT!!" Bennett's pleas were immediately cut off as his futa step-sister started moving her enormous boobs, fully engulfing his dick in their warm, squishy embrace. The intensity of it made his legs shake immediately and he had to strain himself even further to keep them from giving out.

"Shit, does this feel this good to you too? I haven't gotten a titjob yet. My boobs feel incredible though; they're so fucking sensitive. I bet I could cum if you keep this up long enough. Though I'm not sure that's what you want given where my tip is."

The only sound Bennett could make was that of struggle, trying to keep his legs tensed, not think about the dick pressing on his asshole, focus on the frankly incredible feeling on his cock, and work at cumming all at the same time was horrible and utterly taxing. The very small thrusts Cecilia was making weren't helping things. And to make things worse, with every second he endured, the more he thought maybe it wouldn't be so bad to give up. He tried to **** those thoughts down, but was having a hard time doing that and focusing on everything else too.

Fortunately, he didn't have to for long. Unfortunately, and somewhat predictably, it ended in the worst way for him. His overworked thighs couldn't hold him up anymore and he shuddered with despair as his weight was **** onto his step-sister's enormous cock. Despite its thickness, it had no issue forcing his ass open with agonizing slowness.

"Ffffuuuuuccckkkk....shit, your ass is so tight!! How deep do you think I can go?!"

"Pleeeaaaaseeee...." he moaned pathetically, to no effect. Cecilia just kept panting, giving her hips tiny thrusts and squeezing her tits even tighter around his twitching dick. Most delightful of all though was the firm grip Bennett's asshole had on her own cock, a tightness that only seemed to increase the more it slid inside him.

"Ngh, shit NO!" the brown haired man yelped as Cecilia's fuckrod pressed up against his prostate and his balls clenched. Despite his best efforts, he felt cum pumping up his length and spurting into his step-sister's extensive cleavage. He was ashamed to see that, despite how hard he was cumming, not a single drop of his jizz made an appearance from within her cleavage.

He didn't have more than half a second to be disappointed though as Cecilia moaned her own orgasm, the hot jizz on her chest finally setting her off. The knowledge that she was going to cum into another of her long time tormentors made it all the more intense, and she reveled in the yelp and whimper that came out of her step-brother as she filled his rectum with infectious seed. His cock spurted another, much smaller load onto her tits. She watched in supreme satisfaction as Bennett's eyes rolled up and he slumped over and off her, shuddering lightly.

A sudden vibration from her phone on the bed drew her attention and she immediately jumped for it, hoping it was what she had been waiting for. She flicked it open and wasn't disappointed. Before she had left school, she had given and already pent up Jasmin a specific order: go home, infect whatever man she found there, debase herself in front of him however she wanted, and send her a picture. In return, Cecilia would let her cum once. It had taken the slut barely five minutes of futile and unsatisfying sex to agree, and now the redhead was seeing the results.

Jasmin was naked, as expected, on her hands and knees. She must have had a dog judging from the collar around her neck and the large bowl she was licking thick white goop out of. The bowl was filled with it, and a thick strand connected it to Jasmin's partially outstretched tongue. Cecilia didn't need a second guess to figure out what it was, especially given the absolutely massive cock attached to the man kneeling over her. He had a leash in his hand attached to the collar around her neck and her long hair was wrapped around his prick.

Cecilia hadn't through she could get harder, but somehow she managed. The sight of the absolute slut that tortured her on her knees, cum-drunk and drooling, was so utterly arousing. She didn't know who was holding the leash, but she wished it was her. She wished she could savor that silky skin with her own fingers and feel Jasmin's plush tits and ass. She hit the call button on her phone, looking forward to hearing the black-haired girl's moans, while she turned to another, much closer source of moans.

Cecilia's phone rang whole she looked at what had been her step-brother, a little disappointed she had missed Bennett's change from a stuck up, arrogant, perverted asshole into the mewling, lewd futa fuckdoll he had become. She watched him, now her, shudder on the bed, panting with need as she spread her legs, showing Cecilia her much smaller cock, cum-smeared torso, and her asshole-turned-pussy leaking the redhead's own jizz.

"Fuck me more, sis, please, I want more of your cum in me! Fuck my ass-pussy! Let me slam my tight booty down on your huge, jizzy dick!!" she begged, nearly sobbing. Cecilia couldn't tell if it was from helpless desire or in horror at what she was saying, but the Divine futa found she didn't care, especially as her phone connected.

"Mis...tress...." came the pleading sound of Jasmin's voice from the other side.

"Why did it take you so long to answer, slut?" Cecilia demanded immediately, her eyes not leaving her transformed step-sister's lewd pose.

"My dad...was fucking...my ass..."

"What was that, slut? Why don't you try phrasing that differently?"

"MY DADDY IS **** MY WHORE ASSHOLE AND I LOVE IT!!" Jasmin screamed from the other end of the phone, and Cecilia could practically feel her sexual agony. Despite getting what she was sure was a thorough dicking, Jasmin couldn't cum, not without Cecilia's permission.

"Good, I'm glad you can be honest with yourself," the redhead said, listening to the tormented girl whimper and sob with humiliation and need, while she idly rubbed her dick at her mewling step-sister's messy hole. "Now, what did you want to ask?"

"Please...let me cum...I did what you asked...I need it...I feel like I'm going to explode..."

"Well, we wouldn't want that, now would we, Baylee?"

"B-baylee?" Jasmin asked quietly.

"Oh, sorry, I'm talking to this bitch. Say hi, Baylee." Cecilia held her phone up to her step-sister at the same time she shoved her dick into the new girl.

"AAaUuUGhgHGHHmmMNNYYEeaAAnnNNggGH!!!!!" Baylee screamed nonsensically, shaking and spasming in violent orgasm as her small cock shot its pathetic load over her own body. Her new plush flesh jiggled and bounced with every powerful thrust, an absolute treat for Cecilia's eyes.

"Please...." Jasmin moaned over the phone, a new degree of desperation present in her trembling voice.

"Oh, sorry, this cunt is just so good. Did you want something?"

"Please let me cum...please...you promised...you PROMISED!!"

"I did, didn't I? What do you think, Baylee, should I let her...ngh...cum?" Cecilia asked the futa under her at the same time she filled her with fresh cum.

"UUUBB...BLLURGHH! MOORRGGHH!!" Baylee choked out, surprised by the flow of jizz that came up her throat and spilled over her, but loving it nonetheless. Cecilia had made her guts little more than a straight tube, her mouth and single hole between her legs connected to make her a living onahole, something both girls wanted to take further advantage of.

"Sorry, bitch, but I'm a little busy right now fucking my step-sister, so you're going to have to wait. You understand, right? See you at school tomorrow!"

"NOO-" Jasmin's scream of despair was cut off as Cecilia hung up her phone and tossed it aside, before slamming her hands down on either side of a thrashing Baylee. She thrust harder, enlarging her dick with each push of her hips. She couldn't decide which she was looking forward to more: seeing the state Jasmin would be in the next day or watching the head of her cock emerge from Baylee's throat. Luckily, she wouldn't have to choose.
