It was a strange sensation to awake (if what you'd been doing could even be classified as sleeping) in your 8 inch plastic form. Wanting to yawn and stretch out your arms and legs, before of course remembering that you didn't have any. You were currently a dildo. An exact replica of your mother's to be precise. A punishment for tricking your sister with the medallion the day before. Which she had assumed would be both amusing for her and humiliating for you, but had turned out to be something else entirely. Due to a huge misunderstanding as to which dildo was real and which was you, and your mom's sudden and unexpected bout of horniness. Having spent the previous night been used to pleasure her. The memory of which suddenly came rushing back. The warm wetness and sucking sensation as she took him into her mouth. The sight of her fully flowered vaginal lips as she had led you towards them. The moist pink tunnel between which you were soon plunged inside. Back into your own birthplace. Being tightly squeezed and massaged by the slick, velvety soft walls as you were rammed in and out of, in and out. Smelling and tasting the thick juices that built up inside. Giving your mom multiple explosive orgasms. Which was just about the most fucked up thing any son could say about their mother. But then... she had been none the wiser. Assuming that you were safely stashed away inside her underwear drawer while all this was going on. Imagining that she would be mortified if she too knew the truth. That she'd mistakenly used you to fuck herself.
(Oh God... Please don't let her find out) You silently whimpered, feeling shameful enough as it was. Not only at having been involved in something so incestuous and wrong, but also because of how amazing it had felt as it was happening. Perhaps not having the normal senses that you would as a human, but that didn't mean you couldn't feel what was going on. Or the fact that being buried inside a pussy didn't cause a mental arousal the likes of which was impossible to describe. Mother's or not. It being so damn kinky.
As was where you were currently positioned. Having no eyes, but the medallion's magic (as with your other senses) still allowed you to see. Being flanked by two massive pink mounds of flesh that had pancaked somewhat off the sides of her body. Laying between her breasts. Her very large breasts. A thick brownish nipple visible peeking up over the horizon of the left one. Looking so big, juicy and succulent indeed. Which you never imagined in a million years you'd be thinking about your own mother. Having, on that one occasion that you'd shifted into her body to prank your sister, avoided any sort of examination. Thinking it gross. Not now though. Now you were positively blown away by it. Which of course only added to your current feelings of guilt and shame.
It was at this point, as your eyes were scanning the impossibly large slopes of your mother's creamy flesh, that she began to stir. Feeling her body move beneath you, which in turn caused you to roll. Falling from off her chest as she sat up yawned and onto the soft, bouncy comforter beneath. Looking up at her as she ran her fingers through her soft blonde hair. Her big dangling breasts appearing even more spectacular from this angle. Which you knew was weird. (They're Mom's!)
"Whoopsie. Looks like I forgot to clean you up last night," she mumbled with a smile as she finally noticed you there. Her fingers wrapping themselves around your lower half as she picked you up. Indeed still being slightly sticky from her now dried on juices. "Guess I'd better do that before I check and see how Liam is doing."
Being carried over to the dresser then and placed on top while she fetched her silky blue robe and put it on. Finally covering her naked form. Still having no clue whatsoever that you were already with her.
...That was until she grabbed a hold of you again and ventured out into the hallway, towards the bathroom. Meeting your sister who was just on her way out.
"Well, well, well... Looks who's up later than I am," Belle chuckled smugly. Looking rather disheveled and hungover from her night out with her boyfriend. Quickly spotting you lodged firmly in your mother's hand. Which caused her grin to widen even more. "Oh... So that's why, huh? You were having some fun of your own."
Your mom's response to which was one of embarrassment. Appearing rather flustered at being caught. "I wasn't... I was just... uhm..."
"That's okay, Mom. Don't sweat it," she told her, being rather laid back. "We all like to have fun in our own way. Though I bet you're glad I remembered to put that thing back before I went to bed? Otherwise... Well, things might have gotten a little awkward."
This part causing your mother to suddenly pause and for you to think to yourself, Oh-oh. Fearing that the truth was indeed about to come out.
"Wait... What do you mean? Last night you were trying to switch them..." Your mom said. "...And I... I caught you doing it." The cogs now turning in her head.
"Yeah. I was putting that one back in your drawer and I was going to take Liam out before you ended up using him instead."
This being it. Your sister having just dropped the bombshell. Which caused your heart (metaphorically speaking) to drop. Pretty sure your mother's did the same also as she suddenly realized what she'd done. Not being able to see her face from your current position, but you imagined it looked utterly mortified. Her voice now being little more than a squeak. "...Oh."
Not that your sister appeared to notice this. Presumably being too preoccupied with her hangover. Apologizing instead, "And sorry for taking it without asking. I just... Well I got a little horny myself and there was no way I was going to use Liam. That'd just be... TOO gross!"
"Uhm... Yuh-yeah," your mother muttered then. "Yeah, I guess it would be."
While at the same time you were left thinking, (Just kill me now.) Having been used in this way being distressing enough, but actually having to face her now once she turned you back was going to be an absolute nightmare. Neither of you would be able to look each other in the face again. A fact that she had to be all too aware of.
"Anyway, how's my dumb brother doing?" Belle continued then. "Still enjoying life as a plastic sex toy?"
"I, uh... I'm not sure..." Came your mother's rather feeble answer. Trying her best to retain her composure and failing miserably. "I was just going to check on him after I... I gave this... this, uh, one a wash." Especially after she looked down towards you. Turning your plastic body in her hand as she did. Appearing just as shocked and as embarrassed as you'd imagined. Almost immediately pulling her eyes away.
"Heh. Cool. Well send him my best. I was just grabbing some aspirin. Think I might head back to bed for a while."
"Oh-okay."
And with that your sister turned and headed down the hallway. Leaving just you and your mom alone. Fully aware of who it was she was now holding within her grasp, as well as what she'd done with you last night. Letting out an audible little gasp of "Oh God", as she hurried on into the bathroom and closed the door behind her. Dropping you into the sink.
"Liam, I'm... I'm... I'm so sorry," she immediately blurted as you rolled back and forth in the sink. "I... I didn't know. I honestly didn't know that it was... That you were... Oh my God. This is a nightmare! Can you... Can you ever forgive me?"
Well of course you could. It wasn't her fault. She hadn't known. If it was anyone's fault it was Belle's. It was her idea to turn you into a replica of your mom's dildo in the first place. The idea behind which was presumably to create a fear within you that this situation might actually happen. Even if she hadn't expected that it actually would.
"I know that saying sorry doesn't make it right, and that the things I did to you... The places I put you... It... It..." Her voice faltering again as she conjured up these memories. Which made you do the same. Having been wedged inside the very tunnel that you'd entered the world out of. Over and over again. Not to mention that she'd rammed you down her throat to suck off the juices. Acting very much like a porn star rather than the parent you knew.
This realization causing her to suddenly grab you and run you beneath the faucet. As if she was trying to wash away her sins along with her vaginal secretions. Apologizing again and again as she did.
"I'm such a bad mother. Such a horrible mother," she then began to murmur, once you'd been cleaned and washed and now sat atop the sink. Watching as she backed herself up against the toilet, and slumped herself down. Covering her face with her hands as she did.
(You're not, Mom,) you wanted to tell her. (You're not a bad mother.) Which of course you couldn't. (And it's not like I didn't get any enjoyment out of it myself. I got to fuck a pussy after all.) Repeatedly.
Being left instead to just lay there while she stayed like this for a full five minutes. Clearly processing everything that had happened. Until finally she moved her hands again and looked back at you. Uttering softly…
