Pt. 09:
"Hold still," the squirming Katy was ordered, my wife trying to fit the butt-plug she'd bought into the coed's rectum. "If you don't stop resisting me, it's only going to hurt even worse when I finally get it in."
"Whatever," I gave up after trying to talk her out of her eccentricity. "Fuck it, I don't care, but you're not leaving the house with her, especially to do... yeah."
"Ugh, the only reason I'm fighting this rascal is to do yeah, so hold her legs or be quiet."
"But I was only kidding, Miranda!" the girl pleaded. "I promise I'll behave, and I liked tonguing your ass, so just stop. You know I'm sensitive there."
"Everyone's sensitive there, don't be foolish. That's why it feels good, but you're never going to learn that unless you let me—aha! " With a plop, the toy was stuck into my sibling's anus, causing her eyes to widen, her jaw to drop, and her toes to curl. "I got it... See, isn't it easier when you give in?"
"Oh... god..." she gasped, where she lay upon her back, unmoving. "It's too big, Miranda, I wasn't ready," and similar phrases were repeated.
"Shush," my spouse cradled the panicking thing's head and stroked her face. "Be calm, relax, and ride the sensation out until you adjust. Then, when you're adjusted, you'll learn to like it. That's it, ease the tension in your body and let it happen."
"...I can feel my heart beating in my ass," the blonde confessed, "and then my insides are trying to pull it up deeper instead of out."
"You'll get used to it. The plug will keep you stretched until the elasticity in your muscles wear enough for it to become pleasurable. Don't worry, though, you'll still be tight, but it'll become more comfortable for you, where it won't hurt as much, even when you get fucked."
"Maybe it's not so bad when I don't try to move..."
Reaching for Katy's cunny, that she may stroke at her clit, the brunette said, "The more aroused you get, the better it'll feel—"
"No, stop!" she pushed her hand away. "...When you touch it, I clench."
"Relax, then, and why don't you try it yourself?"
There was a pause, and then the college student asked, "Do you promise it'll feel better?"
"This is how I learned, so it's how I'm teaching you. Isn't that good enough? It worked for me, and I know it'll work on you, too."
"...But my thoughts are all fucked up, and I don't want to masturbate thinking sick, nasty things," despite the guarantee, she remained hesitant.
"Aw, cup-Kate, it's okay. It's alright if you have sick thoughts. Everyone has sick thoughts, and they feel so, so good when you revel in their filthiness. Maybe if you tell me what they are, I can help you better deal with them."
"I don't know, Miranda, I'm embarrassed."
"Embarrassment is only a form of shyness. Once you admit and accept your compulsions, once you openly indulge them, then they become commonplace and you're not embarrassed anymore."
"...I'm thinking about vaginas."
"Wait, is that it? That's all?" my wife was surprised, though only because of the lack of shock value in the girl's sexuality. "You made it sound like you were thinking about being..." (Censored.) "Or about being tied up in a public bathroom and forced to fuck everyone who enters until you're an annihilated, cum dripping mess. Thinking about pussy is... well, so tame."
"God-fucking-damn," I swore. "That's not what you think about, is it?"
"No, I think about..." and, due to the horrific nature of what she detailed, I will exclude what she proceeded to tell us.
"What the fuck, Miranda?" I suddenly didn't know the person I married. "Why would that be what you get off on?"
Again, the conversation has been censored. She, however, initiated a long and descriptive story about (censored), touching herself as she told it, and... Imagine what it was about, or don't, because it's too obvious and you should already know where this is going.
"...And, when I understood what happened, I thanked her," was my beloved's conclusion to her terrible tale.
(Censored.)
"I don't care," the brunette shrugged. "It felt good, and I doubt I'd have otherwise discovered the great world of bisexuality if she hadn't have done it. And it only happened once anyway, even though I begged her to do it again."
"You begged..." my words trailed off along with my ability to focus on the subject matter. Taking a deep breath, I said, "Okay, I'm done talking about this. Maybe it would've been better if you never mentioned it." (Censored.)
"You're one to talk, aren't you?" she retaliated. "You know what I think? I think you're just jealous that you didn't have an older sister. You like being taken advantage of so much, so you're pissed that you didn't have anyone to do it to you. That's probably why you like me so much, too, because I like to make you—"
"Okay, okay, whatever, alright?" the woman had to be stopped. "You win, just... no, okay?"
"Wait, what does he like for you to do?" the curious Kate had to interrogate.
"We roleplay sometimes," I hoped confessing that would be enough.
"But... what kind of roleplaying is it?"
"I'm going to tell her," my wife threatened.
"Whatever, fine, but it's not like you weren't the one to get me into it. Don't pretend I'm the sick one when you literally just got done telling us the worst thing conceivable."
"His fantasy is that he doesn't want me to jerk him off, but I do it forcibly anyway, and then I make him cum while telling him all my nasty thoughts."
"...Isn't that what you do to me?" my sister inquired. "I mean, that's the exact same thing we do all the time."
"No, this is different," she clarified. "This is more like roleplay molestation, where I pick a topic he pretends not to enjoy, and I force him to cum to it. Like, 'Oh no, Miranda, please don't make me cum thinking about my mother,' but then it happens anyway."
"That's a goddamn lie," I defended myself. "I told you no for real and you kept going. And it's not usually that fucked up. Usually, we just pretend that I'm afraid to admit that I lust after her and then she makes me confess. Like... imagine if your crush came onto you so fast that you refused, but they kept going, so, even though you wanted it, the answer was still no... kind of."
"I don't know," my sibling stared at me, uncertain. "If someone made me think of Mom during sex, I wouldn't just... give in, which is what you did. Whether or not you enjoyed it is irrelevant when you blatantly let it happen either way."
"You keep telling yourself that, cup-Kate" the brunette snickered.
"Hey, what's that supposed to mean?"
"If I frigged you, like I did him, while sexualizing your mother, you wouldn't resist, you'd cum...!"
"No I wouldn't, because that's really messed up!" the blonde protested.
"Hah, how much you want to bet, huh? I have your family photo album and I know the exact page to flip to for the perfect masturbation material. Yeah, Mommy's fat fucking camel toe. You're probably already wet from me telling you about it."
"Miranda, no," my sister was more assertive than usual. "I'll humor your tamer fantasies, but it's my mom... That's too far, even for you."
Except that it wasn't too far for her at all, especially because I knew that to be the only reason for everything that'd been going on in our lives, since none of this would have ever happened if she hadn't have fetishized our mother. Perhaps it didn't register for Kate, or at least it hadn't until our personal copy of the album was retrieved. Promptly after being laid in front of the half-naked blood relative lying on my bed, the promised picture was turned to, and the coed was shown what I'd fatefully been myself.
Grimacing, Katy declared, "This isn't right, Miranda. I didn't need for you to show me this, especially not now. You've totally killed the mood."
"But only because you're resisting it. What, you don't think Gaby's pretty?"
"You're just trying to trick me, but that's not what I said at all... My mother happens to be a beautiful woman, who I am proud to take after."
"Mm, especially the plump puss," the deviant debauchee purred. "Look, I think I can see a resemblance," the photograph was held by the girl's crotch, comparing the imprint of our mom's vulva to the revealed one belonging to my sibling.
"I, uh..." the coed froze when she realized it was, to her dismay, absolutely true. "That's..."
"What, hot? Yeah, it is," she was antagonized further. "Just imagine what it'd be like if your cunt was grinding against hers. They'd be like two swollen peaches squelching and pussy lip smacking... Ah, god, it's delicious."
"No!" Kate blushed. "I was going to say that it's something I didn't want to ever know about. Miranda, please... Okay, I admit that I'm probably bisexual. Girls are cute, vaginas are attractive, and maybe I get off on you confusing my sexuality, but this is fucking different, okay? I'm—hey, what do you think you're doing?" she shouted when the woman started to suddenly and furiously pleasure her clitoris. Putting her thighs together, writhing, trying to shake her off, my sister said, "You can't, I won't let you! Stop...!"
"What's that, baby-Kate, you won't let me stop? There's nothing to worry about, then, because I hadn't planned on it. In fact," her movements sped up, until it looked as though it probably hurt, "there, I'm going even faster."
