Her Sister's Keeper 2
🕑 Added 2024-07-08 19:00:04 +0000 UTCI felt my body tensing, trying to prepare itself for the shattering pleasure behind me even as it was already working at my nerves.
Kate Bishop’s tongue slid down my ass until I felt it at my sex, moving from side to side, parting my lips with slashes of her tongue that tugged me open before the lick was over and my folds shifted back into place.
I was growing more and more exposed, my labia vividly open, my insides tingling with the desire for more. She moved her tongue slowly, teasingly, not quite touching my open slit but brushing against it almost on accident. Pushing against me experimentally, but more and more. Going inch by inch now into my burning center.
I ground my ass back against her face, feeling her nose pressing into my wet valley. I moved my body to hers like I was giving myself to a cock, not a tongue licking at me.
Wet fire burnt its way through my legs as Kate Bishop pushed her tongue into my sphincter. I moaned involuntarily and desperately worked my mouth at the strap-on cock, trying to block out the feel of her wiggling tongue, because if I let myself experience it fully, I would come embarrassingly quick.
But there was no putting a stop to it. I kept feeling it, attacking the tight walls of my anal passage with hot, wet flicks. Kate Bishop thrust her tongue into me and dragged it back out, giving me a lust I’d never felt before—an awareness of the hungry nerves inside my ass that demanded to be serviced.
I was racked with shuddering waves of desire. I’d never known how much this hole inside me craved being filled. My pussy was sopping wet; it quaked every time I heard Kate Bishop’s tongue working against my anus, wetting me and loosening me until I felt like I was gaping open… though I knew that even then, I surely wasn’t relaxed enough to accept this huge dildo into that space.
“That’s enough,” Natasha said. “You’ll spoil her. No more orgasms until she’s taken you up her ass like a good girl. She has to learn to serve you, to worship you. You’re her mistress and the only way she can show her appreciation is by taking every inch of cock you have to feed her. You wouldn’t do that for just anyone, would you Yelena? You’re not that much of a slut. But you’ll do it for her, because that’s how much you love your mistress. Don’t you want to show her just how much cock you’ll eat for her? That big dick is just waiting to help you prove your love.”
Kate Bishop pulled her mouth from between my buttocks. I almost sobbed in disappointment. I felt her stroke my buttocks, a tender caress, and knew what was coming next. It was almost apologetic, the way she touched me, knowing the foreplay was about to end and my days of being an anal whore were about to start.
I was aghast at the thought that I was no longer her friend, no longer the sexy cool badass who left her speechless with admiration and lust. But on the other hand, I couldn’t wait to find out what was next… how much further I could go into submission and how good it would feel when it wasn’t just her tongue stimulating me, but an honest-to-God cock.
I ground my ass into Kate Bishop, reaching back to grasp her hips and pull them against me. Suddenly, she shoved me down so hard that my breasts squished under me. She ripped the dildo away from me… drool ran over my chin when the suction abruptly ended… and I heard buckles being tightened as she put it on behind me.
“Damn, you look good in that, Bishop,” Natasha cooed. “My sister is such a lucky girl.” I started to turn my head to see, but Natasha grasped me by the back of the neck and wouldn’t let me move. “You can see it after she’s pulled it out of your bowels, Yelena. Right now, you haven’t even earned looking at your mistress. You’re a very willful sub and you don’t know anything about being a good enough girl to get ass-fucked like you clearly want to be. Reach back, bitch. Open up your ass. Show Bishop how that virgin hole looks before she’s ruined it for anything that isn’t being her cock holster.”
I had no choice. I reached back and held my buttocks apart—I could only imagine how my asshole appeared. It felt vividly alive, completely sensitized from Kate Bishop licking it into screaming wakefulness. I heard my mistress breathe out in a gust. She must’ve approved of how it looked. It must’ve seemed like a target, just waiting, begging for the completion that only her strap-on could provide.
“Awesome,” Natasha said, and I heard the snap of the photo app on her phone. “I’m going to title this one ‘normal girl asshole,’ because after tonight, you’re only going to have an ass-slut hole. A big, gaping crater that only feels right when it’s being filled with cock. The only way you’ll be able to stand going without being sodomized for a single minute is wearing a buttplug. You’re lucky your mistress will let you, if only because she doesn’t want to take the time to prep you anytime she decides she wants your hole—”
“Hey, who’s fucking her, you or me?” Kate Bishop asked.
“What?” Natasha said, and the word sounded very different in her smoky-whiskey voice.
“I want to savor fucking her—God knows you’ve sold me on it enough—but I can’t focus if you’re going to go on about what a whore she is the whole time. Either you fuck her, and talk about her asshole all you want, or shut up and let me do it.”
I could hear the only slightly condescending smile in Natasha’s voice. “Alright, Bishop. She’s all yours. Just make sure you don’t leave her able to sit right. That hole of hers—”
“I know,” Kate Bishop interrupted. “I should fuck it like it’s mine. Well, it is mine, and I’m going to fuck it right now.”
I groaned aloud before Kate Bishop could continue what she was saying. God, I was so hot. I felt her bend over me and nibble on my neck, then kiss my cheek, even slide her tongue into my ear.
“Sorry, your sister’s kinda bossy,” she whispered to me.
“You have no idea,” I whispered back.
“You wanna… y’know… stop?”
“Don’t you fucking dare—shit—call yourself my mistress—how can you look at my big ass and go without screwing it?”
“Fine… God, your fucking family, babe,” Kate Bishop groaned, and pulled back enough to bring her strap-on up and into my crack.
She moved it along, letting me feel the warm saliva that I had given to every inch of it, until she paused at my anus, pushing ever so gently against my puckered sphincter. Suddenly it didn’t feel like it was supposed to keep her out. It felt like it was sucking her in.
“Oh, shit, Kate Bishop, I had no idea you could do this to me!”
Kate Bishop smiled and pressed a little harder on my barely resisting asshole. I knew I couldn’t keep her out. She just wasn’t giving it to me hard enough to get in, and I was rapidly becoming livid.
“You didn’t know this ass belongs to me,” the archer grinned.
“It does, so make it yours already!” I said, pushing my hips back to meet that tentatively probing invader.
I reached behind me and grasped the strap-on in my hand. I stroked it a few times, coating both the tip and my fingers with the saliva I’d left on it. I brought the head to my anus and started describing small, lazy circles around my entrance.
My eyes shut. I simply enjoyed the first faint stirrings of sensation, that first little gasp of penetration. The same as it had been with Kate Bishop’s tongue but already so much stronger.
To just feel the heft of the dildo in my hand was extraordinary. To feel it at the entrance to my ass, flooding me with the pleasurable implications long before it entered me physically, was absolute heaven.
For her part, Kate Bishop simply stood there, breathing hard as she watched me rub and service her big fake cock. “You really are a slut,” she said breathlessly. “God, how long have you been fantasizing about this? Have you even thought about it? Or is this the first time it’s ever occurred to you and you’re such a, such a dirty bitch that you’re this turned on by it?”
“Does it matter?” I demanded, no longer making circles with the strap-on.
Now I leaned back, holding the dildo steady so that I pressed myself right into it. My teeth chattered as I thought of how it would feel to have that massive prick sawing in and out of my anus. God, I needed it. I could’ve gone my whole life, not knowing the fuck-loving skank that I really was, but I couldn’t be sorry that I’d found out. I could already tell I’d come like never before with Kate Bishop domming me, if she’d just get out of her own head and see how much I had to have it.
Thankfully, Natasha was well aware of this.
“Tell her to fuck herself,” the redhead snapped. “Fuck herself on your big dick. She hasn’t earned being your cock holster yet. First, she has to swallow that prick—no matter how much it hurts, don’t let her stop. If she can’t act like your ass-fuck whore, she doesn’t get to be one.”
