Black Widow Her Sisters Keeper

Natasha's eyes raked over me as soon as I walked in the room and it was hard not to suppress a certain shudder. Even if she was my sister, it was impossible to ignore how attractive she was, especially in that catsuit of hers, and having her openly appraising my physique set up a frisson. I looked pretty good myself—what, was I not living up to her standards?

"You wanted to see me?" I asked, not bothering to suppress my Russian accent anymore than I usually did. I don't know why Nat still play-acts being American, so I can only hope my Slaviness pisses her off as much as her Yankeeness does me.

"Yeah," she said. "It'll take a bit. You need to use the restroom?"

"

God,

you are such big sister. You know, not everyone wears catsuit. If they need a bathroom break, it only takes ten seconds, not half of day."

"Yeah, yeah," Natasha crossed her arms, but with a fond grin for me. I wondered what the

suka

had planned.

There was a knock at the door. I didn't feel like answering it when it was no doubt whoever Natasha had invited, so I glared at her as she went and opened the door.

It was Kate Bishop. God, she looked good. I still dress like a boy, or at least a Marine, but Kate Bishop knew how to fiddle with all the bra and panties and earrings and eyeliner so she took how good she looked normally and then she looked great. Like a really nice movie on one of those super-TVs that nerds set up.

She had these stretchy pants that I just knew were pulled taut over her ass and a sweet little tanktop that showed off a few of her abs because it wasn't big enough to reach her waist and a baseball cap, which I still liked...

"Good, you're here," Natasha said, virtually pulling her inside. She shut the door behind her. "I'll be blunt, so Yelena can't backtalk me to death. You two need to fuck."

Kate Bishop made the customary noises of confusion and protest I would've expected from her—still cute—while I said a more succinct "

Blyat...

what is wrong with you?"

"It's frustrating the hell out of me," Natasha interrupted. "Yelena, you're such a bottom that it hurts—Bishop, you're obviously crazy about her, you're just too much of a little bitch to give it a go... so top her and get it over with. She's

way

too much of a sub to give you any trouble. Just do it already."

"I am

no

sub," I stressed. "Who killed Dreykov, huh? Me."

"And I'm not a little bitch!" Kate Bishop added.

"You're kinda a little bitch," I admitted. "It's part of your charm."

"See, she thinks you're charming," Natasha said.

"I don't see how this is your business anyway."

"Because I'm your sister and I want you to be happy?" Natasha asked in a tone implying I was retarded for asking, which did seem familial to me. "And you need to get laid. Really."

"'Really.'" I imitated her stupid fake accent. "You get laid."

"Maybe I should." She looked Kate Bishop over. With the way we stood, Kate Bishop and I were facing each other, but Natasha could look behind her and she did now, taking in the swell of her hips like a hand running up her legs. Even I just about felt it. "She probably couldn't handle me at first—I'd have to do all the real work—how about strapping something on and letting me ride it, Bishop? I'd love to look down at that pretty face, seeing how you like being inside me—"

Kate Bishop looked utterly lost. I squeaked out a "Hey!" like a pipe had ruptured.

"She is—don't you dare—"

Natasha looked at me smugly. "You're right. Let's give Bishop a moment to cool off. You bend over the couch there."

"Why in fuck should I—"

"

Now, cunt!"

The warm flush of obedience filled me when I did as I was told, bending over before my thoughts had a chance to countermand my instinct to simply follow orders. And before I could think better of it, I felt Natasha patting my ass like it was a dog's head.

"See how easy she is to dominate? Now, you've got to admit, that is one good-looking ass. One

fuckable

ass. Isn't it, Bishop?"

Kate Bishop sounded like a ghost when she whispered "Yes."

"You must want to fuck it, if you think it's such a fuckable ass. Don't you?"

"Uh-huh," Kate Bishop moaned distantly, and I could tell from her voice that she was too busy thinking about it, picturing it in her mind, to much care what Natasha was saying.

"Then you're going to have to lick it. Lick her dyke ass." I felt Natasha dragging my pants down my ass, and the little relief of my... well-sized ass not having to fit inside a tight pair of jeans anymore. "Get that hole nice and wet so your lezbo cock slides right in. You want it to go in easy, don't you? Not hurt my sister? Because as long as you lubricate it first, she'll enjoy it. How can any woman with an ass like that not love getting it fucked? And if you do a good job, she'll let you fuck her ass again and again and again. Now won't that be fun?"

"I—I won't—" I retorted haltingly.

"Shut up, sis. No one's talking to you. In fact, I have something much better for you to do with that mouth."

And a cock dropped in front of me. A full ten inches of dildo, black and smooth, expensive-looking and luxurious, attached to a leather harness that I knew a woman could wear to give herself a prick.

"That's phase two of this little operation," Natasha announced smugly. "With Bishop getting your ass all lubed up, we can't forget about the dick. Can't have that going in dry. And since your mistress is doing all the work of rimming you, why don't you make it easy on her and spit-shine that cock?"

"You must be joking," I responded, too stunned to be lost in the shuddering case of nerves I would otherwise have. Natasha had always been audacious, but I'd never expected that boldness to be turned on my sex life. I started to get up. "Let's go, Kate Bishop, and see if maybe whoever is selling my sister her drugs will let us—"

I didn't get any further, in speech or in motion. All of a sudden, I felt Kate Bishop's tongue moving between my buttocks. My body trembled—my senses were totally overwhelmed by the caress.

I moaned and went cross-eyed, staring glazedly at the dildo Natasha had dropped in front of me... only able to think that this meant soon it would be going into my asshole, that my anus was being prepared for that full, lengthy sex toy I could see in front of me.

Natasha grabbed it at the base and aimed the tip at my lips. In my present state, I couldn't resist when she forced it forward, and it went into my mouth. I barely noticed. I was feeling Kate Bishop's tongue moving sensuously along my valley, slowly and wetly across the burning skin that covered my tailbone and then back down, in a descent of kisses, along an asscheek that felt positively stuffed with nerves and feelings, before she ran her tongue back up my cleft and over the puckered tightness of my anus.

I nearly passed out, explosions of electricity replacing what had once only been excited tingles. I tightened reflexively, but Kate Bishop licked at my sphincter so frenziedly that I couldn't imagine keeping it closed. I began to imagine it penetrating into me, that wet-flame feeling going into the tender nerves that lined my channel. And even that would be nothing next to being impaled by an actual phallus.

More than a phallus—those were soft, spongy flesh at the end of the day. My lips could very well feel what indefatiguable solidness would end up used on my virgin hole.

"Does it taste good, sister? Or maybe it's missing something—the flavor of having been in your ass, maybe?"

Without realizing it, I had inched my lips down the length of the dildo. When next Kate Bishop tickled my anus, my whole body seized up, including my mouth. I bit down on the cock, but of course, I could do nothing but leave the most superficial of marks on its hardness. My asshole stood no chance against this preternatural stiffness.

My heart began to pound. I wasn't worried, exactly... not about being violated by that unnatural thing... but there was a rush to the thought of how it would feel. Not only being fucked where I was not designed to be fucked, but by something too harsh and hard for the human body to ever have been meant to take.

I was afraid to experience it. I didn't know, couldn't know, if I was ready for such extremes of sensation.

But how could I back down? Stop sucking the strap-on? Leave it dry, to go into me dry? At least if I lubricated it properly, it would go in sweetly, feeling good...

I relaxed my jaw, prying my teeth out of the silicone, and started up the pumping of a good blowjob on the cock. Not that it mattered, but that was how I knew to use my mouth on such a thing. Natasha cooed approvingly.

"Bishop's a very lucky girl. Next time you do that, do it while she's wearing the thing. I know I'd love to see a pretty gal like you going down on my fucker... even if I don't have the receipt for it."

I 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."

I shoved my ass back and quivered to feel it going into my hole as best it could. I felt my sphincter expanding, did my best to relax and let it in further. Lubricant chilled my walls as it was smeared off the dildo and into my flesh, it was comforting to feel the slickness of it. Maybe it would let the strap-on into my ass without totally devastating me. I was more open than ever, taking more than I'd ever imagined my sex life would involve.

I shut my eyes tight against the pain flashing through my stretched tissue, but the pain was overtaken by a flaring bloom of delight. Kate Bishop's dildo was going even deeper. I was actually taking it into my ass, my bowels, everywhere in my body that wasn't meant to accommodate being infiltrated this way.

It was only a quarter of an inch, but it felt like my asshole was no longer my own. And I was only beginning to open, only starting to take what was going into me. I felt ecstasy flowing through the continuous pain of impalement like water through a dam; it was like coming without coming. I pushed back and gritted my teeth on the pain I was suffering to get off.

Kate Bishop then took her dildo by the base and pushed it in all directions against my walls. I let out a hiss as I felt the dildo prod one set of nerves and then another. I screamed as it worked deeper in with the rotation.

Shit. I was being fucked. I was actually being fucked in my ass, a dildo piercing into me, Kate Bishop enjoying being able to do this to me. She had to be enjoying it... that was the only way she could inflict this pain. Did she know how much I was enjoying it too? Or was she only taking Natasha's word for it? I didn't feel like I had nearly the reserve not to show what I was feeling, no matter how embarrassing it was to get off on this debasement.

Kate Bishop panted harshly. Her breath came in short bursts, close to speech. On each exhale she seemed to mumble either my name or some curse.

I could've laughed. She sounded embarrassed... ashamed of what she was doing to me, or maybe how she felt about it. Not that I had room to talk with the delirious excitement I felt charging out of my filling passage.
