Disclaimer: I do not own Marvel Cinematic Universe or anything else you may recognize

This is an add-on to my Cap harem fic, and I got the idea from the 'Black Widow' movie. Didn't like the movie much but at least it gave me some fun ideas.

So here are 2 more chapters, but that's it for now. Basically, now if I get any ideas based on new women who enter the MCU, I shall update this fic, and till then it shall be marked as complete.

Have some fun now with more debauchery.

Chapter 41- Wedding gift for Natasha

Steve and Natasha lay naked against each other, having just finished having sex once more, this time right on their wedding night, and Natasha was very pleased again. Plus, it was one of the rare times she did not take Steve's cock (or any woman's strap-on) in her ass during sex.

But she knew she'd be made to do so again, and of course she loved doing that, getting on all fours and offering her ass to a superior man like Steve Rogers aka Captain America, who had shown her that she was really just a submissive anal slut who had tricked herself into thinking she was a Super Top, and she also offered her ass to superior women like Deputy Director Maria Hill, and Lady Sif the Asgardian Goddess of War. But at day's end, her ass, all of her holes, and her whole body truly belonged to her husband Steve Rogers.

The other women in his harem simply borrowed her for use, but she did not belong to them.

However, there was some stuff even Natasha wanted. While she had accepted her life as a sub, she did miss her glorious Super Top days, and the only time she had reclaimed something like that recently was when Steve had allowed her to double penetrate Carol Danvers' asshole alongside him.

But she wanted more than just that, sometimes even she needed to be in power, and now that she had married Steve, she had the perfect opportunity.

"Steve?"

"Yeah?" Steve turned to her with a smile on his face, wondering why she was calling out to him.

"So, we're married now", Natasha said, showing the ring on her finger.

"Yeah we are", Steve nodded, knowing she wanted to bring up something. "So, what do you want from me?"

"Well, since we're married now, I want a wedding gift from you", Natasha finally said.

"Sure", Steve sat up, and so did Natasha, looking at each other. "Whatever you want, Nat, I will give it to you as soon as I can."

And yes, if she wanted to fuck him in the ass for once as her wedding gift, he would allow her to have that too as a wedding gift, because she was his loving wife, and he was her loving husband.

"All right then", Natasha said, and then told him just what she wanted as a wedding gift.

Okay, so she didn't want to fuck his ass or anything, well, he would have given her that if she did want it, but what she wanted from him, he could very easily give her that as well, it wouldn't be any hassle.

"All right then", Steve told her. "Tomorrow morning, you get your wedding gift."

"Thank you", Natasha smiled as they shared a kiss and then lay back down.

Next morning

Steve and Natasha came down after having had a shower, with Maria turning the channels, Bobbi and Sharon cooking, and Sif doing some sword fighting techniques in a corner.

"Good morning", Steve and Natasha said at the same time.

"Good morning", the other four women said back in greeting to them at the same time as well.

"So, Nat, how was the wedding night?" Maria asked Natasha with a smirk.

"Even better than what I had wanted", Natasha shrugged.

"I am happy for the two of you, you are both honorable people, and you have earned your happiness", Sif said genuinely as she put her sword down.

"Thank you", Steve said with a nod.

"Well, we're all gonna have to go to work in a bit", Sharon said. "So better finish up fast."

"I think we can take it slow", Steve shrugged, confusing the others. "Not too slow, just a little slow."

"What are you talking about?" Maria asked.

"Bobbi!" Steve called out.

"Yes Captain?" Bobbi turned to him, wondering what he wanted, though she had an idea about it.

"Take off all your clothes right now, slowly and seductively", Steve immediately told her.

Bobbi didn't even protest, considering just how much of a submissive whore she was, and putting her hands on the hem of her blue shirt, pulled it up, exposing her well-toned abdomen with all her abs, and then she threw her shirt off.

She then unzipped her pants, and turning around, took them off while bending over a little, giving a nice view of her blue panties-covered ass to Steve and Natasha.

Maria, Sif and Sharon too stopped what they were doing to take a look at the hot stuff going on in front of them, since it looked like Steve was going to fuck Bobbi once more, and she was going to take it all like the bitch she was.

Bobbi then unstrapped her bra and threw it off, letting her big tits jiggle out, arousing the rest of them.

Then finally turning around, she bent over again and pulled her panties down, exposing her ass once more, and the others just wanted to touch it, but knew they could only do what Steve said.

She hadn't been fucked in the ass for a while so her asshole wasn't gaping currently.

Bobbi then wiggled her ass. "Master Steve, do whatever you want to me."

"Yeah, about that", Steve said, as all listened in anticipation, and then Steve finally said what he intended. "Bobbi, today you belong to Natasha."

"What?" Bobbi asked in surprise, standing up, fully naked, and the other three were a bit surprised too.

"Like I said, today, you belong to Natasha, do whatever Natasha tells you, and show her the same respect that you show me, and you will be punished if you don't", Steve immediately said in a commanding tone, and the implications of not following were clear.

"Steve is my husband now, and so he was willing to give me whatever wedding gift I wanted", Natasha finally revealed to Bobbi. "And I asked him to let me have you have as my bitch for one full day."

Natasha smirked cruelly as Bobbi gulped, knowing just why she had been picked by Natasha. Natasha and Bobbi had a lot of sex fights, and they all ended with Bobbi winning due to being a better tank, and so she fucked Natasha's ass and spanked her as much as she wanted, lording this all over her.

Now Natasha had the perfect opportunity to pay her back, and wasn't going to waste it.

Bobbi knew if she didn't follow, Steve would punish her. She had no choice. Natasha wasn't the Black Widow for nothing. She had outplayed her at last.

"All right", Bobbi said, her head lowered.

"All right what?" Natasha asked with a raised eyebrow, and Bobbi realized what she was supposed to say.

"All right Mistress Natasha", Bobbi corrected herself apologetically, and Natasha smirked.

"Well then, do what you want Nat, we shall watch", Steve said with a smirk.

"Yes, this is going to be a sight to witness", Sif agreed with a nod.

"Yeah, let's see how glorious Black Widow was as a Super Top", Maria added.

"And who better to be her sub than the Mockingbird, god this is hot", Sharon said.

Natasha opened her nightgown, and let it drop, revealing herself to be completely nude, and her perfect body showed was proof enough of why so many people wanted to get into bed with her.

But her body was reserved for use by her Master Steve and many mistresses.

"Get on your knees, bitch", Natasha ordered immediately once she was naked, and Bobbi did, not looking up, though Natasha could see her pussy wet due to what was going to happen. This was going to be easy.

She walked up to Bobbi and said. "Now, lick my pussy, please your Mistress, show us all how obedient you are."

"Yes Mistress", Bobbi nodded and looking up, stuck out her tongue before giving Natasha's pussy one nice and long lick from bottom to top, moving her head to help with the motion, as Natasha closed her eyes and let out a moan of pleasure at how Bobbi was using her tongue.

God, she was a well-trained pussy licker herself, considering counting out Natasha and Sharon, Bobbi bottomed to everyone as well, and there were multiple women to bottom to, and of course Steve himself.

Bobbi licked again, and then again, and again, using her tongue on Natasha as if she was Maria or Sif, but Bobbi knew it was neither of them, it was Natasha, and now Natasha was making her pay.

"Wow, one sub bottoming to another sub, fun sight", Maria said, fingering herself now by putting her hands in pants.

"Well, being my wife has its benefits", Steve said with a shrug.

"Bobbi seems to be loving it though", Sharon said. "I think she wants to lick Natasha's pussy on her own accord."

"Perhaps she is lesser than even Natasha and is only above her due to her luck", Sif suggested.

"Not gonna disagree with that", Steve said. "I think how this day turns out will show us who is superior out of these two."

Bobbi's licks continued as she kept pleasing Natasha, who moaned in pleasure, and grabbed Bobbi by the back of the head, pulling the bigger woman into her pussy, pretty much suffocating her with it, but Bobbi knew she had to do it, and she sucked on it as well while licking it, and laid some kisses too.

Her pussy-licking training paid off as Natasha let out a loud moan of pure pleasure, and her juices coated Bobbi on the face, who took them all in, gulping them down as that would be required of her. This was like routine to Bobbi now, but being like this with Natasha was humiliating for her, considering how many times she had topped Natasha in the past.

"You did great licking my pussy, bitch", Natasha said coldly once she had recovered.

"Don't think Nat's done yet", Sharon said, now fingering herself as well.

"Oh no, in fact she has just begun", Steve said, pulling down his shorts as he masturbated to the hot sight in front of him.

"Well, now get on all fours", Natasha ordered, and Bobbi seemed a little hesitant. "Now bitch!"

"Yes Mistress", Bobbi nodded submissively and getting up, turned around, then got down on all fours, sticking out her ass for her latest mistress, who just up until last day was her bitch.

How had the tables turned for her so quickly?

"Ooohh, Bobbi's ass is really spankable, I think Nat is in for the time of her life", Maria said. "Lucky woman, getting that ass to herself today."

"Yes, she makes a good slave in the matters of the flesh", Sif agreed, now fingering herself too, and with that, all of them were pleasing themselves at the sight of Natasha and Bobbi.

"You can thank me for that", Steve pointed out, and none of the women disagreed, since he was the one who had turned these woman into his submissive bitches, they all belonged to him at day's end.

Natasha ran her hand over Bobbi's ass, gently stroking it, a smirk on her face. "Your fat ass is so spankable, its like it was made to be spanked. If there is a Creator, he made your ass this way because he knew some people deserve to have pleasure like that." She leaned forward and whispered into Bobbi's ear. "You were born to bottom." She then bit Bobbi's ear, making her wince as Natasha moved back.

"So you beat me in all of our sex fights due to your better durability", Natasha snarled. "And then spanked and fucked my ass so many times, I think that makes a lot."

During that, she was gently caressing Bobbi's ass, and Bobbi was blushing, not that she could see it due to the position, but it wouldn't matter once the action began. Plus, Bobbi couldn't do much about it, because she was Steve's wedding gift to Natasha.

SMACK! SMACK!

Bobbi let out a gasp as she felt each of her butt-cheeks sting and then jiggle in quick succession from the blows Natasha had given to them both one by one.

"Ooooh, well your ass sure loves being spanked, based on how both of your butt-cheeks just jiggled", Natasha quipped, and Bobbi lowered her head in humiliation, to Natasha's delight as she gently caressed Bobbi's ass again, taking its feel, increasing Bobbi's anticipation again.

SMACK!

Bobbi yelped again as her entire ass stung and jiggled from Natasha's blow, which was right over her butt-crack, and she knew it had just begun, so there would be more later.

"A yelp, you definitely love it, and so does your ass, bitch", Natasha sneered as-

SMACK!

Bobbi let out another yelp, her whole ass stinging and jiggling once more, and Natasha wasn't going to let up anytime soon as she raised her hand and there was another SMACK!

Bobbi gasped, biting her lip, trying not to make a sound again, but when Natasha's hand connected with her ass, there always came a sound.

Natasha continued spanking Bobbi for the better part of the next 5 minutes, and every time there was a sound of a blow, the sound of Bobbi yelping or gasping followed, and Natasha unleashed her whole frustration and fury regarding Bobbi into the blows on her ass.

This was one sub who had topped her so many times it was humiliating, but now she would have her revenge. She was having it right now.

SMACK!

Bobbi let out long and loud yelp. This was the 100th spank she had taken on her ass, which wasn't even red anymore, it had taken on a purplish tint at this point, and Natasha's hand prints were all over it.

Now she knew she wouldn't be able to sit properly for at least a week without feeling the stinging pain in her ass, and every time she would feel it, she would be reminded of being in this humiliating position on the ground on all of her fours, with Steve, Maria, Sif and Sharon watching and pleasing themselves as Natasha topped her and continuously spanked her ass a full 100 times. The same Natasha who she had topped herself so many times before.

"Well, you've gotten your spanking, naughty girl, I've disciplined you well, and you better remember this discipline, plus, your ass got even redder than my hair before becoming purple", Natasha whispered into Bobbi's ear, and Bobbi could still feel her whole ass burning from Natasha's hard and long spanking. "I am sure you will remember it every time you sit for a week. Or we can make it longer, maybe I can bend you over some other time today itself, make you take off your pants and panties and stick out your ass, and then spank you again, what do you say, bitch?"

Bobbi gritted her teeth, trying not to give Natasha what she wanted, which was a humiliated 'yes'. Wedding gift or not, she would still hold on to the little dignity she had left inside of her, and so Natasha decided to play this another way.

"Well, I've still got you as my wedding present, so you can think on it, until then", Natasha trailed her other hand over Bobbi's thigh, momentarily caressing her ass again as Bobbi gasped due to the sensation it sent, and then Natasha ran her fingers down Bobbi's ass, eventually inserting two of them all of a sudden right into Bobbi's pussy as she yelped. "You cum like the bitch you are."

Natasha then pumped her fingers inside of Bobbi's pussy, moving them back and forth, up and down, as Bobbi closed her eyes, arching her head backwards, her hair waving, as she let out moans of pleasure, feeling Natasha's fingers hitting her G-spot.

As much as she hated being Natasha's bitch, Bobbi had to admit Natasha knew how to use her fingers there, and in about 2 more minutes, Bobbi let out a long moan of pleasure as she came, and then she panted as her orgasm coated Natasha's fingers, who pulled them both out, and put them in front of Bobbi's mouth. "Come on, take them in like the good little bitch you are."

Bobbi almost didn't want to, but the pleasure she had felt was too much, and opening her mouth, sucked on herself from Natasha's fingers. "Sucking on your own cum from my fingers, you really are my bitch, and no one can deny it."

When Bobbi was done, Natasha got up and walked off, and Bobbi sighed in relief, thinking it was over.

Only Sharon was in a position to see her face and seeing what Natasha was taking out from the drawer, she smirked and told Bobbi. "Oh its not over yet."

Bobbi was about to look behind but Steve ordered. "Don't, it's a surprise."

Bobbi looked into the front, at the smirking Sharon who was fingering herself. Even Sharon, the only other woman she was allowed to top, was having fun at this sight.

She had a feeling what was going to happen to her, but perhaps it was-

"AAAAAHHHHH!"

Bobbi screamed loudly as her asshole immediately made way in a split second, and was full already, Natasha's 10-inch strap-on inside it, having been thrust with such speed and intensity that Bobbi didn't even have time to get used to the sensation.

And with how much her ass still hurt from the spanking, it was going to be even worse.

Plus, Natasha was having her revenge, she wouldn't let up.

"Oh well, Natasha was going to take your ass anyway, better fast than slow", Maria shrugged without any sympathy.

"Now you shall be my bitch truly", Natasha snarled into Bobbi's ear and pulling back, thrust hard as Bobbi let out a loud moan, feeling her ass jiggle from the strap-on moving inside it.

Natasha then thrust again, and Bobbi moaned, before Natasha grasped her tits, pressing them and squeezing her nipples as Bobbi's moans got louder.

Natasha then continued thrusting her strap-on into Bobbi's ass while squeezing her tits.

"Just like that Bobbi, be her slave like you were meant to be!" Sif cheered.

"Yeah, show us all just how much of an ass slut you are, your fat ass was made to take cocks, both real and fake!" Maria added her own two cents.

"Be Natasha's bitch, Bobbi", Steve simply said as Natasha continued pushing into Bobbi, and she came from her pussy due to the pleasure her tits were getting.

Natasha then pulled Bobbi back by the hair. "Do you want to cum, bitch?"

Bobbi didn't respond and got a hard smack on her ass, making her yelp as Natasha asked. "Tell me, do you want to cum, bitch?"

"Y-yes, Mistress", Bobbi nodded, some tears in her eyes at how much she was being humiliated, but deep down she knew she had brought it on herself. If she hadn't thrown her superiority in Natasha's face, then Natasha wouldn't have chosen her as the wedding gift.

"Well then, what are you?" Natasha asked, and on not getting a response, spanked her again. "What are you?"

"I am your bitch, Mistress, your anal whore!" Bobbi said, now broken by Natasha.

"And not just for today", Natasha added. "Forever, you are a wedding gift, Bobbi, I don't intend to return my wedding gift, you are my anal bitch forever, now you belong at the bottom. What do you think about that?"

Oh God! This was the permanent setup now, not just for today, how had Bobbi not realized it? The wedding gift wasn't Natasha being allowed to top her for a day, she herself was the wedding gift for Natasha to use in whatever way she wanted, for the rest of her life.

"Well played Natasha, well played", Maria said, clapping for her.

"I used to wonder how you outplayed Loki with just words, now I do not", Sif agreed.

"So I guess this proves don't mess with the Black Widow", Sharon added.

"Oh hell no! Never mess with her!" Steve agreed before adding. "And Bobbi, you shall bottom to Sharon too. Since she is Peggy's niece, she gets to be over you as well, now you belong to the bottom, you got that?"

Bobbi nodded brokenly. "Yes Master."

"But since you are supposed to be Natasha's wedding gift, if Natasha or anyone else wants to fuck you at the same time, you allow Natasha to go first, even if the other woman is higher than Natasha in the harem", Steve told her. "Since you are my wedding gift to Natasha, this exception can be made, the other women should know it too." Steve then asked Maria and Sif. "You two okay with that?"

"Well, you two are married, so whatever rules you have, I shall respect those", Sif said with a nod, and Steve smiled.

"Yeah, if you want your wife to have all claim over Bobbi, then she can have all claim over Bobbi", Maria agreed too, and Steve nodded gratefully at them both.

"So, what are you Bobbi?" Natasha asked.

"I am your bitch, Mistress, to be used by you whenever you want and in whatever way you want, and all my holes are your property for your use", Bobbi said, now completely obedient, knowing from this moment forth, she was nothing more than an orifice to the Black Widow, something for her to use and abuse in whatever way she saw fit.

"Good, now remember your place", Natasha snarled as Bobbi finally came from her ass, and moaned loudly at the feeling of bliss overtaking the pain from having a big strap-on thrust in her ass so quickly and brutally.

Natasha pulled her strap-on out as Bobbi yelped on feeling her ass go empty, and Natasha commanded. "Now spread your butt-cheeks."

Bobbi nodded and did so, showing her big gaping asshole to everyone present in the room, who were all pleased by the sight, Natasha most of all as this was her handiwork.

Natasha then stood up and ordered. "Now Bobbi, clean my cock of your ass."

"Yes Mistress", Bobbi nodded as she stood up and turned around, then got on her knees, sucking Natasha's strap-on as Natasha grabbed her by the head and deep-throated her, making her gag on it.

"Ooooh, well, looks like this was a great day for Bobbi as she now finally knows her place", Steve said as the other three woman all laughed, and Natasha looked at each of them one by one, sharing smiles, all of them so happy now.

Oh this wedding gift was just the start, she needed to use Bobbi to see if she still had her Super Top alive or not.

And she did, the Super Top had just been buried deep down due to how much she loved being submissive nowadays, offering her ass to Steve and the others.

But she was tired of it now, having done it for over 10 years, it was time to be back on top again. She was Steve's wife, she would be his equal now, not at the bottom of the harem.

With Bobbi below her, it was time to take the rest. Sif and Valkyrie would be hard since they were Asgardians, but Natasha would take all the other ones, starting with the women in SHIELD, and she would end it with her beloved Deputy Director. She may rank higher, but Black Widow would prove she is the superior one, and an equal partner to Steve.

Bobbi gagging on her cock again made her smirk at the thought of just how much she was going to enjoy regaining her old position, and soon the other women would also be in Bobbi's position.

And here's an add-on, Steve's wedding gift to Natasha was Bobbi, HA!

And yes, Natasha now plans to get back on top so she and Steve can be equals, though the process will take time.

But she has taken Bobbi now, and more shall follow soon.

However, this fic shall only have 1 more chapter after this (for now that is), so I'm thinking the Natasha stuff can be more of a little sequel, which I'll get to some time, whenever I want that is.

Plus, she needs to give Steve a wedding gift too, and you shall know what in next and last chapter (last for now).

Hope all enjoyed and see you all next time with another chapter.
