AN: That's it for smut for now. Next I'll focus on the main story again.

"Get on your fours. I'm gonna take you from behind," Tony ordered.
Yelena turned over quickly and raised her hips high up in the air. She grabbed her butt cheeks, spreading them apart, giving him a good view of her puckered asshole and her wet pussy. Tony placed his tip at her entrance, rubbing it around her wetness a few times, and then slapping it against her clit. This made Yelena moan loudly. She was ready for him.
She needed him inside her right now.
"Please, Tony," she pleaded. "I need you inside me."
Tony pushed forward, sliding his cock into her pussy. It felt like a velvet glove, wrapping tightly around his cock, sucking him in. Then he felt her hymen break under his strength, making Yelena cry out in pain.
"Ahhhh!" she screamed.
"Sorry," he apologized, kissing her neck from behind.
He gave her some time to adjust to his size, letting her get used to the feeling before moving again.
"I'm okay now," Yelena reassured him. She was a tough girl after all.
Tony started fucking her slowly. Her pussy felt amazing. She was so wet that his cock slid in and out easily. His hands were resting on her ass cheeks as he fucked her harder and faster. He spanked her occasionally, making her gasp in surprise.
"Harder!" She cried out. "Fuck me harder!"
Tony obeyed her command, pounding her cunt even harder than before. She moaned loudly as he ravaged her pussy. He grabbed her hair, pulling her head back while continuing to slam into her.
"Oh my God! Ohhhhhhh~!" Yelena screamed, enjoying every second of it. "Yes! Fuck me! Fuck me harder, Tony!"
Tony slapped her ass, causing her to yelp in surprise. Then he pulled out and flipped her over onto her back. He climbed on top of her, grabbing both of her legs and pushing them towards her chest, exposing her pink pussy once more. He guided his cock to her entrance and pushed deep inside her, burying himself completely within her tightness.
Her eyes rolled back in pleasure as he began thrusting wildly in and out of her. She wrapped her arms around his neck and pulled him down to her, kissing him passionately while he continued to fuck her mercilessly. While Natasha began to rub her clit once again, enjoying the show.
"Oh fuck! Fuck me! Oh God, I love your cock!" Yelena gasped as Tony pounded into her relentlessly. She kissed him again, moaning into his mouth as their tongues danced together. He broke their kiss and grabbed onto her breasts, squeezing them roughly.
She bit her bottom lip as she gazed up at him lustfully.
"Slap me," she requested suddenly.
"What?" He asked, surprised by her request.
"Slap me, please. I want to feel pain while you fuck me," she pleaded.
Tony obliged her request and smacked her across the face. Her head snapped to the side from the impact, and then she turned back to look at him, a big grin on her face.
"Harder," she begged.
He slapped her again, this time harder than before. She groaned in pain, but it quickly turned into a moan. Her pussy tightened around his cock, causing him to groan as well.
"Mmmmm... Yes~" She moaned softly.
He then grabbed her throat tightly, choking her while continuing to thrust into her. He leaned forward and whispered in her ear, "I'm gonna make you squirt like a freaking broken faucet."
Yelena laughed and then moaned loudly as he increased the speed of his thrusts. His balls slapped against her ass cheeks with every stroke.
She wrapped her legs around his waist, pulling him closer to her body and encouraging him to fuck her even harder. He obeyed her wishes and fucked her faster, harder, deeper.
His balls were slapping against her ass loudly, echoing throughout the room.
She was enjoying the way he was choking her, as well as the sensation of being fucked so roughly. She felt like she was losing control over herself. But she liked it.
"Oh fuck, yes!" Yelena's eyes went toward Natasha who was fingering her cum-filled pussy, "Do you like watching me get fucked? Do you enjoy watching me get dominated by this big cock?"
"You are such a machoist slut," Natasha replied, not stopping fingering herself.
"So are you," Yelena laughed.
"Yeah... but you're worse than me," Natasha shot back.
"Who cares as long as we are having pleasure? I... oh! Shit! Mumm~" Yelena couldn't finish her words as Tony left her throat and squeezed her nipples that made her shudder in pain and pleasure, "Shit! I'm coming!"
Yelena cried out as her orgasm crashed over her, sending shivers throughout her entire body. Her pussy tightened around Tony's cock and her legs wrapped tighter around his waist, pulling him deeper inside her as she came hard.
He kept thrusting into her, fucking her through her orgasm while twisting her nipples roughly. She screamed in pleasure as her climax continued to intensify. She never experienced anything like this before.
Tony pulled out his cock and looked toward Natasha.
"You are still horny after that, huh?" He asked her with a smirk.
"You bet I am," Natasha replied, smiling seductively. She spread her legs wide open for him and speed up her fingering, pushing his cum in and out of her pussy. "I want more, Tony," she begged. "Give me more."
"Hell no!" Yelena pushed down Tony and saddled him. "You got your fuck. Now, he's mine." She quickly slammed her pussy down on his cock. "Mmmm... Oh my God! This feels so good~" She moaned as she bounced up and down on top of him.
"Shit! Haha..." Tony chuckled, "So impatient."
"Sorry about that. I can't let her have you all by herself," Yelena explained as she continued to ride him. She was very aggressive and seemed to really enjoy the feeling of his cock sliding in and out of her. "Ohhh~ Ahh~" She moaned loudly.
Natasha couldn't help but smile at how jealous Yelena was acting. It was cute.
Yelena was jumping up and down. She was going up till the tip and slamming her pussy down. Each time she did, Tony could feel her inner walls clench down upon him. The sensation was incredible.
"Holy shit! Keep doing that. Faster... Don't hold back," Tony said watching her boobs jiggle in front of his eyes.
Natasha's thighs trembled as she came once again from the sight of him fucking Yelena.
Yelena continued to bounce up and down on top of him, moving faster and faster. Her breathing was becoming labored, and sweat poured down her face. Both their enhanced body were going at the pace a normal human wouldn't be able to match and break. The speed, the strength, and the stamina were all above them.
"Fuck! I'm getting close," he warned.
"Me too!" She cried out. "I want to cum with you. Come on. Let's do it together."
Tony grabbed her hips and began thrusting up into her, matching her movements perfectly. Their bodies moved as one as they both neared their climax.
"Come on, Tony! Cum inside me! Fill my pussy up!" She yelled.
"Here it comes," Tony warned her.
"Do it! Please! Please, I need it. I want it! Give it to me!" She begged him desperately. "I'm gonna cum too! Oh God, I'm gonna cum with your cock inside me! Yes! Yes! Yeeeeees! Aaaahhhh~!!" Yelena screamed out loud as another orgasm hit her.
Her body shuddered as she came all over Tony's cock. She felt him release inside of her, filling her pussy completely with his warm seed. She collapsed on top of him and buried her face into his neck while she continued to come down from her climax.
"Huff! Hufff!" She panted heavily, trying to catch her breath.
"Did you enjoy that?" He asked her.
"Yes... Thank you," she answered between breaths.
Natasha was still watching them, but now she had stopped touching herself. She just watched as Yelena rested on Tony's chest, both of them covered in sweat.
Tony looked over at Natasha, who was staring at them intently.
Then Yelena slowly stood up and instantly felt all of Tony's cum dripping from her pussy onto his cock and some even trickling down her thighs.
"Wow! Look at the mess we made," she said, laughing slightly.
"Get down and lick my cock clean," Tony ordered.
Yelena obeyed him without hesitation. She bent down and took his cock in her mouth, licking it clean of their combined juices. She made sure to lick his balls and shaft thoroughly, making sure she didn't miss any spots. When she finished, she looked up at him and smiled.
"There. All clean now," she announced proudly.
"Phew! You are awesome, Yelena," Tony complimented her and then turned to Natasha. "And you are one horny redhead."
"What can I say?" Natasha shrugged, "I've been holding back all these feelings and frustration for over two years. And now, I have an opportunity to finally let them out."
"Well, we should have done it sooner," Yelena laughed. "If I knew it would be this much fun and so freaking good, I would've probably jumped on you earlier."
"It's fine. We'll have plenty more opportunities to make up for lost time," Natasha assured her. "So... whose pussy was tighter?"
Yelena looked at Natasha curiously.
"What?" She asked.
"Which of us has the tighter pussy? Which one feels better?" Natasha repeated her question.
"Oh..." Yelena blushed slightly. She then looked at Tony, and her hands grabbed her balls. "So, Mr. Stark, how does my pussy compare to hers? I know I was tighter because I am younger than her." She slightly squeezed his balls with a sly smile.
'Oh, boy! What kind of competition will this turn into?' Tony wondered.
"It was a tie," he replied truthfully. "Yeah, a tie..."
There was no way he was going to start another war between them, and Yelena got his balls in her hand, which she was squeezing gently. But that gentle squeeze could quickly change into a painful one if he lied.
"That's a sly answer. But alright. If it's a tie, then we need to do some more testing," Yelena suggested. "Don't we, Nat?"
"I'm down for it. What do you say, Tony?" Natasha agreed with a seductive smile.
"Sounds good to me," Tony answered, feeling excited already.
"Alright! Let's wrap up the ongoing mess, and then we can... You know, test some more things."
"Sounds like a plan," Yelena said as she stood up, and her legs trembled. "Shit! I think I need to sit for a while."
"You okay?" Tony asked her, concerned.
"Yeah, I'm fine. I just got a little dizzy for a second there. And my legs feel like jelly." She explained. "Must be because of all the excitement from earlier."
