Bucky Barnes/Sebastian Stan One Shots

She's Not Been Mated

Bucky had been away on a mission for two months with Sam when he came back to the compound. He walked into the training room and saw a red head training with Nat and said "Steve who is she?' as his alpha senses kicked in as he smelled the omega of her.

"oh that's Brielle Cooper. She's new Nat came across her during a mission recently. She's an omega too." Steve said

Brielle could sense Bucky's eyes on her and she said "Nat whose that with Steve?'

"Oh Bucky and Sam are back. That's Bucky Barnes." Nat said 

"Oh.. um I need some air." she said as she walked outside

Steve and Bucky walked over to Nat and Bucky said "Where did she go?'

"She said she's needed some air.." Nat said

"Is she ok?' Bucky said

"She's just a little nervous that's all..she's not been mated with." Nat said 

"She's a virgin Omega." Bucky said

"Well yeah.. she's not really sure how all this works. Her parents gave up for adoption when she was born and the adoptive parents aren't like us." Wanda said as she came over.

"Does she know what she is?' Bucky said

"Yeah in some aspects yes.." Nat said

Bucky walked outside and sat beside her and he said "Hi Brielle I'm Bucky." 

"Hi" she whispered 

"Don't be nervous I won't hurt you." he said 

She looked down and he said "Brielle do you know what you are?'

"A omega" she whispered 

"No one has touched you either." he said

She shook her head no and whispered "Still a virgin." 

He made her look at him and he looked into her eyes and he whispered "Don't be afraid. Has the girls explained to you about being an omega." 

She shook her head yes. 

Bucky got up and went into his room. "Steve" he said as he came into Bucky's room.

"Yeah Buck.." Steve said

"You have a problem with her." he said 

"What is that?' Steve said

"She's about to have her first heat?' he said

"You could sense it?' Steve said

Bucky started to make a nest in his room and he said "yes..I don't want to scare her I need you tell Nat." 

Steve went and found Nat in their little guest house making dinner for their kids. "Nat we have a problem?'

"What's that?" she said 

"Bucky said he could sense that Brielle is about to go into her first heat." he said

"Oh god..um well do you think it can wait till in the morning for me to talk to her." she said

"Maybe." he said. 

Bucky finished his nest for her in his room and went to bed and hoped that Brielle's heat could hold off till tomorrow so Nat could talk to her. The next morning Brielle was making herself a bowl of oatmeal and she started to feel a twinge in her stomach then that twinge grew bigger as she dropped her bowl and screamed out in pain. 

Bucky woke up as he heard her scream throughout the compound. He went running and saw her spilled oat meal and her doubled over in pain and he picked her up and he said "Come on darlin..I know how to make the pain stop." 

"Mmm Bucky this hurts what is happening?' she said 

He took her into his room and he locked the door and laid her in the nest he made her and took all of her clothes and he said "I'm sorry darlin. I have to give you my knot ok." 

He played with her for a few minutes to get her lubed up and he kissed her lips and whispered "sorry darlin." and he pushed into and started to fuck her and he whispered "God baby you feel so good mmm it's like you were made just for me baby." 

He started to get faster with each thrust and then he said "You ready for it baby I'm gonna give you my knot baby." then he spilled into her and the pain quickly subsided and she looked up at him and he said "Shh it's alright dollbaby you are mine now.." as he sucked on neck. 

*3 months later*

She was on a mission with Bucky during a team mission. She leaned up against the wall and she started to throw up. 

"Baby are you alright?' he said

She started to puke more and more then he said "Guys cover me and Brielle she's sick." as he picked her up bridal style and carried her to the jet and gave her a puke bag. 

"Baby when was the last time you had a period?' he said

She looked over at him and swallowed hard and she looked down at the floor and said "I don't know." 

They got back to the compound and Dr Cho said "Yup she's definitely pregnant about 3 months pregnant and due in June with 2 babies." 

Brielle said "Wow that didn't take long." 

"Normally doesn't Brielle." Nat said 

She looked down and Bucky said "It might be best if me and you take some time away baby. We can go to Wakanda for awhile." 

"Ok." She said 

They packed up and went to Wakanda and ended up staying there long after their twins were born and had two more babies.
