Natasha had just gotten back from a mission and was exhausted. Y/N was bored and had been waiting for Nat to please them. Nat got annoyed and then tied Y/N to the bed frame. The vibrator and with orgasm control.
(Nat and Y/N got into a fight, but it was the night they usually tried different kinks. Nat had a small controllable vibrator that Y/N had control over. Y/N was really pissed at Nat and put it on high. The team started to notice and Nat excused herself to the bathroom. The team didn't know that they had been fighting so they told Y/N to go check on her since they were dating. Nat tries to please herself but Y/N restrains her and doesn't allow it. Bucky goes up to the bathroom door and knocks asking if they're alright. Y/N says that Nat just isn't feeling well and to not worry. Y/N takes out a ball and gag and uses it on Nat to keep her quiet.)
After Nat had gotten back from the mission she was a bit tired and she knew that her girlfriend, Y/N would be disappointed. Tonight was the night from every other week that they would try out different kinks to find out what they liked. It was supposed to be a ball and gag with a small vibrator that Y/N would control. Y/N wanted to skip dinner to make sure that Nat was OK, but Nat was ignoring her. When Y/N tried to find out why Natasha lashed out at her and said she wanted to be left alone. Forgetting that the small vibrator had already been put inside of her pants Natasha left to go cool down. Y/N was scrolling through her phone and as she realized that her phone was dying she started closing apps. When she saw the app to control the vibrator she decided to open it to see if it was still connected. Upon seeing that it was connected she put it on high and plugged her phone in. At dinner, they both realized no one knew that they were fighting. Y/N pretended to get a text-only to turn the vibrator higher. Nat started struggling to contain her moans and sent Y/N pleading looks. Y/N just started talking to Bucky about training. Steve asked Nat if she was okay and Nat shook her head no before running to the bathroom. Sam noticed and told Y/N that she should probably go check on her. When Y/N got closer to the bathroom Y/N could hear her moans getting louder and louder. Y/n opened the bathroom door and Nat tried to cover herself but failed. Y/N pulled out the ball and gagged before whispering "We can still have fun baby," in Natasha's ear. Nat lets out a moan as a shiver goes down her spine, which allowed Y/N to put the ball and gag on. Nat tries to pleasure herself before Y/N moves her hands away and ties them behind her back. As Nat struggles and tries to get free Y/N licks a stripe from Nat's stomach to her throbbing pussy. Feeling Y/N Nat begins trying to buck her hips up for more friction while Y/N holds her hips down and continues teasing her clit. Y/N hears
footsteps and then a knock on the door. "Is Nat alright we can hear light moans and we just want to make sure you're both alright," Bucky says. Y/N responds and says that they're both fine and Nat just doesn't feel well and that they'll be put shortly. Y/N slowly moves back to Nat's clit before starting to eat her out as she holds Nat's hips down. As Y/N notices Nat is nearing her climax she stops and makes herself look presentable again. After she fixes her makeup and hair she unclips the ball and gag before carefully removing it allowing Nat to let out a heavy sigh. She unties Nat's hands and helps her stand up. As Y/N returns to their shared room to get clothes for Nat she sees that no one is at the table and it is now eleven o'clock p.m. Once Y/N is back in the bathroom she helps Nat get dressed after being sore from sitting on the floor for so long. As Nat and Y/N go back to their room Nat asks Y/N for cuddles, Y/N says yes as Nat makes grabby hands so that Y/N will hold her hand as they walk up the stairs. Nat then asks Y/N if she's still mad at her to which Y/N responds with a simple "No".
