Kate was still limp in your arms in the morning when your alarm went off. When you tried gently moving her off of your chest, she whined and clung to you tighter and you grinned, your lips pressing tightly to her forehead. She smiled in her half-sleep and you extracted your arm, sliding out of bed. It was going to be a long day, and you still had to make sure that Kate felt safe and understood what was about to happen. By the time you were dressed and slipped back into bed, Kate had woken enough to curl herself practically on your lap, her fingers lazily tracing your legs. You gave her about three seconds until...Kate's eyes snapped open at the feeling of the material beneath your fingers. You were wearing a suit. A 3 piece, to be specific. It was a big day. Kate's eyes widened immediately as she took a good look at you for the first time, wiping some drool from the corner of her mouth. You weren't sure if it was the suit or the sleep or both.

"What's..." Kate's voice trailed off as you pulled her into your chest and kissed her hair. She listened intently as you connected the dynamics of your relationship with the larger picture in Natasha's circle. Kate knew the rules. Everyone knew the rules – it was one of the first serious discussions that you had with a new pet. And to violate one of those rules, let alone one of the most important, was just something that wasn't tolerated. Your contract with Natasha, and thereby your relationship that you had worked so hard to train into your pet, was put in danger and no one was going to stand for it.

Once Kate had been informed of the basics, you answered a few questions before pinching her ass suddenly without warning and making her yelp in surprise. You scooted the pup out of bed, selecting an outfit that highlighted Kate's strengths and complimented yours. You both made it out the front door just in time for Natasha's driver to swing in front of the building to pick you up. Kate's hand found yours on the silent drive over. Natasha had ears everywhere, and you weren't about to open up in front of her staff. The time passed quickly, Kate squeezing your hand anytime she felt you tense in preparation for what was to come. You helped Kate out of the car and you both paused to take a deep breath before marching with resolve into the large doors.

"In here." Natasha's voice was pure venom and you followed the sound into the study. Wanda was, unsurprisingly, tied up like a present, hand bound behind her back, collar on tight around her neck, leash dangling. She wouldn't even look up from the floor. You approached Natasha's desk and she lowered her feet off of it, sitting up straight as you approached. Five feet away, you stopped and clasped your hands behind your back, staring into Natasha's violently green eyes. Kate stopped just behind you. Wanda wouldn't look at her either.

"Natasha." You nodded curtly at the woman in front of you before catching eyes with Yelena standing beside her. The blonde smirked and started mouthing something to you in Russian but Natasha elbowed her in the ribs and cut it short.

"Please accept my profound apologies for the behavior of my pet, Professor Ivanoff." The corners of her mouth turned upwards, but there was nothing friendly about her tone. "You have 24 hours before she will be collected. No permanent scarring on that pretty face."
