You kissed Kate lazily as she moved her palms up your thighs, guiding your legs further apart and giving you every opportunity to stop her if you were so inclined. You weren't. Watching Kate make Natasha fall apart like that had unleashed a fire in you, and the day was far from over. Kate whined when you rested as she tried to move your fingers from your clit where you were still lazily rubbing. You grabbed the ring in her collar suddenly, tugging her lips away from yours.

"You can do better than that to earn it." You grumbled, making Kate whine again but this one was out of arousal and not frustration. You smirked when Natasha walked up behind Kate, her hands cupping her tits and squeezing.

"I said help your professor cum, mutt," Natasha's horse voice grumbled into Kate's ear, making the young woman shiver. Giving up temporarily on moving your hand, Kate's palms slid across your thighs again, fingernails digging in and scratching as Natasha's hand on the back of Kate's head guided her mouth to your nipples. She sucked immediately, swirling the swollen nub around her tongue before grazing her teeth over it, tugging slightly. You groaned at the sensation, tugging her mouth closer with the finger still looped in her collar. Your thighs spread further as your hips began moving, making Natasha chuckle. Her hands reached around Kate, grabbing your hips and tugging you forward in the chair, giving you friction on Kate's stomach. Kate moaned when your pussy made contact, desperate to taste you, to do what Natasha had ordered her to do. Within seconds, her stomach was covered in your wetness as Natasha manipulated your hips, her mouth moving over Kate's shoulder.

Your hands wrapped around Kate's ass as you tugged her forward further, needing more contact. Your growl of frustration synced exactly with Kate's whines when your hips were roughly shoved backwards and you both lost contact.

"Isn't Doctor Ivanoff so pretty when she's desperate?" Natasha moaned into Kate's ear, which triggered an instant reaction from you both. "You want me to help you fuck her?" Natasha's teeth caught Kate's neck and she bit down hard. You blinked at the suggestion and watched as Kate's pupils blew in real time. You smirked. Your pup liked that idea.

"Yeah, pup? You want to fuck me?" You tugged Kate's collar upward again, catching her lips with your teeth before your tongue slid over hers again familiarly. Kate moaned into your mouth and you swallowed it, grabbing her ass and tugging you against you again. Natasha allowed a heated make-out for a few moments before her hands tugged Kate's hips backwards, luring the younger woman out of your reach. Your fingers lazily returned to your clit as Natasha returned to her bag, fishing a strap out of it and securing it around Kate's hips. Kate stared down at the toy, practically drooling at the mere sight of it, let alone the thought of what she was about to do with it. Satisfied with her handiwork and sliding her fingers slightly over Kate's clit, Natasha turned back to you, smirking.
