She Wants To Play With The Kitten, Of Course!

Katie could feel the warm water trickling down her hands, as she was washing the last few dishes. She couldn't help but think how nice it would be to add some moisture to her already wet clit. She looked around the room again, Katie could feel her face grow flush, her breathing started to get heavier.

"Fuck it." She thought to herself. She couldn't contain herself anymore, and she dropped the sponge and dish.

"I need this." She muttered as she slowly moved her hand down the dress, and under her panties. She was immediately surprised, as she felt that her pussy was already dripping wet.
She couldn't remember the last time she was this wet, and she couldn't wait any longer, so she immediately found her clit and began to rub. She closed her eyes, and let the pleasure envelop her body, as she was gently massaging her swollen nub.

"~Mmm..." Katie moaned. She moved her other hand to one of her enlargened tits. She began to pinch and pull her nipple, and could feel a semi-sticky liquid come out of her breast. The doctor wasn't wrong, she was filled with milk.
"What the fuck.." she said in between heavy breaths. She couldn't help but play with her nipples a bit more while using her other hands to rub her clit. She could feel her body start to quiver and her breathing began to get erratic.

"~Ooooh..~"
She knew that she was close, but before she could reach her climax, a voice startled her, and interrupted her ecstasy.

A voice from behind her spoke, "I see you've been busy."

Katie immediately turned around and looked up, and saw Dr. Verlax standing at the doorway, arms crossed. He was looking right at her, his glasses reflecting the light. She was shocked, she didn't hear him enter, and he had obviously seen her playing with herself.

"Oh my God!" Katie quickly removed her hand from under her dress and pulled her dress back down, trying to regain composure.
"I'm so sorry." She apologized.

"There is no need to apologize, dear. In fact, I'm flattered that you're so aroused. I'm also quite pleased that you decided to not leave, and that you are following my rules."

"Huh?"

"Yes. I've instructed you to wear the dress, and clean the dishes, and you've complied. I'm glad you're such a good listener, it means the serum I've given you makes you quite susceptible to my suggestions. However, I can't have you masturbating, as much as I enjoy seeing you do it, it will hinder my research, there is a time and place for it." The doctor smirked.

"Oh. I'm so sorry." Katie replied, she was still embarrassed.

"No need to be, I know you couldn't help yourself. It's the effect of the hormone production, it causes you to have a higher libido, I suppose it is even higher after you have eaten as well. Your body knows it's able to accommodate a growing fetus when it is nourished. So, if you were wondering why you are so aroused, you know now."

Katie became red as a tomato, "Is that why you made me breakfast? For another observation?"

Dr. Verlax smiled. "Of course! What other reason would there be? Now, go upstairs and and clean yourself up. If you smell like sex while we're working, it's going to distract me. Go, wash up. When you're done, go to my study. It's down the hall, second door on the right."

Katie, still red in the face, heads upstairs.
