Those who don't try, fail

Rachel stood as Hazel turned to grab her skirt. As soon as the doctor bent down to grab it, Rachel grabbed her hips from behind. The doctor was a little startled, causing her to stumble. She quickly grabbed the counter to keep herself steady, looking back at her patient.

"Rachel? What are..?" She trailed off as the girl pushed her dick against Hazel's ass. She started to grind against her panties, causing the older woman to moan softly.

"Rachel... we can't..."

"But you just said to do what I'd like so long as I don't **** someone, doctor... and I'm pretty sure you want this."

Rachel pulled back before she lowered her dick and pushed the shaft between the doctor's legs. She started to grind between her thighs and against her panty-covered slit, making Hazel moan a little more.

Hazel wanted, more than anything, to pull her panties to the side and let the girl enter her. But she knew it was risky. She spoke softly, her voice a little shaky with pleasure. "Rachel... as much as I'd like to... I'd scream as soon as you put it in... and your mom is right outside."

As Rachel started to think maybe she wasn't meant to be a controlling woman like the doctor described futas to be, the doctor kept speaking.

"But I want to help you still... move back a bit..."

Rachel complied and let go of Hazel, pulling away from her. The doctor took a second to catch her breath, her legs still shaking a little. Then she turned and faced her patient.

"I'll give you a lesson in self-control. I'm gonna take off my panties and lay down on the examination bed... you're gonna put your cock between my thighs and grind against me until you cum... but if you lose control and put it in my pussy, we stop and you will lose my help from now on... clear?"

Rachel couldn't believe what she was hearing. On one hand, she thought there was no way she would lose control like the doctor was talking about. She loved Hazel as her doctor and would never do anything to lose her.

On the other hand... she'd felt the urges before... unable to control herself... would she be able to stop from just putting it in and fucking the doctor? Should she even take the risk?

"Well?" Hazel asked as she slipped the panties off of her, revealing her glistening pussy. It was clear to Rachel that the doctor really did want to fuck... but Hazel was still in control of herself. She wouldn't let Rachel just put it in, no matter what she said or did.
