The girl drew back about half an inch, gurgling sounds coming from her. She opened her mouth wide, then pressed her lips into Joan's cunt again, sucking. The sensation sent a ripple of ecstasy through Joan's body. It felt to her as if the girl was sucking every drop of cunt juice from her body.

"Oh, yes, yes!" Joan hissed, grinding her pussy into the girl's mouth. In the back of her mind, she told herself this was crazy, insane, but her body, her cunt, told her different. She glanced toward the door to the doctor's office. It could open at any time, and she would be caught here. Caught on the receptionist's desk, her pants dangling from one foot, legs wide, grinding her cunt into this exquisitely lovely girl's sucking mouth.

She was afraid of being caught, but her pussy was guiding her now. The ecstasy of the girl's lips and tongue made the fear fade.

The girl suddenly fucked her tongue into Joan's cunt.

"Ohhh!"

The girl's tongue fucked deep, very deep. It seemed impossible for a tongue to be so long, yet it seemed to be touching the very depths of her body. The tongue licked at the wet, satiny walls of her cunt, drew back and swirled about her distended clit wickedly. Joan humped her ass up, squealing softly, trying not to make much noise.

The ecstasy grew swiftly as the girl sucked and licked at her cunt. The tongue seemed to be everywhere at the same time – inside her cunt, lapping the puffy, hairy pussy lips, twisting about Joan's intensely inflamed clit. She hunched her ass up, grinding into the girl's face. Her fingers curled around the edges of the desk, gripping until her knuckles were white. She was gasping and mewling, twisting her head from side to side.
