But this simply couldn't continue! Lisa told herself that she would have to put a stop to Marge's public display at once, as embarrassing as it would be for both of them. She would be stern but understanding, but she couldn't tiptoe away and pretend she hadn't seen the girl touching herself so wickedly. And it was for Marge's good as well – what if another teacher or girl walked in?

But before she could summon the breath to say something, her facial muscles tightened with newfound horror! The naked girl had removed her finger and was now slowly spreading the lips of her swollen little cunt. The soft wisps of pubic hair covering the tender pink slit were gleaming with vaginal secretions, and now Lisa could see the entire plane of her moist, fleshy crevice brazenly offered in hungering supplication.

"Here Atilla!" the girl pleaded, "Come here and lick me! Ohhh, you damned dog, come here and eat my box!"

The horribly obscene request was beyond Lisa's comprehension! She staggered back a step while she saw the German shepherd obediently rise and move closer, and she attempted to clear her reeling mind and think straight. The nearly overpowering thought that she should now intervene at all costs and put an end to this flagrant exhibition fumbled in her brain. Lord! She had to scream or rush in or something! She had never witnessed such a perverted abandonment of all that was chaste and holy!

But all Lisa could seem to do was shudder from the perverse stimulation that indulging in something forbidden gives, even against one's will. She watched in fascinated revulsion as the girl's head rolled back and forth on the bench, contorted with the faraway stare of erotic obsession, while the dog sniffed closer along her trembling young thighs. "Yes… yes, Atilla, lick me out good, you marvelous dog! Ohhhh…!"

The huge snout of the dog inched still closer, and then his long red tongue darted out and obscenely licked along her inner leg.
