The huge snout of the dog inched still closer, and then his long red tongue darted out and obscenely licked along her inner leg. He teased the teenager's smooth creamy skin, arousing her to an unreal reverie of passion, her eyes staring inward at the sexual delights that were coursing through her inflamed loins. The German shepherd was running his tongue over the gentle swell of her buttocks now, taunting her as if it had been trained by Don Juan himself in the arts of love.

"Ohhhh shit!" Marge groaned uncontrollably. "Higher, Atilla, higher! Sink that tongue of yours right in my twat!"

Lisa watched in transfixed horror, unconsciously licking her dry lips with her tongue as she saw her student urgently spreading the pink cuntal lips still wider. Through the moisture, the curling damp hair and the bright quivering pussy lips, Lisa could see the erected tip of the girl's clitoris glistening with succulent desire. Then Atilla raised his head, and his tongue flicked forward to flutter lightly over the trembling bud that nestled in the raw wetness of her open pink slit. Marge's body jerked spasmodically at the sensational shocks of pleasure that pierced through her nubile flesh, and she automatically began to roll her hips back and forth in an obscene rhythm to match the animal's tonguing of her cunt. Her tightly clenched teeth could not suppress the agonizingly delicious mewls of passion that rumbled from her throat, making her sound even more sensuous and abandoned with each undulation of her writhing thighs.

Hypnotized, the older woman stared at the girl twisting to the obscene licking between her legs. Never! Never before had she imagined that such terrible depravity existed! She had heard of men who sometimes bent a girl to their will and forced her to submit when they put their mouths down there… but Marge Spanner was craving it, begging for it in no uncertain terms, and, worst of all, from a dog! It was so horrid, but at the same time mystifying, to the divorced teacher, how this cherubic girl was allowing it to happen… and enjoying it! Lisa had found a certain measure of empathy when she'd been watching Marge masturbating, something in the girl's lost glassy stare having reminded her of when she would writhe from her own exciting touch.
