Marcie wanted to turn and run. But something kept her there, standing in the doorway, clutching her tits as the moans increased in volume. She pushed the door open a few more inches and caught sight of Kathy. There, stretched prettily out on the large bed was the young brunette. Her chestnut-colored hair was fanned out behind her head. Both legs were spread widely apart, one bent at the knee and raised slightly so she could pet the animal on the back with her toes. Long streaks of saliva glittered as the animal licked up and down her slender body.

Pardner, the three-year-old German Shepherd, was merrily licking the girl's pussy. "Oh yes, yessss," Kathy hissed, closing her eyes and rolling her head from side to side. Marcie thought she'd faint from the horror of the discovery. Once or twice she'd heard about women who did this kind of thing. Marcie remembered overhearing some boys talking about some club in Mexico where women fucked with animals. But her own cousin, her very own cousin was there stretched out on a bed, letting an animal touch her pussy with his tongue. And how she was enjoying it! Her face was a mask of obscene pleasure while her body rocked under the tender licking of the German Shepherd.

"Your tongue's so hot, Pardner! Oh, it's so very hot and wet," Kathy moaned, raising her other leg, then letting both slip back down to the mattress.

In another moment, Marcie realized she was moved by what was happening under her horrified, widened eyes. Standing there in the doorway, the young girl felt a kind of hot, itchy tingle becoming worse and worse with each passing second. It was making her cunt shiver, tighten and get warm and moist as she watched Kathy writhe under Pardner's cunt-licking. Marcie found her knees rubbing together while her panties were growing damp around the crotch panel. Her nipples were getting very stiff and hard against her blouse. Instinctively the teenager moved one hand up, rubbing her fingers against the itchy nubs.
