Kathy was moving crazily, her body jerking while her arms pounded the mattress on either side of her. Marcie frowned. It was strange, weird, and scary watching her cousin go through this. Of course she'd seen her act the same way with the dog. But that was different. Now she was part of it.

"Ohhhhhh!" What was that sensation?

Something very hot and wet was touching her legs. Her imagination? Fighting through the haze of sensation that had dulled her to everything except her own burning clit, Marcie brushed away stray hairs and saw that Pardner had sneaked into the bedroom! He'd climbed onto the bed and now he was mouthing her toes, drawing his tongue up the soles of her naked feet!

"No! Horrible! Get away!" She wouldn't be another experiment for this horrid animal! Jerking up, forgetting temporarily about her own sexual arousal, Marcie raised her right hand, slapping down hard at the beast. "Get away from me!"

Her first blow caught the animal off-guard, slapping him hard across the head. Pardner whimpered, backing down, his tail tucked between his legs. Marcie drew her hand back, watching him with wide, fearful eyes as he wheeled about and eyed her with shock.

Kathy was still humping at the air, her fingers squashing in and out of her tight virgin fuck hole. Pardner eyed the brunette, then turned back to Marcie, having apparently regained his confidence. He started approaching her, his pointed ears pinned back, his eyes slitting while a low growl came from his throat.

"No get away!"

Again Marcie raised one hand above her head. But this time she was less sure of herself. He was growling. The fur around his neck was standing up while his bushy tail quivered, standing straight out from his ass. Her muscles were tensed. Hesitating, the girl drew her ass back, back until it pressed against the pillows.

"No, Pardner… no…"

They had been friends from the moment she'd arrived. But now he was facing her as if she were his worst adversary! She looked down at the dog, her nostrils burning from the air she sucked in.
