With unequaled stealth, the giant viper slithered her way up the side of the bed and under the blankets. If Tabitha noticed the feel of cool scales against her sexually frustrated body she made no indication of it as she slept on. Remarkable, Vipress thought, that she still sleeps. This close to her, though, her snake senses swam with overwhelming chemical scents. This poor woman wanted sex and wanted it bad. Why deny her? The snake grinned. Her son had turned out to be so much fun. Perhaps Tabitha would be just as rewarding an ally.
Slowly, carefully, Vipress coiled around the woman. Embracing her night gown clad body into her own, restricting the human's movement. Her tailtip remained positioned at a strategic location between the woman's legs. Just touching on her sweet milky opening. The snake gently pressed the tip of her muzzle to Tabitha's ear and whispered gently.
"Wake up, Tabitha..." Vipress hissed. "Meet your new missstressss."
Tabitha woke to the sight of a nightmarish face and haunting yellow eyes staring down at her. She wanted to scream, but she was completely parylized with fear. She immediatly broke into a sweat. Was she dreaming? Was this real???
"Sssssssshhh." The snake hissed gently. "I am a large and powerful sssssnake. My bite will kill you in mere ssssecondssss. If you wake your husssssband I will bite you. Do you understand?"
The middle aged blonde nodded gently, eyes wide with disbelief and then horror. She was awake.
"You're going to get out of bed, Tabitha. Quietly. Then you will take me to the bassssement. Yessss?"
Again, Tabitha nodded.
"Good." The snake praised. "But firsssst, a tasssste of what can happen if you keep obeying me."
Before Tabitha could move, Vipress gently brushed her tail over the woman's pussy. The cool leather of her scales, the texture of her flesh, the softness of the movement, it did exactly what the snake wanted. Poor undersexed Tabitha grew wet. She muffled a cry and bucked into the serpentine tail almost unconsciously.
"There will be more, my ssssweet human. But let'sssss continue with your current tassssk. Yessss? There... I will reward you."
Tabitha blushed now. Deep red. She was scared, confused, but mostly horny. Her temperature began to raise quickly as her loins ached for more of the snake's tail. Dutifully, though, she rose, clutching the viper close to her ample chest, and together they ventured out of the darkened room and into the house.
"M-May I talk now?" Tabitha whispered.
"Yessss." Vipress essed. "You may."
"W-What are you?"
"Your husssssband'sssss handiwork." She grinned. "All will be answered in time, pet."
Tabitha gulped. "Okay. We're going to the basement. Just... don't kill me. Please. I don't want to die."
"Then keep helping me." Vipress nodded. "And remember what I just did to you."
Tabitha shuddered, the memory of the scales touching her loins fresh. She blushed deeper.

Moments later Tabitha had carried the big and heavy snake down the stairs, the heavy wooden door closed and locked behind them. The soft glow of a blue lamp was the only light, giving the "lab" and surroundings an eerie mood.
"N-Now what?" Tabitha asked, nervous.
"Let usssss sssssit and talk here." Vipress pointed with her muzzle towards a soft couch in the corner by some old books.
"O-Okay." Tabitha obeyed, sitting down on the sofa with the snake still wrapped around her.
"Now. Do you know what your Rick doessssss down here?"
"He... he tries to make hybrids." Tabitha gulped. "That is, hybrid animals." The woman paused, stared at the snout of the giant pit viper holding her tight, and the realization sunk in. "My God... he did it, didn't he?"
"He doessssssssn't know yet. And I... need your help."
"MY help?" Tabitha gasped. "N-No offense, ma'am, but I wouldn't know the first thing about..."
"Ssssshhhhhh." Vipress ground her tail into the human's groin again, slowly this time. More sensuously. Tabitha melted in response, slumping back into her seat.
"Oh God!" The woman gasped. "Please! Please, don't tease me like that!"
"I know what you dessssssire, Tabitha. I can pleassssssse you like no man can. Like your own man can. But you need to be honesssssst with me. I tassssste your liesssss." She drove her tail harder, the tip slipping inside of the woman now, parting her labia and slipping within. The mere tip bigger than any penis Tabitha had ever felt. This made her moan, hug the snake close.
"Oh God!" Tabitha gasped. "You're going to make me cum!"
"I know, sssssweeetheart. So take your pick. Pleasssssure? Or pain? Mussssst I hurt your ssssweet flessssh?"
"Okay!" Tabitha gasped again, Vipress's tail thrusting into Tabitha, a little harder, a little deeper each time. "Oh God! Yes! Okay! It's a red notebook. He keeps it in the desk down here."
"Good girl." Vipress nodded. "Keep going." The snake kept going too, now steadily tailfucking the human.
"Ohhhhhhhhhh!" Tabitha grimaced. "I-I'm..."
"More, pleasssse." Vipress withdrew her tail somewhat, teasing the woman.
"No! Don't stop!" She looked at the snake pleadingly, and then realized what she wanted. "The notebook! It has all his experiments. Formulas. Everything he ever found out. Surely it has some value for you. Just, please! Please! Make me cum! Please make me cum! You feel so good! So fucking good!"
"Ahhhh." Vipress grinned. "You want more?"
"Yes!" Tabitha practically screamed, holding close to the snake and trembling.
Too easy! Vipress smirked.
