Panting, drenched in sweat, Brendan bit his lip and grunted as the snake rode on top of him, helping both of them along by pressing her cloaca into his groin, driving his dick deeper, and receiving her own pleasure with each stroke as he filled her. She grew tight, her thick blue coils suddenly squeezed him with unimaginable strength as she tensed into her second orgasm in such a short span. Her head raised into the air above him, she let out a terrific hiss of release, and then pitched forward, gasping for breath. Feeling her clamp down on him with her sweet warm snakeflesh, Brendan finally relented his juices, unable to hold on, and then finally, together, snake and human collapsed in post orgasmic stupor.
Gently, lazily, Vipress loosened her death grip on her slave and coiled further around his body, her slit slipping off his shrinking penis with a slight juicy slurp. For a cold blooded reptile such as Vipress, the heat from Brendan's still excited body was the most comforting feeling in the world. She wrapped herself around him completely, covering most of his flesh, and her scaly cheek rested against his.
"God." Brendan finally whispered. "That was so wrong."
"It pleasssed me." Vipress hissed, nuzzling her slave's soft skin. "That isss all you sssshould concccerrrn yourssself with."
They enjoyed each other's company for a time, basking in the warm and delicious afterglow of their strange serpent/human coitus. Though still buzzed, Brendan's thoughts turned to the consequences. He had fucked an animal, hadn't he? And what of Rick? How would he explain all this?
Vipress sensed his change of emotions and she slid her tail up and down his leg reassuringly. "Remember how good I felt. If you ssstay loyal to me, you can have that whenever you'd like." She paused and smiled next to him, catching his eye. "My ssssslave."
Brendan brightened slyly. It had been the most satisfying fuck of his life, for sure. "Yes, mistress."
She uncoiled from him slowly, the sensual body heat waning, and laid next to him as Brendan drifted off to sleep, spent.
Vipress took a moment to reflect and smiled at the fresh memory of seducing and dominating the young human. She was huge, powerful, and totally in charge of her own destiny. She could do what she wanted and strike down those who opposed her. It was a new and exciting prospect - the sheer sense of godlike power was overwhelming for her. Like Brendan had said, no person would oppose her.
After a while, her mind turned back to the potion. The source of her strength. It would still wear off, she considered. Perhaps a direct dose would prolong her state, as seemed apparent, but it was impermenant. She would still risk shrinking back down to her original size and intelligence. It was only a matter of time.
She slid forward on her belly, lowering her bulk off the edge of the bed, and slowly slithered to the floor. At the foot of the bed was the uncapped bottle of pink liquid. She examined it carefully - barely enough to sustain her for another day if her hunch was correct.
The father would have to make more. That meant she still needed Brendan - means to an end - but most importantly, she still needed Rick.
A sudden vibration shook through the organic sensors of her body and Vipress raised in alarm. Another vibration, then another. Somebody was moving in the house. Suddenly, the iron cold instincts of the pit viper's better nature leaped into action.
She looked around frantically, she couldn't afford to be caught. Not now. She would be made captive again, experimented on, or worse. Certainly she was strong, but Rick couldn't afford to know his potion had worked. He had to remain unaware for her benefit.
Footsteps began tromping up the stairs and in a panic Vipress violently bolted under the bed. Her sheer size made hiding anywhere else impossible.
The door swung open just as her tailtip bolted under the bed frame. She coiled, and waited. Hopefully her slave would know better than to cross her.
She tasted the air carefully and her eyes narrowed in anger. It was him. Her captor. The creator. Rick. Older male, smug, hopelessly self important. And apparently completely impotent.
Her eyes widened in horror as his feet stopped inches from the bottle of potion at the end of the bed.
