Before Rick could make a move, Vipress slithered over to Tessa. "Please, allow me..." she said.
Vipress lowered herself onto Tabitha, wrapping her tail around her new fellow naga before sliding her sinuous tongue into Tabitha's vagina. Rick watched Vipress pleasure his wife and listened to her moans of ecstasy.
Even as the action kept him aroused, Rick realized Vipress' motivations: the snake was saving him for herself. Vipress had been denied earlier, but now with Tabitha's eager involvement there was nothing to stop them. Yet Tabitha's transformation had introduced a new variable. Vipress' transformation seemed not only permanent but contagious. Was Tabitha's as well?
One great final moan from Tabitha signaled the conclusion of the two snakewomen's intimate encounter. Vipress raised herself up and released Tabitha's tail. Rick went to his wife's side. Her face wore a dreamy expression.
"Tabitha, dear, how do you feel?" Rick asked.
"Delightful" she answered.
Powerful arms picked up Rick from behind and dropped him on his back on the nearby bed. Vipress loomed over him, smiling. She lowered herself toward Rick.
"You desssire me. You have ssssince you ssssaw my new form." Then she repeated her words from earlier: Touch me. Run your human fingersssss over my delicioussss ssssscalesssss. Pleassssse me."
Rick touched Vipress' face, running his hand gently along her cheek. He marveled at her beauty. They kissed, more passionate than when this tryst had started. He felt her tail then her vagina rub against his dick , her juices dripping on him. He wanted her.
Placing his hands where Vipress' hips would be, Rick impaled the naga on his waiting erection.
