Tabitha, the warm and wetness in her crotch growing, straddled Vipress and grinding against the snakewoman. Rick noticed and worked his hand down his wife's body, unfastening her shorts. She stopped grinding long enough for Rick to drop them and her soaked panties while she pulled off her shirt. Vipress let out a hiss of pleasure at the first sight of Tabitha's now naked body.
Tabitha turned to her husband. "That just leaves you" she said as she unbuttoned his pants and dropped his drawers while Rick discarded his shirt. Tabitha pressed her body to his, her wet crotch rubbing tantalizingly against his erect cock, and gave him a deep, lusty kiss.
"Vipress" said Tabitha. "Please lay on the floor. I am going to show you delights which I want you to return to me tenfold with that long, sinful tongue of yours."
The naga tilted her head curiously then smiled. She lay back on the floor. "Show me these delightssss..."
Tabitha gave Rick another deep kiss then turned and dropped to the floor. She kissed her way up Vipress from her tail toward her destination. Vipress' eyes went wide when Tabitha's tongue entered her. "Oh, I sssssssee....oh..."
As the human woman pleasured the snake woman, she raised her backside in the air and gave it a little shake in Rick's direction. He got the hint. Rick got on his knees behind her and slid in. He thrust away into Tabitha as she demonstrated to Vipress that she was a cunning linguist. The naga was practically oozing juices.
