"But you wanted to, didn't you?" asked Tabitha, her voice curious rather than accusing.
"You've seen what she looks like. What man wouldn't?"
Tabitha wrapped her arms around Rick. "Some women too" she said before giving him a long passionate kiss.
When it ended, Rick asked "Are you suggesting a threesome?" His wife had never suggested something like that before.
"I dropped Brendan off at a party before I went shopping. It's just you, me, and a sexy snake woman. And we're all horny."
" Vipress, would you join us in the next room?" Rick called out.
The bathroom door opened and the naga slithered out. Rick and Tabitha both looked her over carefully, really taking in her new form. She was about twelve feet long now, three quarters of it tail. The tail at its widest was about as big around as an adult man's thigh. Her scales were dark blue, her belly plates and stomach scales a lighter blue; the transition occurred where here thighs would be. Her puffy vaginal lips were clearly wet with more than just water. Even with a humanoid torso, her body was still hairless and covered in scales. Her torso was a figure that would make models envious. Her scaly breasts jutted forward like two great melons. Her hands looked almost human except for the scales and small claws in place of nails. Her neck was longer than a human's. Her head looked like a human's, but without ears or a nose - only small holes where those would normally be. Her eyes still had the vertical pupils of a snake. The scales of upper body glistened from the shower.
Vipress flicked her tongue out, still forked like a snake but almost as thick now as a human tongue. Her toothy smile showing teeth that were almost human, except they were all pointy like incisors and two on her upper jaw were longer than the rest - clearly still fangs.
"I taste lust in the air" she said. "From both of you."
"Earlier you asked me to experiment with your new body" said Rick. "Would you like it if the three of experimented together?"
Vipress smiled. "That would please me greatly."
