Zach's snake was still inside Ninia, so when she got on top, she orgasmed once again because of a different pleasure.
The feeling of riding his snake was entirely different from when she was lying down. She could feel his tip reaching all the way to her womb, bringing her further pleasure.
"Anh~ Yes~ Yes~ Yes! Why does this feel different~? We are doing basically the same thing, right?"
"That's the magic of dual cultivation," Zach responded with a grin.
She rode him like an amateur, although she was simply going with the flow to satisfy her thirst. Occasionally switching from pure up and down motions to rotating her hips. Combined with the way her cave massaged him and began taking the shape of his snake, Zach couldn't hold it anymore.
"Here comes the second holy dose~!" He groaned as he let out his load, filling her up once again.
"Aaanh~ I can feel it~ I can feel your holy water is filling me up~"
