Then the tail moved.
She didn't see it coming.
She felt it.
The specific, 'wrong,' unexpected, impossible sensation of something entering her from below — smooth, warm, shaped differently than fingers, different than his cock — pressing against her entrance and 'pushing in' with the flat, insistent determination of something that had been waiting patiently for its turn.
The tail.
The incubus tail — spade-tipped, narrower than his cock but equipped with the specific, infernal design of something built to find nerve endings and 'press' — entering her stretched, creampied, soaked pussy with the smooth, comprehensive slide of something built for exactly this.
And then it 'vibrated.'
She hit the ceiling.
The sound she made was not a moan.
It was not a scream.
It was the compressed, muffled, throat-deep sound of a woman who has just received two simultaneous inputs she had no framework for and whose body has responded by doing everything at once.
"'MMMPH~!! HNGHH~!! HIIEEK~!!'"
