Jeff reached out to stroke the tip of the snakes head, and amazingly, the snake nuzzled his hand as it approached, giving a Jeff a shiver as he felt the pleasure go all the way down the snake's spine.
The snake's apparent hole gaped, brining to mind that it was quite larger that it should be on a snake; but the flushed feeling of the apparent vagina brought need to Jeff as he used both his hands to stroke the snake writhing in pleasure in front of him.
He brought one hand down to his partner's snatch, poking one finger inside; causing him to spasm just from that, almost too much to handle. The seemed more used to it, as it seemed just find twirling itself down to face its own snatch as Jeff lost himself. It let out its tongue and drew its tongue down the apparent labia pushing Jeff further into whatever trance he'd entered.
Jeff absent-mindedly continued to stroke the maiden snake, the snake coiling around his arms with the slack in its body as it did so; drawing pleasure out of as much of its length as it could. Drawing him deeper and deeper into this hypnotic sex act; until Jeff could barely feel much else of his body save the snake, as the rest of his body became numb from the pleasure, leaving nothing but the snake.
At this point it was almost as if he was the snake, thinking of himself as it, beginning to see her own sex from the snakes perspective, licking at her own womanhood, far more human than it should be on a snake, and far deeper. She began to wonder if she could fit her own head inside herself. Soon enough her lips parted, as she made her way inside herself, drawing it out slowly to pull as much of herself inside as she could before it reached its peak, and just as the end of her tail was just about the only part of her that hadn't entered her vagina, she sped up, pushing her coiling around herself to its peak as she felt something building throughout her entire body, flowing out from her vagina.
Suddenly she felt a torrent of cum shoot from her mouth, filling the womb with her; and so she slowly began to slip out of her womb, taking several minutes to slip out.
Once Jeff's sense seemed to return to Jeff's body, they could feel both bodies, control both bodies as they flexed their hands and coiled around a bit, see through both eyes as they swivelled their heads to see the entire room at once... But there was a problem.
Jeff still felt as if "her" consciousness was still housed in the snake's body, as if her snake body was now the real Jeff, and their human one, even the head, just felt like an extension of herself.
Perhaps it was just that she felt that way because her "Snake dick" was still so sensitive after sex that it drowned out the human body in comparison; like how you have more nerves in your face so you feel more associated with it... Or maybe she'd screwed up her mind by doing this, had she fundamentally screwed up her own brain?
… Then again, if she had, she could just change it back with the Chonivac… But did she really want to? Being a girl snake dick felt amazing, and if she'd indeed just cummed into herself, she may well be a parent to a clutch of eggs.
She shook her snake head, one thing at a time... She didn't know if she truly wanted to think of herself as a girl yet, yet alone a mother... And yet here she was, thinking of herself as a female.
