After putting in all the marbles, and playing with them a little bit more, Lisa wanted some fun.
Unfortunately, as aroused as Ty was, they couldn't get him to cum again in such short time, so they laid down, with Lisa's two tongues licking the balls and shaft of Ty's double package.
Suddenly she sits up, and started walking around the room.
"Hmmm? Lisa? What's up."
Lisa looked at Ty again. "How much can you change me? Could you like... turn me into a different creature."
Ty was a tad bemused. "Huh? Why do you ask? Of course I can turn you into something else."
Lisa looked giddy for a second, and then climbed up to Ty's face, grinning widely.
"You know what I've always wanted to be? Like, an angel, or a demon, or something fucked-up in between, could you change me to something like that?"
Lisa looked absolutely elated, while Ty ran the concept in his mind. Even if it were possible, it would require a lot of changes...
Ty leaned forward a bit, forcing Lisa to scuttle back a bit. "Alright, sit down, I'll start making the changes."
Lisa almost squeed, pushing herself off the bed and sat down on the chair, her four hands on her lap, and her face anticipatory.
Ty began looking at her. His perfect woman, whom he's now about to give her dream body...
...well, he's the one to make the changes, and he wanted to see a few traits, such as those four arms, her breasts, her pussies...
Ty "hmmm'd", and leaned forward. "Babe, could you spread your legs again, and show off your body?"
Lisa blinked, before carefully doing just that, showing off her entire frontal nudity.
Ty focused on her head, thinking about how a demonic angel, or angelic demon would look like, or...?
Lisa felt a splitting headache, and she moved some hands to her head, while she closed her eyes. "Ty? Are you giving me horns? What are you doing?"
"Just hold on for a little bit, this is gonna be over in just a second."
Lisa bit down her teeth as she felt them stretching, and after a few seconds of pure pain, she felt the world make sense again, in... double vision?
"Holy shit" "Holy shit"
She looked to the side, and saw... herself, her own head. "Wait, that's me!" "Wait, that's me!"
Her voice was doubled too, her second head speaking in synchrony.
Ty looked at her now-double head, blinking only in slight surprise as they started making out immediately.
He chuckled quietly, while his eyes moved onto other parts of the body. One half started during reddish, with horns growing from the head on that side.
He also was able to lighten her hair on the other side, while giving her body perfect abs and posture, and also removed all body hair, like a perfect doll.
Lisa stopped her self-initiated makeout for a second, and looked at Ty with both heads.
"Wait, what'd you do to me?" "Hold a moment, what did you do to me?"
She glanced again at the other head at the slight un-synchrony, and then noticed her changes, looking down her body, feeling it with all her hands.
"Holy shit!" "By the stars above!"
One head's voice was low and booming, and felt more like a growl in most senses, while the other head's voice became more ethereal, feeling almost like a whisper.
Ty chuckled. "I'm not quite done yet!"
"What are you... Ohhhh! Christ!" "What mechanisms... Oh, by the grace!"
Down below, many more changes had happened, and her demon's pussy had transformed into one with fangs on its "lips". The heavily studded tongue was currently busy licking its "chops", while drooling thick mucous juices.
The angelic pussy, on the other hand, became almost puffy, small, while from within, many satin-alike tongues emerged and started smoothly licking its edges. They had no studs, only a smooth texture that seemed to all be cut from the same ribbon.
They leaked a pool of juices, which seemed to hiss and react when coming into contact with eachother.
The demonic lower tongue retracted itself, and after some huffing and tensing from the entire body, the demon face grinned and turned to the angel head. "Looks like we still only have a single womb, now any one can get us pregnant!"
The angelic head pulled some faces, before clenching its teeth, some muffled sizzling sound emerging from their abdomen. "Do not... RUB that...!"
"Or what? You will damn me and my bloodline?!"
The angelic face theatrically "humph"'d, while both heads were pulled back to focus by a small chuckle from Ty again.
As if by sudden agreement, both heads stopped their act, and started smiling widely, and spoke in harmony. "Ty! I love this! Thank you so much!"
