As Jenny placed her hand on Jeff's shoulder, she thought to herself, "I want two heads." Responding to her desire, the pendant began to glow almost imperceptibly, and she felt a strange power flow through her body and down her arm. In a matter of seconds, Jeff was seemingly sucked into Jenny's body, scarcely giving him time to react or even yelp. For a brief moment, the ruby on the pendant seemed to gleam a bit brighter before settling down.
Then, the changes began. Jenny gasped as she began to feel a tugging sensation on her head and neck, simultaneously pulling to the left and right. Gradually it intensified, but it wasn't painful, just foreign. A moment later, it seemed as if her field of view expanded sideways as new eyes formed. However, her view then seemed to gain more depth, and it felt like her way of breathing was changing inexplicably as well. Finally, the sensations came to an end, and Jenny impulsively ran to the nearest mirror to see what the end result was.
Shocked by what she saw, the young woman gasped in triplicate. Staring back at her were not two heads, but three, all perfectly identical down to the mole below her left eye. Cautiously, she raised her hand to gently touch her right head's cheek, just to make sure it was real. A moment later, all three of her faces broke out into wide grins.
"""This is so cool!""" She exclaimed with all three heads at once. Experimentally, she tried having each head turn a different direction, and became slightly disoriented from the way her perception diverged.
"This is going-" her left head started.
"-to take some-" her right head continued.
"-getting used to," Jenny's original head finished.
Suddenly, she remembered her boyfriend. "Jeff! Can you hear me?" She asked with her middle head, uncertain how the pendant worked.
*Yeah, can you hear me?* Jeff's disembodied voice echoed in his girlfriend's mind.
"Yes, oh thank goodness," Jenny replied with relief. Speaking with a different head, she added, "Though it seems I only hear you in my mind... Can you talk with either of my new heads?"
*No, but I can see, hear and feel with them,* Jeff answered mentally. *I was actually trying to talk this whole time, but it seemed like you couldn't hear me.*
""Oh weird,"" she replied with her left and middle heads in sync before her right head continued, "Maybe I have to focus to hear what you are thinking."
*Possibly...* came the response, followed by, *What's the deal with the third head, anyway? I though you were only turning me into one more.*
Chuckling in awkward triplicate, Jenny replied, "I'm not sure myself, maybe it has to do with my thoughts while absorbing you? I didn't really have a mental image and just thought to myself, 'I want two heads'."
*Perhaps the pendant interpreted that as you wanting to turn me into two EXTRA heads?* Jeff suggested.
Shrugging her now-wider shoulders (which grew apart to give her space for three heads), Jenny said, "Your guess is as good as mine."
After a pause, Jeff communicated, *So now what?*
"Well..." his girlfriend began with her middle head before her side heads finished in stereo, ""There is something I wanted to try."" Turning her middle and right heads to face each other, she brought their lips together and began kissing herself. It was a bit strange at first, feeling both sides of the kiss at once, but she quickly grew more into it. Her tongues took turns sliding into the opposite mouths, the kiss gradually gaining intensity.
*Wow, narcissistic much?* Jeff's voiced teased inside her heads.
*Oh, shut up. Don't pretend you aren't enjoying it,* she mentally replied, sarcastically.
*You got me there, haha,* her boyfriend chuckled back.
Breaking the kiss, Jenny panted for air with both heads before turning her middle head to face her left one instead. Starting another passionate kiss, she used both tongues to battle for dominance as the flexible appendages explored her mouths. Getting more and more turned on, Jenny began to massage her left tit while her right hand slid down to start fingering her moist pussy. With nothing else to do, she turned her right head and began licking her middle neck.
Onwards this continued for several minutes until Jenny's masturbation brought her to orgasm, all three of her voices crying out in harmony. As she was coming down from her high, Jeff mentally commented, *You were right... I think I did enjoy that almost as much as you did.*
