"Well I can do that. Because I'm a vagina Jon, our vagina, now i know because my lips feel vertical, i'm covered in a beard, i can see i'm inside a woman's boxer, and i'm tasting and smelling your crotch sweat, Joni babe!"
Karyn patiently listed her current conditions, with a calm vitriol that was reflected in a furious effort that physically moved her reduced anatomy, reeling from the betrayal of her best friend for the perverted amusement of their worst enemy.
Jon locked down at the clothed sentient organ and shocked at the feelings coming from there pleaded "Karyn, Karyn! i am sorry, i will fix this, i will ask Sarah and choose other words and and, i..."
"Shut up and listen to me, ok, don't talk at all!" Karyn couldn't care, pausing for breath to voice a coherent accusation instead of any of the rapid string of curses flooding her mind "What was that about, you and i, being one being, what were you thinking!?"
Jon could only stare guilty with his mouth open at their new pussy, were Karyn voice was coming, not an auditory voice, but both could sense the labial muscles moving enough as if to mimic a vocal function, provoking an arousal on their fused body.
"Does this excite you, me losing any manner of autonomy to be your horny appendage, do I'm turning you right now?"
An arousal that coincidentally emphasized the increased heat of Karyn's anger between each exited breath.
"Hey! don't you wanna see me now? and face this fantasy of yours!?"
Breaths now synchronized with Jon diminished resolve at this furious stimulation, expressed trough his hand rubbing their shared groin.
"You really like me like this do you! i'm feeling the heat down here, its a sauna in your pervert pants, will you zip down and trow your belt right now, do it, i can use the fresh air, c'mon !!!" Karyn commanded.
It was to much for Jon, dropped on his knees, shared a joyful relief with Karyn release from her humid prison, as they both marveled at the sight of each other at the start of their impromptu masturbation session, all in the presence of the smiling Sarah, omnipotent cheerleader, letting out brief laughs between pleasant touches on herself and sips from a special events wine forbidden to her by her mother.
"Well, this certainly is the start of something special" Sarah mused where to take things from here on out.
