"At first I thought you were just some creep, but because of what you've done for me I'm so happy that I just can't help but give you the greatest reward I can think of..."
Jenny struts forward and places her hand on the crotch of Kyle's jeans as his erection makes itself prominent.
A mix of excitement and worry crosses his face "W-wait I don't think I'm-"
A faint glow flashes from Jenny's eyes and in an instant Kyle cums in his pants.
"Oh sorry, did you think I was going to jerk you off? maybe more? Haha don't worry, what I've got in store for you is even better."
While he continues to bask in the pleasure, Jenny snaps her fingers and all his clothes disappear. She lightly places her hand on the tip of his leaking dick and begins gently pushing it. In response his dick begins to shrink until it's just a nub at the base of his crotch, she then lightly pushes his testicles into his body and begins working his insides to form a fully functioning vagina.
"You're probably overloaded by the pleasure right now, but just a quick peek into your mind is telling me you're loving this."
With that done, she glides her hands over and around his body to sculpt it into a more feminine shape, taking some extra time groping his growing ass before moving onto his face. In just a few moments he looks identical to Jenny, except for one part.
She takes a moment to snap "him" out of his trance . "I want you to feel this one specifically."
She begins kneading his chest as it quickly grows into a bountiful pair of breasts, seemingly entranced by her own work she begins to suck on them while making them grow even more.
by the time she realizes what she's doing, "his" breasts are twice as large as hers, and "he's" broken down into a cumming mess from the stimulation.
"Whoops, back to earth bucko" she says snapping her fingers.
Kyle returns from "his" daze, Jenny quickly materializes a mirror to show her identical yet hypersexualized twin.
"Holy shit... I- Thank you so much my goddess." she says while attempting to bow, yet looking more like someone trying to balance on a yoga ball.
Jenny lifts her chin.
"It's not over yet, sis."
Before Kylie reacts Jenny begins vigorously making out with her, all the while a glow wells up throughout Jenny and pours into her.
After 5 minutes straight of making out Jenny finally lets her breathe.
"What did you do to me...?"
with a smug expression Jenny proudly states "I gave you a similar power, now we're twin goddesses! I thought it would start getting boring if I didn't have anyone to relate to after this; of course, I'm still superior so don't get any funny ideas."
