Jessica does, but Jennifer is unsure...

I watch Kaitland, now a satyress and my newest worshipper, tempt and tease the two girls into joining my satyr band. I can't help but beam with pride; she is exceptionally sexy and inviting, even by my standards.
"Please," she moans, cupping her enlarged breasts and waving her tail to and fro, "say you'll join myself and Lord Pan." She extends a hand out to them.
I find it curious to see their varied reactions. Jessica looks quite ready to commit to my worship. Gently, she reaches forward and takes her friend's hand, allowing herself to be pulled up into her embrace.
"Kaitland," she whispers, and surrenders to her desires in a deep kiss. She seizes the opportunity to touch her friend's transformed body, to feel every curve and alteration, each coil of fur and the moistness of her musky crotch and milk-heavy nipples. I swear, no matter how many times I see this curiosity touch happen, it never fails to get me going.
It saddens me a bit, as you can expect, to see Jennifer edging away in a sudden bout of fear. Kaitland and Jessica break their kiss, as the satyress guides her friend slowly down into my embrace.
"Jennifer," I speak in my softest voice, distracted barely by the tongue of her friend brushing against my dark nipple. "Why do you fear? I have not come to do you harm."
Still, she cowered. "I...I don't know...I just...never expected..."
"To have someone really appear to grant your wish?" Slowly, timidly, she nods.
"Oh, Jenny," Kaitland sighs, crouching down upon her goatish haunches but not yet approaching closer. "It's a wonderful feeling being a satyress! I'm happier now than I ever thought I could be, lurking in gloom. I feel it, true immortality, and true pleasure, and I want to share it with you."
Jessica slinks down to greet my penis, eagerly fondling my heavy testicles as her tongue and lips glide along my shaft, working sheath to tip and back again. I brush her hair tenderly as she looks toward me, closing her eyes as she takes the first plunge.
"I am not a god of anger or malice, Jennifer," I groan through Jessica's ministrations. "I do not take the unwilling, and I believe in mutual pleasure." As I speak, Jessica receives her first taste of my maleness, and her oral eagerness accelerates in kind. Kaitland busies herself with removing her willing friend's clothing, "accidentally" brushing against her bountiful mammaries to Jessica's squealing delight.
Jennifer looks upon the scene with cautious interest. "I...I want to...but to give up...being human...it's a big thing to do." She clutches and tugs at her clothing as she talks, torn between her human mores and her inhuman desires. I understand it well; I've seen it countless times before.
I look Jennifer deep in the eyes. "I will do nothing to you without your permission. Ever." All rumors and slander aside, I've never broken that promise, not in all the millennia I've existed or to any of those I have taken as lovers or worshippers. I won't start now.
Jessica looks up momentarily from her sucking, to wink at Jennifer. "You have no idea how good this feels, Jen. And I'm not even done yet." Without a word from me, her libido takes over once more, and she resumes her pleasure. I have the feeling she would have the same opinion, even without the influence of my first dose.
Almost as soon as I think that, my semen floods her mouth. She swallows every torrent, deep-throating me as she does, and I realize that her throat has been altered by my seed to fully take in a satyr's phallus.
Across from us, I see that Kaitland has crouched behind Jessica, with her hands resting on her shoulders in a sensual massage. She whispers a request into Jennifer's ear, coupled with a lick of her tongue and a gentle exhalation. The human nods wearily, guiding my charge's hands inside her leather shirt and pants.
Jessica rises from my crotch to my mouth, kissing me with a combination of her slaiva and my seed. Oh, but this is a feisty one!
"Lord Pan," she moans, "I am yours forever." She grinds her slit along my shaft, working all the way along the cleft of her ass and down again before grasping my thick shoulders and urging me upwards.
"I want you to transform me, Lord Pan, to remake me in your image." She turns her body over, resting on her hands and knees. "Mount me, and make me a satyress!"
I need no further prompting, and grip her shoulders as I drive my cock deep inside her with a wild bellow. Jessica gasps in mixed agony and ecstasy at the ferocity of my rutting, ebbed away by the twin euphoria of sex and change. She moans and huffs as her skin grown golden and her hair flows into a chestnut curly mane, across my hands and down to her swelling globes.
Through the haze, I watch Kaitland bring her mouth to Jennifer's clit. The human is bare to the world, her eyes fluttering in pure pleasure as she presses her crotch tightly against her changed friend's mouth.
I smile as the human moans in delight, fondling one of her breasts and one of her partner's. She has potential yet, I think, even as Jessica's burgeoning horns frame my view.
Her ears, already pointing and furry as my own, twitch as she grunts in time with my own outbursts. She drives her rump hard against me with her sixth orgasm, and as I caress her stocky legs and rising ankles, I can no longer tell by mere touch where my fur ends and hers begins.
"It is time, Jessica," I grunt, watching her dainty blossoming tail and fusing toes. "Say it!"
She drives her hooves hard into the ground, splashing dirt behind her. "I'm...a...SATYRESS!"
I explode within her, sealing her initiation. "Yes, my dear. Forever."
The beautiful creature slowly separates herself from me, looking up through her hazel eyes with boundless admiration. Across from us, Jennifer screams her own climax, gushing into the greedy mouth of the satyress crouched before her. Kaitland dutifully licks her pubic hair clean, a touch I can appreciate on so many levels.
I bid my satyress followers to me, and they take a place at my sides, touching me as freely as I do them. Jennifer looks wearily up through her afterglow, as I extend my hand to her in invitation.
