Save "Fantastic Proportions" for a future breast-expansion gender-swap one-off story or series project (perhaps with the protagonist ultimately being transformed into a human cow for a milking and breeding farm)!!
Alison is quite small, 5'1" on a good day, and quite thin except for a few key areas. I'd guess around a US size 0 to 2. She'd probably have trouble shopping off the rack for anything form-fitting due to her rather fantastic proportions.
I'd like to second BMO's comment wishing that this won't be a one-off series but that there'll be more issues to come once this introductory one concludes!
As for the silence collar, as much as I love the novelty of it for this sequence of the story, now that our protagonist's hope for rescue has been completely dashed by this demon's quick reflexes and sorcery, and therefore the need for the gimmick having passed, I'd like for that spell to soon be lifted just in time for our protagonist to scream -- not out to their would-be rescuers (thoughts of them and their potential to help them out of their current predicament having quickly escaped their mind, their complete attention now absorbed by what their tormentor is doing to them and how their newly-femme body is reacting to the sensation of having their virgin pussy penetrated by such a long and girthy cock and fucked so savagely) but from the throes of sexual ecstasy!!
Something tells me that Allison doesn't really want him to stop teasing her and mussing-up her hair (based upon her conscious or unconscious body language cues and especially her full-on eye-contact)!
Now, as her pre-forced transition male self, Allison was no pip squeak -- a respectably-built merc who could handle himself in most conflict situations, but even with that extra body mass lost to that aforementioned transition (some fraction of which gained back in the shaping of Allison's ultra-feminine figure as showcased by those top-heavy tatas, that tiny waist that slopes out to those wide hips, and that comely booty she now sports) he'd still have been well-outsized when compared to the physiques of the male demons (like Torin) of this otherworldly realm.
In her pre-transition form, Allison might've had a slim chance regarding any escape attempt, but there'd be absolutely no hope for her in this one, and I think that she'd quickly forget why she was there in the first place and become overwhelmed by newfound feminine desire (perhaps influenced by that initiate's collar she's wearing) to grapple with this male demon in a much different way than her former male self would have!!
One for each day of the week -- with the seventh one being Allison naked, like in the sixth panel, but with her hands not holding her boobs, freeing them to be in full view in all their voluptuous glory and doing an exaggeratedly boisterous t'dah pose with either pasties or tit clamps over nipples, Disney princess-style tiara on her head and her hair done-up with extra-girly Lolita-esque pig tails on either side of her head, blowing a big bubble gum bubble with her eyes crossed like the bimbo airhead she's become!!
Something tells me that she's gonna be like "Coulda fooled me! Which one of us does it look like is packing the big meat and which one has the virgin tight little snatch that's fixen to get deflowered?!?!"
I like it a lot. It's very good for a first time experience of a story.
However, I do hope you will also make individual pages available. I can't say I like the idea of clicking through comic pages to find The Page that I'm looking for as material.
Q: What collars do you plan on putting on the Demonic Twins Melody takes on as her first Dominatrix assignment? I still think she's biting off more than she can chew frankly. (Which might be beneficial to some hilarity later on.) But even one as "over?" confident as Melody will want some anti-strength or magic-hindering enchantment to keep the twins from overpowering her. She's clearly mostly human after all. And the twins are succubus's who've probably got internalized magic behind them. A dangerous proposition without countermeasures.
A: Given the twins' minor shape shifting ability and demonic sex drive, any sort of lust enhancement would be counter-productive in terms of controlling them. Melody will probably elect to use a particular mix of pain and dissociation known as a command collar. When the subject is given an order in a particular commanding tone, the collar activates. If the subject does not comply they will begin to feel uncomfortable. Anxiety and guilt rise and the master's command weighs down as the most important thing in the subject's mind, like a long neglected responsibility. If they continue to resist, a mild hypnotic dissociation begins to take hold. If they continue to resust, the subject may soon find that they have carried out their mistress's orders without realizing it.
Of course this is just a insurance measure. And it's a fine line between getting what you want out of a sub and violating trust. Part of being a mistress making your sub realize they want to obey, and to make them play your games rather than fight the referee.
Q: Curious, is the anti-pregnancy enchantment the only one on Alison? I'm sure the cuffs she used to wear where a form of restraint early on. But I'd imagine they'd want a way to reel her in if necessary. Then again, she is physically weak. So outside of leveraging her purpose or some slick trickery, she's not going to get out of a fortress full of demonic soldiers. (And frankly, she's just is not clever enough to pull off such deception. Stupid? no. But not brilliant either.)
A: Alison doesn't really need to be broken, she just needs a small amount of force applied - enough for her to use as an excuse to herself. Just a little push and she'll fall right where she needs to be, and that push is best applied the old fashioned way. Anything more would be at best a waste and at worst might upset her natural proclivities.
