The Body Modifier gets Modified

"Potion 8 has very interesting effects on the injector tentacles." Citranas says as you grope Asriana with a set of long tongue-like tendrils oozing blue slime. Like your old tongue, you can now taste the sweat and milk coating the elf, yet instead of secreting saliva like a normal human, your new tongue endlessly secretes your lactation ****. Soon, her chest reaches the size of watermelons, forcing you to grab ahold of her limbs to support her as her nipples become inverted. Your body moves by instinct, sending a pair of sucker tentacles to latch onto her breasts and slurp up the overflowing milk spewing out from them.

"Don't be impatient Verdi." Citranas says playfully, referring to you with your new pet name as she she removes a syringe from her coat and jabs it into you. Instantly, you feel your body shift as the suckers begin shifting about. The large cups at the end that attach to your targets breasts are absorbed into your tentacle as you feel yourself become more hollow. Soon, thousands of tiny holes smaller than a pinprick appear on your new tentacle, sucking up the air around them as they position themselves above Asriana's chest. Without hesitation, the tentacles shoot forward, penetrating her breasts as they continue to swell even with your incursion. You taste milk even richer than before as you send more tentacles to Asriana's lower lips, penetrating her as you did before.

"Test subject's mammary glands gain the ability to be penetrated. Fat content increases by 300%. As for sensitivity..." Citranas says while grabbing Asriana's chest, earning a deep moan in response. "Acceptable." She writes as you wrap a tentacle around her arm. Grinning, she lets you grab her and tear her clothes away, exposing her nude body once more. Her erect cock flopped out, slapping her in the face as you lather your new secretions onto her chest to begin fucking her nipples like you were doing to Asriana and the rest of the elves. Though the sight was stimulating and the sensation of entering breasts was comparable to any of their other holes, you couldn't help but feel worried for your future.

It had been weeks since you had stolen her virginity, and everyday you wish you never exposed her to the world of sexual delights. Mixing an autistic attention to detail, years of repressed sexual desire, and a god's blessing in alchemy meant that you had the most depraved human in existence experimenting on how to make you even more perverse. Your already existing tentacles were modified to have newer and stranger uses thanks to her **** while your already existing mutagens had their potency enhanced several thousand fold. Rather than taking the mutagens from your organ cavities and modifying them, Citranas opted to alter your very biology to create more potent chemicals.

Your original lactation potion would usually get a few dribbles of milk out if you squeezed and sucked their breasts and wore off after a few days. The new version caused women to incessantly spew milk like a broken faucet, spraying everything in their vicinity like a debauched sprinkler for a week straight. Your new cock growth potion lasted longer, was more potent, and had the side effect of stubbing those new cocks with thick bumps to stimulate partners further. Even your tentacles were not spared from the mad alchemist's debauchery, with your tendrils altered to better pleasure your partners. You now had new tongue tentacles specialized for tasting your prey and spraying your newly enhanced ****, spongey tendrils that absorbed milk while you fucked nipples, and even a new sucker tentacle for stimulating partners with oversized cocks too large for humans. They'd done all manner of things to you, and had no intentions of stopping anytime soon. The worst part was that playing dumb no longer worked, Citranas' home cooked aphrodisiac capable of effecting even a sentient monster like you into mindlessly breeding anything in sight. A part of you said this was just desserts for injecting Asriana's comrades with an aphrodisiac, you only did that once. This mad alchemist had been pumping you up with gallons of the stuff for weeks! The only reason you were still somewhat sane was because you had 6 other monster cores still rational enough to think. It's this little event that you learn more about your own body.

While your main body's mind was still rational, your **** up second body was completely feral, moving on pure instinct thanks to the aphrodisiac. You could still evoke skills on your second body, but they were significantly less effective than before. As far as you could tell, you were Citranas' sex **** for the foreseen future. In terms of bad endings, spending the rest of your life having sex with a hot mage and 4 elves in a pocket dimension wasn't that bad of a fate.
