Watch her grow

Kazex stands proudly in front of the elf, naked, with his cock hanging between his legs. The young woman getting back to her senses opens her eyes wide in fear.

"Calls of the light ! W-What's... !!" She says in panic before realizing she's shackled to the wall.

At that realization and noticing the absence of clothes, she starts to panic even more. But already, her face and crotch slowly turn red from the warmth feeling that comes with arousal. The young elf had the usual body of the species, slender and slightly muscular body, very small breasts, pretty much no ass, and hairless under the neck. But as she is starting to breath heavily, mumbling words of confusion, her whole body starts to expand.

Her already discreet muscles quickly disappears under a layer of fat, her breasts inflates like crazy into soft buns with pointy nipples and her small areolae grow accordingly. Her ass also grow bigger and larger as her hips widen to be more suitable to bear children. Her thighs become twice their previous size and her pussy turns more plump with, now, a constant drooling of lubricating love juices. The changes slowly come to an halt as she has her breasts as big as her head and a plump figure with a soft belly. It would be hard to guess she's an elf if you don't look at her face.

Extremely aroused, she tries to rub her thighs together in a vain hope of releasing some tension. But the shackles forbid her to do so.

"You seem to be in need of a good cock." Kazex tells her with a big smile.

"N-No... please... Mmmgnh... I need... I don't..." She says in moans, sweating from her carnal heat.

"Are you sure ?" The goblin asks, rubbing his cock against her engorged clit popping out red and hard.

"Aaanh... I won't... Gnnnh... fuuu... Yes... please... do it !!" She finally admits.

Happy that his potion works like a charm, he pushes his cock into the lubricated pussy of the chubby elf. His hands squeeze and knead her big fat tits, which makes her loudly moan of pleasure. The goblin is really enjoying the body of a good goblin breeder, she'll surely bring a lot of healthy babies.

"You like it ? Being a goblin bitch ?" He asks.

"You... Aannh !! You'll pay... Aaanh !! for this !" She answers, with all her energy.

Kazex bite her tits with his pointed teeth, not too much, just enough to be painful, and the elf scream in pain and pleasure. The sensation seems to have pushed her over the edge as she shake and become tense. She gets her first orgasm in a long cry out of pleasure.

"What a slut, coming like that, are you a masochiste ?" He asks her.

"Fuu... you... I... Aaannh !! You !!" She mumbles, unable to resolve herself in swearing.

Elfs don't swears, they find it deeply inelegant. But already she came close to break the cultural tradition. Kazex can't help at the idea of corrupting that uptight bitch. Motivated, he goes harder on her, pushing back and forth his cock in her drooling pussy.

"Oooh... please... stop... I'm... Aaanh !! I'm going to... AAnnhh !!! coooOoome... !!!" She moans.

This time both of them come and Kazex fill her womb with huge loads of fertile cum. When he pulls out, some of it even flows out like a milky river.

"You... ass..." The elf mumbles, swearing for the first time in her life.

Now that she's calmed down, she finally notices how her body had changed. Her reaction isn't too **** as she is still exhausted.

"What... ? What happened to my body !! My beautiful body !!" She shouts.

"I made it better for bearing my children !" Kazex explains to her.

"You-You can't impregnate me ! We're... We're not compatible !!" She says, trying to reassure herself.

"Not anymore, bitch. You're now a perfect goblin breeder. I'll even call you Gobitch ! Ahah !!"

"You little... I'll... I'll... !!" She says red from anger.

"You little what ? Say it ?" Kazex orders her, amused.

Saying that, he rubs her clit which makes her uncontrollably moan.

"You little shit !!! There I said it !! Fuck !! I... hate you !! I hate you... Mmmh..." She starts shouting before it turns into moaning again.

The goblins is enjoying the results and is rock hard again. Goblins are made for sex and reproduction, and now she is too...
