What's next?

All in

Jason looked at the hopeless redhead. "Emilia... You're a hucow now. And without a baby you don't produce enough milk. I am here to fix that". She looks down a moos sadly. Jason doesn't care and sits down on one of the overturned milk pales. He takes up the book again.

New Rule: When a hucow is first bound, she permanently grows small cow horns and her tits swell with milk. Patches in the pattern of a cow will appear all over her body matching the color of her hair. A hucow is impregnated after a male cums inside of her.

Emilia's eyes are wide as her breasts start swelling. The patches show up on her skin and two cute horns come out just above her temples. Jason smirks and pulls out his phone to do a quick search. After all, a hucow deserves to be broken in by a hubull cock, whatever that is. "Holy hell..." Jason muttered "Thats... a bit much. gonna settle with less."

Old Rule: I, the author of this rule, possess a sixteen inch dick when erect.

New Rule: Hucows wombs and vaginas expand to fit the cock inside of them.

Feeling his erection enlarge Jason quickly removes his pants. Emilia follows his massive member with her eyes as she cannot move her head. He steps out of view behind her and appreciates how her pussy is at perfect fucking height. Slowly, he pushes his cock into her exposed flower as she lets out another moo. Picking up rhythm Jason pumps in and out of her, listening to her moo in protest and watching her tits sway from the weight of the milk and the motion. He feels the back of her womb stretching back and forth as he fucks her furiously. "My god she is tight" He grunts, pumping as hard and fast as he can. The feeling of his cock twitching is a tell tale sign he's ready to cum. "Here's to your motherhood sow!" He dumps his load into her as she moos, orgasming with him. Stepping back he slowly unsheaths his cock from her, cum dripping out of the gaping hole.
