Mutate her body into a breeding ground...

Aurora lurched as the seed began to change her, her stomach visibly shaking. Her eyes filled with tears as her body began to war with itself, something terrible dividing her stomach. It began to burn.

A strange tooth-like pattern formed beneath the skin of her swollen abdomen, a new mouth, forming in cartilage in her mutating flesh. Her skin began to pull against it, now itching, as she felt her breathing become moaning, and screaming. The seed of the alien seemed to get hotter, roasting the inside of her flesh, triggering strange growing pains. Her breasts began to bloat, her nipples lengthened, her areola expanded.

At last the teeth within her abdomen began to protrude through her skin, a glistening white. She bucked, pulling against the resin, not sure what to do but unable to help herself. Finally, the teeth were free. They opened wide, exposing a strange alien vagina into foreign anatomy, screaming in the process. She felt a new womb form in her tummy, much larger than her natural one. She felt something move that was not her.

Her breasts began to ache with a pain that could bring her to her knees. The nipples divided before her eyes, then the areola, then the breasts themselves, giving her four massive tits. She felt them actively and aggressively produce milk. Within her tummy, several infant aliens began to stir, as they grew.

She collapsed, and breathed hard. Her fate was sealed.
