Spanner is now a girl

"What is happening?"

The image of Spanner was distorted like a broken TV screen. A sharp pain cut through his body as if an invisible surgeon was continuously slicing him apart and then reattaching him back. He kneeled on the ground and screamed, but no sound could be heard.

The pain disappeared as quickly as it appeared. Spanner looked down, only to discover a shocking truth.

"He" has become a "she".

Spanner groped her now-big-and-round breasts as if checking whether she was dreaming or not. Her helmet had disappeared, revealing the face of a 19-year-old woman. Her eyes were green like Ben's, but her hair was darker.

The shock prevented her from noticing that the mating on the bed was over. Ben, still in his Blitzwolfer form, pulled his cock out of Kai's vagina and slowly approached his new prey. Only after his shadow looming over her did she realize it.

"Ben?" she called his name tentatively.

There was no recognition, emotion, feeling, or intelligence in Ben's eyes. He did not see her, all he saw was a fertile female and his instinct told him to breed her.

Spanner tried to run, but Ben was faster. With a swift movement, he reached out and grabbed her ankle, pulling her back. Then he turned her over, ripping her clothes, and spread her legs.

Seeing the still-dripping cock slowly go toward the rift between her legs, Spanner knew exactly what fate was waiting for her. She began to struggle under him until he growled and bared his teeth, wordlessly warning her to stop resisting and submit. She obeyed but still cried and begged:

"Ben, please stop, I don't want to do this."

Sensing her submission, he sensually rubbed his cock against her labia in an effort to further relax and stretch her opening. She screamed in pain as his initial thrust broke her hymen. She defensively reached him to keep him from going in further, but he grabbed her wrists and pinned her hand to the ground.

With no obstacle on the way, he began to thrust in and out of her like a piston. His movement was hard and ruthless, and Spanner could feel his cock go deeper inside her each time he thrust in. She shouted, "Somebody, help me!", but the only one who could hear her was Kai, who was still fainting from the intense breeding session just now. As time passed, her pleas slowly became moanings, which inflamed the lust of her mate more.

Ben released her arms but still held her in place. He continued to push into her, trying to stop her pussy wall from closing in while adjusting the angle of his cock. It was as if he wanted to lead that thing to a certain place.

Suddenly, Ben stopped moving, then Spanner felt his cock penetrating through her cervix. Her body stiffened. She had just become female, so it's obvious that she wasn't on any birth control. She didn't even know her own menstruation cycle! Being creampied might not result in pregnancy, but she didn't dare to bet.

"Dad, no! Please, wait, wait, wait!" She screamed at him.

But it's already too late. Ben howled while he held her ankles steady and his cock began to pulse. Then he pumped what seemed like impossible amounts of warm cum inside her. She let out a scream mixed between pleasure and fear. As far as she knew, there might be millions of potent sperm swimming inside her right now, ready to fertilize any egg they encountered.

Unlike before, he didn't pull out. Ben transformed back to human form and fell into an exhausted sleep with his cock faintly pulsing and still buried snugly inside her pussy.
