Erin from attack on titan (Patreon)

"Oh-oh-oh-oh! Yeah, bitch! Don't change the rhythm! Keep me high there ..." a loud hoarse voice filled the entire room of the brothel in Sina district of Mitras where live all the nobility of the walls, men and women. A fat man laying on the bed while being ridden by a sexy naked girl with a beautiful body. Her boobs bounced up and down, her firm but succulent ass kept hitting the thighs of the guy she was jumping on.

Erin was born in an ordinary working class family in Shiganshina District that has now been destroyed by two titans that suddenly appeared several years ago - an armored one and a Colossus. As many people from the district, she was taken in the walls and thanks to her sexy young body, she was hired as a maid for the Palace of nobles.

True, she only found out later that her responsibilities included more than just cleaning floors and cooking meals for the owners. Much more often was used to entertain guests of the masters, noble guests. The nobles don't like dirty and ugly servants and so she was dressed up and showed to their important person. But despite this, it was still a good fate for such a poor girl, who had already adapted to this in half a year.

But for some reason, right now, during yet another wild ride on a client, her face changed dramatically. She suddenly stopped moaning, stopped showing signs of pleasure and looked down at him completely shocked with wide-open green eyes.

"Why are you stopping ..." - fat man barely getting the word out of him. He was already close when she froze.

"WHAT?!!" Erin shouted. Her heart sank to the floor, "What happened? Why am I ... BOOBS!?!" She grabbed the boobs hanging in front of the man's eyes and immediately exclaimed in shock again when she felt hard dick sticking in her pussy.

"Shit, girl, do you really have no idea that men do what's between your legs ..." - but his words were interrupted by a deaf scream and he looked surprised into her face.

In the same second, her pussy squeezed the cock and his seed filled her uterus, then spilt back out as Erin's muscles finally let go.

She didn't know yet that she was no longer Eren but Erin Jaeger now and was no longer in boot camp preparing for life as a soldier, but in a brothel. Because to Titan the progenitor, who saw the future and in order to avoid destruction of humanity and the extinction of all the humans, decided to change history itself and changed everything so that Eren wouldn't get the titan powers and thus wouldn't turn into a suicidal monster who would ruin himself and his friends in the name of his idea and hatred towards people.
