It seems that my previous synopsis was not very clear, so here is the clarification:
An ordinary man dies and has the opportunity to be reincarnated, but after making a mistake in front of the goddess or basically desecrating her in his thoughts, he is punished by being reborn as a woman. 
But later, he discovers a method to temporarily recover his male body (legacy of lust). 
However, his endless desire will be the least of his problems. 
This world is nothing like the fantasy he dreamed.

“As for genres, there's a little bit of everything: Harem, Romance, Comedy, Yandere, Yuri, MILFs, Lolis, Elves, woman-beast, Demons, Dragons, Gigantes, Priestesses, Androids, incest, Group Action, Futa, a little bit of SM, and much more. If it captures your interest, great!!!”.

Now, drawn into a battle for power where even the gods take sides, he fights not only for revenge, survival, and ambition, but also to protect those he holds dear—and everything he has built. In this second life, forged by sacrifices beyond his comprehension, he will carve his own path… no matter the cost.

I roughly grabbed her hips and if more, I made a strong thrust that made me reach deep inside her in one move


Not only that my member started to regain its standard girth and expand Astrid's insides, which from now on would adapt to me.


She seemed to be losing her wits a bit, not only because of my abrupt pumping and expansion but because, notice that, indeed, she is very sensitive and it seemed to stimulate her a lot.


It seems that she was overwhelmed by the sudden combo of intense sensations, as she started to act frantically, as she was leaning on her desk, her agitation knocked over some things , such as papers, books documents and so on making a mess in the surroundings.


She was reacting more intensely than I thought to the point that I got worried, a little, of how frantic she became, it looked like she was about to break her desk which in fact was made of a very good wood, but just at that moment she....
