After the blowjob, Miranda turned back to her actual female self, and she was really happy about it. She told Alex that it was horrible to be a guy. Alex was really disappointed to hear her say that, he had hoped the experience would have opened up his girlfriends mind a bit, apparently it didn't...
Thing is, Alex did like Miranda but she was so... vanilla. Sure, she was very pretty but she was as standard a heterosexual, cis woman as they come...so traditional, so boring! Not even a bit bi curious... Alex was satisfied with her for a couple of years, sure, but now he wanted a more modern, exciting and adventurous love partner! How cool would it be if she were a bisexual, open minded transman instead? Alex decided he could try to talk to her about this, and so he did. A little bit at a time, and very cautiously, Alex began exposing his girlfriend Miranda to the world of gender diversity, educating her on the complex subject. Time passed, and Miranda actually made lots of mental progress, Alex even took her to a few gay prides, and had her meet with a couple of trans people. Miranda listened to stories of their transition and the journey of finding your happiness by finding the real you.
After all of the constant and intense exposure to all things LGBT, Miranda was finally ready...she gave in to all that conditioning and one day she tells Alex she wants to be someone different! Alex was beside himself with joy, and that night he made love to Miranda the straight woman for the last time......
Miranda's journey of changing began the very next day. First of all, she/her got corrected to he/him, since Miranda's gender identity is now male. "She" started the gender reassignment process, and after a lot of hormone therapy, surgery, testosterone, a perfect phalloplasty, heavy weight lifting, even facial plastic surgery and a headahave, since HE wanted to look like a completely different person... Miranda became Declan, a bisexual and athletic transman... Declan legally changed his identity and soon he and Alex got married, both of them looked dashing in tuxedos, black for Alex and white for Declan.
The sex between them was always fulfilling and they were as happy as could be. Declan quit Miranda's old job as a waitress and entered the police academy. He also became a wild LGBT activist.
Time passes. After the celebration of Declan's completion of the police academy, he and Alex return home and they look at some old pictures of them from when he was still a slim, pretty blonde girl... The large, muscular bald man, in his neat police uniform, held a picture of that beautiful, smiling, sexy girl with long blonde hair, makeup and impressive cleavage. The ex-Miranda loosened "her" tie a bit and a single tear rolled down the rough handsome face.
