An Unexpected Sex Change

I had no idea you could cum just from your anus! But I didn't want him to stop! I wanted him to finish as well!

I got on my back again and he went at me as fast as he could. It still felt wonderful and I could see the love and the lust in his eyes. Then he leaned over once more to kiss me. Right as my tongue met his, I could feel his whole body tense up and the head of his penis grow inside me. I could feel his load hitting the back wall of my insides. I continued to thrust my ass against his cock until he couldn't take it anymore.

As he rolled off me, I pulled him in close, looked him in the eye, and told him he was the best I had ever had. He kissed me and laid down. We curled up together and fell asleep.

The next morning when I woke up, the first thing I did was look down. I didn't see any breasts. My girlfriend was laying next to me. She was as beautiful as ever. But I could still somehow feel some sort of residual pleasure from the night before. I knew it had really happened. And I was a little disappointed I couldn't do it again.
That afternoon, I took my girlfriend to dinner and then we went to a sex shop just for kicks. I stopped at the strap-ons. She gave me a funny look.

"What, do you want one?"

"I don't know... Maybe?"

She smiled like I had never seen before.

That night, I walked in the bedroom and she had a plastic dong strapped around her waist. I got nervous and excited all at the same time.

She grabbed me and shoved me on the bed.

"Now you'll know how I felt!"

As soon as she tore off all my clothes, she thrust herself in to me.

It was just as amazing as I had remembered. She was so good at it. I would never again forget how amazing it felt to have my asshole filled.

Once again, as she thrust, I could feel myself welling up. The feeling was impossible to control. She seemed to be enjoying it as well.

All of a sudden, I couldn't hold it anymore. I exploded all over myself. She seemed to have some sort of an orgasm at the same time. I guess we found something we both really like!

I had spent a day as a transgender. And I had become a much better person from it. And I had learned so many more ways to enjoy myself!
