The night you decided that you would go to sleep early, because you couldn't wait for the next day to come. When you were lying down your cell phone rang, it was Helen calling you.
"Hello dear, I'm glad you answered. Are you alright? You missed school without warning and I couldn't get in touch with you, nor did your parents know where you were." your girlfriend said
"I'm sorry for making you worried. I had an appointment for today and I have great news, but I will not say what it is now. Tomorrow I tell you what happened, I'm sure you will love it." you said to her, said goodbye and hung up, going to sleep immediately afterwards.
The next morning you woke up early with the doorbell ringing, you looked out the window and saw that Helen was there. You got ready quickly, meanwhile your mother opened the door for your girlfriend to enter.
Soon Helen came into her room saying "Good morning darling. I'm sorry for coming so early, but I was really looking forward to what you might want to tell me. So, what did you do yesterday?"
"I just did the procedure and now I have a vagina." you said
"You did what? Do you have any idea how much trouble you might have gotten into with this? The school clearly says that all students must have a penis." Helen said
"I know that very well, but no problem, I still have my dick." you said
"What do you mean by that? You just said you have a vagina and now you say you still have your dick. Do you mean you have both now?" Helen said
"Exactly, see for yourself." you said and showed her your vagina behind your balls.
"But how is that possible?" your girlfriend asked. You told her everything that happened since the day she cried until then. "This is really cool. But you're going to be in trouble if they discover your vagina, aren't you? You didn't have to do this for me, especially since it was an illegal procedure." she said
"No problem, remember that school rules require that we have sticks, but as far as I know it does not prohibit us from having a vagina." you said
"Looking at it this way, you're right." Helen said. You then notice that she was stroking her half-hard cocks through her pants.
"I see that you are trying to take my female virginity. We still have time left, how about we do that right now?" you said
"Can I really?" she asked
"Of course you can. I've let you fuck my ass several times, my pussy is the most natural." you said.
Then she took off her clothes and you also undressed completely. She grabbed you from behind, bent down and started running her finger over the lips of your pussy, following it up to your clit. Then she put the fingers of one hand inward and began to stimulate your clitoris with her tongue, meanwhile she stroked her cocks internally with her free hand, making them harder and harder. The stimulation made you hard and you wanted to jack off, but Helen forbade you to do that. Suddenly you felt a very strong sensation spread through your body and simply lost control over it for a few seconds. You already had an idea of what had happened and your girlfriend made a comment that confirmed that you had your first female orgasm.
Without giving you time to recover, Helen stood up and tried to penetrate your pussy with her two dicks, but she only managed to get one inside, the other passing between your legs.
You had no idea what to do, but when you looked back, you noticed the elastic accessory she was using to tie her hair. You borrowed it and used it to attach her exposed cock to yours so that the both would rub each other at each thrust of her, an idea she loved and you had the impression of feeling her dicks get even harder. With your free hands you placed one on your belly to better feel her cock inside you through the bulge it formed, with your other hand you stimulated her exposed cock's tip.
Helen couldn't take much more, spitting her fucking cocks inside you and in your bed, with that you also came, your orgasm being much more intense than you expected since it was the female and the male at the same time.
After your orgasms you looked at each other with a satisfied smile on your face and, before you could say anything, your mother shouted from the kitchen saying that breakfast was ready. You and your girlfriend cleaned up the best you could and got dressed, then went down to eat with Helen saying that you had to give her the address of the hospital where you did the procedure to have your pussy.
On the first Friday after the revelation, your girlfriend went to the hospital to undergo the procedure in which she would go out having a vagina again.
