He asked to join them

For a moment you both continued making the faked sounds, before Frank continued. "I asked them if I could join them in feminizing you all."

You were shocked hearing that. "You wh...!" You nearly shouted, but Frank stopped you.

"Psst! Not so loud." He whispered and made some more loud noises to drown out that you two weren't sexually interacting. "I know you all were against infiltrating them a few days ago, but if I don't do it now, when will we get the chance again?"

"Didn't we agree on it being way to dangerous?" You asked.

"Do you think they would simply agree and let me join them without suspecting something?" Frank made some more noises before continuing. "They first have to trust that I really mean it, before I can freely spy."

"But isn't that way too early? We are here just a few days." You replied.

"I assume it will take at least a month before they trust me enough. So the sooner I start the sooner we will have results, that may get us out of here."

You thought about it and agreed with Frank. If you really wanted to infiltrate them, it had to be as soon as possible. Your group was really lucky that Frank was so smart.

"But it comes with a price, two to be more precise." Frank added.

"What prices?" You asked.

"Next week, when we all will get out next change, they will test if I really mean to betray you all and join them. Therefore I think they will ask me to pick the changes done to all of you."

"Lucky, then we won't have to get such bad things."

"Just the opposite." Frank destroyed your hope. "To show them I really mean it, I will have to pick changes you all want least of all, while I also have to keep it fun for the headmistress."

"But that would get you on our bad side?" You concluded.

"Yes, but there is nothing helping it." Frank replied sad about it.

"And if we explain it to them?" You tried to help Frank not to become the enemy in the group.

"The fewer know about it the better." He said rejecting your offer. "I'm telling you because I believe you could lead the others until I reveal myself with good results."

"Shit." You didn't liked his idea, but you had to agree that it was the best option. "And the other price?"

Frank hesitated. It was like he didn't wanted to tell, but then he did. "When I asked to join them, they already tested my resolve. They gave me some pills I will have to take each day."

"What pills?" You asked fearing that they wouldn't be good for him.

"Some experimental ones." Frank answered. "Really strong hormone ones." You couldn't respond because you already knew what he was to add. "They will totally suppress my male hormones and will fill my body with huge doses of female hormones."

"So your body will feminize on its own?" You asked knowing a little bit about how that kind of thing works.

"Yeah, but not like with a normal hormone-therapy." Frank answered. "These things are supposed to be so strong, that they will suppress the male hormones in just a few days, while the female ones should only take a little longer to kick in."

"Shit." You replied.

"But the worst thing about it is, that they said it won't be reversable." You were even more shocked as you heard that. "Once my body will fully cease to produce male hormones and is producing only female ones, I will be stuck like that."

You processed what Frank had just said. "But that would mean you will be as a girl, even when we get out of here."

You could feel that Frank himself wasn't happy about it. He hesitated a long time. But then you felt like you could hear him gulp. "We have been here for quite the long time. We better finish this." Frank made even louder sucking-sounds and signaled you to also get louder.

"Fuck, I'm coming!" You screamed and let out an even louder moan, as if you were exploding.

Frank made some more loud sucking-noises, before he got silent. "Fuck, if I had know cum would be so tasty, I would have done it sooner."He stepped away from you and began putting his clothes back on. "We clearly have to do this again, don't you agree?" He signaled you to agree to it.

"Oh, yeah. You are absolutely right." You played along, knowing that that would be a way to talk about things without causing too much suspicion. You then zipped up your pants.

Frank wiped his fingers over his lips, so his lipstick got smeared. He unlocked the stalls door and you both exited it. "You can leave ahead. I have to touch up my lipstick before I follow. I hope you have no problem with it now being all over your cock?" Frank looked over to you with seducing eyes. For a moment you weren't sure if he really was only acting, but there was no other way than to trust him. So you left the toilet ahead and headed upstairs.
