Help her

"I did not expect it to turn out like this, so I will help you now. If you send everything I tell you to the group we created, then I promise they will have no doubt soon, that it was not you who send that picture and messages. And right now that is the most important thing for you, isn't it?" Of course it was. Sure, her life at home was pretty much screwed, but if she did not manage to fix that group chat, her social life, her school friends and basically everything else was as fucked up if not worse.

"Okay, so what do I do?" She probably would have just claimed it wasn't her and the picture was from the internet, but if Derek had a foolproof method, that was better.

"Well, the easiest way is to just proof it. Send a picture of your pussy instead now, full body with skirt up works too, so they see yours looks different." Right. Her mothers pussy did look different then hers, so if they have something to compare they would see it wasn't hers. She was already out of her skirt and spreading her legs in front of the mirror as a thought struck her.

"Wait! If I send them to compare, they will know it wasn't me... but they still will have the new picture of me then, won't they? So is there another..." But she was cut off by him.

"Linda, really? This is to safe your own modesty. These guys will know that your new picture is only to proof your innocence, so they will delete it instantly. Trust me, noone will safe the picture. But since they probably did safe the first one, you should remind them four to five times a day with a close up of your real pussy." Now she felt silly for asking. These guys were all honorable people, and that was exactly why she HAD to send them nudes so often, because they would never keep them.

With the push of a few buttons she did take the picture. Some more to just be sure and then she send them all, after Derek assured her once more that more were better, just to proof they were not faked.

"Now, Linda, there still is a problem left. On all those pictures, you still have that toy in you!" He gestured down and just now did Linda notice the small vibrator she had in her. How could she have forgotten it? "Don't worry. I have a solution for that as well. You have gained their trust by being honest with the pictures, so maybe we can slip in a little lie now. Just tell them you have a serious mental health condition. You will suck every cock you see, even if you don't like it. The only way to stop this is to have an orgasm, but that also only keeps you safe for 5 minutes, so you always have a vibrator in your cunt, because it helps you. The illness is called whoreitis"

While he spoke Linda was typing. She was not seeing that as a good solution, but she trusted Derek. She somehow knew that if she did as he said, everything would turn out alright.

"Now, I will leave you alone with Emilia for the next 15 minutes. I will get ready for school as well, now. So you two have fun." He said and left. As Linda turned back to her mother she saw a horrifying smile on the adult womans face.
