A discovery

They dashed up stairs like giddy children. As they closed the bedroom door Sarah couldn't resist kissing Matty and they both started to get into it until Sarah broke it off "If we start this we will never get anything done. Having said that let's get your clothes off"

They both stripped down and Maty still had a tendency to cover herself but Sarah led her into the en suite and turned on the shower "Hair first. You can have any hair you want so what do you go for?" she asked.

"Like yours" said Matty "Raven haired and long."

"OK, lets change mine while we are at it. What would you like me to be?"

Matty blushed "Blonde and wavy, kind of Marilyn Monroe but longer."

Sarah smiled, "Classic bimbo?"

Matty nodded and they both got in the shower a moment later they stepped out and towelled off. Matty ran to the mirror and played with her hair in disbelief. "This is amazing, let's get dry I want to see what yours looks like." Sarah was definitely now blonde but her hair was wet and plastered to her head. A little attention with the blow drier and both of them looked like they were fresh from the salon. Matty was running her fingers through Sarah's hair "This is really tuning me on, you look so hot like this" said Matty.

"You too baby but we have only just started. Come and sit down, let's do lips first. How big do you want to go?"

"I don't know, probably not as big as yours just a bit plumper and a bit more inviting. They are kind of thin right now I think big ones might look weird."

As Sarah applied the balm she imagined what she wanted Matty's lips to look like and thought about them changing over a few seconds. As she dabbed the balm on Matty's lips swelled in front of her eyes. A little bit more, a little bit more, right there she though and as soon as she thought the change was enough the lips stopped growing. A thought struck her and she applied more. As she thought about it the lips shrunk but it was supposed to be growing balm. She took the lips back up to where they were before but this time she didn't apply any extra but still the lips plumped up as she touched them. Suddenly she was **** to try something so she said "What do you think?" and stepped out of the way so that Matty could see.

"Oh my god it worked, they are so good, they even look natural" said Matty now holing her face close to the mirror to get a closer look.

"I just need to go to the bathroom, give me a minute." Matty wasn't even listening, she was too busy making kissy faces in the mirror.

Sarah dashed into the en suite and stood naked in front of the mirror. She grabbed her breasts and imagined them growing, they swelled in her hands and Sarah nearly fell over in shock. She stroked her arm and imagined olive skin. Like water on paper her skin changed colour and spread over the rest of her,she wan her hand over her face and legs and reached around to her back, She turned only to see the skin change from her light tan to a beach bunny one. She put her hand to the throat and began to sing a relaxed note and pictured her voice raising and without any effort on her part her it raised. She tried saying a few words. The whole timbre of her voice had changed. It was slightly breathy and higher. The perfect bimbo voice she had in her mind.

Mercifully for Tom her gullibility on this issue was still in effect and she suspected nothing more than the experimental treatments had changed her. She was worried and wanted to talk to Tom about it. She threw on a robe which had difficulty covering her humongous tits and dashed out saying "Back in a minute." Matty hardly noticed but was surprised by how Sarah sounded but by the time she could react to it Sarah was down stairs.

Sarah rushed into the kitchen where Tom was cooking "Baby I need to show you something"

Tom turned around and was surprised by the blonde bombshell in his kitchen before he realised and said "Sarah?"

"Yes I made a little discovery, watch." She pulled open her gown and Tom grabbed his crotch so she covered herself up again "I need you to concentrate, here." She took his hand and from being on the brink of orgasm he felt numb and his cock went floppy.

"How did you do that?" he asked.

"Honestly I didn't even know I could do it with out touching you directly until now. Hang on." She stood there staring at him but tnothing happened. "I was trying to make your hair pink, give me your hand." this time she watched his hair go from bright pink and back to normal. "What ever has happened I can now change myself or others just by touching them. I'm freaked out." She hugged him and her massive chest pushed against him, he felt aroused but he didn't get hard. He decided not to mention that as he could do with the respite.

He needed to reassure her. The wish had always made the changes come from her the creams were just a ruse. He had hoped that they would limit her but it clearly didn't work like that. He probably shouldn't have said about how she could speed up the change. Anyway he now had to do damage control. His mind worked as she held on to him in her worry. "When I contacted the people about using it on other people they said it was to do with the active property of the cosmetics were tied to you. It seems that they have bound themselves to you making you effectively the cosmetic." He really hoped she was buying this "It makes sense that you have to be in contact, you are the cosmetic now. Don't fret about it, think how convenient it is but... I know you have already told Matty but you must be very careful how you use this. It wasn't legal and we could get into some serious trouble if this got out. Help Matty out but maybe just keep the changes between me and you and maybe don't change yourself so much that people couldn't explain it. I hardly recognised you when you came in."

She looked up at Tom a little teary "You are great you know that? You are right. I hadn't even thought about the repercussions. Oh but what about Matty, people will notice her changes?"

Tom thought about it "Maybe she should move in for a couple of weeks. She can always say she ran off to get surgery but was too embarrassed to say."

Forgetting her rules she reached up and took Tom's face and kissed him as a wife kisses a husband "I love you."

"I love you too."

"You realise that means you are in the spare room while she's here?"

Tom sighed "Yea, I'll cope."

"I'll be sure to nice and vocal for you" said Sarah and she looked baffled when there was no reaction from Tom. "Oh yes" she touched his hand.

Suddenly he was back to full arousal and her proximity was getting him off "Oh I thought you'd forget". Sarah winked and started to walk out but Tom stopped her "You might want to tone those down a bit" he said pointing at her chest.

Sarah looked down at them "Oppsie, you are probably right." she opened her robe and grabbed her chest and they shrunk down to the size they were before still big but no longer comical." She heard Tom grunt and looked over to see him really close to cumming. She gave him a shimmy and it pushed him over the edge "A little thank you for your help. See you later."
