Erin was having fun in her new body, being a tall and strong male she enjoyed viewing things from that height. Meanwhile his brother's friend Philip on Erin's body layed sitting on the couch. He was dissapointed, he could enjoy being in a female body, but he couldn't enjoy it because it wasn't developed enough. While Erin decided to play with her new strenght, Philip decided to check the machine again and he discovered a new button he hadn't seen before, when he pressed it a screen turned on and read select age. And two arrows, one up and another down. He decided to press the arrow until the screen read "new age: 16, confirm?" He got inside the machine and pressed the button. He saw as his body started changing, his chest grew showing two C sized breasts that got his blouse up revealing his new curved belly, he felt as his hips got wider and the skirt was torned to two, luckily the underwear stretched with him. "Wow, wasn't expecting this" Philip then went to the bathroom and looked at his even newer self at the mirror. He was now a 16 year old version of his friend's sister. He wanted to explore more about his new body, when he heard Erin (in Philip's body) and his brother Harry came in. "Is that?" Said Harry "Yes" interupted Philip "the machine can also modify our age!, look at me! Am now in your 16 years old sister's body" "thats amazing man" said Harry, "but can you explain why you are dressed like that?" "Well" said Philip "what happens is that the clothing doesn't grow with you"
Philip waited in the couch with Erin as Harry went to find something to get Philip dressed. While they waited Erin asked Philip many questions "what do those feel like??" said as she pointed to her (future) breasts, Philip didn't knew what to answer. "Well, they feel odd, I feel like am loosing my balance" What Erin asked next really got Philip by surprise, "can I touch them?". "I think so, I mean they are, or are going to be, nevermind, do it" As Erin placed her (Philips) hands on Philip's (Erin's) breasts Philip felt something he had never felt before, a level of pleasure a man could only dream of. "Well, how was it?" She asked when she finished. Philip just looked at her, "you will learn when the time comes". "One more thing" said Erin. She swiftly got closer to Philip and kissed him in the mouth. When they separated Philip looked at Erin without knowing what to say, at that moment Henry had returned.
