Its Sara your 14 year old BFF from school, who lives across the street.
"So did your Amazon Package arrive?" Jenny asked Sara which she answered your question by saying "I ordered a package of special candy in the mail but it got lost. I think that they might have delivered it here.
The description of it is that it's a white bottle with pictures of dragons on it. Have you received anything like that?"
"Why yes, I picked it up and took it inside do you want it now? I'll get it for you anyway."
"Here it is Sara" You said kindly, and with that went to your room to talk about what you'll do during the weekend and after about an hour you were feeling peckish.
"You mentioned earlier that the package was some sort of candy?" Jenny inquired. "Yes it is described as candy Jenny, would you like some?"
"OK I'll have some of it, what are friends for anyway?." So Sara and Jenny grabbed a handful of candy from the large bottle.
"Ohh, I don't feel so good Sara, what was in that candy?"
"I don't know Jenny, but you're not the only one feeling not well"
Then they fell to the floor with a thump that roused Mark from his study and concerned he ran up to see what had caused it.
As Mark opened the door he saw that Jenny and her friend Sara thrashing about on the floor, having what appeared to be epileptic seizures.
His eyes must have been playing tricks on him because they grew and developed scales across their bodies.
Sara grew upwards while developing scales all over her body when she snapped her neck to look at him he was stunned as her eyes turned from normal eyes to elongated reptilian orange eyes. She packed on muscles lots of muscles about 200 pounds of them as she finished growing at 6'3". You watched as her clothes ripped to shreds to reveal that her entire body was covered in scales and that a muscled tail was growing out of her spine to a length of 2' the final changes was that her breasts grew to B size.
Mark then watched nervously as similar changes happened to you but there was some changes mainly that you were larger than Sara by about 2-4" but apart from that the two of you were very similar.
Mark slowly and cautiously walked towards the two of you as you woke up.
Sara and you looked at each other and looked towards your now little brother.
You asked Mark "Would you like to have some of them?"
