Your Mom said they were running late and was about to leave when Mary said "NO WAY!! if we leave her here someone might come by and see her thinking it's me, and I don't trust Mike to not take advantage of the situation I think she should come with us."
Your Mom thought for a sec. before she said "Maybe your right, Mike clean up and meet us in Mary's room."
"But Mom why do I have to go to Mary's cheer show."
"Mike your sister has to keep her mind on what she is to do so if it will make her feel better to have you to come with us then you are coming. So get into your room and pack some things to wear when you change back while your sister and I pick out something for you to put on now."
"BUT" mike said.
"No buts get in your room and make it fast we are already running late."
Mike went into his room and throw some things in a bag before going back into Mary's room where his Mom and sister helped to get him dressed.
The 5 hour ride to the hotel was a quiet one as Mike did nothing but stare out the window and mope.
They had to do a bit of a shell game to get both Mike and Mary into the room since it was only booked for two but when they got to the room they checked the time.
"OK Mike, Mary and I are going to check in with the competition, you wait here and watch some TV and we will use the medallion before we go to bed."
With that they went to check in leaving Mike to think of the way he was feeling. Mike got into a move on the TV and before long they were back.
Mike checked the time and seen that the 12 hours were up so as his Mom got the medallion he got out his cloths.
Mike took the medallion and touched it to his shirt but nothing happened, in a panic he started to touch the other cloths he had brought but still nothing was happening. Mike started to cry as he said "Does that mean I'm stuck like this."
Sharon thought for a sec. before taking a brand new C-cup bra from her bag "Here Mike try touching it to this and see if anything happens."
Mike looked at the bra "No way, why don't you or Mary try it."
Sharon said "Look Mike if this thing only works once then nothing will happen to you and Mary or me are not about to use it, but if it does work thin something else is wrong so do it."
Mike looked at the bra and protested again before touching it with the medallion.
As soon as he touched it he felt a tingle as her breasts started to grow the 2 cup sizes, "What the fuck" he said as he made a move to get his sisters bra since it was too small.
"WOW" Mary said "I always wondered what I would look like with bigger breasts."
Sharon happened to look at the cloths Mike had brought "What a min. Mike are thous the same cloths you had on when you first changed."
"Ya so what" Mike said.
"Well that explains what the problem is you had your sisters body when you last had them on so the medallion is reading your sister not you, it looks like we are going to have to wait until we get back home for you to change. Now that that is solved get to bed Mary has to be well rested for tomorrow.
Next morning.......
