Karyn's night had been fairly boring. After speaking to Jon on the phone she had played on his Xbox for a little while before going to bed. Her lack of a bra was starting to cause her some back pain she needed to lie down to relieve it. Her bed clothes were very similar to what she normally wore. Just a pair of boxers and a t-shirt. She was fairly sure that Jon slept in only boxers but she knew from experience that this would not fly with her. Her nipples would have been irritated without the t-shirt covering them up.
Waking slowly in the morning Karyn at first was confused as to why she was in Jon's bed but the memories of the wishes she had made quickly came back to her. Seeing that she had enough time to have a shower before school, she jumped out of bed. Feeling brave she removed her t-shirt and grabbed a towel before heading to the bathroom. As she was walking down the hall, Jon's sister Zoe was coming out of the bathroom. She didn't even give Karyn's large chest a second glance, being used to seeing her brother walk around in just his underwear. The experience was certainly novel for Karyn. She could never walk around her own house topless and she had to admit the feeling was liberating. Feeling her chest bounce with every step she took a look in the bathroom mirror and saw Jon's reflection with his fairly average chest on display. She took off the boxer shorts she was wearing. They fit her but were still fairly tight on her wide hips. She had to stretch them to get them down over her hips and her butt which was much larger than Jon's.
Making sure the door was locked she decided to experiment a little bit in front of the mirror. Looking down she could see Jon's penis in all it's glory. It seemed to be an average size. "Not bad, Jon boy, not bad at all", she thought to her self. Closing her eyes she started to daydream about some of the guys in school she was attracted to. She was picturing one of her crushes kissing her neck and rubbing her breasts. As her hands came up and cupped her breasts she could feel her nipples quickly hardening and she felt a moistness forming below. Opening her eyes she saw the funny sight of Jon in the mirror cupping his flat, male chest. She though that looked quite out of character but when she looked down she was taken aback by the huge erection that Jon's reflection was now sporting. She had never seen such a thing up this close. It was at least twice the size now and standing at full attention. She was very impressed and knew she would see Jon in a different light when things were back to normal.
Deciding she better hurry so as not to be late for school she jumped in the shower and gave herself a quick wash. She nearly used Zoe's body wash which was the same as she had at home but decided against it. She didn't think Jon would be too happy with her if she spent the day in school walking around as him but smelling like a girl.
Finishing up in the shower she made her way back to Jon's bedroom and got dressed very quickly in a pair of jeans and a t-shirt. One big positive of this swap was that she was able to get ready in no time at all.
She ran downstairs and grabbed a slice of toast before heading out the door for school. It was a short walk from Jon's house to the school and as she approached the wall where she and Jon usually met up before school she could see Jon standing there waiting for her. She had a little laugh to herself at the sight before her. Jon was standing with his hands on his hips waiting for her. He didn't look too happy. His stance wouldn't have looked too out of place on him normally but the fact that he was now wearing a tight pair of her jeans and that the large bra he was wearing, although mostly empty still had the effect of pushing his tight t-shirt out. The outline of the bra was clearly visible through the t-shirt. Karyn wondered if this was why Jon looked pissed. Surely he was used to the idea by now?
