You wake up Saturday morning as you stretch and feel your breasts bounce a little bit. For some reason they felt a little bouncier than usual, but you felt great. You got out of bed and when you walked to the bathroom to brush your teeth and hair a little you saw someone different than you in the mirror. The face was softer and more feminine, the brown hair had lengthened to your shoulders, and when you gasped your voice was more high-pitched. You looked further down your body as you admired your hips and butt which were nice along with your thing waist. You also noted that there was nothing between your legs anymore, but one of the bigger things that you noticed was that your breasts were a few cup sizes larger than usual.
Your sister walked by and said "Hello Big Sis..."
You asked her "Did you know I turned into a girl?"
Your sister said "A friend from your school came by last night and gave an invitation to come to her all girl's sleep over party... She also had a gun similar to that breastinator thingy which made you a girl. She said you could turn back either at school or at the sleep over."
You cursed to yourself and then said "Fine, did my friend leave a note or something?"
Your sister ran to her room and came back with a note and the breastinator and said "She left this and also said to bring your gun."
You looked at the note and found it had the address to Julie's house on it. The girl was fairly popular and one of the first to really interact with you in the locker room. You wondered what she was going to do.
Latter in the evening you entered Julie's house as she greeted you to the door. The large breasted blonde said "Welcome there Jeff, glad to see you come, did you bring your gun?"
You needed and said "so what are we going to be doing?"
Julie said "I invited a couple people from school to participate in a little event of mine. Besides you and me there will be 4 others who are already here. let's not keep them waiting." smiling she rushed you into the living room where 4 other girls with backpacks were in. Julie announced "Now that everybody is here I wanted to announce something interesting we'll be doing here for this all girls party. I got myself in my position a special gun called the Genderator, you can see some of it's affects on Jeff here from school." She pointed to you and you waved shyly as you recognized them from school and they probably recognized you. Julie said "I know you all have some of these special unique guns as well, but i'll tell you all what my gun does specifically. it..."
