You see a young boy sitting with her mother and sister. You decide to try something new by swapping the girl's vagina with her brother's mouth. After pressing the button you see the boy's lips become thinner and wider, indicating that it worked! Your own dick is getting kinda hard at this sight, as you look for more people to swap.
You then see a mother walking towards the bathroom with her baby and what looks like a diaper. You decide she should be the one being changed by trying a new experiment, and swap the mother's vocal cords with the baby's bladder. You're not sure if it worked, but you shrug it of anyway.
You then see a fifteen year old girl walking toward the toilet looking embarassed, as you look closely you see a slight red patch on her white shorts, indicating that she's on her period. You decide you want another experiment and swap her womb with the breast milk organs of a nearby pregnant woman. The change of color of the patch on her pants from red to white indicate that it really worked.
Unfortunately you didn't see your finger slip and press the switch, so that you're now the subject of your swaps again.
