After walking for a few moments Jen's back got really sore.
"Hey Susan, my back is really sore, can you do anything about it."
"I don't know why your back is sore, with breasts those large your back should be super strong."
Jen felt a tingle go through her back and the muscles in her back instantly strenghted. She straightened her back and didn't even feel any pain from her extra breasts.
"Don't people think that it's weird that I'm naked." Jen said just wondering something.
"You were always born this way, in fact you even like to rub it in thier face that you can go naked all the time."
