Lets get to know this body a little.

Knowing she was bigger, she decided to sneak into her mom’s room and steal some shorts. Her mom was full foot taller than her (showing that within her own family Liz was a dwarf) at 5’5, at least she was before Liz’s growth spurts, so her clothes should still be big on Liz. She managed to fit into her own tank tops, but with her recent growth it clung tightly around her breasts clearly displaying her large nipples, and the top ended a full inch above her belly button. Her mom’s spandex shorts however were plenty large, not as large as Liz thought she delightfully observed, but elastic so they shrunk around her waist, and still baggy enough in the legs to hide her cock.

Now with clothing out of the way she had a new urge, to get down to the basement and test her new muscles in her brother’s faux gym down there. Her brother doesn’t have a set time or day that he works out, but makes sure to do it several times a week, so Liz doesn’t know how private it is right now. But Josh always does his homework right after school, so she should have some time to measure herself and at least test her muscles, but maybe more if he chooses not to workout today.
