Balloon (Patreon)

She discovered early in life that she could focus really hard while inhaling and cause her muscles to inflate like a balloon. She didn't use this ability much, though, because of the stigma associated with women with muscles. But, after getting an athletic scholarship for university where she was offered a spot on the weightlifting team, she decided she should see just how far she could take her body. After just one glorious breath, that left her standing a lofty 7'1" (2.16m, 215.9cm), she decided she should stop before outgrows her dorm room.
