Personal Best

No matter how many times she saw herself in the mirror, she was always a little surprised when she saw how big her arms were these days. It had been almost a year since she’d first listed a barbell, and her muscularity would have been absolutely incredible to the uninformed observer.
Not that her ability to gain strength extremely quickly was any real surprise. She came from a long line of powerful women, and she herself was probably four or five times as strong as a man with a similarly-sized bicep would have been. And she was the runt among her sisters, the lazy middle child; her younger sister was quite a bit larger than she was, while her older sister regularly broke world records for strength and endurance.
She flexed absently and was rewarded with a powerful pump. Impulsively, she pulled out her phone and snapped a picture, enjoying how her flex made her decently large breasts look even bigger. This is perfect, she thought. Just enough muscle for no one to mess with me, but I’ve still got rockin’ tits.
Energized, she skipped out the door and down the block toward the gym. Today she was sure she’d smash her personal best.
