You're sleep deprived and changing in your local gym's locker room when your body suddenly tingles and erupts with warmth. "Aghh!" You double over, trembling as your bones crack and reshape.  

Your muscles melt away while an increasingly large set of tits inflates upon your chest. "W-- What!?" You cry in confusion, your voice climbing a few octaves.

You moan and place a hand against the wall to support yourself as your waist pulls inward, quickly followed by your ass expanding into a perky, round shape. Your newly pronounced hips can bear your womb as your prostrate is repurposed rapidly. You're so distracted you don't notice your fluffy tail or your ears relocating atop your head.

"W-- Wait! No!" You squeal as your testicles ascend into your pelvis, and your penis recedes until it's nothing more but a fleshy nub nestled within the folds of your newly-forming labia.

As you grope your crotch, you cry out as an orgasmic burst shoots through your clit, causing your body to tingle with delight. "Ahhh!" To finish the transformation your workout clothes morph into a sports bra, a women's tee, and short pink workout shorts.

After regaining your senses, you look in the mirror with an expression of disbelief. You tremble as you raise your shirt and gawk at your massive, perky breasts.
