Carried Away (Patreon)

Her friend gave her a shot that was supposed to improve her body's ability to metabolize nutrients and heal damaged tissue. Which it did, among a few other optimizations and tweaks. But, when she then decided to work out after taking an overdose of a new high-powered supplement things got a bit out of hand. The potent combination caused muscle contractions to make her feel pure bliss, and the massive amount of nutrients from the supplement allowed her to workout for several hours straight. All the while, her improved body repaired muscle fibers nearly instantly, ever larger, as long as the nutrients from the supplement held out. The only reason she stopped was due to her stomach starting to painfully growl in hunger. Coming out of her orgasmic stupor, she saw herself in the mirror, glistening with sweat, and realized she might have gotten a bit carried away.

I kept typing this out as "carrier away." No idea why.
