Unexpected Growth (Patreon)

She came across a slightly sketchy looking website with all sorts of supplements for women. Being exhausted from her most recent workout, she picked up some muscle growth serum out of frustration with her complete lack of progress. After getting the serum, she immediately went to the gym, took the serum, and proceeded to do a drug fueled, half day long, full body workout that left her barely clinging to consciousness. Somehow, she managed to slip back into her non-workout clothes and got home, only managing to slip off her shoes before she fell unconscious onto her couch. Some hours later, she awoke to a whole new, unexpected, amount of muscle. Initially frightened by her new bulk, she slowly started to come around as she felt her power and examined her new curves. Now, she's starting to contemplate if she wants any of that website's other supplements. Though, maybe seeing if she can get out of these clothes without destroying them first might be in order.

Got some nice, juicy biceps on this one. Bit of a longer render, though.
