It was a damp room, inside which our heroine was, her hands were shackled. "Hmmm..." Being sleepy, she moved her hand slightly and, hearing the sound of shackles, said: "Huh? Chains!?! Where am I?!?" Then, hearing a click sound, she asked: "What is that sound?" And when she saw two test pipes with needles connected to two green solution tankers, asking: "W-W-What is that?" - the needles stuck into her arms. "Augh!" The green fluid began to flow into her body. You could see it being spreading through her veins. She says: "I-I-I do not like this!" While our heroine was figuring out what was going on, her body began to change. The green stuff made her muscles shaking with each second. All the muscles on her body began to tense up and expand. She's getting taller as well. "Gaah!!! M-M-M-Make it stop!!!" It was painful, but tolerable. Finally, she transformed into a fit and beautiful muscular woman. Her muscles were so powerful now that she was able to easily break chains. "Hnghh! Grr..." She starts trying to break free from the shackles. And she managed to break the chains! Our heroine, being freed from her shackles, says: "Oh thank God I'm free..." - then looked at herself in confusion. "But what did that thing do to me? And why?" She notices the tankers, from which the green liquid flows out. "Hmmm..." Uh-oh, she doesn't know why, but she's wants more. The girl runs over to one of the tankers, grabbing and drinking it. "Gulp gulp gulp..."

Each gulp caused her muscles to grow slightly, becoming stronger and more toned. Her glutes grow, shaping, and tightening her pink lingerie. Her thighs expanded out, growing larger to support more of her weight.
