Natalia has been lifting seriously in the gym for just over a year now. She is disappointed that she has not been able to make the gains she was hoping for. She sees all these big, beautiful, muscular women at her gym and wants so much to look like them. She approaches Renae, a Professional Female Bodybuilder and asks her if she has any advice to be able to build a Physique like hers. Renae Lets Natalia in on a little secret and tells her that there is a new Experimental Growth Hormone that all the Professional Bodybuilders are using for massive muscle gains in a short amount of time. As she pulls a syringe out of her gym bag, Renae warns Natalia that there are some side effects that come with the drug. I want to gain as much muscle as a I can regardless of the side effects Natalia replies as she bends over and allows Renae to inject her.
I will leave you to workout says Renae as Natalia begins with bicep curls. After the first set Natalia notices nothing and thinks that the drug is useless. As she begins her second set, she notices her muscles start to grow as she looks at her biceps smiling as veins appear on the surface. As she starts her third set, she is amazed as she keeps getting bigger, harder and vascular but also feels other parts of her body grow as her clit becomes huge and swollen. By the fourth set Natalia has gained so much muscle she can hardly believe her eyes but is shocked as her clit has now turned into a hard veiny cock. By the end of her final set Natalia explodes with pleasure as she achieves the ultimate pump as Renae hears an almighty roar from across the gym. As she walks over to Natalia, Renae can hardly believe her eyes. Standing 7ft Tall and packing 300lbs of pure muscle, Natalia hulks out in front of her as she says to Renae "you never told me the drugs would make me grow a massive cock" as she pushes Renae to her knees and demands that she sucks it dry. All Renae can think is "I've created a Monster" as she gags on Natalia's massive cock.
