You watch as your girlfriend becomes starts flexing with her new arms, that have been given muscle to them, and start to panic if she plans on destroying her own bedroom with how big she was getting. You notice her pants start to rip as you held on to the idol she was rubbing, knowing that she might rub it more.
You see that the muscles started growing on the thighs first, as you get off the bed, and the muscles continued at her knees, then her ankles, and lastly her feet. Half of her pants got destroyed, along with her shoes, and socks, as she tries to get up, and follow you. It was like your girlfriend was wearing a sleeveless t-shirt, with a pair of shorts, but as she starts to get off of the bed, and follow you out, you notice her flexing more, as if she was posing for some kind of body building commercial.
