"It says that this stuff is some sort of enhancement serum, designed to promote muscle growth," Tiff read off the side of the carton.
"You mean I just drank some sort of steroid?" Katie took the carton from Tiff to see for herself what it said. There were no warnings or serving sizes mentioned and the same went for ingredients.
Thinking the situation over Tiff spoke, "It's probably just some sort of health drink component or a brand of protein shake that we've never heard of. The name does sound sort of foreign, don't you think?"
Katie rubbed her shoulders, feeling a dull ache starting in her muscles, probably from thinking about what the milk might have in it, "I guess so."
When she saw Katie's discomfort Tiff decided to offer her some assistance, "You look tense, want me to give you a back rub?"
It was Tiff's deep, dark secret that she had a crush on Katie, but didn't have the courage to bring it up. She didn't want to lose her friendship entirely so she kept her feelings hidden. To the rest of the world she seemed an ordinary girl and she even pretended to be interested in guys, though she knew in her heart that she was a lesbian. If Katie let her rub her back she would be able to pretend that they were more than just friends for a short time.
"A back rub sounds great right about now. I didn't realize it, but I'm starting to ache all over, must be all the textbooks we have to carry around during the day."
Tiff couldn't believe her luck. Quickly she went over to the table and pulled out chairs for them. Once Katie was seated and in position Tiff lifted the back of her shirt and gently began to massage her back.
Letting out a sigh of contentment Katie wiggled her shoulders, "That feels nice."
"Really?" Tiff tried to keep her voice neutral, wondering if Katie might also be a lesbian, or if she was just really enjoying the massage. To prevent herself from thinking inappropriate thoughts about her friend, something becoming increasingly difficult as Katie made small noises on relief, Tiff tried to start up a conversation, "You know, you should really get involved in sports. I had no idea you were so athletic."
"What do you mean?"
"I mean you've got a better body than some of the guys in our school," Tiff realized that something like that didn't count for very much coming from her, she preferred the bodies of girls to those of guys, but Katie was pretty well muscled. It was the level of fitness that didn't come without working out.
As if deliberately missing the point Katie laughed, "Yeah, but with some of the guys that's not all that hard. I don't live off of pizza and potato chips."
"Please, there's more to it than no junk food. What's your secret?" Against all hopes she was starting to think that Katie might really be a lesbian albeit one of the more butch persuasion. If she was she hid it very well, maybe she worked out in secret. That struck Tiff as a rather erotic thought and she found herself imagining Katie lifting weights, shirtless, her small breasts jiggling with every move. Tiff wasn't sure how she really felt about that, since she did like breasts and super feminine looking girls, but Katie was a friend and the possibility of her ending up being something more was too good to be true.
"Seriously Tiff, I'm not all that..." Katie trailed off when she got a look at her arms. Her muscles were far more defined than she recalled them being, not to the point of being bulky, but to the point where they made her look like she frequented the gym, "Tiff, stop for a second, I think that milk really is doing something to me."
Backing away, Tiff watched as Katie stood up and examined herself. When Katie lifted up her shirt to take a look at her stomach they both made small sounds of surprise. To say that Katie had six-pack abs wouldn't be the most accurate way of putting it, but she was quite close to that point.
Firm muscle flowed smoothly under her skin as she examined herself, shocked by what had happened to her.
"Tiff, I feel stronger," was all she could say to sum up the situation.
