"Hold it. Hold it! Watch your form," Sierra urged, as Alex strained every sinew to keep the heavy barbell in her grip exactly the way the muscular trans girl had shown her. It was so hard; she'd been weight training for what felt like hours, and her body was aching beyond belief. But still, as always, working out felt good. "OK, and... drop. Great job, that was the last one!"
Alex carefully lowered the barbell down onto the mat, and then promptly collapsed onto the floor, heaving with desperate breaths. That was the hardest workout of her life. She hadn't known what she was in for when she'd asked Sierra to teach her how to weight train. She'd just been filled with the sudden, powerful desire to emulate Sierra's muscular form. She'd been surprised when Sierra accepted. Then, even more surprised when it turned out that, while her usual playful, cocksure demeanor didn't disappear, Sierra approached her workouts with the attitude of a drill instructor. She put Alex through her paces mercilessly; thanks to her, Alex was spending more time in the gym than ever before. She was there every day now - she had a cardio day, a core day, an arm day, a leg day, and more. It was hard, and it was interfering with Alex's studies more than she was comfortable with. Every night she promised herself she was going to make up her work, and every night she just collapsed onto her bed with exhaustion. But it was worth it. Not only had she shed more weight than she'd ever imagined possible in such a short space of time, she could also feel her body becoming more toned. It was subtle, but her arms and legs were firmer, more shapely. It was an amazing change. But especially now that she'd gotten to know Sierra, Alex wanted to go further.
"Good workout!" Alex looked up and saw Sierra grinning down at her. She blushed. Sierra had that effect on her. Being around the tall, imposing girl made Alex feel weak, flighty and even a little submissive. It didn't help when Sierra made some kind of crude comment reminding Alex of what they'd done in the showers the time they'd first met. Or any of the times they'd fucked since then. Alex had become one of Sierra's regular booty calls, although far from her only one. That was another change Alex never would have imagined before. But she just couldn't help herself! Working out got her so hot and bothered, and Sierra made it so easy, so fun, so consequence-free. Besides, it was way better than masturbating - although, Alex had to admit to herself, she wasn't doing any less of that. When she got home from the gym and collapsed on her bed, it was all too easy to spend hours and hours slowly fucking herself into cum-drunk haze. Alex giggled. What the hell was her life turning into?
"Thank you," she said to Sierra, accepting her outstretched hand. Sierra hauled Alex to her feet and clasped her shoulder.
"No problem! You're making great progress. Someday you'll be lifting as much as me!"
"Someday." Alex returned Sierra's joking smile. She'd seen how much Sierra could lift, and she knew she was a very long way from that. But, she reminded herself, as long as she stuck with it then nothing was impossible.
As her breathing returned to rhythm and her muscles stopped screaming at her, Sierra realized something else about her body: she was horny. Really horny. It was a familiar feeling at this point, but no less intense for it. She needed to get fucked. She was aching for it. She eyed Sierra's powerful body hungrily. She knew what Sierra was hiding under those pants, and she wanted it. But still, she blanched at the notion of actually saying that outright. That was just too embarrassing.
"Hey..." Alex said, trying to sound suggestive. "I'm gonna go get cleaned up in the showers."
Sierra replied simply: "Oh, cool."
Alex blinked, and then pouted. This was Sierra's way of teasing her, wasn't it? She hated playing into Sierra's hands, but she was so desperate she honestly wasn't sure if she could bear to wait. Besides... maybe Sierra bullying her wasn't the worst thing in the world, she thought, blushing.
"Maybe... you're thinking of taking a shower soon too?" Alex asked quietly.
Sierra just looked at her for a moment, and then barked a dirty laugh. "Wow. Since when did you become such an eager little slut?"
Alex half-knew it was coming, but all the same she turned completely red and looked down at her feet, flustered beyond words. And the teasing only made her more aroused.
"Well, actually, I've got something else I need to do. Or should I say, someone," Sierra continued, grinning so smugly it made Alex roll her eyes despite herself. "Anyway, didn't you say you were gonna be busy right after this?"
"What? Oh, I guess." Alex remembered she'd promised herself that tonight in particular, she absolutely had to get some work done. She didn't remember mentioning it to Sierra, though. Professor Sinclair had been riding her really hard over her missed assignments, and had told her she was going to be in serious trouble if she didn't submit something in the next couple of days. She'd been trying her best, but it was just so boring. And so hard. She'd never struggled with school before, but now every time she tried to concentrate on the textbook, it was like the words didn't make any sense anymore. The harder she concentrated, the fuzzier and emptier her head became, until she gave up. It was a problem, but Alex couldn't bring herself to care about it. She was tired of living to work. It was high time for her to learn to have some fun and blow off school for once. She smiled ruefully. "Yeah, I'll probably be pulling an all-nighter in the library. I'm gonna need a lot of coffee."
"Huh?" Alex frowned at the confused expression on Sierra's face. "No, I was talking about your plans with Winter."
Now it was Alex's turn to look confused. Plans? With Winter? That was news to her. She'd never even spoken to Winter - she was far too timid to approach the girl she was harboring such an ardent crush on. "What are you talking about?"
Sierra cocked her head to one side. "Winter was telling me about it. You're going to a party with her or something?"
"What the..." Alex had no memory of anything of the sort. She couldn't remember ever talking to Winter, beyond a few words in passing, let alone planning to go to a party with her, but her head still wasn't at all clear. She couldn't be sure, and it was bothering her. Starting to feel a little unnerved, she checked the messages on her phone. A chill came over her when she saw that, indeed, Winter's name and number were right there in her phone, along with a whole load of messages between them. As she read over the messages her jaw dropped open. Winter had invited her to a party! Alex's confusion dissipated, only to be replaced by excited-anxious butterflies in her stomach. It was coming back to her now, just a little, even though the memory was strangely vague and distance, almost like a dream. Yes. Winter had invited to a party. Winter had invited her to a party! Her crush, the girl she'd been dreaming about for months, actually wanted to spend time with her! Alex grinned. Then she checked the time, and the time she'd arranged to meet with Winter. Shit! She needed to get going, or she was going to be late. As quick as she could, Alex thanked Sierra again for helping her out, then raced away to shower, got changed and go home to get ready as quickly as possible.

A little over an hour later, Alex arrived at the address Winter had told her to meet her at, and was looking around for any sign of the goth girl. Maybe she was actually running a little early. At home, she'd been in a desperate hurry to grab something to eat and get ready for the party. Getting ready for parties wasn't something she had much experience with. She'd eventually managed to get her makeup looking pretty good, but she'd had a hard time picking an outfit. She had no idea what kind of thing she should wear. She didn't want to seem like a prudish nerd, but she didn't want to overdo it and look like a ridiculous slut either. In the end she settled for a pink short-sleeved top with a slightly more daring v-neck than she was normally comfortable with, and a black mini skirt that was short, but hopefully not too short. It was a classic combo, she'd convinced herself, and only a little chilly in the evening air.
"Hey there," said a sultry voice from behind Alex.
