You barely manage to avoid suspicion.

You stare at your pile of clothes trying hard to make a decision. Megan is looking around your spartan room, not finding much of interest. While you did pick up a few things to decorate with yesterday, you have yet to actually get around to decorating.

Seemingly bored of your room, your friend turns her attention to helping you pick a new outfit. "How about this?" She asks as she pulls a pair of leggings out of the pile.

You've already considered them, and though you can't tell her the real reason you can't wear them is that you're afraid that they'll make a visible bulge from your cock, you try to turn them down. "That would be too slutty, don't you think? I mean, I don't need my ass getting too many looks."

"Honey, ninety percent of the reason to go to the gym is to get more guys looking at your ass. Besides, it's not like it says 'juicy' across the back."

You try to find something else to counter with, eventually pulling out a pair of booty shorts. They aren't so tight as to show off more than you'd care to, but the short length does scare you. You sigh, it's still probably your best option here. Holding them up for Megan to inspect, you say "Are these slutty enough for the gym?"

"Definitely." She replies. "Get them on and let's get moving."

You wait for a moment, expecting her to give you some privacy. She doesn't move, however. Is she expecting you to change in the same room as her? Well, she is just looking at her phone and it's not like you're taking your panties off. You turn away from Megan and with a quick motion, you drop your skirt down to your ankles. You keep your thighs close together to avoid any possibility of exposure as you kick the skirt off your feet. The shorts go on next, after getting both feet through, you slide them up your legs and over your hips. Unknowingly, trying to keep everything hidden has caused you to accentuate your ass while dressing.

When you turn back to Megan, she's still looking at her phone, but her cheeks are flushed as she avoids eye contact. Was she really staring at your butt while you changed? You'd complain, but you find yourself also blushing at the thought of her being turned on by you.

Things seem to normalize as you walk towards the gym. "So, do you like not have a roommate or something? You have a pretty big room to yourself." Megan asks.

"I, uh, did but she left already."

"Damn, after just one day. That's gotta be some kinda record. Well don't let them find out or they'll try to put someone else in there as soon as possible. Wait a few weeks and hopefully enough people will drop out that they won't need the space." You agree with her, mentioning that you haven't been too keen on sharing a room ever since sharing with your older siblings while growing up.

You make only a bit more small talk before you reach the entrance to the campus fitness center. Megan goes first, scanning her ID card and proceeding through the turnstile. You follow after her, though it takes you a few tries for it to accept your card.

"First time inside, huh?" Megan deduces. "Well, I've only been in a few times, but I can show you around at least." Straight ahead of you at the other end of the hall is the indoor track. There's some miscellaneous equipment in the middle of the track, but nothing too important since apparently that room closes when the track team practices. On the right is a large auditorium. As to why it's in the fitness building, you and Megan can only guess. On the left are the entrances to the weight room, pool, locker rooms, and some studios for group classes. The locker rooms open up at the other end to the pool, as well.

Megan takes you to the far end of the weight room where there are quite a few machines for strength training and cardio. Since there's no one else there right now, you're able to chat for the most part even when you're both doing your own things. In between her sets, Megan helps you start on some leg exercises. Once you're comfortable continuing on your own, you see her set up on some of the heavy equipment. You get one hell of a view of her ass as she squats the barbell while you work on some hamstring curls.

After completing all of your sets, you both take to the treadmills for a cool-down walk. As you come down a bit from the last set, you're able to talk some more with your friend. She asks if you want some help stretching after your workout. "Stretching?" You ask her for clarification.

"Yeah," She starts, "if you don't stretch out after lifting you could end up with some soreness. Actually, since you don't seem like you do this very often you'll probably be sore anyway, so at least we can try to minimize that."

Sore? You don't feel sore at all, you just feel like your muscles are fatigued a bit. Nonetheless, you take her up on her offer. Megan has you sit on the floor and reach out for your toes. You can just barely not reach them, but you start to feel the stretch in the back of your legs. You go wide-eyed, however, once you feel her hands on your back helping you to lean in. You try to focus on reaching your toes, counting the seconds, anything to help keep the blood out of your cock for the moment.

After stretching your hamstrings, Megan helps you with your hips. This time it's even harder to stay focused as she has her hands on your bare legs. Focused as you are, you can't tell if she's enjoying it as well. When it comes to your back, your friend helps push your knees to your chest as you look up at her from the floor. You see just the faintest bit of skin under her sweat-soaked shirt and further up, her sweat has even outlined her perky breasts.

This causes you to lose your focus and you panic. You do the only thing you can think of and quickly roll over and head for the main door while announcing to Megan that you need to use the bathroom. You don't look back and quicken your pace as you feel your rapidly hardening dick turn your shorts into a tent. Once you enter the locker room, you find the nearest stall and sit down. You hold your face in your hands as you just breathe and try to avoid picturing your friend naked again. Your hard erection eventually begins to die down, but you wonder if it would get it out of you if you simply brought yourself to orgasm. It seemed like it helped last night, you don't remember having any lewd thoughts after you busted that huge nut.

Without thinking much more, you pull down your shorts and underwear, leaving your exposed cock poking up a few inches from between your thighs.
