Seems like a normal day

I wake up, and go to the bathroom to brush my teeth. Upon returning to my room, I take off my pajamas and slip into a thong, a comfy pair of neon yellow yoga pants and a black sports bra under a white loose shirt. I head downstairs for breakfast and see Amy sitting on the couch talking to someone on the phone. I decide to not pay her too much attention and whip up a healthy oatmeal breakfast. I am about to head out when I hear Amy say she will see them later and ends the conversation.

Standing in the doorway I look back towards Amy who is sitting on the couch and say "Hey Amy look, im sorry about last night, I overreacted a bit and I shouldn't have been so mad at you over something so small. We cool?" Amy looks up at me and says "Yea, see ya sis" as I walk out the door.

I get into my car and ride to the gym. Upon getting there I walk past the security desk like always and to my yoga classroom. Once I get there I set up like normal and soon enough my girls start walking in and before I know it I am teaching.

A few hours pass and I go out for lunch before returning back to work to finish the rest of my lessons for the day. As my last class ends I go to my car to put away my yoga mat and grab a towel that I put into my gym bag.

I walk back into the gym and decide to get a workout before the gym closes in an hour and a half. I start off with some squats and leg press, before moving to a station with mats to do exercises like hip thrusts and such. I look at the clock and see that the gym closes in an 40 minutes. I decide to go to the treadmills and do a fast jog at speed 6 for 20 minutes.

After finishing all my exercises I find myself quite sweaty so I go to the girls locker room. Since the gym is closing so soon, I find myself there alone and don't have to worry to much about being seen my anyone. I strip naked, leaving all my clothes on my bench, and hanging my towel over the railing of the shower. I want to leave my car keys right there with my clothing but decide to toss them into a locker just in case.

I walk to the shower, close the curtain and turn on the water. It feels so nice to have the warm water run down my skin after a workout. I hear on the loudspeaker "GYM CLOSES IN 10 MINUTES!" and decide to wrap up my shower. As I reach for my towel, I find it gone. I look at the railing where I left it, but it is no where to be seen. As I open the shower curtain to look for my clothes I find the bench completely empty.

"No fucking way!" I mutter to myself, feeling sudden panic. I have no clothes and no towel and the gym is closing so soon. I can't even call out to anyone for help because the only people still left are the security guards. I take in a few deep breaths before gathering my wits. I probably have 5 or less minutes to get out of this place before security locks it down and I need to spend the night locked inside naked.

I open my locker where I left my keys and exhale a sign of relief to at least find them still there. As I grab them I look around the corner peeking out of the girls locker room and still see a security officer sitting at the main desk. Deciding it is way too risky to try and get by him I decide to take the back entrance out, the one I knew about only since I worked there.

As I open the backdoor up and step outside I hear it close and lock behind me. "No turning back now" I think to myself. I start walking fast towards my car when the motion sensor lights turn on. I feel the bright lights on my skin as I am standing there completely naked at 10pm outside the gym. I quickly look around and that's when I see them.

Three guys standing there smoking about 60 to 70 feet away now looking directly at me. I watch them drop whatever they were smoking and start walking towards me.

Scared for my life, I run as fast as my legs could carry me back to my car. I look over my shoulder and see them chasing me as one of them yells "HEY BRING THAT ASS BACK HERE!" I just into the car, jam the key in the ignition, turn on the car, quickly put it into drive and slam on the gas. I swerve out of the parking lot and onto a main street, running a red light before I start to slow down. The rest of the ride home is normal but my hard is still beating fast from that encounter.

Upon arriving at home, I get out of the car and run to the front door opening it up and bursting through it.

Roy and Amy are sitting on the couch and I see my clothing and towel right next to them, they look at me. Quickly I cover my tits with one arm and my pussy with another as I squeeze my legs together.

"HOW THE FUCK ARE MY CLOTHES HERE?" I yell as I go grab a towel and wrap it around me, while grabbing my clothes into the hand not holding the towel.

"Well Amy thought it might be funny if while you were at the gym shower, if I stole your clothes and towel and brought them back here to spook you a bit" I heard Roy say.

"TO SPOOK ME? I HAD TO RUN FROM THREES PSYCHOS WHO COULD HAVE KILLED ME TO BARELY GET BACK HOME AND YOU WANTED TO SPOOK ME? AMY YOU ARE A FUCKING IDIOT, I CAN'T BELIEVE YOU ARE MY SISTER!!! AND ROY GO TO HELL YOU FUCKING BITCH!" With that I storm upstairs and slam my door shut.

I sit there on my bed filled with fury that this was all Amy's doing. I want to call up Mom and Dad but I don't want to ruin their vacation so I decide to hold off.

I sit there for half an hour or so and change into my pajama pants and a tshirt and then my door opens.
