Freshman year of college was over and I was so happy to be back home to see my family and sister. College was fun and I made so many friends but it was nice for everything to finally end and now I can relax.

I realized that I needed to save up money for next year of college so I started looking for jobs and conveniently found one at a gym pretty close to my house as a yoga instructor. This was a perfect kind of job for me, not only did I already love doing yoga, but now I would be paid to do it.

I started working there and it was pretty fun but that left my younger sister Amy who was 18 years old home alone by herself every single day and she would blow up my phone with texts about how bored she was. I tried telling Amy she should find work too but she wasn't interested. So one day I decided to take Amy with me to work to get her out of the house.

Amy protested saying that it would be boring but after about half an hour of re-assuring her, she decided to give it a try. I went to my room and put on my thong, sports bra, yoga pants and a loose tank top and waited for Amy in the car. As I saw the door open and Amy walk out she was wearing yoga pants and only a sports bra. As she got into the car I asked if she didn't feel kind of weird being so exposed but Amy brushed off my worries so I started the car and drove to work.

As we got there, Amy and I got our yoga mats from the car and walked inside the gym. The security guard let me in, knowing I worked there and I told him Amy was a guest and with me and he let her in as well. We started walking through the gym to get to the yoga room and Amy was looking around a lot interested by all the guys there. Amy had a thing for big strong guys, which I guess isn't too unusual for a teenage girl.

As we were about to get to the yoga room, there was a black guy sitting on one of the benches who whistled at my sister and I. I ignored him, but Amy look at him, smiled and waved which brought a smirk to his face.

As we finally got to the yoga room and set up our yoga mats, some of the girls who I thought class to started walking in and setting up their yoga mats as well. I was just about to start when Amy asked where the bathroom was, not wanting to leave the room I told her how to get there. She stood up and left. I started teaching the lesson and an hour passed, so the yoga class was over and still no sign of Amy. As the last girl left, I waved her goodbye and picked up Amy's and my own yoga mats and walked out of the yoga room towards the main entrance of the gym. I was about to text Amy when I saw her on one of the machines and standing right behind her was the same black guy who whistled at us earlier.

Amy was doing some machine to workout her quads and butt which required her to be on her hands and one knee on a platform extending her leg backwards. Every time she did her yoga pants stretched tightly around her ass, I also noticed that the black guy was touching my sister's upper legs very close to her butt.

Quickly I walked over to them. "Um excuse me, Amy we are leaving lets go!" As Amy got off the machine and turned around she asked why we were leaving and I responded that the class was over and she ditched me. Amy told me that the black guy named Roy spotted her when she was going to the bathroom and asked if she needed any help working out so she never came back to the yoga class.

"Alright, well we are leaving now lets go!" I grabbed Amy's hand and started walking with her to the entrance of the gym. I saw Amy turn back to wave and say goodbye to Roy. As she got into the car, I started yelling at Amy. "What the fuck are you thinking, leaving me all alone to work out with some black guy who had his hands all over you?" Amy replied that Roy was very nice and was just helping her work out. "No maybe that's what it seemed like to you, but where I was standing he was rubbing your legs and moving closer and closer to you ass. Why are you so gullible?" What Amy said really pissed me off "Well maybe you should stop being jealous that guys like me more than you! Ok?" The rest of the car ride home was silent
