As I walk in to the gym, I went straight to the locker room, to put my clothes away. When I got out the locker room,  I was just wearing some shorts and my tank top. It was only me and this girl in the whole gym besides the workers. I notice her, she was a little chunk, but had a sexy face. She was wearing some skin tight leggings and a t-sirt.  I waved at her, so I can be respectable,  and she will know that she is not alone. She was lifting some weights. I decided to go straight to the treadmill,  so I can do some cardio.  I was facing her, every once a while I will notice her staring at me.I  decided to get her hot and bothered.  After the treadmill,  I went to the weights,  but first I  took my tank top, so she can see my ripped upper body.  I saw her lick her lips, when I did that.  Then she decided to tease me and touch my butt, and flash her ass or her tits. When I wasn't looking, she came out wearing a sports bra , and her leggings pull down so you can see her panties and some of her butt. I instantly got hard by looking at her. I  tried to adjust myself without her noticing. She caught me a few times.  The next time she came out wearing her sports bra and some panties. I was shocked. I knew she was trying to tease me, so I teased her back and I took my shorts off and I was just wearing a very revealing red jock strap underwear. It showed the imprint of my dick and it had all my ass showing  she came up to see and told me that I am crazy, i like that, and let's go have some fun some where. She didn't expect me to be like this, but I was. Then I just took off my underwear and now I was naked.  She was completely happy with my size .  She went down and start giving me head.  She was amazing at it.  I almost came a lot, but she stop and said wait . She got naked. Push me down on the bench press bench and started to ride me until weboth came.  We both got dress and left
