A buddy of mine opened a gym and I joined up. I was 12 years into my farming career and decided to add some muscle. I'd show up at 6:30 am and start my routine on all the machines. Early was good as the gym was pretty much empty and I'm not a crowd lover.
I found that about halfway into my hour routine, pumping iron would get me aroused. I'm fat so not a lot was showing but I could feel the end of my cock pressing on my gym shorts and precum seeping out. After my workout I'd hit the shower and always stroke out a good cum. The shower room had mirrors so I could watch myself play with my cock, which has always been a turn on.
A couple weeks after I joined, a girl a bit younger than me joined and having her in the gym was good on several levels. She was cute and nice to chat with, PLUS..she wore tights with no panties!...and they left nothing to the imagination. If she wore light colored tights her vulva groove was very visible and of course this got me hard and wet. My shower wanks got even better with pictures in my mind of her yummy cunt. I wondered if she rubbed one out in the girls' shower room.
