I have a full gym in my house so I always work out naked. Went down to workout a few times when I was already excessively horny. I start my workouts with a full set of pushups and a couple of times just the head of my dick touching the floor was enough to set me off. I have cum once or twice while doing seated butterflies. While I always drip precum on my bench during all of my workouts, I really am concentrating so hard on the actual exercises that when I have cum, it was the combinations of clinching my muscles during a lift and the aforementioned state of horniness. I never get erect when lifting, so the cumming came while I was flaccid. Because it's my house and my equipment, I never clean off the precum or those times I actually came. I love seeing my cum lying there on my bench both wet and dried.
