I was really enjoying the novel from the library and I sat on the park bench reading it. There had been joggers everywhere including young couples, people taking their dogs out for exercise, and a few cyclists.
As the sun began setting there were less people taking advantage of the mild weather and the pleasant botanic environment. I checked my watch and decided to finish the chapter I was reading then leave to walk back to my car and drive home.
A middle-aged man jogged past and stopped at a large tree about 20 feet past me and began doing some stretching exercises.
I stopped reading and watched him for a few moments. He was wearing grey cut-off track pants that were so tight I could see he was circumcised. He wore a loose, light blue T-shirt and sneakers and socks. He looked to be about 40 with greying hair, but his body was athletic and slim, apart from his sprinter's legs with defined muscle definition showing through his tight grey pants. He was about 174cm (5feet 9inches) tall.
He began his routine with assisted arm stretches, impressively high leg raises while holding the tree for balance, and forward bends with his feet apart and slowly rotating to the side, back, and to the other side, forward, then up again.
While he was doing these, I noticed a bulge in his pants. At first I thought it was the creases in his pants that take different shapes as he moved his body into different positions, but on continued watching, I could see it taking firm shape as a large penis, made to look much bigger by the fabric covering it. I couldn't take my eyes off him and at one stage, his erect cock appeared briefly under stretched the elastic of his grey cut-offs and disappeared again.
Then after two more rotations, his penis escaped the waist band of his cut-offs and decorated his stomach, disappearing under his T-shirt as he bent forward and reappearing again as he leant back.
I quickly looked around and saw that almost everyone in the park had disappeared and the last of the cars at the car park were pulling away leaving only 3 or 4 cars unattended.
Returning my attention to the man doing his exercise routine, he stopped to catch his breath and his ample swollen penis lost its hardness and hung heavily and low. I was amazed that he appeared to pay no attention to this clothing malfunction, and as he continued with his twisting exercise, his penis started swinging slightly with each exercise, and from side to side with each twist. I'm straight, but I couldn't take my eyes away from his impressive cock.
I approached him and asked him about his routine. His swollen prick was approaching horizontal at this stage and rising rapidly with visible throbs from his pulse as we spoke. He appeared to be totally at ease with his penis visible and hardening again as we talked. He looked directly at me as I was watching his cock changing shape. He looked me over and told me his routine would suit my body type.
He asked me, 'Are you offended by my cock being visible?'
I gulped in surprise that he was prepared to bring my attention to it. 'No. I don't mind,' I replied.
'Physical exercise seems to have that effect on me sometimes,' he explained.
It seemed to immediately change the whole dynamic of our conversation. He told me he has a physio background and he programmed his own routine.
I asked him to show me. He agreed as he normally repeated his routine so I could copy him and see how it felt. At this time his penis had built into a hardened rod and stood erect and pointed up at an angle of only 30 degrees from vertical. I was impressed with the size and angle of his erect cock. I was wondering if this also meant he was sexually aroused, but I was too shy to ask him.
He repeated his arm exercises and leg raises which I could not match but he was very helpful and told me to do them with bent knees and gradually build them up straightening as much as I could. Over the next few weeks, I would probably notice a difference. With those simple stretches, I could feel the benefit as I started them.
When I progressed to the rotating exercise, I found it hard to keep my balance.
'Let me help,' he said.
He placed one hand on my back at belt level and as I rotated to the side, to prevent me from falling he put his other hand on my stomach below belt level. I didn't want him to touch me, but he was helping me with an exercise routine and I didn't want him to think I was ungrateful. Somehow, I let him continue to touch me.
In spite of myself, I began to become aroused. He told me to rest a few seconds between rotations. I could feel my penis growing during the next rotation and I was sure he must have noticed it as his hand was almost touching it.
