I would get a pleasurable feeling inside my lower abdomen when I would climb poles and trees, or just do pull ups during gym class. Pretending to try to climb to the top of poles at school but the real reason was a secret. One time recess ended, but I had not finished my climb. I stayed on the pole in my own world trying to get the feeling. Absent from class the teacher became concerned. After spotting me on the pole I heard her shout. She told me to come down from the pole class has started. When I did not respond she shout at me again and began walking out towards me in a hurried way. It felt so good I continued shimmy the pole. Staying on till I climaxed. She scolded me I knew I was in trouble. I was so embarrassed when I walked back to class. I didn’t think she knew then what I was up to. But I am sure , when I think of it now, she knew what I was doing. I would walk to the local school where the poles were. Tetherball poles, volleyball poles, the poles at the swing set worked just right.. As long as I could climb them. The anticipation gave me an erection. After checking to make sure I was alone I make my way out to the pole grab hold and start climbing very slowly while clamping my thighs together squeezing my erection. Scanning the area concerned that anyone would see me climbing a pole. I physically strain for minutes to get the feeling. My arms and hands in pain and legs fatigued, but still pressing together with precise timing. The last energy left in me was going fast. I struggle ignore fatigue, focusing on cumming. Reaching the point of no return a frenzied struggle. Then, overwhelming waves of pleasure engulf my body, I cling to the pole with my eyes shut.
