After dark, the park is officially closed but a gate at the rear is left open for the men to gather. A discreet survey discovered that a majority of the nightly visitors are men who present as straight in their daily lives – and consider themselves to be straight - but want to have occasional sex with other men. There might be 20 or 30 and boys men present during the summer months, mostly nude but including some voyeurs who remain dressed and who are there to watch. A lot of the nude guys like to have watchers. Some wank on their own while others look for partners with whom to masturbate, suck or fuck. The night I went, I met Stephen. We masturbated each other then took a pause before resuming. He told me he lived five minutes walk away and came to the park with his family at weekends. Naturally his wife didn't know his secret. He'd masturbated with other boys as a teenager but stopped at university. In his mid-30s, he'd began to include the memories of his adolescence in his masturbation which he'd never stopped doing whenever he had the opportunity. He'd learned about the park's night time activities by accident and eventually summoned the courage to go there. We had another wank together then took a stroll. A middle aged man was spread-eagled face down on the grass surrounded by four young men who were taking turns to fuck his ass. In the bushes, we could see a big black guy having his cock sucked by a white teenager and that turned me on so I asked Stephen to masturbate me while we watched. We were there for about two hours and when we left Stephen invited me to his flat for a drink where I met his wife Janice. She was a nice woman who innocently had no clue that only shortly before, her husband and I had been wanking each other just 200 yards away which was very erotic for me in itself.
