The first time I wanked with another male was in my early teens.
Our school was catholic and when we reached mid-teens the boys were sent on a religious retreat for a week at some remote jesuit house. Probably to try and recruit us to priesthood. I shared a twin room with a good school friend John.
By day we had all sorts of religious education and services but after evening mass the rest of the day was ours. Most boys including John went out and played sport till sundown, whereas I went to our room for a good wank over a glamour mag.
This worked well until the last evening. I had gone to my room and was in mid-wank when John walked in. It had started to rain so the games were over. I was sitting naked on the bed, hand round cock, wanking furiously over a mag open at centre page of girl with legs spread showing her open cunt.
John looked at me and told me to carry on as he needed to wank as well. He took his clothes off and joined me on the bed. His cock was already hard as he started to stroke it. Then he placed his other hand round my cock and stroked it too. I'd never felt anything so good before, so I placed my hand round his hard-on and began stroking in time with him.
It didn't take long for me to come and I shot a load of spunk on to the pic of the girls cunt. John lasted a little longer before shooting his load on to my cock.
We then went to bed together and played with each other's cock almost all night long. We never repeated this, but I have many fond memories of that night.
