Cock Ring wanker's

I was in a sex shop thinking of buying a new metal cock ring but I wasn't sure what size would fit my cock, the guy in the shop advice me that 2 sizes would be a good fit and offered to let me try both sizes out before I buy, he asked me to join him in the back shop and said I could try on both cock rings, so pulled down my jeans and Y fronts and pushed my shaft and balls through the first metal cock ring, the first ring was a little tight so I tried the larger ring which felt comfortable the man in the shop adviced me I should get my cock hard to make sure the size wasn't to tight, so I agreed and started stroking my cock after a few minutes I had a raging hard-on my helmet was purple veins flushed and pulsing as I stood there wanking in front of him, he asked me if I had ever thought about getting a prince Albert piercing, he said just like a cock ring it makes cumming more intensive, he then pulled his cock out to show me his cock with a prince Albert piercing and started pulling his cock to hardness. Feeling horny watching him wank his hard cock I asked if he wanted cum on each others shaft, he agreed so I moved closer and aimed my helmet at his shaft and helmet and spunked a massive load of spunk over his cock head, shaft and rubbed the final blob of cum on his ball sack. He then told me he was ready to cum so I cupped his balls and rubbed my helmet against his helmet waiting for his cum to be loaded onto my dick , he shouted I'm cumming I said empty out those salty balls mate he spunk creamed all over my shaft, hemet and balls. I bought the cock ring and leaving the shop without cleaning the cum of my cock, I had cum running down my leg and smelling of spunk.as I left the shop with my balls drained.
