I must initially tell you that this happened in an English Uni hall.
I went off to Uni at the age of 19, being a good hunting boy, who enjoyed cricket, Rugger, and wanking. Going off to Uni from a state school (we call our private schools 'Public' .....I know, but we English are rather peculiar!!)
My first year halls were all male, with two to a room. I'd already worked out how to wank quietly, so thought I'd be fine (Normally wanking every day at home).
The lads in the Hall were great, we all loved sport/pussy/beer, so the first night we all went out, and the group split. I was chatting with my roomate and three of the other lads from our hall. Karl (my roomate) said, I've brought some hot porn you lads might enjoy. All of us cheered him on as we walked back to our Hall.
We all slammed into our room, and Karl dug his porn out and popped it on... we were all laughing at the noises being made and were rather raucus, then it began to go quiet for about five minutes. I was as hard as fuck and intended to bash the monkey hard that night. Karl then said, 'fuck this lads' and pulled out his rock hard cock. The musky smell entranced us all. Karl was now wanking and so we all joined in (rude not to!!). So there it was, five 19 year old lads wanking over a porn vid. The smell and the sound was intense, especially as we had only met each other that morning. Then the cum began to appear, two of the lads had dry orgasms (due to wanking that hard prior to Uni), but the remaining three of us shot for England, and then rubbed it into the cheapo carpet. What a great way to finish the first night, and the start of a spunky first year.
