Zip lining in North Wales is a slang term for a gay facial gangbang and rimjob with a group of friends and strangers, where one participant is tied up, and the other participants take it in turns to slide into his mouth, until they ejaculate, and then they move onto the bum hole for finishing. .ie at the bottom of the Zip Lining.
Dave was looking forward to a weekend of Zip Lining in North Wales, but his jaw wasn't!
