I have a recurring fantasy where im meeting a guy in woods somewhere, and i give him a blow job, as im doing so there are around 5 other guys stand watching us, all wanking nice big cocks.
As the guy i met originally is about to cum, i stand up, pull the waistband of my trackies open, and allow him to cum over my cock inside my trousers, and then allow the other guys to do the same.
Then we all go our seperate ways without saying a word, and me with my pants full of 6 guys cum.
