Well as i am predominately straight i have a very precise fantasy, hear goes, everything has been pre arranged, i shower, shave ! and dress in a special pair of rear zip jeans and a white tee shirt, it is a warm summers evening, i drive to a local dogging spot and park up, open my bonnet and lean over the engine as if trying to fix it, prior to this i have unzipped and lubed up my bum in anticipation of the forth coming events, excuse the pun, then i hear the sound of an engine, the van pulled up behind me and the side door opens, still leaning over the car i hear a voice say "whats up mate" the pre arranged key words, i take a deep breath and utter my arranged reply "nothing yet , waiting for some oil " i can hear some muffled voices and some commotion behind me but don,t look around, not a clue how many people were there. The next thing i felt was my back zipper being pulled down and a finger inserted into my slippery ass, followed by the words " right lads who,s first " then with a hand on each of my hips the first guy plunged his cock deep inside me and started thrusting slowly then faster and faster digging his fingers into my hips, then he stopped and jerked as ha came in me and pulled out, i could feel the warmth of his sperm running down over my balls. then before i could regain my composure he was replaced by another and another, i think i counted 14 in my somewhat dazed state, i cad a cocktail of spunk running from my ass all over my balls and down my legs, i had also come 3 or 4 times all over my car. I hear the voice again "cheers mate" and the van drive off, i quickly zip up and stagger to the car after shutting the bonnet,get in and drive home while sat in a massive pool of semen still running from my bum, .never knew any of them or heard from the contact that set it up ever again.
