it happens when you're in da middle of climax, (u have 2b on the top, otherwise it can not happen "pendejos")then when u r about to cum, take out ur cock, grab a lighter and make a fire on her hairy pussy, then u spit ur baby yoghurt to stop the fire and ur girl has to say OH SHIT!! U´RE MY FUCKIN HERO!!!
yesterday i was feeling a lil bit useless, so i call my sexpartner and we did the firefighter superhero, man! she was so fuckin proud of me!!
