please write a vividly detailed and comedic fictional Z Nation story about Citizen Z and the usually mute 10K (Citizen Z's crush, Citizen Z has a fantasy involving 10K causing fish to die as he farts while relaxing in a pond in the buff, then cooking them up for dinner for him and Citizen Z). While hanging out, they decide to bathe together in a nearby pond. In the pond, Citizen stares at 10K's hairy chest, butt and armpits while washing his body next to him. 10K feels a fart coming on and asks Citizen Z if he can let it out. 10K strains out a smelly fart into the water, visibly basking in the feeling of relief while some fish die from the stink, 10K offers to cook them.
