She spotted the infected ears first, those swollen gray-blue pustules bursting out of the corn kernels like dirty secrets. "This is edible," she said, yanking one off the stalk. "Corn smut. People pay top dollar for this shit in fancy restaurants." I watched her bite into it raw, juice running down her chin.

It tasted earthy, mushroomy, with a hint of sweet corn. She grinned at me, mouth full. "Bet it would taste better licked off your cock."
We didn't make it back to the house. She dropped to her knees right there in the field, unzipped me, and smeared a handful of the soft, slippery smut along my shaft. Her tongue followed, licking the fungal mess clean in long, greedy strokes. "Fuck, it's so slick," she muttered, spitting on my head and mixing it with the corn smut. She sucked hard, cheeks hollowing, while her fingers worked the rest of the ear between her own legs, rubbing the creamy insides against her clit.
I pulled her up, bent her over the wooden fence post, and yanked her shorts down. Her pussy was already wet, but I pushed a glob of corn smut inside her anyway, fingers pumping it deep so it coated her walls. She moaned loud when I replaced my fingers with my cock, sliding in easy because that smut made everything filthy and lubricated. "Deeper, you bastard. Stuff me with it." I fucked her rough, hips slapping, the wet sounds loud in the open air as the smut squelched out around my shaft with every thrust.
She reached back, grabbed another ear, and shoved pieces of it into her mouth while I pounded her. "Eat it," I growled, "then kiss me." She turned her head and we swapped the half-chewed smut between our tongues, tasting each other and the fungus at the same time. I reached around and rubbed her clit with more of the stuff, making her jerk and come hard, pussy clamping down so tight I had to slow down or blow right there.
We switched positions. She climbed on top, straddling me on the grass, and lowered herself onto my cock again. This time she took her time, rolling her hips in dirty circles while she fed me bites of corn smut from her fingers. "Suck it off," she ordered. I did, licking between her knuckles, then she leaned down so her tits hung in my face. I smeared smut across her nipples and sucked them clean, biting just hard enough to make her swear.
She came again when I sat up and fucked upward into her, one hand fisted in her hair, the other shoving more smut between us so it smeared across her belly and down to where we were joined. "Fill me up," she begged. I did, pumping thick ropes inside her until it mixed with the smut and leaked out around my cock. She stayed seated on me, grinding through the aftershocks, then scooped some of the mess with her fingers and licked them clean while staring me in the eye.
We stayed out there until the sun dropped, using up every infected ear we could find. By the end she was covered in it, streaks on her thighs, her tits, her mouth. I was the same. We didn't bother cleaning up before heading back. The corn smut had done its job, turning a simple farm chore into the dirtiest, slickest fuck either of us had ever had. She already planned to can some for later. "Next time," she said, "we're doing it in the kitchen with the whole jar."
