Mike did indeed find that his massive new size and strength made it much easier for him to plough the farmer's fields. Every morning, before the sun was up, Nia would bring him food and water for breakfast. He wolfed down every crumb she offered, knowing that he would need the energy. When he was done, he hoisted the plough over his broad shoulders, and marched to the fields, to do the drunken farmer's work. Sometimes, Nia would pat his muscular rump as he left the barn. She would come to him again at noon, to bring him lunch. If her father was very drunk at midday, she might order Mike to provide a noontime quickie as well. Mike would then return to his duties, ploughing the tough earth, until dusk fell. He'd lift the heavy plough, and carry it to the barn, where Nia would bring him his supper. Once her father was safely asleep, she would return, and Mike would fuck her slutty farmgirl brains out.
This routine became Mike's life: eating, sleeping, working, and fucking Nia at every moment in between. Days became weeks, and Mike settled into his routine, realizing that his companions could not find him, if they were looking at all.
