[Hayake] Bokujou no Oshigoto (Nani Suru no!? Onii-chan!!)

After a year of failed job hunting leaves Kenji desperate, his uncle offers him work at the family ranch, where his energetic young cousin Mari drags him through every chore from hauling milk cans to tending the pigs. What starts as innocent instruction gets increasingly hands-on in the barn, until the two end up tangled in the hay, her small overalls stripped off and her flushed body pinned beneath him while a curious pig wanders close. By the time the warm mess he left inside her is dripping down her thighs, Mari is already cheerfully asking her onii-chan to come back for tomorrow's 'breeding job.'
