cowkuna looking down on the newly brought in bull yuji because he thinks the brat is smaller than him, tiny in comparison and can't possibly satisfy him even if he dares do all the work. he's always such a bitch about it that when their farmer decided to make the two mate each other, cowkuna's mind is just melted and gone. yuji's cock is just massive(way bigger than any other cocks in the farm) and since then sukuna refuses to mate with any other bulls. he's willing to risk his ability to walk because mating with yuji means having his womb utterly demolished and he can't move for shit on days end.
