I don’t think it really matter in that world I mean if you read the one with the bunny and wolf by the same author they are fucking and so is everyone at the school, it’s like nothing to them. I don’t like how the lion guy accepted it he should have just got out of there, I hope he didn’t continue his immoral behavior like that I rather him and the horse be like first timer together or what ever but I know that won’t happen
It can also be due to the influence of his 'heat'. It can cloud their minds like in other stories with this type of trope. So his decision-making was probably not fully at his control in sense due to his hormonal phase, the teacher trying to convince him-clouding his judgement, as well as his young age. Im guessing they were in middle school, since present time is in highschool. At that age, teens still havent yet grasped the understanding of actions and consequences

He is a minor you fucktard and stop being a horny bum
