Tim would call jon baby boy when he’s being all bratty. Jon talking back and Tim just rolling his eyes like “ooh yeah big tough guy, so scary. Cmon, let’s get you nice and full, alright?” Not taking it seriously at all. Not having to admit how badly he needs it makes it a lot easier. Grumbling into his shoulder as Tim coos “aw, cmere kid. There we go. Does that feel better?” As Jon stops being all whiny and starts trying to get him further inside, making cute little ah ah ah noises.
