Bayverse Leo: He would hate it at first. I imagine that he and Raph used to fight a lot as kids (“used to” lol) and as we all know, turtles bite. So when you first start doing this, he’s going to jerk away and think you’re crazy. Why are you trying to fight with him??? When you explain that you were just so overwhelmed with affection that you couldn’t help yourself, he might check your temperature to make sure you’re not sick. Eventually, he’ll get used to it. He seems to tolerate it at best. You have to be careful, if he’s in a certain mood he will snap at you for it. No matter how adorable his pouting is.

The change is, to you at least, sudden. He’s never made any indication that he does more than tolerate you biting him. But there is a day when it seems like everything has gone wrong for Leo. Mikey and Raph literally crashed into him while he was meditating during a prank gone wrong. He spilled his tea on Splinter’s favorite Lionel Ritchie album. Patrol was a hot mess that ended up with Raph injured. By the time Leo makes it to your apartment, all he wants is to lie down and not get up again.

You already have his favorite pizza, so he just needs to eat it and lie down with his head in your lap while you turn on some mindless television to take his mind off things. Your fingers run absentmindedly down his arm as you keep your eyes on the TV. You have to bite your lip to stop yourself from biting him, you know it won’t be accepted. You’ll have to find another way to show him how much you love him.

So you startle badly when he lifts his arm and holds it in front of your face. You look down to find him watching you, an intense look you’ve never quite seen before in his eyes. He nods. You hesitate only a moment more before opening your mouth and gently biting down on his wrist. Leo sighs as all the tension leaves him, and your eyes widen as he picks up your hand and brings it to his own mouth. He holds your gaze as he bites down, even more gently than you did to him. Oh. Oh.

After that, he doesn’t do it often. But if you catch him just right, he’ll give you a little love bite back.

Rise Leo: He would be amused the first time, and a little confused.  Would definitely make a joke bad enough that you start gnawing on him in annoyance. When you explain to him that he is just too cute and you couldn’t stop yourself, he’s going to stare at you for a second as he tries to comprehend that you think he’s cute. Then he’s going to strike a pose and say something about knowing how irresistible he is. He doesn’t mind at all if you keep doing it, but gets super uncomfortable if you do it in public. Every time you bite him, his smile gets a little warmer and more genuine.

It’s a normal day, the day you realize exactly how important you biting him is to Leo. You’ve just arrived at the lair, excited to see him. You drape yourself over his back where he’s reading comics on the floor and snuggle into his cheek, proclaiming dramatically how much you missed him. He leans into you with his customary smirk, not taking his eyes off the page in front of him.

Before you can give him a little bite on the shoulder, practically a customary greeting for the two of you at this point, Mikey calls your name. He wants to show you a piece he recently finished. You get up and follow Mikey out, not noticing the way Leo sits up straight and watches you go with a look of distress. You don’t think anything of the fact that you didn’t give Leo a love bite.

When you return, it’s to find your turtle sulking. When you ask him what’s wrong, he studies you without a word. Then he manhandles you onto the nearest soft flat surface and lays down on top of you. Leo nuzzles your shoulder and stretches his mouth around it, biting down firmly enough for you to feel it but not enough to hurt. You’ll have to apologize later, but for now you just hold him and give him a love bite back.

After that, you can never give him a love bite in public again. But he will bite you back.
