Raphael is a solid no. he doesn't wanna put anything up his ass, and really just doesn't find it arousing.
Donatello wouldn't be up for it either, but that doesn't mean he isn't partial to butt plugs. He knows the prostate can be a very good source of pleasure, but he doesn't like the feel of the dildo slipping in and out of him. So it's a no.
Leo is someone you would honestly have to beg and beg and beg for to try it on. He's very dominant in his stance when you two are in bed, so when you ask for pegging, he's not jumping on the band wagon immediately. And if you do manage to convince him, you have to be good at what you do. Chances are, if you know what you're doing, you can have him moaning and shaking under you after cumming for the third time because that ass is sensitive haha who knew.
Mikey would be up for a lot of things. He may not be thinking of trying pegging, but he wouldn't refuse it out of the blue. He's up for trying new things. Pegging isn't his total fave, but he'd be lying if he hasn't came a couple times from his bae's work on him. He does have a thing for love eggs and vibrators being used.
