SciTwi Doms Celestia (Patreon)

Sci-Twi dominating principal Celestia is a pairing I don't see often enough. Especially when Celestia seems to be the only one worried about getting caught, it almost seems like Twilight wants her teacher's moans to arouse suspicion.

(I guess some people avoid it because of real-life badness, which is fair enough, but I don't have an issue when it's just a fantasy.)
