So, one thing about Ryuko that I wanted to bring into this answer is how flustered she sometimes gets around sexuality and nudity. I don’t think she’s a prude or anything, but she seems like she can get easily embarrassed, and I like the idea of a more confident girl like Satsuki being able to push her buttons just right to gain the upper hand in a sexual encounter. Every time I’ve drawn these two before it’s been Ryuko chowing down on some Satsuki butt, which she seems to enjoy (and who can blame her), but I wanted to show a different wrinkle here. Ryuko’s not being, like, a BDSM sub here or anything, but she’s definitely taken a more submissive/receptive role now that Satsuki’s decided she wants a taste. 😉
