In another situation, with more time, that might be something to explore. But this is still too new and Suguru is too cautious about it, so she does as requested and stops touching her clit directly, teasing her lips instead. That's not her ultimate goal, of course, but it's fun to get her aroused before doing anything more.

"How do you get off, Satoru?" That's not something they ever discussed when they were teenagers. If it weren't for the fact that Satoru regularly dated guys, Suguru would have assumed she didn't bother with anything remotely close to masturbation. (And perhaps she didn't; perhaps the men were all she needed.)

Suguru trails her hand lower, fingers teasing the rim to her entrance, and then she sinks in two fingers.
