I took a bit long because of the redraws.
Also, the word I translated as "horny" is エロい and it's a term a bit ambiguous in JP. I looked at the official, but they translated it as "steamy" in a previous chapter, which doesn't fit this context (no one says "I'm feeling steamy"). Here エロい気持ち means "feeling aroused".
If you see any error, feel free to point them, cause it's a bit rushed.
Edit: I read that some people think "horny" is too direct, too raunchy, too juvenile or whatever, but what Saki says really boils down to that.
I mulled over it for a while, but I couldn't think of a better way to express that it gave her "dirty feelings". There are other terms, like "aroused", "erotic", "a turn on", "hot and bothered", for エロい気持ち. In the end, I decided to keep it short and punchy. In Japanese it's a bit euphemistic, but that's how Japanese works. In English, it's better to be direct.
