Thankfully for Caspar, Rose doesn't mind too much. The rush of breath and hum of his voice tickles more than anything so she actually gives a small giggle.

Oh, that's interesting. Rose can't actually say she's done much "experimenting" on herself in this way. At least, not since arriving in Erku... Perhaps she's gotten a bit spoiled in terms of having partners who please. And it's fun, in a way, to think she might be helping Caspar become one eventually. "A-ah-" she lets out, in a sigh.

"Good. Now, faster."
