[His stung pride is soothed by that admittance it wasn't his fault (because it wasn't, and he wants to be very clear on that point), and it makes the next part a lot easier. Something in Fenris relaxes as he wrinkles his nose.]

I don't. It was just . . . she just sort of . . . happened.

So you think he is jealous because I got there first. Like he wouldn't be crowing about it for a month if he had, calling me virginal and telling me I didn't know what I was doing— and I was only kissing him because he didn't want to look like an idiot in front of his teacher!

[Evidence somewhat indignantly presented, for Astarion has rubbed off on Fenris in any number of ways.]

If anything, he should've been thanking me. He wasn't even that good at it . . .

[Oh, that's not true at all.]
