[Tristan's actually a little calmer now. Because this is happening no matter what he says or does or begs, so the firm certainty in it is a little steadying. It's not pleasant and he hates it and he still feels gross, but he's not fighting it because there's no point.]

[Unfortunately that last word ends in a hiss, sharp. It's bad enough having his brother's fingers inside him, but he didn't know it could feel like that, that jolt of pleasure, and even if anatomy is his brother's interest why does he know how to look for that. He turns his face to hide the expression of conflicted pleasure and revulsion, trying to breathe carefully to keep from moaning like a whore. Despite himself his hips twitch, not to squirm away but because it feels good, rocking once between the hand on his erection and the fingers inside him, and he clenches his jaw, feeling debased.]
