There is an option at the end for you to stick your head in his mouth. And this sets up for a future scene with Trald at the Police Station, which isn't in the game yet. Basically, when the followup scene is added in, it will either be another sex scene if that's all you did in the first one or a full-on vore scene if that's what you teased Trald with in that DoR scene.
But, again, it's not in the game yet and likely won't be until the Police Station itself is.
