It is, at the very least, a fear they share. Armin has no idea what he is doing. Or rather, he's gleaned a rough picture of how these things are supposed to happen -- from books, from bragging conversations many other trainees would have in the evening in the dorms, and from one enormously awkward conversation with Jean. But he also knows that of those various sources, only Jean can be somewhat depended on.

He is, as they say, flying fucking blind and he really hopes there are no trees ahead.

Armin's fingers dig a bit further into Angel's hips -- not painfully, not harshly, just a little more tightly. It's honestly a little intoxicating to be here like this, bathed in the warm glow of the heater, his mouth dragging along Angel's skin, while he can feel ever little shiver and shudder of her body. And spurred on by the way she is leaning into him --she wouldn't do that if she wasn't enjoying this, right?-- he takes it a little further, his kisses becoming more heated, his lips fasting down on her skin and giving it an experimental suck just like he had read described in countless of books.
