The hand on his dick, keeping up the same pace as the way Sephiroth fucked him, rough and quick - that might have been plenty on its own, given a minute. Zechs writhed a little, shaking his head while he tried to keep himself contained. It's raw sensation -

Yet getting into Zechs' head was always the clearest way to strike him where he was weak.

The fingers around his neck already wrested a small, surprised sound from him. Not a hint of pressure, but a vague sort of threat - perhaps it's embarrassing Zechs broke a little for that, yet there they were. But what Sephiroth did after was better worse better still - forcing his chin up. Making him keep his gaze, right there. Maintain eye contact. Watch Sephiroth watch him.

See that competitive flame in his eyes, the hunger, the desire to watch Zechs fall apart. Watched how they glowed faintly in the darkness. Watch the satisfaction seep in as Zechs shuddered, moaning as Sephiroth still fucked him hard -

Loudly moaning, cursing, just - and he's still looking, looking as he fell to pieces on his dick, as he lost all of his control - he's mostly incomprehensible, but there's some coherent words such as - "Fuck, Sephiroth, you -"
