Please and thank you? Yes, Su-jin most definitely heard it. The perks of being an apex predator with heightened senses. He can also hear so much of what's going on just beyond their door. He's had time to get used to that keen hearing, time to learn to focus and not let it become a distraction.

It's hard to be distracted with such a large presence before him. Vena's aura fills up all the available space, commanding attention without any effort on his part. The scent of him... Su-jin's sure he'll learn it and learn how to keep it from overpowering his thoughts. Despite that vast presence, he's small and light astride Su-jin's legs. Unlike the sort of men Su-jin's fantasized about it. Vena hardly has the shape or (apparent) strength of the laborers working in the fields. But he is irrationally beautiful. It's easy for Su-jin to see how weaker-willed creatures would fall under Vena's spell in an instant.

He's tentative, but Su-jin once more brings his hands to Vena's waist. It seems a safe and comfortable way to touch the older monster. They linger a moment before slowly creeping up the incubus' sides. It's as bold as Su-jin feels he can muster without more guidance.
