Magnus soft-domming the ‘favorite serf’ would mean:
A lot of compliments, “You’re taking me so well!/Your Primarch will be pleased!/I might steal you away from him if you keep feeling this good.”
Patience, “We can go slower if you’d like./Does this hurt?/Deep breaths, you’ll get it.”
Asking what you like in bed, “Tell me where I can touch you?/Guide my hand, little serf/Should I go faster for you?”
Copious amounts of lube
