That’s how it should be. A master’s seed comes from the depths of his soul and it is the sub’s job to keep it inside of herself, inside her womb safe and sound, protected where it will be put into good use and replenished whenever needed. As someone who has been a with partners who have had breeding fetishes like mine, all I can tell you is, that cum belongs only on one place. Inside the body. On the face, tits, ass, back, works, but it’s a waste. Down the throat or inside the womb. Those are the most beneficial.
