Financially Dominated Mashochist Hero

In obedience to an imperial order, you are going deep in a dungeon.
When doors of the demon lord's room come into your sight, a girl appears.
This is the beginning of mishap. Your magic will be taken away and,
opposite to your initial purpose to defeat the demon lord, some lewd
magic spells will be instilled in your head for making use of your power.
Is there any way you could resist her destructively pleasuring honeyd*cking?

A voice drama with strong emphases on reverse NTR (cuckoldry) and verbal ab*ses.
