Do as you're told and lie on the bed

{if Slave to cock == true}The prince's cock is fully visible, so you find that you have no choice but to obey{else}As horrendous as this will be, you sense that nothing good will come of refusing a direct order from this man{endif}. Slightly shaking, you walk slowly up to the mattress, and mount the bed. When you lie down, you make sure to find a spot that's not currently soiled with sperm and other sex fluids.

You can't bring yourself to look your mother in the eye.

"Go on slut, get on top." The prince snarls at the Lady Marisa.

She whimpers with shame and reluctance, but immediately obeys, squatting over your face in a sort-of lesbian 69, but without actually touching you skin-on-skin.

Still, despite her best attempts not to make this actually incestuous, there's no doubt that what happens next is not only disgusting, but entirely inappropriate for a mother and daughter to experience together. With your mother's posture in this squatting position, her pussy opens wide, and this, combined with a bit of help from gravity, causes a surge of sperm to spurt forth from her folds, and plaster your very unamused face.
