Yes, a key part of it

The 'heat' between your legs is almost intolerable, but you're still less than enthusiastic about letting an old pervert stick his dick between them.

When does the plan kick in?? You resort to directly asking your head's co-inhabitant, nervousness clearly audible in your 'voice'.

The moment he spills his seed, he'll be ****. I'll take over then. You manage to sputter despite communicating telepathically, but before you can protest about the plan, a mix of pleasure and pain wracks you suddenly.

Oh, fuck. That old bastard just shoved his cock into you. It didn't look out of the ordinary in size, but right now you feel like you're being split in half by a tree trunk...being deflowered so suddenly should be a painful and completely unpleasant experience, but the old wizard was more than liberal with the clearly magical aphrodisiac, and the feeling of having your freshly acquired slit invaded is incomparably pleasurable.

You feel Dennis' hands roving about on your body as he thrusts into you, his breathing ragged from arousal. Your brain tells you getting felt up by an old geezer should be less than enjoyable, but you can't hold back a moan as your nipples are fondled through your dress...everything is just so sensitive, and it feels so good being touched.

Before long, the old wizard's found his rhythm, and despite an inner kernel of revulsion at the whole situation, you find yourself moaning in pleasure, your female voice unrecognizable to you.
