Ensnare her with vines

You decide to take a gamble, and using your knowledge of the dream realm, you manifest vines which sprout forth from the ground, wrapping themselves around the female until her legs and arts are fully restrained.

"Hey! What they hell is going on?!" she exclaims.

"Shhh its ok, this is just a dream; you really expect me to believe you never dream of being dominated like this?"

You have no clue how she will respond, but you're willing to hedge your bets on her having a hiding submissive side to her.

"If you don't like it, you can wake up at any time.." you add. At this she looks up at you with pleading eyes. "No!.. Please.. fuck me..." she whispers quietly.
