According to your plan.

The first part went as you planned and now that Isabella is definitely exhausted , it's time for you to start with the second part of your plan:

Now it’s you who’s moving and you keep fucking Isabella’s tight pussy from behind with almost the same rhythm she was doing, not slow but far away from a hardcore fuck. Last night you thought about how many mans have fucked Isabella's pussy in the exactly same way that you did, and knowing that she was a fuck-toy for years she probably have been also fucked in her pussy so many times from behind like you are doing now. They probably weren’t as educated and respectful as you are now, but this is going to change soon.

When you thought about this plan one of the keys to make it viable was that you knew a fact: Isabella loves being dominated and used by mans like she has been almost half of her life. That was the reason she conviced Marian to fake that they were under your magic, Marian probably disliked it because she seems to be lesbian and not bisexual, you are not really sure but it doesn't matter anyway.

Keeping this in your mind you slowly start to go harder on her womanhood, and most important: your hands leave the back of Isabella’s hips and with the right one you grab both of her hands on her back while with your left hand you begin to pull her short hair making Isabella scream, the only words you recognice are “YES” and “MORE” so she's probably used to be fucked this hard or maybe harder.

You could end now what you've planned and you probably should, you check one of your pockets to confirm that you could actually end this but you want to see how far you can go, and most important: you are enjoying so much dominating Isabella. You stop fucking her cunt form a moment to push Isabella to the ground as you hear her saying:

“I’m glad that you like it really rough”

Your only thought is:“You haven’t seen anything yet”

Instead of the classic doggystyle pose you still have both of her hands locked behind her. You don’t pull Isabella’s hair anymore and you let her head fall to the ground while keeping her hips up so start fucking her asshole.

She's head down and ass up while having her ass being pundered by your massive cock and you are still amazed about how can Isabella love being fucked in this way. She tries to look back and it bothers you so you move your right leg to end up with your foot on her head, pushing her face even more down and probably hurting her.

And when you realize that she's still enjoying this you give up: you don't really understand how can most of the womans love being absolutely owned in sex, maybe is a correlationary fact just as how most mans enjoy dominating womans in sex, who knows.

Anyway this has to end, so you wait until she's ready to reach the climax and when you feel that she's about to have the orgasm you stop fucking her ass. And this time after cheking your pocket you take the item that was inside it and quickly handcuff both os her hands that were still on her back before she couldn't understands what's happening and how this isn't part of the sex anymore.

You had this handcuffs for a special chance and you are glad that you brought it in your travel to save Bethany, you were not thinking about using the handcuffs in this way but it helped you anyway. You walk around to be in front of the powerless Isabella. Time for you to decide her punishment.
