Bah, why bother giving Marsha a good time? She can't stop you from swallowing her, can she?

Well, it seems she can. Since you are eating her hips first, she just "stands up straight" and she slips right out of your mouth. And she catches you at just the right moment when you are getting ready for the swallow that would have put her too deep in your throat to manage that little trick.

If you had been expecting this, a quick grab would have pulled her back into your mouth, probably to stay, but you are too startled, and she moves out of position before you can react.

For a moment you fear she is going to start eating you feet first, something you are going to have trouble stopping with the 2 girls in your belly slowing you down, but she may have other acts of revenge in mind.
