I am not quite sure how aid another works with grapple (and especially not with vore). Does it increase the DC the guard have to pass to move it back a step by 2 (for each of the aids) or does it just give Khei a bonus on the swallow or does it give both of those things? This would most likely be a DM discression kind of thing.<br/><br/>In either case the guard is going into Khei's stomach whether she wants too or not. Even if she does manage to back out of the mouth she would still be stuck in Khei's grapple at which Khei would just swallow her down again. And with the other two pinning her to make her unable to effectively struggle, it's just a a matter of time before she vanishes never to be seen again (because I repsect the other's blocks xD ).
