This situation is really strange. The side her lower half is on is the elf side, so there isn't actually any chance of her being molested by an orc. Not her backside anyway.
Of course she broke the wall herself. Look at the second panel lol.
I think the question is more in how she got through the hole with those giant melons of hers
Ah... a defenseless elf's elf......A sexual prank on my bottom half!...but I got stuck instead!Aah, whatever shall I do... I was trying to pass through this wall......is going to be teased by an orc's orc!At this rate, someone's going to take advantage of my immobility and play a prank on me...*Glance**Glance*
