Nick, don't be ridiculous. It was clear what Mashima's intentions were for the scene. And this is far from the first time that he's stripped down a female character at inappropriate times. Can a naked women be added without their being fanservice involved? Yes. Is it likely with Mashima? Hell no! One or two naked women, sure. But Mashima has them constantly throughout his manga, and if he truly is such a terrible writer that the only way he can show how, what was the word you used, "desperate," a situation is, is to strip a woman's clothes off, then he should be ashamed.

The fact that the tentacle monster was there and didn't touch Erza is exactly what proves that the moment was useless fanservice. What purpose did the beast serve, honestly? Erza was beaten and tortured and was completely unable to use any Magic. Do you honestly think that Kyouka thought she was going to escape? No. Mashima put the monster there as a reference to tentacle rape.
