Not at all

The Grimm quietly brings its tentacles towards the blond, without even alerting her.

As she simply floats on her back, this allows Tentacles to untie the knot on the back of her top, when it came undone, it slowly remove the top revealing Yang's majestic breast.

And then after the top is removed and taken underwater, it then goes for the bottom in similar way.

Now, Yang is finally left with just her accessories as she drift on the water naked.

The Grimm then simply dove back into the deep water, waiting too see the reaction from the blond, as it took the swimsuit as another part of its collection.
