Assuming you're not talking about the not even close to arousing cleavage...
Yeah, the first time I saw it, and the placement of the "sword" (yeah, it's a real sword, but I felt the need to quote), it made me think the sword was a stand-in for something else.
But it's at least pointed towards her throat/chest, as if prepared to kill her, as opposed to the absolutely "not really a sword" symbolism if it were at say...mouth level. I just found it funny, and wonderd if that was on purpose, or unintentionally hilarious.
You forgot to mention that princess's facial expression. Instead of being scared or worried, it comes off as a vacant pouty "I'm forced to do porn to pay off my student loans, so I'll halfass it since I feel ashamed of myself." Then again, it would have been totally wrong if she had a satisfied or a surpised "your 'sword' is huge!" look on her face.
