Cute Gone Wrong

I love looking at fanart, and sometimes even buying it. But this drawing, while drawn well, looks... off.

It's Buffy and Spike as ponies. And is it just me or does it looks like Buffy's raping Spike? The position they're in, her determined/cruel expression and Spike's helpless expression, all which could be a unintentional mix, makes it look bad. If Buffy's been standing on him, I think it would work better.
