>>2572955It's the contrast of seeing someone who looks wholesome in some way, whether that be noble or kind and innocent, being fucked like a piece of meat on the next page. The position especially makes the person look like a fucktoy: we don't see their face or upper body as they're being fucked, just their hole being stretched and filled with cum like that's all they're worth now.
They've been reduced from being a cute/handsome wholesome well-meaning guy to a hole for some cock to ruin.
