Grimlock ♥ Ultra Magnus

Well written, with a somewhat realistic reaction from the protagonist.  

The grammar is pretty good, too, with this exception: "...the new tentacles more impatient and rough than the first ones..."

The attempt at consistency is nice, as it's clearly supposed to read, 'more impatient and more rough.'

It read weird to me, though.   Rougher would be the correct word here.   

Anyway, it's still porn, and didn't really have me connecting with it at all.   Not emotionally, not in a 'oh, it's hot' type way, so I knocked off two stars because I read for both good writing and an emotional connection.  

Still, one of the better monster porn shorts I've read!
