Sekibanki is the master surpriser- she's more suited for it anyway.. I just hope she doesn't share the sensations with all those heads at the same time.

It's not like I know much Japanese or anything, but I think it's a play on how she's blushing. Sekimen, meaning blush (translated as red face in the title, which I guess could also be "Sekibanki does/will not blush" or ), is used as part of what the kid calls her, Sekimenki, which sounds similar to Sekibanki. So it's just some Japanese wordplay.

Sorry for the scuffed explanation, there might be something deeper, but I've only really taken one real Japanese class, besides a couple years of self study.
