Gotta admit, I do feel a bit sorry for Shion, having to put up with teenage Asuna. My siblings were never that bad, thankfully.

Shion had better get to engaging in all the childish, monkey-like physical shenanigans she can for now.... as when puberty hits, she'll be going through new bra sizes on a daily basis...

(yeah I'm talking about the chapter before)As a man, I've never heard of an underwear that has a hole for your pen** but I've heard of an underwear that has a specific net like part that is made for your balls...
That doesn't bother me today but damn did it bother me so much in puberty, I just can't seem to get comfy with my undies...
