If anything it looks like they're sucking on them for milk.
I'd say that doesn't make sense, but let's face it. They're already sucking on detachable breasts from someone who had a genderswap forced on them to comply with Haruhi's worldview. In comparison to that this is almost normal.
I would say that Mikuru is a somewhat special case. She still looks mostly the same, she just has her detachable breasts and apparently a giant dick.
Koizumi is obviously fully swapped, as is Kyonko. Mikuru seems to be somewhere in the middle. As such though I'd err towards just keeping it as a simple Mikuru tag, rather than Mitsuru or whatever the genderswaps name is.
Agreed ELPysCongroo, I am actually better entertained by Shun' work than the actual series lol.
