Who is タッグ? I can translate the rest, just don't know who that is.

It's tag (the game). This comic is a continuation of post #360071

Hrm. Even knowing what it is, the first line doesn't entirely make sense. Sad, but I've left this one and the previous one about 90% translated...

Tag, as in wrestling. In the beginning of the other comic, Alice sees herself and Marisa as wrestlers.

Next is post #317439, and there are probably more.

Yeah, I figured it was tag team wrestling. But 'tag wo kunda wake?' doesn't make much sense to me. She hasn't paired with anyone.

:o
Marisa you WHORE!
