Madoka is the kind of girl who just keeps on going despite someone being in the room.

I think she is doing it specifically cause someone is in the room

I was under the impression that Madoka is asking for a Moemura X Madoka X Mami threesome, in that order. I'm flabbergested on Moemura on top of Madoka, let alone Mami.
