For a split second during one of the HoloMyth off-collab videos (I believe it was the arm-wrestling one), Ina's model glitched and revealed her backside. https://www.youtube.com/watch?v=8FLtCUROlCg
Honestly, part of it was also probably that the Takodachis were backed up from about a month of not seeing Ina streaming. Ina has since claimed that it was just the shadows cast by the wings on her skirt, but that barely slowed down the flood.
Yeah this totally tracks. We know Mercedes likes girls cause she’s a gay romance option for the player, but there’s not really any indication that Annette like girls at all, so this is probably what their relationship is actually like.
