Music Cues (with closet weeaboos!)

After a late night, Krista comes home to some great news. One thing leads to another and Ymir tries out something more romantic for the two. What starts off as a steamy session doesn't end as planned. Just lil ol' me peeking my head in the VAST VOID known as the yumikuri ship. AU cause that's all I do (yay moar rhyming) Futa!Ymir. Has most main characters & side ships. One-shot. :K
