Undertale - In dreams you're mine all the time We're together in dreams, in dreams

For context the woman in this picture is not really Frisk or Chara but Asriels teacher. If you have read Dreemurr reborn, you will know that this takes place after Frisk has given Asriel their soul and now they share a body aka Piccolo/Nail or Yami Yugi dynamic. Thinking about his hot teacher makes Frisk take over.and "flirt". I know you can conclude everything by just reading the source but whatever.

Where is his hand going? WHERE IS HIS HAND GOING?
