Just found this one recently. Started off choosing to spy on Nikki and got the outrageously catastrophic bad end. Knew immediately this was gonna be a good ride. Actually laughed out loud at least twice.
My theory is that they will realise people won't accept their relationship
That would require them to encounter people that actually don't accept their relationship. Sarah strongly encourages them and approves if Tales answer Nikki during Truth or Dare; Molly, who is also present during the game makes no objection to anything they do up to and including Tales answering Nikki as which of the three he'd like to fuck; Mrs. S gets Nikki to give Tales a bj; and Jessica was pretty into that threesome with them, and remarks that she likes that despite their arguments they are VERY close.
Their mom might object, though. She was pretty upset just about Mrs. S banging Tales.
