After Saki and the MC find out the Shiki was spying on them have sex, Saki starts groping her and invites her to join them for a threesome.

When talking about Shiki joining, Saki contemplates how the MC having sex with her would be cheating, but she also wants to see Shiki lose her mind with pleasure.
