The first part of the Mummy Girls Game Over has the party being trussed up by the Mummy Girls. Seems each of them is getting different treatment based on how they were perceived.

Part 2 has everyone engaging in various yuri activities (or post activities) in a room filled with sweet smelling incense that has everyone in a lewd frenzy!
Part 3 has Mira utilizing the power of the incense to bust free of her bindings and instead use her own magic to take control over everyone in the room. She quickly wraps up everyone involved in the festivities and begins to change the mummy girl's thoughts into worshiping her instead.
Part 4 has Mira relaxing in a bath after completely taking over the Mummy Girls and is controlling them to pamper her. Selena is hanging out with some of the more troublesome Mummy Girls and Hemmy is just happy to be hanging out in the tomb as a Guardian again.
Part 5 has Mira lounging around as the Mummy Girls under her control bringing the last of the Desert Bandits as they tried retrieving Mira from her family's tomb. She remarks that the others she send previously have made great play things and how they'll soon be joining them.
