You're Legensuia

Well, at the end of a day you end up helping Mothra again take care of her son and everything... Now it's evening and you were on the couch having a brief conversation with her before leaving, her son, Leo sleeping in her bed, Mothra is now only wearing a white robe and with it half open between her breasts and showing her thighs and legs, and with that, Mothra says looking at you with a soft smile on her face and a grateful tone of voice

Mothra: As always, thank you, Legensuia, for the help you always provide me with taking care of Leo... You don't know how grateful I am to you for always helping me...
