"This is troubling news." Ningguang says with concern, "I will put someone on the case immediately."
"I am sorry... If I were more careful, I wouldn't get corrupted by the Abyss power." Ganyu sulks.
"Hey, Traveler, didn't you purify Dwalin's tears back in Mondstadt? Why don't you try the same with Ganyu?" Paimon chimes in.
You walk up to Ganyu and place a hand on her forehead. You feel the same energy as the one that befouled Dwalin's tears, but the tears were small, and you could cleanse them fully - Ganyu's body is much larger and you can't reach deep enough to fully expunge the corruption.
"Didn't work, eh? Guess it is impossible to do on something larger." Paimon explains.
"Not necessary impossible. We don't have much time, so there is no other choice." Ningguang says "You must perform a sexual intercourse. Then you can purify Ganyu fully from within."
"But..." Ganyu gasps. She looks at you and her face turns red.
"Use one of the Jade Chamber's bedrooms. You won't be disturbed." Ningguang says and leaves you two, dragging Paimon away by her leg.
"T-traveler, please don't stare so much." Ganyu says bashfully as you ogle her body from behind.
"I am going to work that ass overtime." you tell her.
"What do you mean?" she asks in a worried tone.
"I mean that I will pound your sexy rump until I pass out." you take her skin-tight bodysuit off, and she now stands naked in front of you, fidgeting.
"No, Traveler, please don't say things like that... that's too embarrassing..." she covers her increasingly red face in shame.
"It's your fault for having such a thicc sexy ass." you grab her by the waist from behind and press your raging hot erection to her soft plump buttocks, "I am going to keep coming inside you again and again. I'll fill you with so much of my seed, you will have triplets."
"No, please, traveler, you can't do this. What about my work for Qixing." Ganyu objects, but you can see her getting wetter by the second from hearing your words.
"You will have to take maternity leave to feed by children with your cocomilk." you push your engorged rod inside her and, holding Ganyu by her waist, start pounding her from behind relentlessly.
