Pretend to submit to the hypnosis, then stay awake to watch Sumin...

"He he he... You're not nodding, but I can tell from that little string of drool that you picked yes. Bon voyage-gee, Katappashikara!" she giggled... you pretended to shut your eyes, then, once she'd stood up and turned away, opened one a bit to peek instead. After all, you felt like you owed it to Keiko not to let Sumin do anything weird to her... Plus, it could be an interesting watch.

Watching Keiko, Sumin bit her lip and eagerly began to strip off her pajamas. Of course, you two had destroyed her underwear earlier, so she was completely nude underneath... you once again feasted your eyes upon the glorious fullness of her round, pale bottom, like a splendid full moon. Her breasts were heavier than Keiko's, the nipples an oasis of pink against all that whiteness. Her pussy was shaven; perhaps Sopor had thought that important for some advertisement purpose. Whatever the case, she had the look of a hot goth girl and the brains of an airhead... a strange priestess, that was for sure.

Right now, thinking she was the only person awake in the room, she seemed to struggle, reaching out towards Keiko's robe, then retracting her hands, then turning to you (causing you to quickly close your eyes to keep the pretend situation going). She alternated these motions again and again, trying to decide if she wanted to go through with messing with Keiko or not. Finally, she settled on a different course of action... she pressed one hand to the round, sizable cup of her breast and stuck the other between her legs, then began jostling both furiously. The girl was a practiced artist of masturbation and you respected the speed at which she was trying to achieve her goal.

Of course, she wasn't alone in the room and wasn't the only person interested in masturbating either. With her naked form in front of you, you couldn't resist any more; you whipped out your own godhood and began stroking it with one hand, focusing on the lewdly jiggling surface of Sumin's ass before you.

Ridiculously, the girl began to roleplay. "Sumin-san, you were very honorable when you decided to fight me blade to blade. I found you very arousing in that moment, much more so than my own god," she spoke in a voice that sounded way too butch to be Keiko's.

"Oh, Keiko! I know we've only just met, but I can sense that you're a great priestess!" she spoke in her own voice, becoming more heavily riddled with gasps as she sped up her rubbing.

She teased one of her nipples and even bent her head, sucking on the tip for a moment before continuing. "Your body is tasty, Sumin-san. You're like a... a... some... good... Japanese dish she'd know~" Sumin panted ridiculously, now sitting down and dropping to her back, sticking both legs in the air as she continued. "Sumin-san, do you like this position?"

"Kyaaa, no, this position's embarrassiiiiing!" Sumin squealed, despite having just laid herself down into it. You could see Keiko's eyes beginning to twitch awake and wondered if you should warn Sumin... instead, you kept watching. "Keiko, I want us to come togetheeer~"

"No problem, Sumin-san. I have become very aroused-and-and-and-!" she moaned, finally dropping the act as she squirted powerfully, her legs twitching in the air and her black, bob-cut hair nestling into the carpet beneath her as she threw her head back.

Keiko finally struggled awake, thanks to droplets of moisture splashing at her feet. She blinked a few times, then grew red-faced and jumped up. "Sumiiiin! What sort of disgraceful-?!" your priestess questioned, grabbing around for a sword as though preparing to threaten the girl with it. The other girl giggled and ran off, completely naked, into the hallway. She really was a carefree spirit...

... Crap. You really hoped nobody had seen her going out. A naked priestess running out of a god's room could be seen as cause for disqualification.

Keiko watched you with fierce eyes. You closed your eyes and pretended to be asleep. A painstaking hour or so later, you heard her leave, slamming the door behind her. Well... at least she was angry at Sumin, not you. All in all, not a bad way to spend the night.
