Exit through Lumine's mouth

I'm not really too excited to shit myself out of Lumine's body so I decide to try to exit through her mouth. Even though I'm fully in control of her, I do have this sensation of the "water Mona" that's inside of me. Slowly but surely, I guide that water higher and higher. It's not long before I feel my legs start to wobble as I lose balance, signifying that I'm letting control go of her body. "A little more," I grunt in Lumine's voice as my vision shifts.

Next thing I know is I hear the traveler gag before vomiting me up as I land on the grass in front of her and promptly switch back to my human form. I felt fine as I looked down and was greeted with the sight of my own body. Although, Lumine didn't look great. She was on her hands and knees coughing as her floating companion rushed to her aid.

"Maybe we could've found an easier way if you were more helpful Paimon," I tease the floating pet as I lean down next to Lumine and place a hand on her back, "how do you feel Lumine?"

"I'm NOT useless!" insisted Paimon, stamping her foot in the air as the traveler slowly sat up.

"I'm okay, just surprised that's all," Lumine managed as she took a few deep breathes. She was a little shaken but otherwise fine.

"I was surprised too, it just kinda happened."

Lumine stood up and brushed herself off, "I don't know what that was, but being able to control people brings you higher on the tierlist. It's pretty awesome."

"What tierlist?" I asked confused, "anyway I'm glad you're taking it well. It can definitely be useful but I'm not really sure what to do with it as far as testing goes. Using something I'm not familiar with myself in battle may be risky."

"Oh!" Paimon exclaimed, "Traveler has a weird look on her face, maybe she has an idea?"

I looked back at Lumine and she had a smile on her face that could be described as mischievous... maybe even perverted? "I have a few ideas," Traveler said as she wrapped her arm around me, "come on Mona I'll give you some chances to test it out."
