"Sure, the toilet is there, I'l forgive for your trasgession for now." Mittelt looks relieve and is about to go but for some reason she still stands there looking agitated.

"Well?" Issei said, though she flush as what she is about to say.

"B-but you're still here, and I am a-about too-" Mittelt said,

"Is there anything wrong with me watching? you are my possession and this is my property," He said, can't find something to retort, she hesitantly squat in the middle of the toilet butt naked safe for her bow, her leg spread as she is about to do her business in front of her owner/master.

A few seconds letter a sound of dripping came, as she finally let it out. Issei look curiously as he look in fascination.

"So that's how girls do it." Issei said,

"This is embarrassing...."

After finishing, she clean herself as both Issei and Mittelt head outside.

"Yosh, I finally got a cute blond loli," he thought, thankfully she is legal, after that whole scene he decided to let Mittelt go on with her day, now having a second mole from the Fallen Group. He would be having the main head of the group and would be able to pick the lower ranks.

"Hehe, I even saw her picture, she has the most biggest one too." And so, he goes for the last female of the Fallen Angels.
