Delinquent, Fox and C-Rank Dungeon!

The sounds of a woman gulping, trying to swallow consecutively while smacking her lips, filled the room before a loud knock boomed. The sudden noise shocked the woman, causing her beautiful pink lips to open as she coughed and almost spilt the thick white milk filling her mouth.

"It's time for breakfast, Lord Ryuji."

"*cough* O-One moment, we will be down..."

"Are you alright? You sound to be struggling, Lady Yumiko."

"F-Fine, just some thick morning yoghurt... *cough*"

Ryuji looked up at Yumiko, her lips sticky and nose dribbling. He couldn't help but laugh. 

"You got too into it. Why do you always get so filthy?"

"Because... it feels good when I can feel you throbbing in my throat, and my mind goes blank."

"If you keep being like that, I won't be able to stop, and your stomach will bulge soon enough."
