"Don't worry senpai I'll look after you." mash calmly talked to herself as she washed her master's face, as he laid trembling asleep in his bed.
"I'm so sorry. He was always immune to me, I didn't think a cold would hurt him," Hassan of Serenity sobbed from the doorway of Ritsuka's room.
"Well, now we know that master loses most of his poison resistance when sick. If you want to apologize please keep Minamoto and Kiyohime away from him alright. Senpai made it clear he was scared to have them around when he is sick." Mash replied gently trying to keep a calm smile.
"Right! But I wonder why he's scared to have them around when he's sick? Well, at least he doesn't feel that way about me." Serenity pondered as she left the room, the door closing behind her.
Mash sighed as she readjusted her senpai's blanket.
"No," he mumbled something that mash couldn't fully make out " bad snake!"
Mash took his hand "don't worry, there are no snakes or samurai mothers here. It's just Mash." she said calmly to him. He trembled for a moment before calming down, "And Nightengale doesn't know you are sick so you don't need to worry about her either." she grabbed his hand to try and comfort him.

The demi servant watched her master vigilantly. She reached her hand forward to feel his forehead only for him to grab her arm. To her surprise pulled it to his cheek, she didn't try to pull her hand away lest she accidentally wake him. He moved her hand again, this time by his cheek, she could hear him mumble something. He moved her dainty hand to his mouth and began to nibble on it.
"Senpai, what are you doing?" mash asked even though she knew he wouldn't answer, at least it didn't hurt, in fact, she found it kind of cute. She watched him continue to nibble on her hand only stopping to mumble something, the act seemed to help him rest. Mash tried her hardest not to blush at what was happening, the faint gnawing feeling was surprisingly nice on her skin, The demi servant lost herself momentarily in the pleasure. *Gulp* Mash's eye's shot open to find that her hand was now completely enveloped in Ritsuka's mouth.
The demi servant stared in shock.
"What should I do? I don't want to wake him, but I should try to get him to stop. He might choke, then again." her words trailed off for a moment "it does kind of feel nice". She watched him for a short while as he continued trying to swallow her arm, he looked so at peace yet he clearly wanted more of the demi servant.

Mash made up her mind, she carefully moved her free hand to Ritsuka's waiting mouth, easily sliding it in alongside its counterpart. Her angle carefully chosen to assist her master in what he was unknowingly trying. The tight feeling of his throat pressing against her slender arms was enough of a reason to go along with the idea, the fact it was Ritsuka only adding to the reasons. The master slowly began to swallow, pulling Mash's elbows into his waiting jaws. The eggplant knight assisted in the process by pushing her arms in slowly so as not to hurt her senpai. Mash didn't hesitate to feed herself to her master the risk to herself never even crossing her mind even as her shoulders entered his maw. She positioned her head so it to could enter with as little issue as possible all with a smile on her face. Ritsuka must have noticed the meal in his mouth as his tongue licked across mash's face.
"Do you like my taste senpai?" her question was answered with another lick across her cheek exciting a giggle out the kohai. She began to raise herself slowly so she could slide down her senpai's throat easier, she could feel Ritsuka lean his head back pulling her soft chest into his mouth. Her face lit up red at the new sensation, as any rational she had till now was washed away in the pleasure of the sensation of the tight confines of the mouth enveloping her added to by the occasional feeling of her senpai occasionally lightly chewing her in the process.
"Yes! Eat me senpai, hurry swallow me. Please. I want this." Mash begged to the unconscious man. He responded by gulping powerfully slurping mash down to her thighs in an instant, with the largest and meatiest parts of his meal down, the slumbering Rituka swallowed the last of his trust eggplant kohai.

"Good job senpai, to eat something of my size is a true achievement, I wonder if that's some spell you did without realizing, maybe a skill?" Mash joked as her mind returned to her. "I hope I don't give you indigestion". Mash froze for a moment as on the last word, digestion, it was something she didn't consider.
"I can use lord Camelot, no that won't work it might blow senpai up instead, wall of salt and wall of chalk could keep me safe." Mash closed her hand as she tried to think she could feel more mana flowing to her than ever before.
"Since I'm not in combat and have so much mana I should be able to use both for longer. If I'm careful they should be usable before they wear off". Mash quickly activated her skills so she could relax and enjoy the stomach around her.

Ritsuka yawned as he woke feeling better than he had in the last few days, though as he tried to move he found a massive bulging gut.
"What the hell? Did Raikō try to feed me her cooking while I was out?" He muttered to himself giving the gut a few rough pokes.
"Wah! What's going on? Is senpai still asleep?" Mash's cute but groggy voice asked from inside. Ritsuka tried to grasp what was going on, he knew two things for sure, one he had to find someone to get her out. Two he had questions to ask about how, why and possibly most importantly if they could try this when he was awake next time.
