"Mammon, you're on cleaning duty today."
"What?!" Mammon exclaimed. Y/N just stood there, like the rest of the brothers, all trying to hold in a laugh.
"H-Hey! Don't laugh at me!"

Y/N sat in her room studying, being that it was a Saturday. It was particularly quiet, maybe because Mammon was busy cleaning so he didn't have much to yell about. Although, her mind wasn't on the history book in front of her. Her brain was mostly on the growing heat in between her legs. She'd never been brave enough to ever even think about touching herself, but tonight she just couldn't help but let the thoughts flow through her mind. Luckily, the answer was right behind the door. Mammon knocked loudly at the door and entered, despite Y/N being genuinely too hot and bothered to deal with him.
"Y/N, I need your help. Just this one time, I promise I won't ask again." Mammon panted, slightly out of breath from running to her bedroom.
"What is it Mammon? I'm a bit busy right now." Y/N sneered, irritation clear in her voice.
"I need help with cleaning." He stated.
There were a few moments of silence before an idea appeared in Y/N's mind. She smirked and thought, 'Mammon is easy to coax, this should be simple.' Y/N stood up and pushed in the desk chair before walking over to Mammon, arms crossed.
"I'll help you, but there has to be some sort of payment." She still had a cocky smirk on her face.
"C-come on Y/N, you know I don't have any cash on me. I can get you something though! Anything you want, just name it." At this point Y/N had sat down on her bed, her legs spread apart by a few inches.
"I want you to get on your knees."
Mammon blushed brighter than a ripe strawberry. "W-What?!"
"You heard me. On your knees. Now." Mammon slowly lowered to his knees.
Y/N hadn't worn leggings under her uniform skirt today, so Mammon had easy access. She spread her legs a bit wider so that Mammon had a clear view of her white lace panties that complemented her S/C skin. Mammon's large hands now sat on Y/N's inner thighs as his face got closer to her damp heat. She moaned quietly as she felt his breath on her slit. He pushed her panties over slightly to see her folds glisten with arousal. He stuck his tongue in slowly, instantly hitting her clitoris, making her breath hitch. He started to flick and roll his tongue around her clit as she groaned and ran her hands through his hair before pulling it a bit. He sucked it lightly which made Y/N let out a high pitched pleasured squeal. He continued to do this, sucking a bit harder now, loving the noises that his human was making. He moved away from her clit and licked across her entrance. She thrusted her hips forward onto his face, urging him to fuck her with his tongue. He did this, and it took her a very short time to cum. Mammon stood up, blushing brighter that Y/N had ever seen before.
"T-there. Happy?" He asked.
Y/N stood up as well. "Very," She stepped over and kissed him, not minding that she tasted herself on his lips. This is when she noticed he had an extreme hard-on.
"Maybe, if you really help me, I'll give you a special reward." She chuckled and he perked up.
