Discovering a cum fetish

"Judging by the look, you've never done this before?" Nihja asked, biting her lip as she felt her sisters warm breath touch her kitty.

Mitzi shook her head before diving in, using her succubus tongue to lick up all of the dripping seed from her thighs and back up to the source of it. Being ticklish, she was giggling as it happened before feeling that tongue rest on her kitty.

"Mmmmmm~"

Mitzi certainly knew how to use her tongue, expertly rolling it around those slick wet folds and planting kisses on the button above. Pressing her mouth against the soft snatch, her eyes closed as she indulged in a new act of sexuality. It was quite a beautiful sight, seeing your sister's face up against your pussy, licking and eating it for dinner. The kind of sight that would make a girl quiver in want, and don't even get me started on how it felt to her.

Nihja yelped and gasped with an opened mouth feeling something slick and wet enter her, oh god that felt sooo good! Not as hard as a dick or with as much girth, definitely squishy around her inner walls and super well lubricated.

'Oh god, oh god my sister's tongue is inside me!'

'She is tongue fucking me!'

"Oh fuck yea." She panted, now holding Mitzi's head in place and riding her tongue, squeezing it and squirming around as it pushed in and out collecting every trace of semen within. Even her fingers began to explore, rubbing her clit in circles and massaging around her kitty to enhance the feeling.

Has she done this before? Certainly feels like am expert at this.

Slurp!

Chup!

Gulp!

"F-fuck, clean me up Mitzi... every drop, ohh gosh I'm there!"

Gulp!

Slick!

Gulp!

Squealing through gritted teeth, she pressed her sister's head onto her and rode out the incoming wave of ecstasy. It felt surreal, like an out of body experience almost as she grinded through that talented tongue inside.

"Mmm... hmm! Mmhh!"

Closing her eyes, she hummed to herself in bliss and relief.

"Mm! Mmmm! HMM! MMMM!"

She gasped feeling Mitzi slapped her thighs and let go, her head springing up with a deep intake of breath.

"AAAAAIIIIIRRRRRR!" She yelled, finally giving relief to those poor lungs of hers as she gasped and recovered slowly. Nihja couldn't help but to laugh.

"Fucking ey, you trying to kill me!? Let me breathe next time!"

"I'm sorry hahaha, but the look on your faaace hahahahaha!" Nihja doubled over and nearly fell off the desk, much to her sisters annoyance. Though it was contagious as even she chuckled lightly at the absurdity of it all. Imagine being suffocated from eating pussy? How rich!

"You've got some cum on your chin by the way." Nihja added.

Mitzi flipped her off before licking that strand away and gulping it down with the rest.

"Gosh, wouldn't have taken you for a cumslut sis. Kinky."

"Not a word of this, okay? And fuck you, this was my first time doing that."

"Hehe, well today was a first for both of us."

They both shared a smile before remembering Roy's sleeping body nearby, naked with his clothes piled up and a mess of folders and papers on the floor.

"Huh... oh shit! Five minutes before opening, help me clean this up!"

"Clean what, him or the floor?"

"All of it!"

"Jeez, bossyyyyy!" Both girls shared another laugh before hurriedly dressing up as Mitzi reverted back to human form.

"Well, today was quite a day hehe."

"I'll say, you think he'll be fine like that?"

"Eh, he'll get in trouble maybe but beats waking up on the floor naked." Mitzi replied with a smirk. In several minutes both girls managed the impossible and cleaned up the place, even dressing up Roy and carrying him onto the chair. He was slumped over on the desk, snoring loudly.

"He'll thank us, trust me. Let's get out of here before we get caught."

The girls snuck out of the back before walking into sunlight among the crowd, oblivious as to what the two girls had just done. They couldn't help but giggle in excitement.

"So, I just discovered two things."

"What's that?"

"That Roy snores in his sleep." They giggled some more before Nihja grinned and winked. "And also that someone has a cum fetish!"
