Studying The Skeleton [Undertale SchoolAU]

“Okay students, take your seats. I am Prof. Sans.” He wrote his name down on the chalkboard so the students would remember. “I hope we will have a.. SANSational time with each other in this class.” He flashed his usual wide grin, adjusting the glasses taped to his skull. One of the teens giggled, liking his pun. He looked over. “Heh, well would ya look at that, didn’t even start teaching yet and I’m already loved~” He unpacked his bag, taking out the Biology Book. “Alright, who can tell me where you left off last time?” A boy on the first row stuck up his hand. “We left off on page 67, Chapter 3, Sir.” Sans nodded and went to the mentioned page. “Skeletons. Hah, how ironic, I have to teach you guys about myself.” Again, a few people laughed. Sans looked around, satisfied with the laughs, but his grin shrunk when he found they didn’t have a model skeleton. “Um.. You guys dont have a model skeleton in here..?” A girl from the back of the class responded. “No, some other kids broke it, but, you’re a skeleton, you could use yourself as a model. Right?” Sans stared at the girl. She had halflong, straight, brown hair and her eyes were brown with what looked like a tint of devilish red. She had a flowerpot with a single flower on her desk. It was a pretty flower with golden-yellow petals, but she had drawn an evil face on it with black marker, making it look unsettling. Sans snapped out of his trance, looking at the girl once more. “Myself, huh. That could work, I guess.” The students watched him as he started to undress, showing his perfectly white bones. To them it was normal, but to Sans himself, he was standing there naked. A slight blush spread across his cheekbones. “A-Alright. Who can name the bones for me?” The girl in the back raised her hand. Sans was strongly against the act of her touching his bones, but put the thought aside. “Y-Yes, Um-..” He looked on the classlist to find her name. “-.. Chara. Come here.” Chara stood up and walked up to him then started to name the bones on his body;

“I’ll start from the top. Cranium, Skull; Mandible, Jaw; Canines, Teeth; Clavicle, Shoulderbone.”

With every bone she named, she gave that bone a soft stroke or scratch, making Sans shiver.

“Vertebrae, Spine.”

She scraped her nails softly up the back of his spine.

“Sternum.”

Her fingertips moved to the thick bone in the middle of his ribcage, then wandering down his ribs.

“And ofcourse, Ribs. Humerus, Upper Arm bone; Radius and Ulna, Lower Arm bones; Carpals, Metacarpals and Phalanges, Finger Bones.”

Sans’ sockets slightly widen as she sat on her knees, pointing at his pelvic area.

“Pelvis, Hipbones.”

She stroked his pelvic bone, earning a soft gasp from Sans. She looked up, his eye flickering blue. With a small smirk she continued.

“Sacrum.”

She inserted her hand into his pelvic area and rubbed the named bone. Sans’ eye now flared a deep Cyan, his bones rattling in pleasure. He brought a hand up to his mouth to cover it as small gasps escaped him.

“Coccyx.”

As she touched the named bone, Sans’ eyes rolled back, covering his mouth tighter as he moaned. The class seemed a bit confused to what was going on, but most of them didn’t mind, as they were dirty sinners.

“C-Chara, T-That’s enough– A-Ahh..!”

“Femur, Upper Leg bone; Patella, Knee; Tibia and Fibula, Lower Leg bones; Tarsals and Metatarsals, Footbones.”

She rose to her feet and looked her teacher dead in the sockets as she spoke.

“Boy, Tibia honest, I never thought it would be so Humerus to touch bones. It was a skele-ton of fun~” After she said this, she returned to her seat. Sans blushed darkly as he heard voices from the back of the class.

“MMM WHATCHA SAAAAY!”

He shrunk down onto the ground.

“Jeeze, how embarrassing…”
