Flipping the script(swapfell)part 1

chapter 10

Sans trailed his phalanges up Papyrus's femurs, delighting in the trembling the action caused, seeing Papyrus's blush glow deepen. He adored that look on Papyrus; it was an imitation of innocence, but was certainly not a pale imitation. It reminded him of when they first began their relationship, of seeing Papyrus come undone just with a few touches...

He brushed his phalanges over the bones in Papyrus's pelvis, flicking his eyelights up to see Papyrus clench his jaw tight and clench his hands tighter into the back of the couch. It was amazing, seeing what just a few touches could do.

...and speaking of which...

Papyrus's magic began to coalesce, and that was where the magic—so to speak—took place. Sans enjoyed this part, watching Papyrus's magic form. The past couple of years of their physical relationship, Papyrus had been the dominant force, but now.....now, it was fascinating seeing Papyrus's magic battle itself on instinct versus familiarity. Seeing that golden orange magic swirl and partially solidify for several moments before settling on a sensitive mound that positively dripped with arousal.

How was it Papyrus managed to stay so perfectly untainted in magic after everything he'd been through, Sans wondered to himself as he lightly brushed his phalanges over the magic construct, hearing Papyrus let out a repressed whimper. Even considering Papyrus to be a masochist, light, gentle touches drove him further over the edge than strikes or cuts did, and Sans decided that was the greatest torture of all, letting Papyrus squirm and whimper until he finally got up the nerve to start begging for more.

The anticipation of that in the near future sent a shudder up Sans's spine as he lifted Papyrus's femurs to get better access, and dragged the tip of his conjured tongue shallowly between the folds of congealed magic.

The reaction was instantaneous, Papyrus's frame jerking hard as he buried his face against his humerus, cheekbones blazing orange as he struggled to keep his cries to himself. Oh, well Sans couldn't have THAT now. Sans moved his tongue in a slow, fluid wave, not letting more than the tip of it past the folds as he kept his eyelights on Papyrus's face, seeing sweat bead at his younger brother's skull and feeling the bones rattle from the effort it took to keep still and quiet.

He really had to give Papyrus a hand on his spectacular self-control, but Sans was not gauging Papyrus's control, not today. Today, he wanted Papyrus to scream, cry, and BEG.

Sans leaned back and licked his teeth, grinning at the pathetic mewl Papyrus let out at the loss of contact.  "You just stay right here, Papyrus, just like this," he commanded, setting Papyrus's feet on the edge of the couch cushions to keep his legs propped up before standing and hurrying upstairs to his bedroom.  He felt more than a little proud and glad that he had taken some notes from the book, especially in the area of tools he could utilize for this.

He pulled open a drawer and took out a few things he had crafted himself in the few spare moments he had the past two weeks, inwardly amused at the thought of his proficiency in mechanics and electronics being used to create something for THIS.  He absently thought about churning out a few more and anonymously selling them out; the sex toy industry was practically nonexistent in the Underground, and he was sure he'd make a killing.  Simple as they were, he was sure he and Papyrus could have TONS of fun with a pair of makeshift leather handcuffs, some cloth straps, a crop, and a remote-controlled vibrating pellet for HOURS.  He just had to be creative.

Sans headed back downstairs, pleased as could be when he saw Papyrus in the same position he left him in, albeit more flushed and unsatisfied.  Papyrus caught sight of him, giving Sans a silent look of desperation with a lustful heated undertone that Sans just couldn't stand to ignore.  Sans sauntered up to Papyrus, smiling down at him.  "Such a good boy, being so obedient," he purred, holding the pellet by the cord and swinging it to and fro in front of Papyrus's face.  "Do you know what this is?"  Papyrus shook his head.  "It's something that'll make you feel REALLY good."  He leaned between Papyrus's spread femurs, purposely getting close as he carefully wound the bullet between the ribs on Papyrus's sternum, using the cord to loosely tie it in place so it wouldn't snag or tangle, but still press against the sternum.  "And just for extra security..."  He reached up and used the cuffs to securely bind Papyrus's wrists together, making a mental note to put a discrete latch on the back of the couch he could pull out when doing this in the future.  After making sure Papyrus's hands stayed behind his head, Sans used the straps to tie Papyrus's femurs to his tibiae and fibulae.
