"Wa-Wait, Sans." Frisk stammered as she scampered backwards on all fours. "Can't we talk about this?"

Sans suddenly teleported to stand right over Frisk. "Don't worry, baby." He purred, smiling dangerously, but somehow still seductively, at her. "I'm an expert." He slipped Frisk's shorts and underwear off in one motion. She yelped in surprise.

"I'd try to console you by saying it won't hurt much, but I'd be lying." Sans hooked his thumb into his pants waist, and lowered it, revealing his glowing purple penis.

Frisk swallowed nervously. "Wa-Wait.." Sans slipped off his pants and smiled deviously at Frisk. "Open your legs, honey."

"N-No." She stared up at Sans, her blue eyes filled with fear.

"I know ways to make you, so either way, it'll end the same." Sans warned. "Do it voluntarily and it won't get as messy."

"No." Frisk restated, shaking a little. Sans sighed. "Welp, you asked for it." He leaned over Frisk's legs, his face inches away from hers. She stared up nervously at Sans.

Sans lowered his face to Frisk's, slowly kissing her. "Th-This isn't that bad.." Frisk thought to herself. Then Sans forced her mouth open, sliding his tongue in.

She gasped and tried to pull away, but he continued to kiss her. Sans's hands traveled between Frisk's legs, easing them open.

His cock entered her, pulling slowly in and out. She gasped in surprise and pain. "A-ahhh." Frisk cried as Sans began to thrust faster into her. Tears pricked at her eyes. "St-stop. It hurts." She whimpered between moans.

"We're just getting started, baby." Sans replied. He slipped off her sweater, leaving Frisk in only a bra. Sans began to lick between her breasts and traveled up to her collarbone. His fingers traveled over her body, caressing her gently in contrast to the rough thrusting motion.

Frisk moaned, tears falling down her face from the pain. Her moans increased as Sans started to lick her neck, finding her sweet spot and gently sucking on it. He thrusted deeper into her, releasing more tears from Frisk. Her cheeks flamed red.

This went on for a few more minutes, until finally Sans pulled out of Frisk. She lay on the floor, gasping and shuddering, semen dripping out of her.

Sans sat back and watched Frisk sit up and hug herself. Tears streaked down her face as she breathed raggedly.

Suddenly, a faint "ding" sounded, and Frisk's soul appeared in front of her, blue. Frisk looked down in devastation and turned to Sans. His hand was raised, and he had a dangerous smile. "Break time's over."

He moved his hand and Frisk flew across the room to settle on one of the columns lining the hallway. Sans teleported to stand in front of her.

"Pl-please." Frisk begged, pain and fear in her eyes. "No more." Sans only smiled. "We're going to try something different." He placed his hands between her legs and forced them apart. Frisk whimpered in protest.

Lowering his face to eye level with her opening, he stared intently. Frisk stared down at Sans, her blush growing at the intensity at which Sans was staring. Then, he moved forward.

Sans's tongue entered Frisk's opening, which made Frisk cry out in shock at the unpleasantness of the sensation. She moaned as her face coloured red. Frisk grabbed onto her thighs and cried, her tears dripping down her face.

Finally, Sans backed up, releasing Frisk. She slumped against the column, weak and shivering. "I think I've played with you enough. I guess I have to kill you now." Sans sighed, fake regret in his tone.
