Chapter Text
“A-ahh, S-Sans…”
The yellow monster was panting, both claws gripping the edges of the desk she was propped backwards on. Her soft thighs cradled each side of the skeleton monster’s skull as he drove her wild with his fingers and tongue, one of his hands tugging her thick tail downwards to allow him better access. A summoned tongue swept across her clit with wide strokes, lapping up the wetness of her arousal. He chuckled, the sounds reverberating through his skull and vibrating against her tender flesh. She panted, letting her head drop back as he found a rhythm with his fingers and mouth.
Alphys had been queen of the Underground for four years now. The souls of the humans had been lost for good, but she and Sans had worked together to make sure nobody gave up hope. At first, her control over the morale of her subjects had been shaky at best, but now… Now, with the help of her friend, things were looking up. Steps were being taken every day to set up plans for their freedom, as well as plans for long-term survival here underground. Many monsters seemed to prefer staying here, anyway, fearful of the humans above.
She couldn’t blame them; even just one human child had killed so many overnight. They had taken away so much hope for them all—they’d taken away Papyrus, and Asgore, and… and…
Sans curved his finger just so and Alphys convulsed, hips tilting. “Gghhh, ha… hahh…” She panted, her breaths becoming shaky and noisy. Even when she was lost to pleasure, Alphys never raised her voice to a yell—instead, she was breathy and soft.
“Mm, c’mon, Alph, let go,” Sans murmured coaxingly, scraping his teeth over the soft flesh of her thigh. He dove back into her, continuing his rhythm but speeding up when Alphys went rigid and silent. She always did this right before—
“Aaahhh… o-ohhhh…”
There it was. Sans continued lapping at her, savoring the flood that hit his tongue when she came. She was sweet, salty, and so, so soft. She shuddered above him before sighing, her whole body relaxing. Sans got up on his feet and scooped her up, chuckling down at her flushed face.
“Better?” he asked, a smug grin stretching across his face. Alphys batted at him and giggled tiredly.
“Oh, stop it,” she admonished, and felt the familiar crackle of his magic as he brought them into her room.
“It’s late, you should get sleep,” he told her.
She opened her mouth to protest but he’d already laid her down and slid in next to her, wrapping an arm around her fleshy middle. His teeth met her rounded snout in a skeleton’s kiss and she sighed.
“All right, I guess I am kind of tired,” she relented, scooting closer to him and draping a claw on his hip. His fingers rubbed at her flesh absently, used to the feel of her scaly but smooth skin.
Their… relationship, if one could call it that, had arisen from need. Sans needed to forget his brother and everything to do with resets. Alphys needed to forget Mettaton, Asgore, and… Undyne. Now that everyone was gone and Undyne had died to the hands of that rabid murderer, Alphys could admit to herself that she’d been in love with the warrior. She’d loved her since the day Undyne had inadvertently saved her from jumping to her own death in a garbage dump. Undyne was powerful, passionate, and, to Alphys, beautiful. And when she had fought her hardest against the human, she had turned into an avenging angel, ready to defend the whole Underground with every ounce of her determination. But, in the end, even Undyne hadn’t been strong enough.
Alphys would never forget watching her melting body as she struggled to stay alive, her name on Undyne’s lips even in her last moments.
Sans had been so attentive and kind. He was patient with her, helping as much as he could with ruling the kingdom and keeping up appearances. Alphys had always known that the skeleton hid a lot behind his smile, but she never thought he was so incredibly gentle and hard-working. The laziness everyone had associated with him was a façade—though, to her puzzlement, he preferred that everyone saw him that way. He would always dismiss his own accomplishments and assure everyone he didn’t need praise or appreciation. And yet he would encourage Alphys every step of the way, always supportive and thoughtful.
Still, though, she didn’t love him. Not romantically, at least.
Alphys wasn’t stupid, however; she saw the way he’d look at her sometimes. The way his touches lingered. The way he would speak to her and light up like a Christmas tree when she came into the room. Once upon a time, the old Alphys would dismiss these obvious signs and sputter with embarrassment if anyone implied anything about them. Now, though... his feelings for her were as clear as a glass window.
For now, she just enjoyed his companionship. She looked at his peaceful expression as he slept and brought a claw to his cheekbone, gently stroking his face. Alphys cared about him so much. He was a good man.
It was just a shame that he’d fallen in love with someone who would never feel the same about him.
