You were really getting worried now.

Ever since your little…'romp' with both of the skeleton brothers, Papyrus had not been himself. Well, at least you assume he hadn't been himself. Might have been easier to tell if you had seen him at all in the last three days. Hermit-mode didn't suit him, and with each passing day your concern for him grew. Sans seemed too embarrassed by what had happened to work up the courage to break down Papyrus' door to his bedroom, but you could tell your level of worry was nothing compared to his own.

"We didn't…force him, right?" He sobbed against your chest as you rubbed comforting little circles across his shoulder blades. "I wanted him so badly, maybe I –we, were too forceful?"

"Maybe we were." You admitted. The plan had been predatory from the start, really. But as you recalled the night's events, the image of Papyrus' blissful face was burned pretty much permanently into your memory. You'd never forget the way he had bent Sans over and just fucking…taken him right in front of you. A pull at your nether regions cemented what you already knew – you wanted that shit to happen again.

Who knew he had had it in him?

Sans shifted a little against you, peering up at you from his little nest, obviously wanting a response. Words of comfort. Words of guilt. Anything.

You smiled kindly. "I seem to recall him being pretty willing to bone you."

Sans hiccupped, a slight cerulean tinge appearing on his cheekbones. Adorable, but his uncertainty was still there. Until one of you talked to Paps, nothing was going to be known for sure, and neither of you would be able to get a wink of sleep. You hadn't even slept together since that night, and with Papyrus AFK, you weren't getting fed quite as well as you had become accustomed to. Papyrus was the only one out of the three of you that could actually cook something half-decent! You missed his booming, nasal voice, the way he somehow managed to sound fond when he argued with Sans, his hilarious little quips he offered while you all watched TV together.

Basically, there was zero pleasure left in your life.

And something had to give.

"I'll do it." You said, finally. "I'll talk to that silly skeleman and find out what the sitch is." You stood up, full of resolve, and Sans gave you a doting look that quite simply said; 'I think the sun shines out of your ass right now'. You gave him a curt nod, and took the stairs to the second floor two at a time. You were eager to make things go back to normal, even if that meant giving up your recently-acquired sex life. Although you sincerely hoped it wouldn't come to that.

"Paps?" You said meekly, a soft knock on his bedroom door serving as accompaniment. "Could I please come in? Sans and I are really worried about you…and to be honest, we miss your fabulous cooking."

You waited for what felt like an eternity, and you rest your head on the door with a resigned 'thunk', closing your eyes and listening for any sounds inside. You thought you heard a slight shuffle, and it was confirmed when the door opened the tiniest of cracks. You glanced up, forehead not moving from the door, and you could only just make out the outline of the familiar skeletal face from the darkness of his room. Meaningfully, you drew your hand up, letting it rest against the door frame – a gentle request for entry. Papyrus seemed to eye it suspiciously, before seeming to come to some kind of conclusion when you made no further attempt to force your way inside.

"Do you…" He cast his gaze to the side, sheepishly. "…Really miss my cooking?"

You chuckled good-naturedly, bending at the waist to slide dramatically down the door. "Oh, Papyrus! I am famished, I have not been able to bring myself to eat anything but your delicious cooking!"

He opened the door a little wider at that, his chest visibly swelling with pride at your words.

"True, The Great Papyrus' possesses skills that are unparalleled! I apologise for being…not dissimilar to the wily turtle this week, and causing you such gastrointestinal discomfort."

You stood up straight at that, tilting your head to the side in confusion.
"Paps…actually, I think it is me that needs to apologise to you. Could I…come in and talk for a bit?"

The tall skeleton flinched a little, making to close the door, but you raised your hands in front of you in a surrendering gesture. "JUST to talk. I promise, sweetie."

He considered your words, your face, your tone. You had never seen him this…suspicious. You didn't blame him – last time you were in his room, you had kind of been going to town on yourself on his bed.

"Alright, human."

You slipped inside quickly before he changed his mind, but you didn't fail to notice the way his breath hitched when you just barely brushed against him. Guess he was still a little on edge considering everything that had happened. He leaned forward towards you, his form seeming so much larger than you remembered, and you found yourself unable to move as he reached around to shut the door quietly behind you, plunging the room into darkness. You blinked rapidly, willing your eyes to adjust to the light and for your heart to stop racing. You had come here to talk…this was about Papyrus, not you. But it was hard to remember that when his hand was still resting on the doorknob, and you could FEEL how close he was to you. Why wasn't he moving away? Just moments before, he didn't even want you in his room…

"Human." He uttered, voice level and too-serious.

"Paps…?" You gasped, your shoulders quaking a little at his tone.

"I realise you came here to converse, however…" His gloved hand ghosted up your arm, making your hairs stand on end and raising gooseflesh in its wake. "Could we…not talk…for a little while?"
His face was hovering near your ear, his breath hot and his voice so full of need that you couldn't deny him.

"Whatever you need, Pap…I'll give it to you." You were proud of how even you were able to make your voice, when inside you were quivering with want.

And then he embraced you, his long arms encircling your comparatively smaller body and drawing it flush against him. He felt solid, safe…right. You loved how tiny he made you feel; how had you never noticed how tall he was before? How deceptively strong and welcoming his arms were? A small sound escaped your lips as he pushed his teeth against your neck, dragging them across your flesh and nibbling gently at the sensitive area. It was making your head spin almost instantly, and you huffed out loudly while tilting your neck backwards on instinct. He seemed pleased at that, and he nuzzled you affectionately, burying his skull into your hair and inhaling deeply with delight. His hands were wandering all over your body, skating purposefully all the way up your back and sides while pressing you even closer into him. The indents of his fingers were almost scratching your back through your clothing, and the pressure felt amazing as he massaged every area with great care. He seemed to love your spine, and he worked a hand under your shirt to drag a finger up and down it almost teasingly. A low grumble emanated from inside his ribs as he used the very tip of his finger to trace across each crevice and rise, and the sound made you feel a bit giddy as your face was pressed right against his chest. The rumble passed through your body, and the amount of base in the sound surprised you in the most delicious of ways. You could feel the vibration in your core as he made the same sound again. You guessed it might be a skeleton thing, but it was still doing things to you that sent a shiver up and down your spine with unexpected intensity. Shit, were you getting wet just from this?

"This is…how I wanted it to be." Papyrus sighed, happily.

And it dawned on you.

"Paps…" You started, biting back a moan as his tongue made an appearance against your earlobe. "Was…that your first time, before?"

You felt him nod against your neck, his demeanour a little shy now as he tried to find the words. "Last week, I…was in heat."

You gripped at his arm in surprise. You had read about this. For monsters, heat was a bi-annual thing that rendered them very…ahem, 'needy' and almost aggressively wanting to reproduce. It had been comparative to a female humans monthly cycle, but was so much more intense that typically monsters were granted leave from work with pay as they were not generally in their right mind.

"Oh my god. That…explains a lot. Paps, I am so sor-"

"I don't remember most of what happened, but I remember it felt really, really grand. And I…remember not being able to get close enough. Wanting to be closer. To really feel you, as I am now." He picked you off of your feet and snuggled you as close as he could, and your heart melted as you threw your arms around his shoulders to help support yourself. You couldn't believe it. How much exactly did Paps not remember? There were a couple of er…things, you really hoped he didn't forget. One of those being Sans. But you quickly decided that now was not the time as you had at some point wrapped your legs around him and were grinding against his pubis with abandon. Papyrus cried out needily, his legs shaking so much that he was forced to sit down heavily on the edge of his racecar bed. That was just fine by you, as you now had some purchase to straddle his femurs and ride him even harder. His phallus was beginning to form in his shorts, and you could feel the beautifully curved shape of it with perfect clarity through your underwear. Your folds enveloped it on either side, and you let out a surprised moan as the head of it pushed against your clit and sent a spike of pleasure through you. You leaned back a little, using one of your hands to flip your hair back off of your face and look Papyrus in the eyes. His sockets were lidded, but followed your accidentally alluring motion with rapt attention. You saw nothing but complete and utter worship in his skeletal features.

"Stunning…perfect…n-nyeh, human you are-"
"A-ah, Paps!"

He had taken his gloves off, and reached out to cradle the sides of your face. It was a touching gesture, and he urged you forwards, connecting your lips and his teeth in something that resembled a kiss. His thumbs stroked little circles on the pulse points underneath your ears, making your face flush with pleasure. How could this damn skeleton make tender touches feel so good? Usually you didn't feel like this unless someone was touching your sex.

The sudden bucking of your hips made him part his jaw in surprise, and you took the opportunity to create suction and bring his tongue into your mouth. You greedily swallowed his long, drawn-out moan, but he didn't stop making those sweet little noises as you sucked on his glowing ectotongue. Those noises almost made you feel drunk, and with each new one you drew from him you could feel the desperation between the two of you reaching a new peak. Dry-humping was something you hadn't done since you were a teenager, but you didn't remember it feeling nearly this good before. Papyrus seemed to agree, and he reluctantly broke the kiss, unable to keep up with you. He almost collapsed on the bed, leaning backwards onto the pillows and grasping at your hips to urge you on faster, looking up at you in awe. Moan after moan fell from him, punctuated with choked gasps and sobs when you undulated your hips just-so. He had to squeeze his eyes shut for a moment when you were vocal right back, powerless to handle the erotic sight of you as you grinned open-mouthed and panting down at him. He looked so wrecked, face aflame with orange and unable to even help you by thrusting upwards. He never let go of your hips, but he was just letting you bring you both to your crest, letting you have your wicked way with him, and his submission to you turned you on with a sudden passion.

You distracted him momentarily with one hand gripping at his ribs and pumping hard a few times, and his eye sockets flew open almost comically wide as his jaws parted in a silent scream. You felt his feet leave the bed and his toes curl in ecstasy when he felt what you had really been up to…you had used your other hand to nudge both of your undergarments aside. Your wetness enveloped him on all sides, and with a particularly wanton thrust, the very tip of his dick entered you and you gasped, reaching down to rub furiously at your clit as you came first, the feeling of being suddenly stretched so perfectly just being too much. The pressure built up inside you and crashed forth, the waves of pleasure rolling through your body over and over as Papyrus used the last remaining strength in his arms to move you against him a few more times.

"-H-HUMAN!" He wailed, his head snapping forward sporadically. His chin connected with his own chest as he strained upwards, eyes scrunched closed tight as he came just outside of you, the thick ropes of cum splattering your belly and adding to the sensation of your own release. He called your name so sweetly, and you moaned your own reply as you collapsed forwards on top of him, utterly spent. You hadn't realised just how hard you had been panting until now, and you were gasping for air desperately and still shaking from the intensity of your orgasm. Papyrus wasn't much better, and his breaths were punctuated by the odd 'nyeh' as his dick twitched between your bodies. You smiled against his bones, planting a few quick kisses along his collarbone while he stroked lazy circles along your back.

His grin couldn't have been wider, until a small whine from the doorway made you both freeze.
