*Lemons*

Frisk matched his mouth again to her lips with a passion while letting out a low moan. He returned the kiss with loving passion. Her hand gently went under his shirt and once under she pulled his rib to pull him down on her. A sharp gasp of pleasure left him... sweet stars the things she did to him... Her tongue inserted into his mouth cavity, searching every inch, tasting him. As she helped remove his shirt, exposing him to her, she continued to make out with him. He shivered, not with cold though even as he pressed against her; his tongue dancing around her own in the kiss. She was everything to him. Warm... soft... kind... passionate... loving... the list went on and on, and he didn't need to think to know that list because it was etched into his soul.

Frisk felt she was learning more and more about him as each day went by. How his smile made her jump for joy. The way he held her hand. The experiences that they alone experienced together, these are things that she needed to remember. She started to kiss his ribs and work her way up to his neck before kissing it. He let out a groan with each kiss, the warm bones beneath her lips tingling with the pleasure she brought. He ran his hands through her hair.. .so soft, he wanted more; more of her.... of everything that she was willing to give.

"Sans last night... ummm can we try it again..."

"which part?"

"Well the beginning was nice but the part where you kinda rocked my world is the part I was talking about." He seemed to contemplate this a moment, trying to pick out precisely the moment she was talking about. She leaned near his ear canal.

"The part where you ravaged me with your "hands" I believe." His eye lights brightened with the memory. "Then you pressed my body against the bed so hard that it made me squeal with pleasure... do you want me to go on...? Then you bit my neck before we collapsed in our ecstasy leaving me a moaning mess." She said lustfully into his ear. His entire being seemed to hum, he knew what she meant. It took a bit of magic to do, but he'd enjoyed it about as much as she had seemed to.

"i remember." His tone had dropped an octave as he pulled back a little to meet her gaze. How could he forget? It had been an experimental thing on his part, but she'd seemed to thoroughly enjoy it. He summoned the magic within him even as he leaned down to kiss her passionately. She moaned in pleasure as she let her hands rub up and down his spine. A groan left him as her fingers found sensitive spots along his spine, the newly summoned hands slid up her legs, and along her arms, he shifted back as another set roamed along her sides. His hands left free to work on getting her out of the dress, he slid his tongue along the skin he was slowly exposing to the air as if the taste of her was what sustained him.

Her head rolled back as she started to moan with every 'kiss' she received. Her body trembling in pleasure as her body quickly heat up with everything happening to her. "Sans...Sans..." She started to murmur under her breath like a chant as she gripped the blanket and the grass below her. He made short work of the clothing, the sound of his name on her lips egging him on.

"so beautiful..." He murmured before his tongue slid over one breast, his other hand skimmed over the other, his fingers seeking out the most sensitive spots even as his free hand roamed down her waist. The dizzying effect that he had on her was making her go crazy. Everywhere he touched made her moan in ways that no other being could do. Her hands just grasping and moving, up trying to catch his lips but to no avail.

"Sans let me kiss you please." He shifted to fulfill her request, kissing her heatedly just a few seconds before his hand left her waist to glide over her leg and to her warm core. His fingers teasingly playing over her skin. Frisk's mouth never moved away from Sans' as he started to tease her more and more. She wanted him to hear her moan his name, to feel her breath quicken, and every time he made her squeal. His fingers slipped along the warm flesh folds, the touch teasingly gentle. He wanted to hear more from her, he craved it like a desert man craved water. She made sure her mouth is on his teeth as she started to say his name. Kissing him at the same time.

"Sans... oh my god Sans..." Her hands found his spine, rubbing and clawing him every time he found her sweet spot. It took only a few tries before he'd isolated the spot, very gently teasing it; he wanted to drive her crazy with the pleasure of it, the sound of his name made shivers of pure delight snake through him even as he shivered from the feel of her against his bones. The hands still gliding along her arms, stroking her thighs while the other pair had shifted around to squeeze her bottom. She wanted to so badly keep up with the kisses but the moment he found her sweet spot her back naturally arched and her legs bent so he had better access to her. The way things were going, she would be spent too fast.

"Sansss I need y-... oh god ... Sans please..." Her eyes rolled in the back of her head as she bit her bottom lip in pleasure. He shuddered, the hands along her arms shifting to help him out of his shorts even as he crooned, teasing her just a little longer.

"whatever you want... i'm all yours." He shifted to replace the hand that was teasing her with the pulsating magic member. She bit her lip in anticipation. He quivered a little as the magic slid past the folds and slowly into the warm cavern beyond. As he entered into her, her body naturally responded in a moan and she started to feel herself gliding up against him. To touch him more. He pressed into her, shuddering with the feeling of her body welcoming him.

"Frisk.... sweet stars..." Her body shuddered with each thrust and the pleasure came to her faster.

"God Sans... you feel so good."

"nnn... you feel amazing... every time..." She put her hand in her mouth to try to prevent herself from screaming his name, but she was quickly succumbing to the inevitable, and he'd moved that hand.

"don't hide... i love hearing you."

"OH GOD SANS SANS...Oh, GOd....I am- SANs!" Her legs clamped around his waist while she screamed. Her words sent shudders through him and his thrusts had a bit more force than before; hearing her drove him crazy... and he loved every single second of it as he pushed them both towards the brink. Eventually, the pleasure was too much as her body clasped over his manhood and she gave into her ecstasy. He let out a final groan as his body shuddered through his release, spilling magic into her and it spread through her; as if to reassert his claim and feed the mark that he had given her. As he collapsed against her, his mind didn't even register that he hadn't told her how precisely a mark worked, only a few necessary things. Like how it was visible or how a monster could scent a mark. Since it was temporary, of course, there were limitations to it, like how long it would stay on its own without his magic to replenish it.

Her breath finally steadying down from all that has happened.

"Well, I think I fucked up Paps rules to dating..."

"nah... you just broke the rules... and you did say you were a rule breaker." He replied a bit teasingly, his tone has a purring rumble to it.

"I do love the sounds you make... god if we didn't just finish having fun.. I would take you here and now."

"hmmm... i'll keep that in mind although...." His next words have a bit of a teasing tone to them. "that's a bit of dangerous information to a monster going through heat..." Frisk didn't know if she should ask him if he was in heat or if that he was soon to be in heat. A part of her wanted to know so badly, but another part wanted it to be a surprise. So in the act of rebellion, she pressed her head next to his ear canal.

"I can't wait until than..." A shiver went through him.

"tease. don't tempt me."

"Don't tempt you to what?" Her body shivered in the air, but she still licked the side of his face. He chuckled at her words.

"unlike most monsters... skeletons can control when their heats occur."

"So what is this heat ... and will it be warmer than I am currently...?" She asked realizing how cold it is out there...

He couldn't help but laugh even as he wrapped them both in the blanket to help keep her warm.

"heat is a mating cycle every monster goes through. depending on the monster, it can be controlled, put off or even sometimes made to be more subdued than normal but it cannot be denied and happens at various points in a lifespan. some monsters get them once a year, some bi-yearly. others get them every two to five years. In the case of skeletons, due to our species being some of the highest in magic, it can come around, a minimum, every two years." Frisk became so entranced by what he was saying but a little part of her fantasized.

"I just wished I could of heard you tell me all this in your lab coat..." Her face blushed despite the cold.

"figured i'd save the details of my heat for that..." He replied with an almost devilish smirk. She looked at his eye lights

"So ... when will I get to meet this great scientist Sans... I heard so much about... " He pretended to give it a long consideration, but the slight widening of his smile gave a bit of it away.

"i was thinkin' a couple days from now. he's swamped ya know..." He winked with that last part. She giggled. She loved this game they were playing.

"Well will you tell the good scientist that I have seen his boney ass and I love it." she winked

"i'll be sure to pass the word on... so he doesn't make an ASSignment to give you more than you bargained for." Frisk busted out laughing. She tried to say the next line with a straight face.

"Well I was hoping when I get to see him that he would experiment on me on how many sounds a human body can make." Sans didn't have a response for that, just the thought made him shiver with delight.

"Although I might need him to do a xray of me as well because I am pretty sure I have a bone in me that doesn't belong." He laughed, even at the same time that he quivered. He knew humans had bones beneath their skin and the thought of actually seeing something like that made his soul thud a bit in his rib cage.

"I hope the scientist will be careful with me as he pokes and prods my tender flesh any way he wants. Just to get the desired results that he needs." She said lustfully. Sans nipped at her shoulder.

"you really know how to stir me up..."

"Thus I get bitten ... that showed me ... sorry I went too far Sans." She smiled.

"oh no... don't apologize... as for the nip... well... it's just to satisfy that itch that you started. instead of starting another round..." There was a lustful purr in his tone as he said as much.

"Oh.." Her mind was still pretty hazy from earlier. "Well if the good scientist needs to I am always willing to be his lab rat."

"nah... you're far too precious to be a mere lab rat."

"I know... I just ran out of scientist flirts..." She admitted sheepishly. His response to that was a soft chuckle. She stuck her tongue out at him.

"You try to come up with some... mr. romantic skeleton who seems to drive me up the wall crazy." She teased.

"you're copper tellurium." He replies with a smile.

"CU... TE... God Sans... using that sexy brain of yours against me...."

"you did say." A pleased rumble in his tone.

"If I were an enzyme, I'd be DNA helicase so I could unzip your genes." A surprised, pleased laugh came from him.

"I was going to save it for later, but here you pulled out the big guns and so ... plus I looked it up on the internet... so for now ... you win this flirt war...." She kissed him gently on the mouth. He returned the kiss gently.

"i enjoy our little 'battles.' " Frisk laughed.

"You know... if we keep meeting like this," she motioned pointing out the nudity between the two of them. "we will need our own place because Mettaton can't afford all the mattresses." He chuckled at that.

"actually i've been working on that with Al. the specially made material you can put over a normal mattress just for such... occasions. mostly for heats."

"Do you mean when you "rise" to the occasion?" She laughed at her own stupid joke. He chuckled a bit.

"mm.. well yes, but also because heats can be... very wild." This made Frisk a little nervous "How wild are we talking Sans... like, am I going to need to sign a waiver before going on this ride or in the wild like I will never be able to walk because my body won't let me."

"well... in my case... probably the lather. in the case of other monsters... the former."

"I will say the chance of dying doesn't seem as pleasurable as one would think... but seeing as how crazy our relationship has always been I will be ready for when it comes." She smiled at him. His smile this time is a reassuring one.

"i won't ever let it be that bad starlight. i treasure you far too much, and i'm keenly aware of the limitations you likely have. i'd be lying if i said i wasn't sometimes holding back. i don't ever want to hurt you in this if i can prevent it."

"Sans I trust you body and soul and I can feel that you were holding back that is why the last couple times I've been a little more... ummm... minx like as you call me."

"ah. that explains that."

"If you trust me to allow you that freedom than I trust you that in the end, you won't hurt me." He hummed a little.

"i think i need to just 'experiment' more first. i only know so much from books. Once i get a better idea of your limitations starlight... then i'll take you up on that."

"Well... I will say this if you need to have to you can always look at my body instead of an anatomy book." he chuckled a bit.

"what i'm thinkin' of a book wouldn't help with anyway."

"I love teasing you moonshine... thank god you are mine." She kissed his cheek. He flushed a little.

"heh.. i enjoy it myself. on both ends." It took a moment to recognize what he meant as a flush came across her face.

"Okay .... We need to get back, and you mister, need a cold shower." A rumbling laugh answered her, but he helped her get dressed before dressing himself, making sure she wasn't cold; he didn't really feel the cold the way she did, as he told her once. He picked up the lanterns that had been overturned and blew them out, adding them and the blanket to his phone's inventory.
