Sans sat at Grillbys for the fifth time that week. He loved the place since (Y/N) showed it to him and introduced him to everyone. Grillby was kind enough to allow him to put some of his meals on her tab. He would toss puns up and about getting everyone to groan, but they didn't really care. He reminded them of (Y/N).
He sat at his stool, right next to (Y/N)s' empty one. She was at a Toriels for the day, so he came to have dinner and chill with the fire elemental who was busying himself with cleaning a mug. "So how is (Y/N)?" He suddenly asked, his words crackle like fire, his voice was smooth. "she's fine.. why? worried she is around so many human males?" Sans joked, he knew Grillby wasn't worried, though they both knew what Edge had his friends do.. or more or less what he LET them do. "Course not. It is just..." He turns his head to look at the calendar on the wall near the dart board, their was a date circled in red, Sans noticed and raised a brow "she has that exact same date marked on her calendar, what's it for?" Grillby turned back to him and sighed "I do not think I should tell you.. but I am concerned about it." He placed the mug down carefully before leaning against the counter so he could whisper to Sans.
"How much do you know about monsters?" He asked lowly as Sans hummed in thought. "i've read a few books (Y/N) gave me, but what are you asking, exactly?" He leans forward to keep the conversation between them. "Did any of the books go into Heats?" Grillby raised a brow at the human who looked utterly confused at the question. "i... i don't think so... why?" Sans put his elbows on the counter, resting his chin in his palm.
Grillby looked around behind the human before leaning in again "Monster heats, are much like animal heats. It is a time where we wish to claim a mate, of course most times with out a mate we just want to... well.. have sex nonstop for hours, depending on the monsters strength in magic determines how long the heat lasts." He was so nonchalant about it, slightly embarrassed but getting it out all the same. Sans blushed lightly at the take, he was getting a monster version of the sex talk, by one of his crushes closest friends no less. "so the date on the calendar, that is when her heat starts?" Sans looked over to it, it was the 13th... just a day away...
Grillby nodded "Yes, normally she comes to me to help her with it, but she hasn't mentioned it to me, which is odd. Maybe she forgot, or maybe she was planning to go it alone... or maybe she was going to ask you, or one of the others to help her. I am not sure." He pondered aloud. The idea of her asking one of the other guys angered him, they would jump at the chance, he knew they would. But the idea of you asking HIM, oh boy that was a happy thought... should he bring this up to you? Or wait and see who you ask? Grillby snapped his fingers and forced Sans out of his thoughts "uh.. yeah? what about it?" He finally asked.
"Can you ask her about it? I don't want her to go it alone, that could be dangerous for her, and for the others. Tell her to let me know what she is going to do, I am still open to help her if needed." Grillby pulled away and went back to washing the mug.
Sans hated that he got mad about Grillby offering himself to her like that, last thing he needed was for another male to be apart of the competition he and the others were having for you. "yeah.. actually she should be home in a few hours, i'll head home and ask." He stood from the stool and headed out.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You had entered the house exhausted, babysitting Frisk was a task, the kid could get so hyper and you, like an idiot, gave them a few cookies. Instantly got them hyper and you had to hold them down with your magic as they flailed about wanting to run around. Using magic like that for some long is draining on you... not to mention your heat started soon, you're magic was already drained. You shuffled in to find Sans watching tv, but his eyes were offset. Like he was deep in thought, you carefully closed the door so not to startle him from his thoughts. But the click echoed in the silence and startled him anyway.
He turned to you with wide eyes before calming down. "oh, just you." His voice was off too, more gravelly, it was not helping you building libido "Oh yeah, that works as a greeting." You chuckled walking over to him and and sitting next him. His gaze never left your form as you moved, once seated you gave him a little smile "Something bugging you? You seem off." Sans only shrugged "not really bugged... more like... curious. yeah, curious is the word." He mused turning his gaze back to the tv "Curious about what?" You raised a brow smugly, whenever Sans got curious it was bound to be interesting.
He rubbed the back of his neck shyly and stuttered "i uh.. Grillby wanted me to ask ya something." This caused your head to tilt, your turn to be curious. "What might that be?" He blushed and sputtered out shyly "Hey w-wanted... um.. i-its a-about your uh.. your heat." He looked at his lap as your sockets grew wide "Did he seriously bring this up with you!?" Your voice was stern but not angry, he only nodded, his blush growing darker.
You covered your face in your hands and groaned "I am so sorry Sans..." That damn fire man... when you see him you are so gonna "it's ok... i was curious anyway." He interrupts your threatening thoughts, looking up at him with a raised brow at him. He rubbed through his hair "just.. he wanted to know what you were planning to do... s'all." His eyes never met yours. He found his feet more interesting then you at this moment.
"I... actually forgot about it for a while... only noticed a few days ago... forgot to ask him to help me." You put your hands in your lap and looked at the floor. Normal Grillby helped you with your heat, and vise versa, but you were so busy learning how to write and read wingdings, plus the reset you forgot all about yours to the last minute.
"he offered to help you again... told me to tell ya." He mumbled lowly, you almost didn't catch it. "Go figure he would... I don't actually want to... he misses so much work... he says he doesn't mind. But he can be such a workaholic I know he is lying. I most likely was gonna go it alone this time." You shrugged, his head snapped up and looked at you with a light sparkle to them.
"would ya... i don't know... be open to... me?" His voice went up a pitch near the end but the question sent you into a frenzy. "What!?" You looked at him, a deep flush on your cheekbones "i mean... we could just... science!? yeah! we can say it was for science reasons!? let me explore your body and you explore mine..." His blush grew as he lifted his hood up and covered his face and groaned into his hands. You couldn't help but laugh, he was so out of character, and adorable right now.
He only whined louder as you laughed "I'm sorry! Haha It's just... you are so cute..." You tried to calm yourself "Sure why not..." You covered your mouth and looked at him. He pulled his hood back to look at you.
Sure you were curious about the human body... and let's face it Sans is so cute for a human... plus that dick pic had you drooling... actually all of them did, besides the point. You were down to bone him if he wanted. Just say it was for science and no one got hurt.
He had his eyes on you silently pleading for you to confirm that one more time. With a sigh you leaned forward and whispered "Want to help me with my heat, Sans?"
