Edgy Love (fell Sans x reader)

Shopping then lemon

You walk into the living room from washing the dishes to ask sans some kinda uncomfortable questions.
"Hey sans?"
"Yeah pet?"
"Um, can you um buy some stuff for me?"
"Depends... like what?"
"Um..."
"Pet you're gonna have to tell me."
"It's um..."
"Pet spit it out come on." Sans said getting slightly irritated.
"Well um, I need some... feminine products..." Sans stiffened at that.
"Um... do you really need those..?"
"Sans are you seriously asking me that 😑."
"Hey I don't wanna buy those!?!"
"Well I can't go outside apparently!?!"
"Ugh, fine WE'LL go get some because I'm not doing that and you're not going out alone."
"Ok thank you sans, but ya know I'm also gonna need some underwear." Sans smacked his hands against his skull and dragged them down his face.
"Fine, but only cause it's necessary."
"That's what I figured, I'm probably also gonna need a new bra."
"Seriously pet..?"
"Yeah my boobs get all sensitive and it hasn't really been a cake walk goin around here with no bra."
"Well it's been for me.~ but fine... we'll get you a bra." He said not sounding happy.
"Hey we wouldn't have to buy them if you didn't ruin the ones I had in the first place."
"Hey I didn't stop to think at the time about your 'sensitive boobs' and your fucking period being such a problem."
"Hey you don't gotta be an asshole about it! It's not like I want this to happen!"
"Jeez fine whatever let's just go to the shop real quick." You went by the door and got your shoes. Sans then got up from the couch, went in the kitchen, rooted around the drawers, and then came back out with a leash in hand.
"Seriously sans."
"Yeah, we can't have you goin around town without it."
"Ugh fiiine, but I'm NOT happy about it." Sans then clipped the leash onto your collar.
"Heh suuurrre pet."
"S-shut up you ass."
"Heh nah I know you love it.~" sans said opening the door and you two stepped out and started walking toward the shop.
"At certain times, but not now!"
"Heh you won't be saying that in a few minutes pet.~"
You stiffen, you'd think you'd be used to that by now but you just weren't.
"Sans are you ever NOT horny?!"
"Yeah you just happened to fall down here when I was in heat."
"Of fucking course."
"Heh don't worry pet it'll be over in about another month."
"Sooo how long does your heat usually last?"
"Eh about three months."
"Holy crap, horny for three months?!"
"Heh yeah gotta say there's not really a downside to it."
"Yeah for you maybe!"
"Hey you enjoy it pet." You blushed cause he wasn't wrong.
"Well whatever let's just get my stuff." You two made it to the shop and the owner shot you a dirty look and sans shot one right back, she then went back to what she was doing.
"Alright hurry up and pick out what you need."
"Ok fine, you probably don't wanna come with."
"Ugh of course I don't but I have to." You then found the aisle with the personal products and you tried to go down while sans was hesitant to but did anyway. You luckily found the same  stuff you used on the surface and sans was happy you found it so fast he practically booked it out of the aisle dragging you with him. "Ok we got the stuff now go pick out a set of underwear."
"Ok jeez why are you so rushed."
"You know why pet."
"*sigh* yes."
"Don't look so down sweetheart we'll have a great time I assure you.~ you know we will."
"Heh ok well Ima get the other stuff." You then found some bras and underwear and you picked out a set and went back to sans. "Ok I guess I'm ready to check out."
"Good cause I'm ready to check you out.~"
"Oh my gah sans," you said starting to laugh. "That was just awful."
"Hey I'm being honest." You two then walked to the check out.
"Heh you gotta get some stuff for your bitch sans." The clerk said.
"Hey!! Rude!" You exclaimed getting moderately pissed off.
"Hey bun, don't be talking about (y/n) that way!" Sans said standing up for you. Oh my gah sans actually stood up for me... AND he said my ACTUAL NAME! This is gonna be bad...
"Hey sans lighten up, you don't actually care for this thing do you."
"Hey ya know-" you tried to stand up for yourself but Sans beat you to the punch.
"She's not just a thing bun, and don't think I won't beat the hell outta you if you don't shut your damn mouth!"
"Jeez sans calm down!" The clerk said getting all defensive.
"Heheh Welp apologize to (y/n) then I'll calm down."
"Jeez, sorry (y/n)..." she said sounding both surprised and annoyed that sans was making her apologize to you.
"Um it's fine..."
"Alright so is this all you two are getting." She said still sounding fairly annoyed.
"Yeah that's it." Sans said sounding like his normal self.
"Alright now typically this would cost 20 g but seeing as you're real pissy today sans I'll go cheaper just cause I'm nice."
"Heh whatever how much is it."
"15 g"
"Ok here." Sans hands over the money and you gather the stuff and you two leave.
"Sans I'm honestly surprised you stood up for me like that."
"Well you don't deserve to be treated like shit, even boss realized that."
"Yeah I remember when boss first met me he didn't even like the idea of me, now he's so much nicer to me compared to before."
"Yeah Trust me if boss were in there with us and he saw the way she was talking about you, he probably would've killed her on the spot for treating you like that."
"Huh, I'm flattered." You honestly didn't know how to feel about that but that seemed like the best response.
"Yeah the boss really cares for you as if you were his baby sister."
"Awe well that's sweet."
"Heh I guess so."
"So what do you think of me?"
"Huh?"
"Do you love me sans?"
"Heh, yeah, of course I do, how could I not?" You felt all fuzzy hearing him say that. You kinda grew feelings for sans especially after the first time he had sex with you, and he's been getting a lot nicer and apparently more defensive over you. That just made you all happy and warm inside, also slightly turned on. Getting turned on at this point was pretty good cause you already knew you were about to get the bone zone once you got home.
"Sooo you love me." You joked with him poking at his ribs.
"Hey quit that," he said moving your hands from his ribs. "Save that for later.~" he said whispering in your ear. It sent chills down your spine. He then pulled you closer to him with the leash and he rested a hand on your ass making you blush. "Whaddya say we take a shortcut.~"
"Heh that impatient are we,~ the house is just over there." You literally pointed at the house.
"Yeah but we can get to the bed room faster.~"
"Sure then sansy~" he definitely took you up on that offer and he covered your eyes with his hands when he released you, you were two were in the bedroom.
Sans then spun you around to meet his gaze, he had a huge smirk on his face and a lustful look in his eye, you returned the smirk and you both leaned into a long passionate kiss. You then placed your hands on Sans's chest. Sans then stuck his tongue out of his mouth and began to lick your bottom lip asking for entrance which you allowed. He then shoved his thick, long tongue in your mouth, you two fighting for dominance. Sans clearly over powered you though. As he was searching every nook and cranny of your mouth he began to remove your clothes starting with the jacket you were wearing, he then pulled away from the kiss only for a second so he could remove your shirt. He then went right back to what he was doing but now he was gently massaging your bare breasts as well, making you moan in pleasure. He gave a dark chuckle in his nonexistent throat as he backed you against a wall. You kicked your shoes off and sans trailed his hands slowly down your back to your shorts. He was playing with the hymn of his your shorts with one hand and grabbing your ass with the other. You then trailed your your hands down Sans's shirt going underneath the hymn of his shirt and you began to play with his ribs. He shuddered to your touch and he groaned as you started stroking them giving each rib special treatment. You could feel Sans's member grow in his shorts as you kept messing with his ribs. Sans then grabbed you by the thighs and he lifted you up. You then wrapped you legs around his pelvis, feeling his member poking at your womanhood. Sans then moved from your mouth to the crook of your neck. You moved your head up giving him more room to lick and bite at your neck. He trailed your neck in little bites until he got to your sweet spot. He already knew where it was, but he has to give you special treatment. You were moaning out as he began to attack your good spot. He bit down hard drawing blood making you moan his name out loud and grip onto his ribs extremely tight making him groan in pleasure and bite down on you harder making you bleed even more. Sans then began to lick up the blood that trailed from your neck to your breast. He pulled away to get a good look at you. He left a big bruise on your neck matching others that he had made before, he snickered at the sight and he set you back on the ground. He then removed his jacket and you took off his shirt slinging it to another side of the room. He wrapped his arms around your waist pulling you closer to him again and you just placed your hands on his scratched up ribs and traced the scratches with your finger tips. "Ugh fuck (y/n)~" he moaned in pure satisfaction. He then began to take off your shorts. When he removed them he had to tease you. "Oh, no panties? You filthy sinner~"
"Heh your fault I didn't have any.~" he then tackled you onto the bed.
"Heh well sweetheart, it's just easy access for me~" he then goes away from your face sticking out his long tongue just teasing you with it. You looked up to see what he was doing. He was moving down to your womanhood, looking up at you, flicking his tongue in a teasing motion knowing you were watching. Once he made it down there he began to lick your entrance barely pressing his tongue in just to mess with you. You shudder to  his slimy tongue pressing onto your womanhood.
"S-sans quit teasing," you said wanting more of him. You heard sans give a dark chuckle and He then shoved his tongue inside of you all at once making you arch your back and yell his name. Sans then grew a smirk on his face seeing the state you were in. He began to flick his tongue inside of you as he pressed his thumb against your clit making you pant and moan. You began to thrust your hips trying to take in more of him, he just felt so good. He continued to move his tongue inside of you and he managed to get deeper. He began to curl his tongue inside of you making a knot form in your stomach.
"AaAhh S-Sans I-I'm about to c-cum.~" you panted out. He managed a chuckle and he began to flick his tongue inside of you at a more rapid pace until you came all over his tongue. "AAAHHH SANS~" you screamed out as you came onto him. He lapped up all of your liquids and he then positioned himself at your entrance.
"You ready for the best part pet.~" he said pushing the tip of his member at your entrance.
"H-heh y-yeah.~" you panted out nodding you head in anticipation.
"Heh good~" that being said he shoved all of him member into you at once making you reach out for his shoulder to grab.
"UUUGGGHHH!~" you winced in pain but pleasure. You started to arch your back trying to adjust to his size, panting and fighting back tears. You let out a few huffs when you finally adjusted.
"You good for me to start?~"
"Y-yeah, I'm ready.~" he started off by thrusting into you slowly, managing to push his full member deeper and deeper inside of you with each thrust making you moan his name. "Oh Sans~" you said taking your hand off of him and gripping the sheets. "G-Go faster, I need you more~" you panted out.
"Say my name,"
"Sans~" he began to go a little faster.
"Say it louder, come on."
"SAns~" you said slightly yelling.
"Come on sweetheart you're almost there.~" he said pumping into you faster.
"SANS!~" you moaned out as loud as you could and Sans began to slam into you at inhuman speeds. "AAAaahhh~ SANS!~" you screamed out his name in so much pleasure.
"Ugh, you're so t-tight (y/n)!" Sans said as his thrust became sloppy.
"S-sans, I-I'm gonna-" you cut yourself off as you came onto Sans's member. Sans didn't stop however, you started to feel numb to his thrusts, you were just to overwhelmed with pleasure and you came again. You were a moaning panting mess, you then felt the slight twitch of Sans's member inside of you and he pulled out coming all over your stomach and chest.
"*huff* *puff* that... was great." Sans said in between deep breaths as he plopped down next to you.
"Heh yeah, *huff* it was." You replied.
"Here *huff* lets clean you up. *puff*" Sans used his magic to Clean you up.
"Heh thanks."
"Heh no problem." Sans's then rolled over and wrapped an arm around your waist and pulled you close. "I love you, so much, I hope you know that (y/n)."
"Of course Sans, I love you too."
"(Y/n)..."
"Yes..?" You said concern laced in your voice.
"I know this is gonna sound weird, but... will you be my girlfriend?" Your heart skipped a beat knowing that he actually did love you.
"Of course Sans." You said smiling like an idiot.
"Heh that's great to here." He said while you snuggled your head under his chin. "Anyways get some rest sweetheart, we gotta big day tomorrow."
"Why what's going on tomorrow."
"Eh you'll see."
"Well ok I'm to tired to question, heh."
"Alright goodnight sweetheart," he then kissed your forehead.
"Goodnight sansy." You then slowly drifted off into sleep in Sans's arms.
