Sans, Blueberry and Blaster have a very affectionate s/o. If they've been gone for a while and then arrive at home they will practically get a shout of "you're home!!" Before their s/o comes happily skipping to them so they can gently tackle them in hugs, nuzzles, and a lot (and I mean a lot) of kisses.
The pure intent of love, affection, cherished radiates off of them, and they're eagerly pouring it into their skelly datemate as they kiss their cheeks, lips and jaw.
This one was such a cute ask. I had so much fun writing it :)
Sans: Sans would love a person like this. He isn't the most loving guy when they're out in public but when they're home alone, he loves it. He wants every hour, ever minute, damn every second to be them laying together but he can't do that, sadly. When he came home and heard his datemate shout "You're home!" then they're on him, hugging him and nuzzling their cheek against his, he laughs softly. "Dang Y/n, I just got here" He was even too tired to try to come up with a pun right now, so he leans against them letting them give him all the love and cuddles and whatever else they wanted to give him that they wanted. It made him feel... really good. Plus, you know, he was sleepy so he would most likely fall asleep in their arms.
Blueberry: When he got home and his datemate skips over to him, throwing their arms around him in a tight hug, saying "You're finally home!" then they nuzzle his cheeks, peppering soft kisses against it? He blushed brightly but laughs his normal muehehehe laughter! "Ah yes! I am, good morning Y/n" he nuzzles them, humming happy to cover the softest of purrs coming from him. He really liked a datemate like this. The feeling of being wanted was very nice... the only thing he didn't like was cuddling too much but he could handle it for a little! He knew that he was gone for quite a bit of time. He loved the kisses -w-
Blaster: When Blaster walked in and saw his datemate who perks up, and grins "You're home!" they run over, jumping up which causes him to catch them in his arms and they start to pepper kisses all over his face causing him to laugh, shutting his eyes purring happily, his tail wagging quickly. He walks in, shutting the door with his tail. "Did you have to jump at me like that?" he nuzzles his snout against their cheek, "I could have dropped you" "Yeah, but you didn't" They respond. He loved it. He loved how sweet and caring his datemate was, how they loved him even though he looked like... this. He carries them over to the couch to sit down and he'd let them cuddle, kiss, and nuzzle him all they wanted.
Red: "what the fuck are you pattin' me for? I ain't a damn dog, Y/n" he huffs, turning his head away to grumble then pauses "well I didn't say to stop, did I?" He looks at you out of the corner of his eyes, a little flustered.
Lord: he pauses at the pats, his head turned down "Y/n... Why are you patting my head like that?" He is embarrassed and so confused? Why in good mother earth would he like being patted on the head like that?
Overlord: he would catch your hand, and shake his head "please do not" he has NO time for this strangeness, Y/n.
Demur: the second you do it, he's a bright blue color "I..." He shuts his eye sockets tightly, just leaning into the patting. He likes the praise but it's still embarrassing! "Thank... Oh... Thank you" he's hiding the lower half of his face into his scarf.
Commander: He pauses at the pats, then laughs "oh! Are you praising me for doing good, Y/n? Then please, continue!" He leans into tour hand, shutting his sockets, humming happily. He likes praise.
Blueberry: "oh! Ah... Thank you?" He laughs, tilting his head to the side, very confused. The praise is nice! A tad strange but he's seen weirder.
Blaster: his tail would start wagging against his will, and he shuts his eye sockets. "Y/n... I knew I should put it pat ya, but this is a little embarrassing" tease him about the tail wagging and you'd get a really embarrassed Gaster Blaster skeleton on your hands.
