How would the UT and UF skelebros do foreplay? Or would someone just jump straight to the punchline? Also favourite sex-positions? Sorry for all the questions... I'm nsfw-ask-starved! XD
Undertale Sans: He loves foreplay. A lot. Teasing you before fucking you is his life’s blood, so there’s no way he’s gonna pass that opportunity up. As for how he teases, he usually just goes super slow with making out with you and sometimes lightly slips a hand down, letting his fingers trail lightly against your parts. He takes his sweet time at your expense, and won’t start fucking you till you’re screaming at him.
Undertale Papyrus: He’s not very into foreplay, as he’s way too energetic to take his time and tease. The most he can do is make out for a little while before giving in and fucking you. Sometimes he does go a bit slower than usual if he is feeling like teasing, but like I said, he’s just too energetic to tease.
Underfell Sans: Oh boy. Now he’s the guys that just goes right in, rips off pants, and starts fucking as fast as he can go. He’s a little sex machine, so he’s usually thinking about all sorts of lewd things of you while he’s at work, and once he gets home and sees you… well, he’s just way too riled up as it is to do any foreplay beforehand.
Underfell Papyrus: mmmmm. Mm mm, boy, he goes all out. He ties you up, stripteases, lightly jacks himself off just a little, licking you, anything. Anything to get you to want him like nothing else. He’s secretly really insecure about being in a relationship, so teasing you till you beg is a really big confidence booster for him.
