warning: cursing in my end note. also sans' reaction is actually just my irl reaction.
 

   Frisk: ...Is this legal?

    Chara: I... I'm doing WHAT to Frisk??? We're not even OLD enough to- *another picture* This is why I don't like humanity.

    Alphys: *completely straight face, not even blushing* Well... there's that.

    *"You're not freaking out?"

    Alphys: Seen worse.

    *"How?"

    Alphys: I've seen enough hentai for it to be worse. Not that I wanted to... no matter what, if you like anime, you can't escape seeing hentai at least once in your life...

    *"I'm so sorry."

    Undyne: What the fuck? Is that me? Oh my god that's disgusting. How can people draw us like that!? Eugh! *clicks to next picture* *it's of alphys in lingerie* ...Hold on. I'll keep this one.

    Mettaton: It's flattering, really. I love all of my fans, including the filthy sinners <3 If they want to draw me like this, who am I to stop them? Hmm... *scrolling through pictures* wow... some people are... creative, aren't they?

    Papyrus: *blushing like crazy* I'm in no place to judge, but... I feel like I should let people know?? That is not how we skeletons work... at all. The anatomy here is completely incorrect- *sees the start of hentai tentacles* WELL LOOK AT THE TIME IT'S TIME FOR ME GO NOW *dives out the nearest window*

    Papyrus 2.0: (according to Toby Fox, Paps litterally knows nothing about sex. So. Here's another version.) What is that thing on my pelvis and why are other people touching it? Does that hurt? Looks like it's painful!

    Sans: ...............Pfft... grk... HAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHAHA

    Flowey: You people have some interesting takes on what exactly I do with my vines to others.

    Toriel: O-Oh... my goodness?!?? What is this!!?! How outrageous! I would never wear such a trampy outfit like that! *scrolls down just a little more to see full image* *HORRIFIED GOAT SHREIK*

    Asgore: Wh...Why... am I wearing that...? I *clears throat* do not require a... leash?????????

  The internet is fucked up. Y'all are fucked up. If I had to see those horrific images when I didn't want to, then the least I can do is make this and leave it to your guys' imagination lol.
