Your feet drag against the waxed linoleum floors of Dr. Alphys' Lab and you can hear each individual step echo through the room. You were extremely low on HP and getting beaten senseless by that little spider brat so you decided to walk all the way back through the steam launchers to the lab to try and find something to refill your health. After calling for her several times without answer, you concluded that Alphys wasn't home and you groggily open the fridge yourself to see if there was anything in there you could take without her noticing. Nothing in there but about a hundred packs of instant noodles and an open box of some strange looking colorful Japanese candy. "What a weeb..." You think. Disappointed but not really all that surprised you turn around and inspect the rest of the kitchen. Suddenly out of the corner of your eye you spot it. A box pack of Kissy Kissy Soda, some bizarre product tie in from that human cartoon Alphys loved so much. The box was already opened so after peering inside to ensure it wasn't the last one, you grab a can and crack open the lid. You feel a sudden exhilaration as your HP meter fills and all the cuts and bruises from your previous fights are healed. Relieved, you turn to walk out the door when you hear a loud and obnoxious vibrating sound coming from the one of the rooms upstairs.
Cautiously, you go up the escalator to investigate. The buzzing gets louder and more intense the closer you get to the top. You briefly wonder if this was a warning alarm for one of Dr. Alphy's inventions that was about to self destruct, as it had certainly happened enough times in the past for you to suspect so. The source of the humming seemed to be one of the doors near end of the hall. After checking each room you curiously press your ear to the door at the end of the hallway by the second escalator. You freeze as you realize that a soft moaning sound can now be heard on top of the buzzing. Moaning that sounded like
"~Ooooh yes...
mmmmh! ooooh yesssss" the last words melting into a silky sigh
Suspiciously, you push the door open and tip toe into the room. The first thing you noticed upon entering the room was that it was pitch dark. Suddenly you heard a robotic voice gasp and the buzzing quickly stopped. That voice sounded... uncomfortably familiar, you realize. You press your hand to the wall trying to find the light switch. Overhead, the florescent lights of Alphy's lab flicker on and when they do you hear the same voice yet again shouting
"nonononoNONONO! Wha-what are you doing here? Get OUT!"
Before you had time to register what the voice had said you glance over to the back of the room and are horrified to see Mettaton, in his ex form, sitting with his legs spread on the floor and holding a pink bullet shaped sex toy in one hand and a strange looking book in the other.
