A selection of edited sprites from Undertale depicting Mettaton in the Waterfall garbage zone. In the first panel, he stands confidently at the center of the room, perched on one leg and with his lips pursed. He says: "Here, you say? Oh~ I didn't think you were the RISK-TAKING type~⭐️" It also seems someone is watching from behind the garbage... In the second panel, he's slid down to his knees now, his legs pointing away from each other. His arms are outstretched, and his hands form peace signs. His tongue is also out, and his eye is now facing the viewer. He says: "Alright, darling~⭐️ Time to show me what you've got!" The voyeur among the garbage now seems much more interested... He remains in the same pose in the third panel, but with strands of white cum covering his face and chest, and his pupil has turned into a heart. He says: "Mmnhf... Tasty~ Let's take it s little further next time?" The voyeur among the garbage now seems rather heated... The text box at the bottom of the screen reads: "* Sprite edit by RandomAccessMammaries!"
And here it is combined into one image!

A drawing of Mettaton, an android in black, white, and hot pink. He has dark hair over one eye, the visible one being the same hot pink as his lips and chest plate, and he leans back against a wall seductively, smiling at the viewer. His torso consists of a hollow section in which a pink heart can be seen floating through the glass front panel. He has a segmented metal penis, clearly the same metal as his arms and midsection, with a hot pink head; it’s erect, and he’s cupping it comfortably in one hand. A thin string of liquid the same pink trails down to his first finger.
If ever there was a character design just *made* for pinups…. #undertail #mettatonnsfw
