Story inspired by comic above

Sans took one look at the other him and said "There is no way you are me."

The purple magic Sans, dressed in revealing clothing, chuckled. A smirk lit his face. "Oh, I'm you all right." Sans' cheeks went blue as the other him stepped closer. "I'm the you that you deny...The one that lives out all those dirty fantasies."

Sans' SOUL thumped.

"Oh yeah...I know each and every one."

He turned away, feeling him wrap a hand around his waist. "Like the one where you ram Frisk against a wall and she screams your name."

"I- I don't know what you're talking about." Sans gulped.

Then a hand was cupping his chin and another was drifting under his shirt.

"I also know all the spots that make you uncomfortable."

"H- Hey!"

"And all the spots you want her to touch that drive you crazy."

The base of his spine was stroked, just like how he imagined Frisk would-

"And if I am you- which I am- then I know one thing for sure."

Sans gasped, panting for air. "Oh stars!"

The other him turned his face towards him. A purple tongue stroked his cheek. A purple eye was alit, like his blue eye.

"You like to play with Frisk."
