“A-ah..R-red~!”

He stops midstep, his skull bright red. Was she…?“O-ooooh Red!” Oh yes. She is. He grins widely, she’s touching herself in the shower, and moaning his name. He’s gonna confront her, later though~…

 ~LATER~ 

 Red is chilling on the couch, watching some stupid show as he waits. She comes into the room, in a very short pair of shorts and a large sweatshirt. He grins to her, patting the spot next to him. “Cmere doll, gotta talk ta ya”She raises a brow but sits with him, legs crossed and facing him. He leans close, licking his teeth. “I heard ya in tha shower yknow. I can give ya tha real thing if ya want~” 

“Wh-what?! I-i dont…” she blushes and mumbles, pulling her legs into her sweater. He chuckles deeply and slides a hand up her thigh, sliding up her shirt and rubbing her stomach lovingly. “Aww don’t be like that. I heard ya mewlin fer me.”

 She sighs, stretching her legs out of her shirt and spreading them wide. “F-fine…p-please?” She looks up at him, blushing more. In a few seconds, her shorts and panties are off and his face is nuzzled into her thighs, licking and sucking at her pussy. She mewls loudly and arches into him, nibbling her lip and squeezing his skull between her thighs. He groans into her, licking and sucking her clit and folds, making her thighs tremble around his head.

 “R-RED I-IM CUMMIIING~!!” She screams, her cunt squeezing his tongue tightly, soaking it with her sweet nectar. He slurps up all of her juices, making her shiver and squirm slightly. He leans back, making her mewl breathy as he licks his chops. She swats at him and reaches for her shorts, but he grabs her hands and pushes her back to lay across the couch.

 “Aww cmon Dolly…” he coos, suddenly teleports them both into his room, which is dark and…slightly ominous? “Didja really think that was it? Well ya got a lot comin baby~” he grins wickedly, biting her neck.
