Serafine hurriedly scrambled out from under the Succubus, fumbling with her art supplies for a cloth to wipe herself clean with. She roughly scraped at her face with an old rag, removing the spunk from her face and neck. She yanked her robe over her head just as she heard footsteps on the stairs outside.
The Succubus watched her with a smirk as Serafine rushed to the door, locking it. She heard the handle jingle as someone on the other side tried to open it.
Serafine felt a cold chill rush through her euphoria as she answered, "Hang on, I'm getting changed. I, um... Spilled the paint all over," she lied before giving herself a once over. She unlocked the door and opened it a crack, sticking just her head through. She made sure the door was angled to hide the evidence in the room.
Outside the room was Rebecca, Patrick's daughter. She was a year younger than Serafine and the two girls couldn't be any more different. Rebecca's blonde hair and blue eyes, her brightly colored clothes and obsession with romance dramas and being trendy were a sharp contrast to Serafine's dark hair and eyes and love for anything geeky. Despite that, they were good friends and sisters, though they shared no blood.
"Making a mess of things up here? You know Dad'll get mad if you don't clean it up," Rebecca said, standing on the stairs in her favorite outfit- an oversized hoodie with her favorite boy band with skin-tight leggings on. Even with the hoodie, it was clear puberty had favored her over Serafine when it came to curves.
"Yeah... Made a pretty big mess. I'm going to clean it up, but I don't want anyone coming in; its all by the door and I don't wanna spread it," Serafine said before she stiffened up. Behind the door, she felt a hand lifting up her robe and a soft tongue run along her slit and shaft. She felt her face redden.
"Alright... Mom brought home pizza, it's on the table. Come down and have some before Dad eats it all." Rebecca said with a wave of her hand, already turning around.
Serafine nodded at her before closing the door and glaring at the Demon, who had her head fully in Serafine's robe. Serafine stood with her back against the door as she felt the Succubus run her tongue along her labia, kissing her nethers while the Demon's hand stroked her cock which grew from just above her pussy. Serafine's breath hitched as she felt the Demon's tongue enter her.
Serafine's hands reached down, holding the Demon by her hair and pulling her in as she moved her hips slowly. The cock in the Succubus' hand swelled to nearly its original size, curving a gentle arc back against Serafine's body. The nineteen-year old yanked her robe off, feeling the cock slap against her stomach and the bottom of her own breasts. The sticky clear-white fluid splashed against her sternum and the underside of her breasts as the Succubus stroked her with one hand, her other arm around Serafine's leg and grabbing her ass.
Serafine tried not to moan as she Demon masterfully licked and teased her pussy, biting her lip as the hefty shaft and head rhythmically slapped against herself. Serafine's legs gave out, but the Succubus' strong arm supported her as she continued pleasuring the human girl. After another minute, Serafine was covered in hot cum, her cock erupting a geyser of her sticky fluid all over her tits and face. The girl fell to the floor, cock resting between her soaked tits as the Demon kissed and licked the fluids off her skin, only serving to further stimulate her. Serafine's dick twitched as another spurt washed over her chest.
Serafine was exhausted, completely worn out. The Demon continued to kiss her breasts and cock, sucking at her small, perky nipples before kissing her on the lips. Before Serafine fell unconscious, she heard the sound of the door locking, and the Demon saying "Well... As payment for such a good meal, I guess I can clean up."
Serafine woke up in her bed, wrapped in the warm quilts her mom gave her years ago. She lay in bed with her eyes closed, thinking about the strange dream she had. It had felt so real, but things like that don't happen. She sighed, slowly sitting up, pushing herself up. Something soft and warm met her fingers and she opened her eyes at the unexpected surface.
There, naked as in her dreams, was the Succubus, asleep in Serafine's bed and hugging one of the plush dolls. Serafine's fingers were sunk into one of her breasts. The girl froze, looking at the sleeping woman as she realized it had not, in fact, been a dream. Serafine jumped back, immediately pulling at her pajama bottoms to examine herself.
Sure enough, there it was. It was smaller than last night, only about five inches long, but it was stiff. She stared at herself in a mixture of shock and horror, watching as it slowly went flaccid before her eyes.
