Has her eat out sister Sabine

“Fire hair, sit on ground and open legs.”

The imp commands and you quickly sit down and spread your legs wide apart. You run your hand over the soft hair and velvet warmth of your cunt. The imp gestures between your creamy thighs.

"Raven hair, eat her pussy."

Olivia gets down on her hands and knees and crawls between your legs. Her hands stroke your thighs and you shudder as she smiles sweetly and lowers her mouth to your cunt. The pale heart shaped loveliness of her ass is raised as her tongue spreads your labia and tickles your engorged clit. It feels so good it makes you gasp and moan. You don't care if anyone other than Olivia and the imp hear it, the ecstasy of her tongue on your aching slit is something you want to share with the world.

The imp who infected both of you with its toxins lands behind Olivia.

“No good. Butt is much too high, raven hair. Bring it lower.”

Olivia, eager to accommodate, slides her knees farther apart from each other which brings her hips closer to the floor. The position looks a bit uncomfortable for her, but is just right for the randy imp.

“Good raven hair.” The imp chuckles and strokes Olivia's bottom. “Fire hair chose well. Will reward later.”

You have no doubt this ‘reward’ he speaks of involves his cock. You want to taste it and feel it stretching every hole. You know you will cum again and again for your imp master. It makes you smile just thinking about it.

Olivia moans into your slick quim. The imp is rubbing and teasing his dick all over Olivia’s pussy. You remember how not long ago you felt his cock poke against your then virgin pussy. Suddenly her moans are interrupted by a short grunt, and you learn Olivia has lost her chastity to the imp.

“Two virgins, one day.” The imp cries triumphantly, “And pretty ones too. Must be luckiest imp in the abyss.”

The imp takes a good grip of Olivia’s hips and starts thrusting his daemonic cock in and out of her quim. Olivia pushes her hips back at her **** as much as she can. Her large breasts are squished between her ribs and the cold stone floor. Her tongue follows the example of the imp's cock and pokes your pussy, trying to get to taste the sweet nectar of the imp's semen still in your cunt.

You place your right hand on your right breast and play with it. You squeeze your teat, pull at your nipple and rub in circles. You place your left hand onto sister Olivia’s head and pull her closer as you grind your pussy against her. You fuck her mouth until her lips are dripping with your flowing honey.

As you near orgasm, the pale skin above your patch of pubic hair starts to turn red. Is that because of the oncoming orgasm? No, it’s something else. Red lines start appearing onto your skin. It’s a large circle with a five pointed star inside and letters appear in each of the star's points. You can't read the letters, they belong to an unknown daemonic script, but you know what the symbol represents. It is a pentagram.

Once the symbol is fully formed, it pulses with daemonic energy and your skin loses its red coloring and turns back to its usual pale color.

“Fire hair got marked!” The imp shrieks. “Seed and egg got marked. Now you mine forever!”

“I got marked.” You repeat softly as you come to the realization you have been impregnated by the imp.

“I got marked!”

You tell Sister Olivia as you resign yourself to the fate of being this imp's personal fucktoy.

“I got marked!!!”

You cry out loud, happy as can be, as your orgasm hits and you cream all over sister Olivia.

“Yeah, you got marked!” The imp cries back. “And now I’ll be marking your friend!”

The imp pushes his cock into Olivia’s cunt as far as he can and unleashes a torrent of hot daemonic seed into her human pussy. Olivia lifts her mouth from your cunt and moans loudly.

“Oh yes. Fill my pussy. Fill it with your unholy sperm. Yeees.”

When he stops shooting sperm into Olivia’s pussy, the imp pulls out and starts flying again.

“Fire hair chose good. Raven hair is great fuck. Time for fire hair to get reward.”
