Jen laid naked on Liz's bed the demonic tome opened up in front of her. She has spent a few hours studying the book but her efforts were often interrupted buy Liz's family orgies. She has managed to learn a few things of note however, firstly demons don't actually eat human souls they feed on "Sin" a type of life energy created from sexual acts. Though it largely serves to maintain a demon's mental health Sin is also their primary source of magic. Demon magic was almost completely reliant on sex, common components were sexual fluids like cum, milk, and on occasion blood. Having an orgasm was usually what triggered spells, and the more powerful spells required multiple people, Jen couldn't wait to try this for herself.
Jen was having a problem thought She had become desperately horny and it was getting hard to think straight. At first she thought it was just the subject mater of the book but over time it she began to wonder if their was some demon magic interwoven into the tome. What ever the reason Jen was now horny as hell and unfortunately Liz was down stairs getting snacks. Desperate for relief she rolled onto her back and began to finger her now moist snatch. But just as she was about slip a finger inside she notices someone standing in the door. It's Dakota Liz's younger brother, He's a cute boy having long blond heir that covered one of his hazel eyes. his skin wasn't as dark as his sister's but it was still darker than Jen's. He's a very shy boy which made it fun to tees him as his reactions are always very cute. But Dakota also has a bit of an exhibitionist streak often going in public naked or wearing very baggy pants that made it obvious wen he had a boner, but usually making sure that no one saw him.
Thankful for the boy's curiosity and needing to satisfy her lust, Jen spreads open her legs giving Dakota a good view of her wet pussy. She focuses intently on his penis as she strokes her dripping cunt making every motion and sound as erotic as possible. It doesn't take long for his penis to start swelling and throbbing as he moves closer to the bed. Entranced by Jen's wet and warm vulva his breathing grows heavy as he began to rub his hard cock now dripping with pre cum. Feeling that he's waited long enough she parts the soft lips of her pussy showing Dakota her moist entrance giving him a clear invitation. Unable to restrain himself any longer he climbs onto the bed and begins to rub his cock against her wet vulva. After a few moments he begins to press against her vagina slipping into her and sending shivers up her spine.
Given the environment he's been raised in Dakota was naturally very skilled at having sex hitting all of the best spots. Jen screams and moans as he thrusts into her driving her closer and closer to the peck. After only a few minutes Jen spills over into an orgasm warping her arms and legs around the boy as he continued to slide in and out of her quivering pussy. As soon as she recovers from her orgasm another begins to build as he kisses and suckles her large tits. Jen experiences three orgasms and is approaching a forth wen she notices Dakota's movements growing more frantic. "I... I'm cumming mmm Jenny can I please cum inside?" he asks. "Ohhh yes yes FUCK YES mmm fill me up!" She moans in response. With that he begins to move rougher and rougher before thrusting as deep into her womanhood as he can sending both of them spilling over into ecstasy. Using her legs Jen pusses him deeper into her pussy as his penis deposits glob after glob of his white hot seed into her.
Jen spends a few minutes just cuddling with Dakota wen a hand brushes his hair. "Hehehe you having a good time there squirt?" Liz says before giving him a kiss and asking him to give them some privacy. "But sis I want to do demon stuff with your girlfriend too" he says pointing at the book. "Not right now, me and Jen still need to figure things out" she says "but we might need your help later okay". Disappointed but deciding not to press it further Dakota decides to give Jen one more kiss before leaving the room. "Girlfriend huh" Jen says in a teasing tone. Liz looks embarrassed a blush forming on her cheeks and she seems to become self conscious of her own nudity. Suddenly she feels a hand brush against her cheek making her turn just in time for Jen to plant a kiss on her lips. "I think I like the sound of that" Jen says "Liz you've stood with me through this whole thing even before you knew about the curse." "I feel so close to you and your family and I'm so glad that you want to become a demon with me, Liz I think I'm falling in love with you."
Liz looks in to Jen's deep blue eyes before retuning the kiss slipping her tongue between her lips as Jen pulls her lover on top of her. They make out for a few minutes before Liz brakes of "speaking of demons have you been able to learn any thing" she asks piking up the book. Jen sighed "it's been slow but I have learned a few things, for example demon magic is completely reliant on sex to work". "which means that the curse was probably not created by demons, if that was the case then it would probably require you to have sex with the person you want to curse." Liz looked at Jen with a mix of confusion and concern before asking "Jen are you saying you can reed this?" "What do you mean?" Jen asks confused. "Jen... this book isn't written in English" she says as she hands the book back to Jen. Jen studies the demonic tome and sure enough she's right it doesn't even look like English it was written in some demonic language, but she could read it, she understood it as if it was something she knew her entire life. Jen looks back up at Liz clearly shaken "Liz what's happening to me?"
Liz gives her a warm hug trying her best to comfort her as Jen stats to cry "this has to be the curse I can't think of anything else that could be doing this." "That's what's scaring me" Jen sobs "Liz I don't know who I am any more, am I still me or am I the curse?" "The worst part is that I like who I've become, yea I'm a slut now but before I was cursed lets face it I was a heartless bitch." "I've become a much warmer and more caring person, I could never do the stuff I used to do now, before I would never even consider forgiving Kyle let alone feeling grateful for him." "And I would never have the relationship I do with you and your family, Liz I'm scared what if the curse gets lifted and I go back to being a bitch again?" Jen plus away from her lover to look into her eyes tears dripping from her face "Liz what if I'm not real?". Liz pulls her in for another hug before saying "Jen how do you think I feel, look at my family their is nothing normal about having sex with your family." "Jen I probably wouldn't exist if it wasn't for the curse, I don't care if your not real by that logic I'm less real then you are." "I love you Jen I want to become a demon with you and maybe If we summon a demon they might be able to give use some answers."
Jen gives Liz a kiss before wiping the tears from her eyes and opening the book "Their was one demon I think might be able to help us" she says before turning the tome back to Liz. On the page Liz saw a picture of a strange feminine figure shrouded in shadows and darkness "who is she?" she asks. "It says that her name is Scathach, She's a primordial demon known as the Mother in Darkness and has given birth to some of the most powerful demons" Jen explains. "Supposedly she's very motherly, she has eons of knowledge, and I don't know why but something about her just feels right" she says. Liz thinks for a moment before asking "how do we summon her?" "Well it looks like Dakota will get to help after all as it requires three people to preform the ritual" Jen says "as for the components we'll need something to draw her sigil with, a large open space, and breast milk." "I have plenty of chalk, and theirs an abandoned warehouse not far from hear" Liz says "as for breast milk, my mom is pregnant right now and she sometimes let us have some her milk, how much do we need?" "Enough for the three of us to drink." Jen says.
Deciding to preform the ritual the next day the two girls spend the rest of the night making out and having sex before finally going to sleep. The next day is spent getting every thing ready Dakota was very happy to hear he'll be helping and became oddly exited wen he learned what they were doing. Liz's mom Alexa found the request a bit strange but decided that they were just having some fun so she filled three small bottles with her milk. The rest of the day was spent with Liz's family having sex, eating, and just spending time with them. Liz has four siblings soon to be five her older sister Lily, Dakota her little brother, and her two little sisters Blair and Harper. Alexa her mother is a beautiful woman with very long brown hair, dark eyes, and dark olive skin. Liz's Father Morgan was someone that Jen didn't meet until after the curse and it was obvious that "She" was the one who was cursed, Morgan was an athletic woman with a 10" long dick, long blond hair, and bright golden eyes. Jen has considered asking them about the curse but decided against it not wanting to bring up memories that could poetically be painful and they might not even be aware that they have been cursed.
They leave after super before it gets dark, the three of them chose to wear very little clothing as they wont be needing it for the ritual. When they arrive at the warehouse Jen immediately begins to draw the sigil a fairly intricate symbol that largely consisted of a number of spirals coalescing into a single point. It took over an hour for her to finish as she needs to make the sigil as accurate as possible otherwise it just wont work. She felt so grateful for the chalk as she could easily just erase the mistakes she inevitably made and was even more grateful that Dakota thought to bring a flashlight. The moment she finishes they complete the preparations by placing the bottles of milk on three circles that are on the outer circle of the sigil. With everything ready the ritual begins.
Jen, Liz, and Dakota remove their cloths and take their positions in front of the bottles. Jen holds the demonic tome in her hands taking only a few moments to find the correct page. Even though she was still uneasy about the fact that she could somehow understand this language she was grateful for it non the less as she begins to recite the spell. The demonic language was beautiful sounding breathy and erotic oozing with desire and lust, it feels so natural for her to speak it as she feels herself becoming aroused. As she speaks the sigil begins to glow with a pale white light that pulsates from the center and travels to the bottles of Alexa's milk. By the time Jen finishes the light had dissipated leaving the three glowing bottles. Placing the tome on the floor Jen reached for the milk and taking its place siting in the circle and opening the bottle before turning her attention to Liz and Dakota who are doing the same. In unison the three took the bottles to their lips and begin to drink feeling the warm fluid rush down their throats initiating the finale stage of the ritual.
Almost immediately they begin to feel heat flow throughout their bodies and their arousal skyrockets. Jen's and Liz's pussies become flooded with feminine juices that quickly begin dripping to the floor and Dakota's penis grows becoming hard, erect, and dripping with pre cum. They quickly start to masturbate, the girls fingering their wet cunts and the boy stroking his throbbing cock. As they pleaser themselves the sigil glows brighter then before and a black sphere begins to form in the center. The very darkness itself grows darker and shadows begin to move joining with the sphere and making it grow. They find their aerosol becoming unbearable as wen ever they think they reached their peak it keeps growing higher and higher. As the warehouse is filed with their moans the darkness continued to coalesce forming a dark mass. Suddenly they are struck with an intense wave of pleaser as they experience an orgasm unlike anything they had felt before. The dark mass begins to take shape as they writhe and moan on the floor, fluids squirt from the girl's pussies and Dakota is covered by thick ropes of cum produced by his throbbing cock. Jen in particular feels something flowing out from her and into the darkness quickly realizing that she is producing Sin.
The darkness takes on a large feminine shape though clearly not human as three white glowing eye pierce through the shadows. After only a few moments the darkness fades revealing the demon beneath. Scathach has long messy black hair, soft dark brownish skin with glowing white tattoos that accentuate her features. Her lower half is dominated by a massive tail covered with thick black fur that travels up along her spine joining with the heir on her head, the under side left bare revealing the soft skin beneath. The large puffy lips of her pussy dripped with fluids her anus tucked just below it. Four large breasts decorate her chest the lower pair being slightly smaller in size and were tipped with black nipples. She has four strong arms each with five long claws, her hands covered with thick black fur that stops at her elbows. Her face is beautiful with a cute small nose and soft dark lips with sharp fangs beneath, Her large eyes are pools of black with pale white irises and glowing slits for pupils. Two small black horns grow from her forehead and two large black antlers grow just above her long pointed ears. "The human realm" Scathach says with a beautiful yet otherworldly voice "it has been thousands of years since I was last hear".
