Katie's Family Falls

Katie has 2 sisters, Amy and Leah, and a brother Steven. Her mother Donna is a single mom having lost her husband to the war in Afghanistan. Her husband's military life insurance paid off the house and still left a good amount for the children's college fund. Amy and Leah are fraternal twins and polar opposite. Amy is 5' 7", blond, with porcelain skin, and with a lithe body like her mother. Leah has an athletic built, long auburn hair with a darker skin tone than Amy and is 5' 10 ". with her height and darker skin tone inherited from her father. Both girls are highly intelligent with both on the honor roll at their school. Steven is brunette his skin tone close to Leah's, and an athletic muscular body and 6' 4" tall. Steven has lettered in football, basketball, and baseball in high school. Amy and Leah were not into sports but gravitated toward the arts, music, drama club, debate team, and Latin club. Needless to say, Donna was very proud of her children and sadly wished her husband, James was here and part of their lives. She had cried herself to sleep many nights wishing that.

Sarah, Katie, and I (I am going to name her Paula) after several hours of intense sex, stopped for a break and talked about what they were going to do next. Katie spoke up, "we could go share Lilith's gift with my family". Sarah and Paula agreed with her saying after her family, they could change Sarah's family. The 3 demons dropped from Sarah's 2nd story room window. Dropping their glamour, the 3 took flight towards Katie's house. Katie's mother Donna and her brother Steven were home. Amy and Leah were at a friend's house studying for a math test. Donna was watching TV and Steven was in his room doing homework. Landing on the side of the house the 3 succubi switched into their human glamour. All 3 wore very tight yoga pants proudly showing their camel-toes and their exquisite derrieres. There was NO outline of underwear as all 3 were commando. Their tits were barely covered by a very thin tube top barely covering half their large tits with excessive cleavage and exposed tit flesh showing. Long thick nipples pocked out of the thin material proudly. Looking herself over, Katie said, "do I look sluty enough", to Paula. Paula smiled saying, "Yes, I'm impressed, you have turned out to be a slut after my own heart". Paula's complement sent a gush of pleasure straight to Katie's pussy resulting in her becoming even wetter.

The 3 walked to the front door entering the house. Walking by the living room where Donna was watching TV, Katie introduced Paula as a new friend. Donna shot off the couch when she saw what her daughter was wearing. "Katie Jane Donaldson, what the hell do you think you're doing dressed like a SLUT", Donna shouted at her. Smiling, Katie's hips swaying provocatively walked towards her Mother. Throwing her arms around her mother's neck and shoulders pulled her in for a deep french kiss with her tongue spreading her corrupting saliva around in her Mother's mouth. Donna fought strongly for a few seconds trying to break free of Katie. But the darkness quickly spread throughout her body quickly eroding her resistance. Soon she was returning Katie's kiss with their tongues battling for dominance. Breaking the kiss for a second, Katie asked where her brother and sisters were. In a fog from the beginning corruption, Donna said, "your brother upstairs studying and your sisters are at Crystal's studying for a math test". Katie said giggling, "why don't you two go upstairs and surprise Steven". Paula and Sarah gave Katie a "thumbs up" sign and headed up the stairs. Turning back to her Mother, Katie pulled off her top and guided her Mother to her right nipple. Cooing Katie said, "suckle my milk Mother and you will feel so wicked like I've become". "I can't wait till you all transform into hellspawn like me and Sarah and it's all because of Paula". Just those thoughts resulted in Katie having an orgasm squirting a large bolus of girl cum into her shorts. Katie savors the feeling of the orgasm and her soaked shorts. She envisioned in her mind what her family would look like as hellspawn. This causes her to orgasm again only harder. Katie begins to undress her as her Mother continues to suckle. Suddenly there is a shout from upstairs, "WHAT THE FUCK", her brother shouted. The voice was quickly cut off as Katie heard bodies hit the floor. Smiling, she finished undressing her Mother and then dropped her glamour. Donna had drained one breast and Katie had switched her to the other. By this time the darkness had spread throughout Donna's body and her soul was screaming for her to fight the darkness. But her pleasure centers were kicking in releasing endorphins as Katie fingered her pussy and rubbed her clit. Katie lower Donna to the floor scissored her and began to trib her. Katie's longer clit rubbed against Donna's clit already much more sensitive due to the consuming darkness. Donna moaned deeply, "Oh baby, that feels so good as I haven't had anyone touch me there since your Father died". Katie increased her pace driving her Mother insane with pleasure. Donna thrust her hips upward in a grinding motion to bring her clit more in contact with Katie's so the sensation of pleasure would be increased. While tribbing both women were massaging each other's breasts, sucking, flicking, and pinching nipples. All of this activity fueled each's building orgasm. Katie felt she was going to explode from the building orgasmed which caused her to revert to her true form. Donna was so far gone in the pleasure that Katie's changing into her true form did not phase her. Just as she thought she was going to be consumed by her orgasm, it STOPPED. "NO, NO", she screamed. "Why can't I cum, why can't I cum", she screamed again. Leaning over her Mother's face, Katie said, " you have got to give me your soul to cum Mom". Donna screamed, "take the fucking thing, I need to cum". With that, Donna experienced the most powerful orgasm of her life and her last one as a human. Her heels and head dug into the rug, her back arched at an unbelievable angle as her body went catatonic. She remained like this for over 60 seconds, suddenly with a sigh, she relaxed collapsing on the floor out cold. Katie knew how her Mother felt experiencing that last orgasm as a human. She had felt the same when Pauls and Sarah had turned her.

Donna began to transform. Katie watched her Mother transform while fisting herself and rubbing her clit. Lips, areola, nipples, and labia turned pitch black. Ears thinned out at the top becoming pointed while her tongue lengthens becoming forked like a snake's tongue. 3' fangs replaced her canine teeth. Crimson skin color quickly spreads from her sex to her entire body. Eyes go from blue to 2 black orbs with red serpentine pupils. Her already feminine figure only got better as her waist narrowed, hips widen, and her derriere became rounder and more toned. Her height grew to 6' 2" with added muscle mass to match her new frame especially her pecs and trapezoid muscles. Her new pecs supported her new EEEs and enlarged trapezoids to support her wings and fly. Donna's transformation concurred with her 6' cocktail, 8' wings, 7" horns, claws, and dewclaws growing in.

Looking over her new body, Donna said, "not bad, not bad at all". Walking over to Katie, she grabbed her kissing her, and thrust her cocktail into Katie's pussy. Katie moaned in pleasure as she returned her Mother's kiss and thrust her cocktail into her Mother's pussy. Running through Donna's mind was the turning of Leah and Amy as she knew Steven was being transformed upstairs in his room. This triggered a powerful orgasm squirting girl cum all over Katie's crouch, rug, and floor. "Jesus, Mom, you just soaked my crouch", Katie said giggling. "Hey, I can't help you made me a slut where every dirty thought triggers an orgasm" retorted Donna giggling also. Hugging her Mother close, Katie whispered, "I love you Mom". Steven, Paula, and Sarah came downstairs in their demonic forms. Steven was a 6' 10" Incubus with a powerful muscular frame. But what got Donna and Katie's attention was his 14", 4" thick cock with large grapefruit-size balls. Steven was stroking himself smiling at his Mother and Sister, "who wants to be the 3rd to ride my new cock". Paula and Sarah had huge smiles on their faces.
