Turning in

I walked past my room upstairs, closing the door so the girls wouldn’t see me absent. If anyone thought I’d sleep alone in my room when I had one eager and sexy slut waiting for me in her bed then they seriously needed a shift in priorities. Seeing a nearby door almost entirely closed I peeked inside. Holy fuck!

Tori was stuffing her face with a dildo, shit it even looked like Mom’s not so secret dildo! The girl must have stolen it and was now watching her laptop that was playing pornography, imitating the enthusiastic scene before her before pausing, rewinding and trying again. Tori was blunt, and to some degree a hard ass. But when it came to school work or competitions she was a perfectionist. Seemed like my “eager to please” program was mixing with that side of her to make her obsessed with being perfect at sex. Well, let’s not go too far. Hearing her gurgle I knew she at least was perfecting blowjobs. My dick hardened imagining a porn plot where I walked in and offered my dick for practice.

Her handjob was passionate, horny and sloppy. The program was doing serious work but it was taking way longer than it was with me or Mom. Last thing I wanted was to scare her off before she was fully into the program. I watched for a few more moments, admiring how into it she was getting. How hard her nipples were through her shirt, I could smell her arousal from outside.

I jumped suddenly and backed from the door. I though I heard a sound! Listening carefully another high pitched sound came from Lauri’s room. Weird. Walking I peeked in and covered my mouth to stop my gasp from alerting her. Where Tori’s changes were like a roller coaster, having big and exciting moments but otherwise normal, Lauri was all curves now.

I watched in awe as my once flat and boring sister was posing in the mirror shyly. Turning occasionally to see her new body. I saw it slowly growing during dinner, it must not have stopped. The “serious tits and ass” program wasn’t lying! That’s for sure! I was curious now. The program for Tori was changed and moulded to fit her and her perfectionism. What part of Lauri would this synergize with?

What else did that program say? A full evening of passionate fucking really turned the day into a blur. It would give her incredible curves that would be super sensitive and demand attention. She would enjoy showing off. What else? Make her more uninhibited, horny, and open. Before long my shy, flat sister would be a bombshell tease flaunting her stuff and loving the show.

Even now by herself, she was posing slightly. Showing off how her breasts bulged in her much too small bra, and how her panties stretched to her new volumous ass that now competed with Mom. I felt myself harden and I eventually **** myself from her doorway and began heading to the next bedroom.

Opening the door I smiled. I loved my Dad, and I missed him dearly, but I couldn’t help but admit how he was a total cuck bitch. How he didn’t use this program to save their marriage was beyond me. Mom was completely obsessed with my dick! Sitting on her knees on the bed she wore a white lingerie set that stood no chance against her incredibly curvy body. Straps connected white lace, see through stockings and she tied her blonde hair into a perfectly straightened ponytail. She looked over her shoulder, ass facing the doorway, “Mhmm baby, I miss that fucking cock! Wanna take her place with her in bed? Stuff my pussy with more of your baby batter?” She slapped both her ass cheeks and moaned, “Come take your place as my man and knock me up!”

Shit! After this she would no longer be my Mom, she would be my bitch, my partner, my cumslut. This was my room and my bed. She was mine and sitting there, offering herself to me. Sorry Dad, but you had your chance! I began taking off my shirt, amused how eager she was. We were just watching tv ten minutes ago while getting each other off and having her blow me. Maybe an hour since we fucked on the couch. She was insatiable!

I began to undo my pants, enjoying the intense excitement on her face watching my hands intensely. “Took a peek on your daughters. They are slowly becoming curvy sluts just like you.”

I meant to tease, to humiliate, maybe even gloat but she only moaned, teasing her pussy through her panties, “Fucking finally! I can’t stand them right now! God I wanted to kick them out during dinner and **** myself on your monster I was so bored! They can’t read a room!” My pants fell and she let out an excited gasp and giggle, wiggling her legs under her, “Like you’re obviously the stud of the house! They should be way more respectful and submissive! So prude, boring, disrespectful. I don’t want to admit it, I am their Mother…but I hate them!”

Jesus, at the beginning of the day she doted on all of us equally. Adoring her children and was a selfless compassionate woman. Now she was in heat, all of her love and affection focused on me. It seemed if they weren’t like her she just saw them as in the way.

Mom watched me drop my briefs and her eyes went from excitement to lidded with pure lust. “Ohhhh I can’t wait until they become complete cock lovers like me. Begging on their knees for your next load. Licking your mess from their freshly fucked pussies! God! It turns me on so much! They’ll make such good sluts!”

I laughed and approached her, placing a finger on her plump lips, “Not too loud, Mom. Don’t wanna scare them off too soon!”

She looked up at me, kissing my finger, “Erika…I’m not your Mother. I’m your lover, your personal bitch. Start treating me like one.”

I smiled, “Alright…Erika…suck my fucking cock!” Erika moaned and bent down making it my turn to moan standing beside the bed, feeling my legs grow weak at her expertise. I don’t think I would ever find a woman with this level of enthusiasm normally. I wondered where the genius who made these programs were. I looked down and admired how beautifully her lingerie framed her gigantic ass while she sloppily gagged on my member, if she wasn’t knocked up from all the times before…I was making sure of it tonight!

The night got wild, no longer seeing each other as Mother and Son but Master and Slut really changed our dynamic. Her earth shattering orgasms and moments of much too loud screaming and moaning were proof. I must have dumped five loads in the horny babe but I was too busy to notice one important detail…Tori watching from the doorway, cracking it open. If I did I might of noticed her typing a storm on her phone and recording some of it in one hand, her fingers taking herself with the other.
