"Mom, are you sure of that?" Kim said, while still fapping her dick, "I mean, it's Will, he is our brother..."
Hannah sighed as she held your shaking form in her hand.
"Half, he is your half brother..." She said, her words shocking all three of you so much that both your sisters stopped masturbating. "I need to tell you, girls, something... After I married your father, I met another person, she was a woman, but, she had something... more. A cock, just like you two. Well, sex with your father was just awful, he had a pathetic tiny dick just like your brother, he would cum within seconds inside me and his cum was always weak and watery, the complete opposite of you, girls, and the complete opposite of... mommy's friend".
She made a pause as she sat on the bed. At your place, on the desk, you realized that different from your sisters, your mother had just a pussy. After sitting down, Hannah kicked her feet on the desk, next to you and with a stern voice, commanded you to worship them. Feeling your lips, which were very wet from your tears, she continued her story:
"Well, I started to cheat on your father with her almost every day. All the neighbours and even family members that would see her coming into our house would just think she was just a friend, while actually, she was plugging that big, fat cock of hers deep inside my married pussy. Your wimpy of a father never suspected a thing, or, if he did, he was too much of a pussy to do anything about that."
"Well, since her cock was just too massive and I loved the feeling of her cum sloshing inside me, we never wear condoms or anything. Funny that I made your father wear them even for oral sex... god I was so disgusted by that tiny dick... Well, it didn't take long for me to get pregnant with my big girl here, Kim! I was so happy when she was born, especially because I knew who her progenitor was, and I knew she was going to be as nice and big as her mommy, in every way possible..."
"Since I was too busy with my work as a mother, I stopped meeting with my friend for some time, but I still had to attend my "job" as wife to your father and, Will, that's how you came along" Your mother gave you a disgusted look, just like if she had seen a cockroach.
"At first, I thought about aborting you. I even re-started meeting with this friend of mine while pregnant with you. She even called over a lot of futa friends of hers and we had lots of gang bangs. I was hoping that at some point one of them could crush you with their massive cocks or drown you in their thick cum. But no, I ended up giving birth to you..." After saying this, your mother placed her foot down on you, pinning you to the desk and almost breaking your rib cage.
"Well, after some time, I got pregnant and gave birth to Alice, my cute little girl. I was already planning on divorcing your father, planning on leaving him and Will alone and taking all the money with me, but one day, a miracle happened! I woke up, looked at my side, and saw your daddy, shrunken to three inches, laying on the bed beside me! I quickly grabbed him and called my "friend" over!" with this, Hannah moved her hand towards her pussy and began to masturbate.
"With my friend present, I told your father the whole truth, how 2 out of 3 of his children weren't his, how I hated his tiny little dick, how he was pathetic, how I didn't love him or his original offspring and, most important, how I was going to erase him from existence! Well, after I made him watch my friend absolutely destroy my tight pussy, making him see the kind of pleasure that he couldn't, and never will, be able to give me, I placed him in my mouth and gave my girlfriend the best handjob ever, when she came, she covered that pathetic man on her thick, fertile, superior futa cum and I swallowed him whole!"
"Fuck..." your both sisters said, as they grabbed their cock and continued to move their hands up and down their thick shafts.
As Hannah lifted her foot over your tiny body, you were able to catch your breath for just one second, before her hand snatched you again and you found yourself covered in a weird substance. You quickly realized that it was your mother's pussy juices. Her other hand reached for the cabinet and from a drawer, she got out a massive, 10 inches black dildo.
Rubbing it on the entrance of her pussy for some seconds, she made sure to cover it with her juices, giving the black dildo an even more shining appearance. Placing it on the ground, she squatted and quickly sat on top of the massive plastic dick, feeling how good it stretched her pussy. Breathing heavily, she looked at you and said:
"Well, honey, looks like this is it. Mommy is gonna place you in her mouth and swallow you whole, I want to feel you move in my stomach as I digested you alive. Just to warn you, it is going to be the most painful thing you ever experienced, but, at the end of the day, this is what tiny, pathetic men like you and your father deserve!"
She began to ride the dildo as you bounced on her hands, each movement of her body shocked your whole world and almost made you puke! All you could hear was the wet sounds of your sisters' hands on their cocks and the slapping noises that the dildo made in touch with the deeps of your mother's pussy.
"Girls..." She said, between moans and her heavy breathing, "Come here you two, I want you two to give me your cocks so I can masturbate them and, when you cum, I want you to send your brother to a certain death on the deeps of my stomach!"
As she said that, Hannah placed your crying form in her mouth. The mixed smell of her morning breath with toothpaste almost made you nauseous and looking at the inner walls of her mouth and her tongue, you realized that she was salivating at your taste. Her tongue started to move, flipping you around and pressing you against the roof and sides of her maw, you didn't know if she was doing this just to tease you, or if she was actually tasting your tiny body.
Kim and Alice walked closer to her. Both girls loved their brother dearly, but... "mommy is right, right?" Will couldn't be trusted, also, the sigh of their brother, so weak and pathetic, being bullied by their mother's tongue was extremely erotic. They knew that they were condemning their brother for one of the most painful and humiliating executions possible, but they just didn't care.
Hannah began to gently stroke her daughters cock's, rubbing gently her fingers on their heads, using the precum that was oozing out as lubricant, and pulling it all back down to their crotch, making them shout long, throat moans. You looked at your gigantic sisters with fear, pleading with them for help, you tried to scream, but your mother's tongue assault didn't stop until she said:
"Girls, momma is gonna cum! Please, tease your brother a little bit!"
She extended her long tongue out, with you placed on it, drenched in her spit from head to toe. You had a clear vision of your sisters' bodies now, as they loomed over you like goodnesses that had just condoned you to an acid hell in your mother's belly.
"I am sorry... Willy" Alice said, moaning as she looked at your tearful eyes with her lust-filled ones, "I am going to make good use of your room, going there every day to masturbate in your memories! I am going to paint that fucking walls white with my cum as I think about how painful and how desperate you must be inside mommy's stomach! Goodbye, big bro!"
"Will..." Kim said, as her face began to turn red, "To be honest, I really wanted to... Shove you inside my dick, and digest you inside my balls, but this is very hot too! I am going to grab some stuff from your room, before Alice cum all over everything, what isn't cool I am just going to sell online, hope you don't mind! Also, don't worry about that cute girl from school that you had been crushing on, I am going to bang her brains out and maybe name one of our kids "Will" after I knock her up!"
Staring at the two behemoths in front of you, your whole body almost went numb. Maybe it was from the fear or shock, but you just felt nauseous and weak, unable to move a muscle. Soon, you heard your sister moaning even more loudly, and you knew what was coming...
Your mother's whole body began to shake as she orgasmed on the dildo stuffed into her soaking pussy. She squirted all over the floor moaning, driving her daughters over the edge. Alice and Kim came almost at the same time.
Ropes of cum reached for you in slow motion, the first one, hit your mother's cheek, then another one flew over her head, and then, they started to cover you. Your vision first got a little bit fuzzy, with a white layer covering your eyes, then, your whole world turned white sticky as more and more cum started to flood inside your mother's mouth. Your nose and mouth burned as the cum invaded both, and the weight started to pin you on your mother's tongue as she started to move it around, tasting her daughter's milk. You still were able to see some light under the thick layer of cum covering you, until Hannah shut her mouth and involved you in darkness.
