PART 1: How it all started?
[ Mom straightened up, licking her lips slowly, savoring the last traces of the forbidden family cocktail—my cum, Kiara’s arousal, Leo’s saliva, all layered with the invisible imprint of her own guidance and Xoe’s longing.]
(I am sorry, because this chapter got huge, just like your Mom. This chapter will come in 2 parts as I didn’t want to miss out anything because it’s so fucking hot to know in such detail how a family fucks for the first time! That’s why I didn’t wanted to keep it short. But I think it will be fucking worth of your time!)
“Mom let’s cum together!” I moaned into her lips as we both are sucked together so hard by our respective same gendered partners.
“As you wish my son, let’s cum together in 30 seconds my darling. anhh!” She said biting my lower lip and then we both just groaned at each other’s faces with our hand on each other’s neck, our foreheads and noses pressed and lips brushing as the oral get more and more intense.
Mom’s nails dug into my neck. Mine into hers. Our bodies arched in perfect sync.
“Three ... two ... one...”
We shattered together, exactly at the same time. Well, we mother-son definitely have a deep bond that we can sense when the other is about to cum.
Leo’s mouth again filled with my thick load but this time spilling all over his face and lips, while Kiara’s mouth also got filled with mom’s sacred cum and her face wet with mom’s squirt. Leo and Kiara look at each other with cum filled mouth and leaned forward into a kiss. Cum and squirt mingled on their tongues, sliding from one mouth to the other in thick, glistening strands that broke and reformed as they kissed deeper. They both didn’t touch or even kissed each other, they just pressed their lips together to exchange, to taste our release together. They swapped everything—my seed, Mom’s release, their own saliva and my chocolaty dick taste—until their faces were a shared mess of white and clear, dripping down chins and necks in lazy rivulets.
“Mom you’re still dripping.” I said watching her pussy with the intention to eat it.
“And there’s still cum stuck on your cock, my son.” Mom said with the same intention as mine.
We both slip past Kiara and Leo, with them continuing their cum exchange treaty, and laid down on the sofa cum bed near the dining room. We didn’t even need to tell each other what position we will lay down in, directly got into 69. I began to lick her sacred pussy and inner thighs, at the same time mom began to suck clean the cum from my dick, both laying down sideways. We didn’t want to cum again so just after cleaning each other quickly in 20 seconds, we again went to kitchen where we saw Kiara and Leo finally standing up and gulping every liquid they exchanged and consumed.
“My my, look at you two, so hungry! Now you both go and get a shower; we still have our breakfast pending you know.” Mom said pushing down her dress.
As mom mentioned shower, Kiara began to look at Leo, “Hey don’t get the funny idea, we are not showering together, have some shame! I am a 100% gay femboy who loves dicks only.” Leo said stepping back making his hard dick wobble.
“Huh, really? Then why were you so horny to taste your mom’s squirt from my mouth? You explored my whole mouth and your cute dick jumped when our tongues tangled.” Kiara teased Leo with a smirk and raising eyebrows.
“Oh honey, I tasted Mom’s squirt because it came out of the same holy place that made my favorite cock. Doesn’t mean I want your pussy. It means I’m greedy for anything that’s marked by family. Also, it’s my mom, why wouldn’t I want to taste her and especially mixing it with my brother’s load” He smacked his lips as if describing his favorite food.
He leaned in even closer, breath warm against her ear, so only she could hear the next part.
“But don’t flatter yourself, princess. My dick jumped because your tongue felt good tangling with mine—slippery, eager, still coated in my brother’s load. That’s the only hole I’m interested in right now ... and it’s not between your legs.”
Kiara’s eyes fell down to his dick in defeat.
“Shower’s all yours, big girl” he called over his shoulder without looking back. While Kiara looked at us chuckling after getting humiliated like a child.
“Hey, you know what Noah after a good look I realized that your little brother and you have the dick of same size! And his is cuter that yours.”
“Yeah, that’s the one thing I am both ashamed and proud of!” She then walked away towards the bathroom stomping her feet in anger for laughing at her. And now my mom laughed at me slapping my semi-hard dick like a spring teasing me like the same cock didn’t make her scream my name so many times.
After 10-15 minutes, everyone got ready and refreshed, except Xoe she’s still asleeps. Mom in same sexy wine silk robe, because she just got dirty below her hips which I cleaned good. My dick is also clean though, Leo didn’t let my cum fall on my legs, he’s a good little brother and also mom’s mature mouth sucked all the extra cum pretty good.
I wore loose grey sweatpants that hung low on my hips, paired with no shirt—my toned chest still marked with faint red scratches from last night (Xoe might not be with us but her presence is always there, so cute). Leo slipped into tiny black booty shorts that clung to his plump ass and thighs like a second skin, the thin fabric barely containing his semi-erect dick, topped with an oversized white crop top that exposed his smooth, narrow waist and flat belly along with his long-wet hair making his face look so soft and girly.
Kiara changed into a fresh tight wine crop top that hugged her heavy breasts, nipples poking through the fabric, and a short white-brown pleated skirt that barely covered the tops of her thick thighs, paired with sheer black thigh-high stockings that accentuated her curvy legs.
We all sat down together in the same seating as we were the yesterday night for dinner, but now with totally different energy. Funny, how quickly time changes.
As mom was setting up the plates and bringing breakfast, Kiara leaned forward, elbows on the table, her wine crop top straining as she fixed her gaze on Mom, then me, voice low and husky with curiosity.
“So ... when did this all start? When did you first taste your own son’s cock, Meera? Or when did Noah realize his mom’s pussy was the only one that ever felt like home?” After taking a little pause letting mom sit down, “And also Noah, when did you realize, you like to grind your dicks with Leo and what about Xoe, what did you even managed to seduce her kind!? Kiara asked jumping on her chair like a child who has just started to realize that his or her genitals, does much more than just peeing.
“Oh Kiara, it didn’t start with a bang, darling. It started so slow and steady that we didn’t even realize when we all began fucking our blood!” Mom leaned back into the chair falling behind bulging out her heavy breasts.
“Let me take over this conversation, because I am the fucking root of all this, that started this incestuous chain, which I don’t regret at all. And the revelation I am about to do, only mom knows about it!” I leaned forward on table with my elbows while mom smirked remembering something, “Oh my baby, are you going to reveal your past? The past you told me about when we had such an amazing sex on my birthday while your father was just next door!” Kiara bit her lip just by the thought of us.
“Yes mom! And not just mine, we should all reveal our pasts because I think it’s a good time” I squeezed Kiara’s inner thigh and caress mom’s and Leo’s feet with mine.
“My story begins at 11, when I first fucked a 13-year-old girl [My Milf Aunt’s Gothic Daughter’s Friend (Their part will come in the upcoming chapters soon!)] in the attic during a family gathering—her tight, curious pussy clenching around my boy-cock while everyone laughed downstairs, thinking we are just innocent kids playing together. By 15 I had seduced the neighbor’s thirty-something wives, then the school nurse, fucked every hot girl in my school whether younger or older, my teachers or whoever crossed my path. In just 2 years, my body count reached around 250. But normal sex grew dull fast—the moans too predictable, the bodies too ordinary. I craved something forbidden, something that burned with real risk and raw intimacy. That’s when I looked at Mom’s voluptuous hourglass figure, Leo’s soft girly hips and thin waist, Xoe’s sharp dominance and perfect curves ... and realized blood was the only thing left that could still make me throb like the first time.” Leo is already stroking my cock with his foot while eating custard, mom enjoying my feet caressing her inner thigh and her cappuccino and Kiara, she is so concentrated on me that she forgot to eat.
I took a strawberry between my lips and fed her, we were chewing the same strawberry together and then I continued, “So the first ever time my cock hardened for family was for my mother.” Mom leaned forward, her silk robe slipping further to reveal the deep valley of her cleavage and looked at me like she was proud of me.
“One evening, she walked into my room while I was studying. She was wearing that cream colored thin, silk nightgown. She bent over, facing me to pick up a book I’d dropped, and in that split second, the air in the room shifted. I didn’t see a mother anymore; I saw a woman, vibrant and desperate, whose thin waist is arched with her huge heart shaped perfect ass above her head and her huge boobs hanging down revealing that large cleavage right in front of my face.”
I stood up from the chair and went closer to mom to sit on her lap facing her. She welcomed me making space for me, cupping her tits I continued, “That was the moment I made an unwavering resolve, I want to fuck my mother!”
Mom kept her warm hands on my hands, which were cupping her breasts and made me squeeze them harder, “My baby, I loved how a simple act of bending down fucked the entire future and dynamics of our family!”
I moved my lips closer to hers, “I didn’t act immediately. I waited. I watched her posture, the way she moved, the way she sighed when she thought no one was listening. I started leaving small, psychological traps—lingering touches on her shoulders, standing just a bit too close in the kitchen while my father watching us but too oblivious to notice his son’s intention towards her wife, but I noticed, touching her in front of someone who knew we are mother-son gave me the most reaction. I started going gym to tone my body, started wearing tight shorts to show off my big bulge and began to compliment about her body and figure in an indirect way. I was grooming her to need my attention, to crave the way I looked at her.” I grind my bulge on mom’s stomach making our lips brush softly and her tits flat on me. Leo and Kiara are listening to me with the most unbreaking concentration.
“And after 6 months of continuous and slow attempts of seduction, I finally began to see difference! Mom started with the indirect invitations, she’d ‘accidentally’ brush her ass against my cock while passing through the hallway, her fingers lingering on my bicep longer than necessary. Every interaction was a test. I’d challenge her, push her boundaries until she was breathless and confused, not knowing where her duties as a mother ended and her desires as a woman began. Then after 2 more-month mom started to wear sexier and seductive clothes ... mmphhhh” Mom captured my lips in a slow kiss stopping me mid-sentence. Then she said with our lips still pressed.
“Hey, your side of the story ended. Wouldn’t it be right for me to tell how much your mother got seduced by her son and how she seduced him back?” She said kissing me tighter.
“Yes, yes please. I want to know. Meera, please stop kissing your son and reveal how you seduced him back!” Kiara said jumping her ass on the chair making her boobs jiggle.
“Kiara darling, but Noah is forgetting about Leo in this whole story isn’t it right? In the amidst of those 6 months when he was trying to seduce me, Noah accidentally seduced someone else in this family too.” Mom said looking and Leo’s hard cock wanting to tear the already tight shorts. Kiara bit her lip reminding herself the moment she saw our dicks grinding the first thing in the morning.
“Oh, how could I forget my delicious little brother? The one who turned me into a hungry, half-gay addict and unlocked the truth of just how incredible another boy’s cock can feel especially when it’s your own blood. While I was busy hunting Mom, I didn’t realize Leo was getting hunted too, watching my bulge with those thirsty eyes, just to see his own cute dick jumps for his brother.” I stood up from mom’s lap and stood in front of Leo with my erect sword, sheathed in my pants poking his cheek. “I am a little proud to say that Leo managed to seduce me into liking his cock, even though he was only 13 at that time. Well, he is my brother!”
Leo turned his head, sucked and kissed my tip with his soft lips and then stood up, pushed his cock into mine, a hard, rhythmic thud of flesh on flesh, and the sound of it made Kiara’s moan, her fingers beginning to work deep into her folds, watching brothers worship each other’s anatomy.
“Brother, do you want to know my past, how badly you seduced me even if it was not your intention?”
I kissed his lips tightly, “Tell me everything, how you made me crave my own brother’s touch and made me half-gay for you.”
As we were going for another brotherly kiss, Kiara interrupted, “Wait, first just explain me what the fuck ‘half-gay’ even mean?”
Mom stood up and grabbed both our cocks, squeezing it hard together making it a single piece of meat, “Darling it means, Noah wants fuck another boy, but won’t allow to get fucked. He will not in any way wants to suck or get fucked by a cock. And also, if that boy looks girly enough, he will fuck them.” Kiara’s eyes met Leo’s as if they both got a thought struck in their mind through a connection of cosmos, but I was not able to notice it because I was too busy with mom, staring into her seductive eyes, “Mom, you know me so well!”
Mom dragged us both from our frotting dicks together like playing games on joystick and lead us to the same sofa-cum bed where me and mom just had our little session of 69, “Now you both sit here, grind your cocks and tell us your seducing past.”
We both locked us in scissoring position (yes, for maximum cock-on-cock and balls-to-ball contact) while Mom and Kiara bought chairs, sat down close in front of us to enjoy us like a movie with mom’s fingers caressing Kiara’s clit slowly. But as you know the rule, she can’t caress mom’s ‘sacred pussy’ back, so Kiara, respecting mom’s pussy, just placed her hand on mom’s inner thigh.
“I was 13 when I first realized you weren’t just my protector; you were my obsession, when once you were hard for mom and in the hallway your hardness accidentally grinded on my soft ass. From then, I began watching you, coming home from the gym, the sweat on your seductive body turning your shirts transparent, that bulge constantly straining against your shorts and I’d ache to taste the salt on your neck and lips. I began to train my glutes and thighs just for you. You also seduced me psychologically, Nu. Your charm, confidence and that show of your body, even if those were targeted towards mom made me so hard for you and I realized, how hungry I am for my brother’s cock and body.”
We both shed our pants, our cocks sprang forward, twin pulses of heat clashing in the open air, the naked friction of grinding our cocks and balls together with a heavy, wet rhythm that filled the room with heat and mom’s fingers and Kiara’s moans became faster and louder, “I became clingy, intentionally. Every time I hugged you or got close to you, I made sure that you grab my thin waist, grip my plump hips, feel my smooth girly skin, rub my inner thighs and grind our crotches. I began to dress tight and more girly; I wanted you to feel how good a femboy dick and body can be. And after 3 months, you stopped pushing me away. You’d just hold me tighter, thinking it was just your cute little brother, but I felt your cock twitch every time. That was my first victory.”
Leo gripped his fingers on our frotting cocks and began stroking it and I gripped his thin little neck enjoying listening to a story of how I got seduced by my little brother while getting stroked by him. “Then finally the day came. We were just having a brotherly wrestling match on your bed—laughing, rolling around, pinning each other like we always did when we were kids. Except this time, I made sure my shorts rode up high, my ass grinding back against your crotch every time you ‘accidentally’ flipped me over, or every time I sat on your lap to pin you down! You always won the fights but I won the war.”
He squeezed our cocks harder on the upstroke, thumb circling the heads so precum smeared between us. “I was on my back pinned by you on the bed, my legs wrapped around your waist, my hands pinned on my sides by you, my shirt riding up showing my slender waist and then our erect cocks pressed together. I began to grind as we got locked in that position, you froze. Then you growled ‘Leo, stop moving like that. Its w ... weird’ But your hips betrayed you; you rocked forward, grinding deeper.”
