[You’re all ... you’re fucking each other. Your own family.]
I rang the doorbell of my house with my hands holding my girlfriend’s hand, our fingers interlaced. Today I (18) am introducing my girlfriend, Kiara (17) to my family after 3 months of dating and fucking her. As we waited quietly on the porch for the door to open, I squeezed her hand and smiled at her to calm her down, I could feel she’s nervous and shy. Though I have already told her not to worry so such, my family is very friendly, affectionate and very open minded but she is going to discover the true meaning of those words soon.
The door opens with a click sound and my mom, Meera (42) greets us with a happy and excited smile on her face. My mom stood before us with her voluptuous and milfy figure wearing tight white halter-neck gown with high thigh slit dress hugging her huge curves and thin waist, showing her thick milky white thighs. Her necklace stretched deep down into her soft cleavage and her silky black hair tied in a messy bun.
She stretched out her arms to hug Kiara, “Oh my, you are so beautiful Kiara. Even better than what Noah described. I am so happy to finally meet you!” Mom put her one hand on Kiara’s waist just above where her hips curve and one on her slim neck with her thumb brushing her blushing cheek. Kiara is wearing a tight white top tucked in her high waisted black skirt just enough to cover her ass cheeks and a pair of black stockings just above her knees showing her smooth juicy thighs. Her purple hair falling to her length of her plump hips and bangs on either side falling on her curvy boobs. She does not like to show cleavage despite having such huge milkers (obviously not larger than my mom), she is more of thick thighs show off girl.
Kiara also tries to match mom’s energy and places her both hands on mom’s thin waist while looking slightly above into her eyes as their soft breasts squeeze together, “And you are much hotter than Noo described. I now realized why he doesn’t stare at other girls when he has such a beauty under his roof itself!” She chuckled a little shyly.
“Oh my, Kiara, you definitely have a way with your words, so flirty and nice thing to say.” Mom softly pulled Kiara’s waist and neck closer and gave her a kiss on cheeks just near her side lips making their boobies flat into each other. When they bounced back, Mom gave me a seductive look and hugged me tightly squishing her huge soft boobs on my slightly muscular chest.
“I am very happy for you Noah; you got such a nice, beautiful and flirty girlfriend.” She leaned back from the hug but stopping right when our noses touch and our lips brushed a little with her milkers still squished on my chest. Her hands are placed on my back while I slide down my hands from her thin waist to her ample hips. As I slide down my hands on my mom, I noticed a little twitch of shock on Kiara’s eyes and forehead, “Now you both go and get a tour of “Noo’s” room. I will prepare some nice hot dinner for you both.” Mom pokes my nose as she teases me with my nickname Kiara had given me.
Then suddenly Mom and I closed the distance between our faces and our lips. The closer we got the bigger Kiara’s eyes got out of shock. Finally, we gave each other a tight loud smooch on the lips, the sound of which made Kiara shudder. Me and Mom then pulled back our lips with my hands giving her ass a little squeeze and jiggle.
As I got separated from mom, my little brother, to be more precise, my cute little femboy brother, Leo (15), came out of his room wearing a tight black crop top and full-length loose grey sweatpants in which his smooth feminine slender figure and thin waist are enhanced. Through the grey sweatpants his plump curvy ass and his semi-hard cock dangling are bulging out (yes, he is not wearing underwear). He has silky shoulder-length girly hair making his neck look even thinner, so easy to grab and kiss.
He saw me and Mom getting separated and begin to walk near us, “Whoa, I heard a loud smooch, bro are you and mom again makin-nngg.” He stopped mid-sentence as soon as he saw Kiara hidden between me and mom. “Oh hi, I think you are Kiara, right? Hi I am Leo, Nu’s brother.” He said in a soft tone raising his hand for a handshake trying to compensate for what he was about to reveal. Kiara shook his soft slim hand while her mind thinking “Making what? Making out!? And again!!?? With his blood related mother!!!???” She has so many questions to ask, so many things to experience yet about this family. While mom gave a naughty smirk and walked to kitchen to prepare dinner. “Hey Leo, it’s so nice to see you and umm ... you are. You look so cute!” She says calming herself a little, trying not to explode.
Leo then looked at me with his seductive eyes and bending forward a little aching his back, his eyes checking out my big, hard bulge in my pants because of Mom’s wet smooch, “Wow, bro you really pulled a gorgeous lady. I already like her; she is definitely our family’s type.” He once again looked at my bulge with even more seduction. He is not even trying to hide which Kiara caught but she maintained a forced smile on her face trying not to think of it, as what she is thinking.
“Yeah Leo, even I can’t believe sometimes that this gorgeous lady got impressed by me.” I said putting my hand on Kiara’s waist noticing his semi-hard cock getting hard slowly the more he stared my hard bulge. Leo turned around hiding his excitement inside his pants and began to walk to his room swaying his cute curvy hips. He turned his head, “If you need anything I am in my room as always, waiting.” He winked at me and then shut his door.
I looked at Kiara who is standing like a statue, wrestling with her thoughts. I spanked her ass lightly, “Wanna see my room?” I pulled her closer to me from her waist, my lips brushing her ear, “Don’t you want to see my bed where we both will be fucking and explore our kinky fantasies together from now on?” Hearing that Kiara got horny pushing me a little with a naughty smile maintaining her shy personality, “Hey, your mom is right there. And yes, I want to see your room, especially your bed. I want to inspect if it’s of correct height for you to rail me in doggy style.” I pushed her with my shoulder giving her naughty smile back and we both headed to my room.
I know Kiara very well, whenever she begins to doubt me, I just have to talk and act dirty with her. To be honest I chose to make her my girlfriend because of a very specific purpose, her dark and deep fetishes and desires! Well, you know what they say, shy girls are the horniest ones with weirdest fantasies. Not to brag but I am a psychology student and a great student which you will get to know as you get along with me further.
As we entered my room, before even locking the door, Kiara jumped on my bed, sat on her knees bending down in doggy style. She arched her back with her thick ass above her head, her skirt covering half of her ass now. The sight of her thin waist with such thick ass and her boobs hanging down pressing flat against my bed, even though they are fully covered, turned me on so much. My already hard dick became even harder. I went behind her, grabbed fragile waist and began dry humping slowly. As I begin to remove her panties, she turned around, “Hey let’s keep it dry, I don’t want to get wet before having dinner with your family. It will be weird.” I put back on her panties and instead began to grind my cock hard against her ass through our clothing. The bulge in my jeans is perfect fit for her ass crack. Watching those hanging boobs jiggle, I turned her around making her wrap legs around my waist and then dry humping again, but this time grinding my hard as fuck cock on her vagina. We both stared into each other’s eyes with my hands fondling her tits, then we closed the distance between our lips and began to make out aggressively but quietly.
After about 30 seconds Kiara asked pulling back a little with heavy breathing, “Hey are you wearing a strawberry flavored lip balm, because I am not?”
I stopped for a moment and licked my wet lips, “Ah this, no I am not wearing any, Mom was.”
Kiara suddenly remembered her forgotten thought that how I and Mom kissed each other’s lips. She paused for a second, “Amm, well you know..., do you..., you and your mom always kiss each other, like that on lips?” I could see her hesitation but also curiosity.
We both broke our dry missionary and sat down close with my hand on her inner thigh, “Everyone has different way of showing love to their moms and our way is kissing. It’s like normal for us now and we both like it, it makes us both feel loved that way.” I tried to comfort her but I don’t know how she will react when she will discover the real relationship I have with my mother.
She, not yet convinced as she heard the loudness and tightness of the smooch which was way beyond a mother-son-loving-kiss even on lips, tried to ask even more details about it but luckily mom shouted from the kitchen, “My lovebirds, dinner is ready! Come down fast.”
I gave Kiara a soft kiss on her lips before going down. We walked down the stairs hand in hand. Kiara’s palm was slightly damp; I could feel her pulse jumping under my thumb. She hadn’t said another word about the kiss since I shut her down gently, but her eyes kept darting to my mouth, like she was still tasting strawberry and trying to decide if it disgusted her or not. I am obviously going to tell her about my “love for family” but why not show it to her first.
The dining table was already set: dimmed lights, candles flickering, a spread of creamy pasta, garlic bread, roasted vegetables glistening with oil, and a tall bottle of red wine already breathing.
Leo was already seated, legs crossed under the table, still in his loose grey sweatpants and crop top. His hair was tucked behind one ear, and he was slowly twirling a fork like he was waiting for a show.
“Finally,” Mom purred, gliding over to pull out Kiara’s chair right beside. “I was starting to think you two got ... distracted upstairs.” She gave me a knowing wink as she said it, then leaned down to kiss Kiara’s cheek—slow, lingering, lips brushing skin longer than necessary. “Sit, sweetheart. You must be starving after all that ... energy.”
Kiara sat, cheeks pink, smoothing her skirt nervously. I took the seat to her left, immediately resting my hand high on her inner thigh under the tablecloth, thumb stroking lazy circles.
Mom raised her glass with her huge boobs and cleavage resting on the table, “To the new face at our table,” she said warmly, eyes locked on Kiara. “And to keeping things ... close. Really close.”
We clinked. Kiara took a small sip, then another. The wine was strong; I’d watched Mom pour an extra generous measure into her glass. Obviously she has to get drunk before we can reveal our reality to an outside and my sexy mom know how to begin that.
The first few minutes were surface-level: compliments on the food, how pretty Kiara looked, how lucky I was. Then Leo leaned forward, elbows on the table, chin in his hands, staring at Kiara with big, innocent eyes.
“So, Kiara,” he started sweetly, “Do you like being the center of attention? Because you’re definitely the main course tonight.”
Kiara laughed, a little too high-pitched. “Um ... I guess? I mean, thanks?”
Mom smiled indulgently while twirling pasta onto her fork. “Leo’s right. We love having someone new to ... share everything with. Noah’s been telling us how generous you are with him. How you let him take what he needs whenever he needs it.”
I squeezed Kiara’s thigh under the table—firm, possessive. She jolted slightly but didn’t pull away. As I am stroking Kiara’s thigh Leo stretched his leg and began to stroke my cock with his milky white with a blush of pink foot while staring right into my eyes seductively. Kiara hadn’t noticed Leo’s foot on my cock but I intentionally slide my hands higher to rub her clit lightly, because I wanted her to see how close we brothers are. Her whole body jerked as I touched it and then I whispered in her ear, “Right now I am so hard for you Kiara.” Well I am hard cause my little brother is so good with his feet. As she heard my whisper her pussy reacted with a pulse but her facial expressions remain stoic controlling her horniness in front of my family, shyness does make a person become stoic, from the outside at least. Then she also slides her hand to feel my hardness, but as she reached for my cock, she felt Leo’s soft foot stroking my cock.
Kiara then looked up with her flushed expression at Leo, who was sucking his finger with pasta cream on it and when he noticed that Kiara saw them in the act, he didn’t flinch or tries to hide it, instead he winked at her. That made Kiara choke on the food, her hand going directly to her mouth from my dick and she began coughing and my hand from stroking her pussy to stroking her back.
“Oh my, Kiara are you okay my darling?” Mom said standing up and bending over the table, arching her thin waist making her huge ass out and her boobs hanging with her huge cleavage right in front of Kiara’s face, giving her a glass of water. I rubbed Kiara’s back and after a moment she stopped, “I am sorry, I am okay now. Thanks for your concern.” She said with tears in her eyes and slowly drinking water.
But before she could settle her mind about her boyfriend being “gay” or if he’s gay for his brother only or he’s gay only for femboys or is my boyfriend really gay, she really gave up the thought about Leo being my brother the moment she saw me and mom kiss but is more concerned about being me gay, the main door slammed open with a sharp thud. Everyone’s heads turned—except Leo, who just smirked wider, slowly withdrawing his foot from my lap like he’d finished a casual stretch. It is my hot older sister, Xoe (21), coming back from her work in frustration as usual.
