Your stepmom Jeongyeon and stepsister Yuna both dealt heartbreaks in their life, and as the caring older stepbrother and son, you have to be their by their side to offer everything you can do for assistance. However, your relationship together would then take a different turn when they ask for an unimaginable favor that will change the trajectory of your family forever.

You slowly woke up with a weird sensation below your body. Glancing down, you noticed that the bedsheet formed like a hill as it shuffled, and that you can feel something is moving on your crotch.
Swaying the sheet away, you unveiled your hot stepsister Yuna doing a kickoff to start your day by giving your morningwood a blowjob. As you caught her, you shut your eyes and thrown your head back in pleasure when you felt her lips puckered around your shaft tighter. Yuna checks at your reaction, she smiled in satisfaction and continued bobbing her head.
“How long did you sneak into my room?” You asked. Your legs remained spread wide open with Yuna curled like a ball focusing on your hard cock. She jerked it off, spreading her spit and your pre-cum all over the skin first to be able to respond. “20 minutes ago.”
“You’ve been sucking me off for almost half an hour now?” You were startled, it was insane to you, her sex drive never fails to impress you.
“That’s why I love your cock so much, stepbro. You can endure for that long and still haven’t cum. Shall I edge more often?” Yuna asked while she gave your foreskin a smooch and a lick.
“Oh yeah that would be fantastic, but right now I need to cum in your mouth, stepsis.” You requested.
“Ahh that’s why you woke up.” She giggled. “Seems like I got you now. Okay, stepbro give it to me please. I want your cum for my breakfast.” She made her pumping faster before sucking you off again. You guided her motion with a hand to her head. All you can do is lay there and moan in pleasure as your stepsister takes care of your incoming orgasm.
You thrusted your hip upwards to create a strong push of your cum firing inside her mouth. Yuna contained her lips around your base, deepthroating you to make sure not a single drop gets wasted for her to taste and swallow eagerly. As your cock stopped twitching, she slowly slips off and let it collapse on your abdomen while she made you watch her empty your cum like a good girl.
“You’re so incredibly sexy, Yuna.” You huffed and rolled your eyes.
“I just can’t enough of my attractive stepbro, so be responsible for what you did to me.” Yuna squeezed your balls teasingly and you shivered, which made her smirk evil.
“Damn it, Yuna. I’m sensitive there!”
“Even more perfect, I might train it next time. Maybe I can find a strategy to make you cum fast in less than a minute.” Yuna replied. “Now dress up, I’ll go downstairs. Mom might be there now making breakfast.”
You nodded. Yuna exits your room while you rose from the bed and grabbed your shorts that she removed. After wiping off your wet cock with a tissue, you stuffed it back into your underwear and joined your family outside.
This forbidden relationship you have between with Yuna began when you comforted her after she and her boyfriend broke up. You crossed into her bedroom that night and heard her crying through the door. Excusing yourself to enter, she did allow you and there -despite not blood-related- you checked up on her and listened to every words she wanted to get out from her broken heart.
You cuddled her to ease her tears away and it became effective. However, that only intention you were trying to do prompted something more on Yuna that made her do what she’s been battling against after she accidentally caught you on a shower taking a bath.
She looked up at you with her watery eyes and stared at your face for a second before she reached out for a kiss. Stunned and internally panicking that your stepsibling just did that, you separated her away and asked her why she did it.
Yuna confessed that she has been finding you captivating ever since that accident. She tried to fight back to her feelings because even her knows and believes it is a taboo to become attracted to a family member, specifically to a sibling. But in this moment, with how affectionate he’s being at, Yuna got all those struggles and she has now exceeded her breaking point.
She didn’t care anymore, she wanted to forget what her ex did to her. Only you who she always wanted for a man could make her feel better, disposing every fear of stepping into the boundary. Both of you ain’t blood-related anyway, so she corrupted her mind with a new belief that this is just as right, for the sake of her emotional stability and contentfulness in life.
You also expressed worry about the possibilities that your mom might find out about this. Yuna assured you that she’ll do it carefully. Admitting that she looks beautiful and somehow tempting that you can’t refuse a type of woman like her, you succumb to the temptation.
Both of you stripped out of your clothes and had few rounds of sex on her bed. Never thought from one of you that someday in this very room, both of you would be there laying alternate while stacked at one another, eating each other out. Not even fucking yourselves like wild animals, taking her to every area of this four sided secluded room doing a sin that nobody should discover.
That’s how your newfound connection with Yuna as fuckbuddies began. Until now, you two find ways to pleasure one another when your mom doesn’t have her eyes on you both of if her presence is completely absent. However, Yuna sometimes put you both in near danger just like today when she was rubbing her soles on your bulge under the table while you three are eating breakfast.
Later that night, she sneaked out again of her room to join you in the bed and make out. Without wasting more time, you pounded her on all fours at the wall. As usual, her ass was your main target due to how large and perfectly proportional it is to her wide hips.
Not all secrets can be kept hidden though. Oblivious to you both, someone was listening to her moans and the clapping of each others skin. When you finished cumming on her ass, she went to the bathroom to clean herself up.
The next morning, Yuna went out to meet some friends. That leaves you alone with your stepmom, Jeongyeon. You were taking a shower when suddenly you heard the door open, instinctively covering yourself up in shock.
Jeongyeon stood there, all serious as she stared at you. She hanged her towel at the door and proceeded to remove her clothes. For the first time in your teenager life, you saw you mother only in her bra and panties.
“Mom, what are you doing here?! Can’t you wait for a little longer, I’m almost finished!” You complained, while your eyes couldn’t leave her body. She looks so thick, even though Yuna isn’t her biological daughter too, she also sports wide hips and meaty thighs. Even her ass looks huge, made you thinking that it was not a coincidence that they were paired up as mother and daughter someday in life.
“Oh, so I can’t enter here and share a space with you being naked.” She said. “But you’ll allow your stepsister instead to wash you if she’s the one who popped up here than me.” Jeongyeon glared at your expression lifted up into astonishment and fear.
She unclipped her bra and hanged it there with the towel. Her hands moved away from covering her tits and bent down to proceed with her panties. You stared at her deep cleavage and their full size as she straightened her posture again.
Snapping back from suddenly lusting at your stepmom’s body, you are so doomed knowing exactly what she’s pointing out. “M-mom, I can explain. S-she was heartbroken that time a-and I just went there to be a caring brother to her. B-but she initiated all this and I-I couldn’t stop her…”
“Because you wanted it too, a body couldn’t lie at how it reacts.” Jeongyeon slowly walked to approach you and join you in the shower. You were about to retort and defend yourself but Jeongyeon interrupted you. “Shush with your reasons, I don’t care about it. There’s only one thing I want you to do for me if you want me to forgive you and continue screwing your sister.”
You remained silent, completely confused that Jeongyeon doesn’t have any problem at all when all the time you are scared she might caught you two red handed and get kicked out of the house. “Now that I heard it from you directly, I hate it more that it’s so… unfair to my part. Is she the only one needed to be accompanied with what she desires to a guy? How about me? I’ve been a widow for years now since your father passed away."
You listened and watched Jeongyeon expressing her despair. “I miss him so much, including his touch. But now he’s gone, I couldn’t have a man’s touch anymore that makes me feel good like what he does. Then I found you and what your sister were doing… I thought maybe there’s still a way for me to aid all this longing I’ve been having.”
She placed her hands on your chest and leaned herself closer at you. “You are the only man that resembles similarity to your father, YN. You won’t mind also putting your attention on me, right? You can have your sister all you want, just… don’t make me feel forgotten and alone. I want you.”
She kissed you on the lips, you stayed there as you were processing what is happening right now. Your mom disposes every what ifs you’ve been having of this affair you have with Yuna by also secretly wanting the same affection as her. It’s hard to deny that even at her age she still looks stunning and hot in her own style, which is hard for you to decline her request.
Not minding about the taboo anymore, you accepted her intimacy and kissed her deeply while groping her ass. She pushed herself closer to you, her tits were now squished at your chest. As she felt your cock rising up getting turned on at this moment, she quickly grabbed it and stared at you now with lust and hunger.
“Here's my answer. Now let me accept it gratefully.” She kneeled at the tiles and looked up at you, her face being sprinkled by water on the same level as your hard cock was a surreal sight. “Can mommy suck your cock, darling?”
“Yes, please.” She felt the weight of your warm meat on her face first, sniffing and rubbing it all over. Slapping your cock on her tongue, she slowly takes you into her mouth. You let out a large sigh as Jeongyeon performs her first ever blowjob at you.
Compared to Yuna, she was less sloppy and it is clearly indicated she was a pro to this. She knows how to glide her tongue to every inch of your shaft, not even your mushroom head and foreskin being left out from her lewd oral service. A deepthroat was a no hesitation for her, she easily buries her face down on your crotch and swallow you all down on her tight throat.
“Fuck my face, baby.” You complied. Grabbing Jeongyeon’s head, you buckled your hips and began to move back and forth to dagger into her mouth. No gargling sounds can be heard, she welcomes your cock like it was perfectly fitted for her. You watched your stepmom looking above you as you hump on her face while she clutches on your thighs.
You groaned as you cum intensely on her mouth, going straight in her throat as she gulped them all down properly to fill her tummy. As she lets go, she washed your cock to remove all stains of cum and her spit on it. Standing back up, she offered you one of her leg. “Take me like this, baby. I want to see how you go deep inside me.”
You handled her kneepit and she helped you point your cock in her awaiting pussy. Pushing forward, Jeongyeon lets out an ahh and screamed at how big you are inside her. She’ll have to be more adapted on your size as the shape of her late husband is still within her, that way probably her longing could finally vanish.
You continued to thrust and send euphoria to Jeongyeon’s senses. She reached for your cheek and stares at you lustfully as you fuck her on the wall one-legged. “Oh my God, you’re just as great as your father, baby. Fuck! Maybe even better, you’re splitting me in half with that monster!” She yelled as she indulge how your manhood drives into her pussy.
“Mom, you’re so tight! I can see how much you’ve endured not getting any of this.” You said. Your balls slap into her clit the more you go deep into her. Jeongyeon can now feel your skin clapping into her center as well, she doesn’t have any plans to hide how much she’s loving this. “I’m so glad I never invested to any rubber toys to stuff into my pussy when I can have you for myself, you can easily beat them with how perfect your cock is to me, baby.” Jeongyeon complimented.
Your grip to her thighs became stronger. She was pressed further on the walls as you keep finding more angle to rub every inch of your length in her inner walls. Jeongyeon keeps on moaning as she can feel how she is being spreaded wide by your massive girth.
“I’m about to cum, mom. Should I do it inside?”
“Yes, please fill me up. I want to feel all of you inside me!”
Few more strong thrusts and Jeongyeon yelped at how much the amount of your cum were unleashed into her birth canal. She won’t be shocked if she’ll get pregnant at how much you poured right in front of her womb entrance. As you released yourself from her, you help Jeongyeon steady her stance and both of you kissed as she’s still trapped on the wall around your body.
“Let’s wash ourselves up, shall we?”
“I would love to.”
After helping yourselves bathe rubbing every sections of your bodies, you joined Jeongyeon out of the bathroom. Yuna came home an hour later, and what she discovered made her halt in astonishment. “Uhh, what the heck?”
