It was Saturday, and I had to face the displeasure of waking up alone. It had not even been a week, but I had already gotten accustomed to being woken up by Cassandra's wet kisses and ensnaring limbs.
Unfortunately, she had to leave early for some kind of weekend exam at the university. That meant I had a day to myself, at least, so I went down and made myself breakfast in the quiet of my home, able to enjoy it without any fuss or mess.
Mom came down not long after. She seemed uncharacteristically sober, wearing a long satin morning robe tied low enough to show off her cleavage. She wore her blonde hair up in a golden bun. It seemed to have regained some of its usual luster.
She ran her hand along my chest and shoulder as she passed me to open the fridge. I could hear the sounds of her padding barefoot behind me.
"Cassie's out?" she asked.
"Yup," I said. "Exam or something. She said she won't be back until four, at the earliest."
"Good."
I frowned, putting down my coffee. "What?"
Mom giggled. "Nothing."
I frowned even more deeply and turned around to look at her, arm swung over the backrest. She had her back turned to me, bent over the counter with her ass stuck out in my direction. The robe covered her posterior amply, but the silky soft fabric did nothing to hide her jaw-dropping curves.
"Mom, did you just giggle?" I said. "Is anything wrong? Should I be worried?"
"Oh, nothing's wrong," she assured me in a sing-song tone. "I just feel good today, that's all." She stretched with her arms high, and even though she had her back turned to me I could still see her tits jutting out the sides of her torso.
Okay, this is weird, I thought. Mom hasn't acted this way since she accidentally smoked some of Cass's pot. She didn't smell of weed, however, and she didn't have that kind of bleary, unfocused expression. She just looked... happy. Mischievous, somehow.
I shrugged. Mom was a mystery, even to me. I turned around to finish off my breakfast. Conspiracy theories about my mother could wait. I had a whole day of privacy ahead of me, and I wasn't about to waste it.
I felt a pair of hands on my shoulders and something very soft kneading against the back of my head. Could it really be...?
"God's sake, you really are clueless," Mom said. "You work all day to make Mommy happy, but you've never thought about what she really needs."
I swallowed hard, fighting not to look back. "And what is that?"
She leaned in and whispered in my ear. "You, Kiddo."
She spun the chair around so that we faced each other. She had opened her robe, letting her unequaled chest spill out. Each breast was big as a watermelon, firm and jiggly at the same time. Fat, dark nipples rested at the apex of each, hardening at being exposed to the air.
"Mom, this..."
"Is wrong?" she completed. "I know. That's what makes it so exciting." She started rubbing my crotch, cock filling up my pant leg as it stood to attention.
"Mom, I can't do this," I said urgently. "I... I'm with someone else."
"With sweet little Cassie?" Mom smiled wryly. "Oh, I know all about that."
This time, it wasn't just my dick that went stiff. My body became paralyzed as I watched Mom squirming like a needy whore in front of me.
"W-what? I don't know what you mean."
"Oh, come now. You don't need to pretend with Mommy. I know you two rascals have been sneaking off to bump uglies with each other. It's adorable, actually. You never were good at keeping secrets from me, though. I've known since the first day. I enjoyed seeing what she did to you in that movie theater. So much so I can't help but want to recreate it."
She got down on her knees, long nails scratching against the fabric as she undid my pants. My penis came free, bobbing up and down with my balls resting heavily underneath. Mom went all wide-eyed, reverently running her fingers along my fat girth.
"It's even bigger than your father's," she breathed. She had begun panting heavily like a bitch in heat. "I never knew you had a monster like this hidden away. If I did, I would have done this a lot sooner."
Mom opened her jaw wide and leaned in to suck my cock dry, but I took her head firmly between both my hands and tilted it up.
"Mom, we can't do this," I said. "Think about Cassandra. This would ruin her."
She bit her lip. "Yeah, and what about your poor Mommy? She gets to have you all to herself, and I'm supposed to be satisfied with nothing? I'll make sure Cassandra understands, don't worry. Just relax and let me have this, Sweetie."
I swore under my breath. This was wrong. Not just because this was my own mother, but because of what it would do to Cassandra. And yet, those big, puffy lips and that wet little tongue were calling out to me. What harm could it possibly do, after all? As long as I kept it in the family, Cassandra had no reason to complain. And this might help Mom get over Dad, as well.
As Mom stroked my cock, my crotch overpowered my brain bit by bit. Eventually, I could no longer see a reason to resist. I let go of Mom's head, and she gave me a gleeful smile before descending on my dick.
I could tell that she was far more experienced at blowjobs than Cassandra could ever hope to be. She slid even my hole-wrecker of a penis easily down her throat, taking it almost all the way down to the hilt with only some mild gagging. She maintained eye contact the whole time. She had the same ravenous hunger as my sister. A family trait, it seemed.
I could not bring myself to push her away. I had to admit, it felt marvelous. She was completely different from Cassandra in her technique. My sister was fierce, gluttonous and feisty. She would shove herself onto my cock as if it was the last thing she'd ever do, and tease me every so often.
Mom was the opposite. She was composed and experienced, calmly servicing my dick with her enhanced, fuckable cock-pillows for lips while also fondling my heavy balls in one of her dainty hands. I wondered idly how many men she'd had before Dad. Maybe her success in the modeling industry hadn't all been down to her beauty-or at least, not in the traditional application of it.
"Mm, that's it," I groaned as she went particularly deep. "God, you're such a slut."
She popped off my cock for a second, licking her lips and grinning like a cat about to corner a rat. "That easy to tell, huh? I'll admit, I've been a little starved ever since your father left. Lucky he left behind a replacement to keep me satiated."
"This is just a one-time thing."
Mom gave me a knowing look. "If you say so, Kiddo." She dove right back onto my manhood and showed me some tricks involving her tongue I didn't even think possible. It squirmed around my head with incredible nimbleness, and it didn't take long before I came close to climaxing.
I took hold of her head and thrust myself deep inside until her nose hit against the base of my crotch. She gagged weakly, eyes tearing up, but I didn't want to let up just yet.
Just as I climaxed down my mother's throat, cum dribbling down her chin, the door came open.
"Hi!" Cassandra chirped as she walked in. "Turns out I had the dates all switched around. The exam's next Saturday, not..."
She stopped dead as she walked past the kitchen and saw Mom with my dick in her mouth. She didn't seem overly concerned herself, popping my member out of her mouth and standing with a dignified stretch, letting her hands roam over her supple body. She finished by licking her wet lips, swallowing a final few globs of my sperm.
"Mom, why..." Cassandra mumbled. "What the fuck is going on?"
Mom walked up to Cassandra. "My darling daughter, come here." She closed my sister in a tight hug, ending it with a wet kiss on the mouth. "I know you must be confused, but stay calm."
Of course, Cassandra did anything but. She raged and kicked and screamed. Mom held her firmly, whispering in her ear and stroking her hair. I didn't know what to do, so I just watched while I made myself decent. I should have been ashamed, I suppose, at being found out, but I mostly just felt a... strange curiosity.
Cassandra kept up her tantrum for a good few minutes, but eventually, even she ran out of energy. She and Mom collapsed together on the couch, the latter continuing to kiss and feel up my sister's body.
"There, there, Darling," Mom cooed. "We have a new man in the house. It's only fair we both do our best to make him feel at home."
Cassandra looked up at me, biting her lip. "Would... this make you happy?"
I hesitated for a second, then nodded. "Yes. It would."
She put on a stiff upper lip. "Fuck, okay. I'll stay. Even if she's gotta be with us too."
==========
As it turns out, juggling a relationship with your mom and your sister at the same time isn't exactly problem-free. Who would've thought?
I spent my nights with Cassandra, just as I had before. She slept in my bed every night, nestled up to me like a dog. I'm sure Mom would have liked to share that space as well, but Cassandra wouldn't even let her near my bed without going off. While my sister accepted the situation to some degree, she sure as hell wasn't enjoying it.
It was a Sunday. I woke up with Cassandra, and we both got downstairs to find that Mom was already making breakfast-bacon, eggs, and toast. She wore only a skimpy apron, which not only showed off her perfectly round ass and shaven pussy, but also a good bit of side boob. Her snatch was wet, glistening drops trailing down the inside of her leg.
Cassandra turned away in disgust and plopped down at the table, crossing her arms and putting her feet up on the table as she pouted. I stroked her hair gently and whispered a few calming words before walking up to Mom.
