Ultimatum

Time seemed to freeze as I knelt there in the living room. My mother towered over me, her appearance total insanity from head to toe: flaming eyes, a wicked grin, huge, heavy breasts, toned limbs, a fat, foot-long cock, and a pair of basketball-sized testicles pulsing with unholy power.

Behind her, my sister and the girl next door were lounging on the couch. They were locked in a sticky embrace, casually groping one another as viscous strands of Mom's jizz connected their bodies. They kissed, too, when they weren't staring at my mother's backside with lust in their half-lidded eyes.

A drop of pre-cum formed at the tip of Mom's swollen cockhead, then fell to the floor in slow-motion. As it landed on the ground with a splat, the spell was broken, and time resumed its normal flow.

"Brandon, honey," my mother began, in her characteristic half-growl half-murmur. "You might have noticed Mommy going through a few changes, lately. I hope you have, anyway."

"I... Um, I--"

"Sssh. Just listen. It's my turn to talk, now." As she continued her hand wrapped around her thick shaft, stroking slowly. "It's my turn to do a lot of things. I don't have to answer to anyone--Not you, not your father, nobody. I can finally do what I want. Live the life I want. Have the things I want."

Ella giggled at that, then reached out to guide Claire's hand from her perky breast down between her legs. I could hear the shlick, shlick, shlick as my crush began fingering my sister, her hand quickly becoming soaked with her juices and Mom's cum.

"I'll still be your mother, of course. I've just... Changed. A little. For the better." My mother was deathly still as she talked, apart from the hand moving up and down her cock. "I want different things, now. Did I ever tell you that I hated blowjobs? No, of course not--I wouldn't have talked to you about that sort of thing. I was a prude! That ship's sailed, now, so..." She chuckled. "Your father was a fiend for oral sex, dear. He'd stick his cock in my mouth every night, if I let him--And sometimes I did, just to get him off my back!"

Despite everything that was going on, hearing my mother talk about blowjobs trigged a burst of embarrassment. "Mom--"

"Hush, dear. It's my turn, remember?"

The heat behind her gaze flared up. Terrified, I nodded for her to continue.

"Speaking of 'my turn,' well... I've developed quite a taste for getting my cock sucked! I wonder if I picked that up from your father, when we became one?" She licked her lips. "That would explain the anal obsession, too--He was always after my back door, not that it ever got him anywhere. Like I said, I was a prude!"

"But we're not," Claire piped up suddenly, reaching around to cup my sister's ass.

"No, you're not," Mom replied, her grin growing wider as she looked back at the jizz-coated couple. "Not for me."

A particularly vigorous stroke sent another glob of pre-cum splattering onto the floor just in front of my knees.

"I've picked up a lot from your father... The part of him that's still inside me, anyway. Most of his... I don't know, his 'essence?' Most of it is long gone. Pumped into Ella, if I remember correctly?"

My sister nodded and purred happily, massaging her stomach.

"But now I'm full again, and I need to make room. You're going to help me with that, Brandon."

The word left my lips before I could stop it: "No."

It was barely a whisper, but it left Mom looking like she'd been slapped in the face. "'No?' You think you can say 'no' to me? You think you have a CHOICE?" She took another step forward, her hand a blur as it worked its way up and down her member. It was still growing, somehow, easily as long and thick as my arm. Her testicles bounced with every stroke, the light inside shifting and swirling.

"Well... You do have a choice, sweetheart. You can help Mommy relieve some of the pressure your little friend is putting on her poor, swollen balls... Or..." She took a deep breath. "You can join her. I'll eat you up, turn you into seed, and pump you out--Maybe you'll finally get to be inside Claire's pussy? Like you've always wanted?"

My blood ran cold as she laughed, long and loud. Ella joined her, but Claire was too busy--She leaned back and began masturbating frantically, consumed with raw arousal at the very thought of getting pumped full of Mom's jizz--Pumped full of me.

"...I'll do it," I whimpered, as soon as I was able to get the words out. "I... I'll help you."

All three of them moved at once. Mom stepped forward, bringing her bobbing erection closer and closer to my parted lips. Claire and Ella slid to the floor, scurrying across the room to kneel on either side of their... Well, their master--Mistress? I don't know. In any case, they wasted no time cradling her distended balls, covering one each with their wet lips, stroking hands, and bouncing breasts.

All three of them moaned at once, too--My mother's voice strong and loud, while the other two were muffled and meek. Not as meek as the sound that grew in my throat, of course, as Mom's bulging cockhead tapped against my mouth.

"Open wide, dear. I know you're going to have some trouble with this... But once I get started, I won't stop until you're full. Get ready."

Without waiting for a reply, she grabbed the back of my head and shoved her dick inside. It filled my mouth, stretching my cheeks--And that was before I had even taken in her entire cockhead. When she actually began to thrust, working her shaft into my tight throat, I nearly blacked out.

But I held onto consciousness for several more minutes--Long enough to feel Mom's cock twitch, then pulse, then spew an endless waterfall of jizz into my poor, unprepared body. It filled me to bursting, thick globs of seed spilling down my chin as it flowed faster than I could swallow... But only so much could squeeze out of my stretched-open lips at a time, with Mom's titanic shaft plugging the opening.

I could feel my belly swell, pushing against my shirt as the impossible deluge continued. I couldn't breathe, could hardly think, as I was turned into a worthless, degraded, inflated, half-dead cumdump.

Swallowing one final gulp of the magical jizz that used to be Beth Parry, my eyes rolled back and my mind went blank.
