Momma Asserts herself as the Alpha

Before you could stop yourself, you begin to whine, "What?? No! But I didn't do anything!.."

Your mother intensely glares back at you for your outburst, forcing you to avert your eyes to the floor. She says tersely "I don't want to hear backtalk like that young man. Keep talking and you'll get a real punishment".

She continues "And you're correct that you didn't do anything wrong, it's not a punishment. However Mommy needs to assert dominance over your sisters tonight so it wouldn't look good to have your little cock freely getting hard and shooting your little loads whenever you like. Now, clothes off mister!"

You hurry to undress until you're completely naked except for your pink collar and buttplug still lodged in your ass. She then gives her next instruction again, "Hands behind your back and thrust that little cock forwards."

You do as she commands and soon enough, she fits your dreaded pink cage onto your penis, making a snug fit around your cock and balls, ensuring you wouldn't be able to get hard tonight. Your mother moans in excitement as she looks you over, "Mmmmm".

She then undresses in front of you and puts on her own pair of white lacy lingerie, starting with white stockings that ended halfway up her thighs. She turns around to show you the rest and you can see her soft dangling cock and balls are completely sticking out the front of her getup. She has on a bra and garter belt but no panties. You look closer though and realize that wasn't entirely true. The bottom of her garter belt had two thin straps extending down to her crotch. You followed the straps with your eyes and noticed your mother had on some kind of white lacy bra for her big full balls. You almost missed it because her sizable cock had been dangling over the futa-exclusive lingerie.

Your mother says to you "Baby, if you keep staring like that you're going to excite Mama's big willy and we won't be able to wait for your sisters anymore."

You shake your head and avert your eyes in embarrassment, your cheeks probably reddening from staring at your mother's cock and her catching you.

Jennifer, for her part, just smiles and then pulls the leash from earlier out of her purse, attaching it to your collar and holding the other end firmly in her hand.

At that moment, you hear a knock on the bedroom door and your mother says loudly, "We're ready! You girls can come on in!"

Your sisters file in the room, Jessica following behind Zoe. They see the pair of you standing next to the bed in your kinky attire and Jessica whistles, "Damn, lookin' good Ma." She looks at you and grins, adding "You too slut."

Your mother says "That's enough of that Jessica. From now on, I want you to make an effort to be nicer to your brother, at least while you're given my permission to use him in my place." Jessica just responds with a dismissive "Pshh.."

Your mother then says to your sisters "Now why don't you girls take your tops off and give your brother a nice show."

Jessica looks down at your caged cock and says "Why? It's not like it's gonna do him any good."

Your mother responds strictly "Jessica! Don't make me tell you again young lady! You are not in control in this room and if you're smart, you'll do what your told like a good girl."

She looks at your sisters with a serious glare and continues, "You both need to understand something right now. While you're in this room, Mommy is the alpha and you two are my good little betas. What I say goes or else you're cut off from your little brother. And if you want to keep using MY cocksleeve, you'll continue being good betas while you're living in this house. Is that understood girls??"

Zoe immediately answers "Yes Mom, we understand..", while Jessica seems to struggle with her response, mumbling something in return.

Your mother says to her "What was that Jessica?"

Jessica answers in a whiny and bitchy tone "Momm! Do we really have to do this?? This is so fucking humiliating."

As your mother responds with a defiant yes, Jessica continues "When this gets out, my life is going to be over! I'm gonna be the laughing stock of all my friends!"

Your mother says to her "No you won't sweetie, don't be so dramatic. I'm told by other parents this is quite a common arrangement. Besides, this is our own personal family business, nobody is going to find out."

Jessica squarely points at you and loudly says "You think I'm gonna believe THIS little weasel isn't gonna blab about this?!"

The words just come out as you respond to her accusation, "What the hell! Why would I?? So I can tell everyone how Mom shares me with my horny sisters??"

Your mother then places a firm hand on your shoulder and says to you, "Babyyy I don't want to hear anymore outbursts from you while you're on Mommy's leash. Do that again and I'll pull you into my lap and spank your little cock and balls in front of your sisters."

You gulp as your mother says to Jessica "But you're brother's right honey. He won't tell anyone, he's a good boy who listens to his betters, his mother especially. Isn't that right sweetie?"

You nod your head in an affirmative and Jennifer says "See. Are you satisfied now?"

Jessica answers "Ughh, fine whatever, I'll follow your stupid rules. Let's just get this over with!", throwing her hands up in surrender as she talks.

Jessica aggressively pulls her top off in a fit of annoyance, leaving her in just her bulging panties. You look at her body and nearly gasp in excitement as you see her perfect perky large breasts in full view only a couple feet in front of you.

A second later and Zoe follows her sister by removing her top, exposing her even larger bust. They weren't as round and perfect as Jessica's and were more of a teardrop or bell shape, but they were clearly much larger and drooping down her somewhat chubby body and stomach.

You already knew Zoe had uniquely big boobs just from the way they're always straining against her shirts and bras, but seeing them naked in front of you gave you a new appreciation for Zoe's voluptuous chubby form. Her slightly chubby belly curved outward above the waistline of her pajama bottoms and curved into her bottom-heavy love handles. She definitely had fat in all the right places. You look between her and Jessica's young playboy model body and suddenly your cock begins to strain hard against your pink cage.

You're cock is throbbing in its cage so bad you instinctively reach down to grab it with both hands with a pained look on your face. Jessica sees you suffer in the tiny chastity and gives an evil excited grin. She says "Nevermind I take it back, maybe that was a good idea."

Jennifer then sits down on the edge of her king-size bed, legs spread apart so her dangling cock is on full view. She says to your sisters, "Okay, now I want you girls to take Marcus's plug out and get his little hole ready for a nice pounding." She looks at you and says commandingly "Turn around and bend over for your sisters sweetie."

You do as she says and bend over a little while arching your back. Now feeling exposed and **** to your sisters, you hear Jessica say "Don't worry, it'll be my pleasure to do the honors."

You feel a hand firmly grasp onto the base of the plug in your ass, and you gulp in a bit of fear. Your mother blurts out "Remember Jessica, be nice to your brother", and your anxiety fizzles just a little bit. It was strange feeling like your mother was there to protect you and was a comforting warm presence again after everything she had done to make you her personal cocksleeve. It definitely helped you had recently begun enjoying being her exclusive boy toy and fleshlight sometimes, but getting shared with your sisters, especially Jessica, made you incredibly uneasy.

You then feel one of Jessica's smooth perfect boobs press against your back as she leans forward to whisper in your ear. She seductively says to you, quiet enough so only you could hear, "Mmnn, I can't wait to make this slutty little bitch hole my personal cum receptacle."

She begins to twist and pull the plug out of your ass, only to just slightly pump it back in to grind against your prostate, illiciting a moan from you. Before anyone can say anything, she then finishes pulling it out. As the tip exits your hole with a squelching feeling, Jessica whispers again, "Just so you know, you're gonna be my mindless cock addicted puppy dog once I get through with you."

She then steps back with the plug in hand, acting as if nothing just happened. Jessica was being predictably shady and scary toward you when nobody was listening, but you also had to admit her words also struck some hidden excitement in you, leading to your cock to strain in its cage again whether you liked it or not. You still didn't trust her one bit though and could only hope your mother watched her like a hawk.

You look over to Zoe to see her looking around the room for something. She speaks up "Uhh Mom, where is your lube at?"

Your mother answers her "Oh honey, you two won't need lube, you'll be getting your brother ready with your mouths."

Jessica makes a disgusted face and says "Eww. There's no way I'm doing that."

Your mother says "Yes you will little lady. The sooner you accept our arrangement, the faster we can move this along, otherwise you can leave right now."

Jessica doesn't answer, decidely not pushing your mother's patience. She clearly had plans for you after all and didn't want to blow it, but still, she made no move to step forward.

Zoe, on the other hand, quickly accepted her task and gets on her knees, placing both her hands on your ass to spread your cheeks.

She leans forward and gives your hole an experimental lick, sending shivers up your body. Zoe says "Wow Marcus, you have a really cute butt." She leans forward to lick you again but stops right in front of it, saying "And your tight boy pussy looks so yummy." She begins lapping at your hole, covering it in her saliva.

Jessica leans down and quietly says "Lemme see...", trying to get a better look as her panties begin stretching at the crotch.

As Zoe inserts her tongue into your ass, you gasp and your panting soon becomes quiet moans. Behind Zoe, Jessica gets down on her knees herself to better watch the show but still defiantly makes no move to help her sister.

A few minutes later and Zoe is outright tongue fucking you. She seemed to be more than willing to eat your ass, and you were sure she had to be pitching a huge tent in her pajama pants right about now from the way she was licking your ass with gusto.

You look up from the floor and see your mother stroking her big hardening cock as she watched her daughter lube up her cocksleeve son with her mouth. Your mother was also clearly getting off on exercising her power over you and your sisters. Her face was flushed with lust, and she looked like she was ready to pounce on you.

Your mother says to Zoe "Alright, that's really good sweetie, but take a break and let your sister have a turn."

Jessica says "Fuck No Mom. I wasn't joking before, there's no way I'm doing that with Marcus."

Your mother locks eyes with Jessica and says "Honey, there's no way your getting out of this without licking your brother just a bit."

Jessica groans in frustration "Ughhh, this is so unfair! Beth doesn't have to deal with any of this shit and she fucks her brother all the time!"

Your mother answers "Well maybe you should go live with Beth then, I'm sure she'd be so happy to share her brother with you."

Jessica groans again that almost turned into a scream, and she suddenly pushes past her sister and lodges her mouth between your cheeks to give you two quick licks on your asshole before pulling back. She says annoyed, "There! Happy??"

Your mother says "Give your a brother a kiss on his cute little tushie and I'll consider it a passing grade."

This time your sister does squeal in annoyance and says "Really Mom??"

At this moment, you couldn't help yourself and subconciously begin taunting your sister. She was finally seeing at least some punishment for her bitchy behavior and it was making you instinctively grin at her groaning and screaming. You start shaking your butt from side to side, taunting her to kiss your ass.

Your sister sees this and growls at you. This only makes you smile more and you quietly say to her "C'mon Jessica, just give it a little kiss"

You clearly weren't as quiet as you thought though and your moment of retaliation quickly backfires. You hear your mother yell at you "Marcus! Stop that right this second and apologize to your sister!"

You say a half-hearted sorry to Jessica, which then ends up with her grinning instead of you.

Your mother continues tersely "Do that again and I'll let your sister spank you over her knee for as long as she sees fit." You gulp at the thought of Jessica having free reign to spank you.

Your mother says "For now, come over here and I'll let you off with 5 quick spanks so we can hurry this along."

You answer "Yes Mommy...", as you then step toward your mother. She grabs you around your waist and bends you over in front of her, spanking you on the ass with her right hand.

As she spanks you, she casually continues talking "It's no wonder you two can't get along when you tease your sister like that. I thought I raised you better than that Marcus."

She doesn't hold back as she open-palm smacks your bare ass in quick succession 5 times, making your ass pink just from that alone.

Your mother then turns your ass back towards your sister and says "Sorry honey, go ahead and finish up."

Jessica just looks toward you both with an evil grin and says "Thanks Mom, I think that'll help a little to teach him to not be a brat. I heard that daily spankings are effective in preventing that behavior altogether though."

Your sister leans in, gripping her hand around your upper thigh as she places a kiss on your pink buttcheek. As her lips touch, she squeezes her hand so her finger nails dig into your thigh.

You let out a little scream "Ow!", as your sister's hand then loosens and she backs back up, still holding that same grin on her face, basically telling you to know your place.

Apparently if your sister was going to be put in an uncomfortable position, she was going to deal with it by making your life worse and venting her frustration on you. It was classic Jessica bitchiness and you really should've expected this.

Your mother says "Stop whining baby, you've dilly dallied long enough. It's time to sit on Mama's lap.
