Make dad your bitch

When you're mom is don't cleaning your cock, you and Robin break from making out. You sit the girls down and explain to them how you're going to carry out the plan. Everyone plays nice for now, but tonight at bedtime it's on.

Throughout the family dinner the three of you exchange smiles at your secret. You look at your father and almost pity him for what you're about to do, but then remember how distant he's always been, and on top of that he pushed your mother to find loving elsewhere. No. He deserves what's coming.

After dinner you all go get ready for bed. You and Robin in your room clean up and then you wear just boxers while you make Robin wear her lacy black bra and thong. You sit on the bed and wait for Mom to do her job.

Right on time, your mom opens the door and walks in to your room wearing a sexy red teddy. She didn't bring anything for her husband and only the plug for you at the last minute, so Robin loaned her something slutty. Your mom's bigger tits spill out the top, and the length does nothing to hide any more than her bare ass in a matching red thong.

Your dad is wearing just at shirt and pants for bed. He's confused and starts to avert his eyes from his daughter dressed to fuck and he objects. "Heather what the hell are we doing in here? We shouldn't..."

You raise your hand and cut him off "bup bup bup... Enough."

"You can't fucking talk to me like that!" He replies. Robin is smiling wickedly watching it unfold just like you planned.

"Mom, bend over," you order. She does just that, ass facing her husband.

"Don't you fucking talk like that to your mother either you little shit! Heather what the fuck are you doing? Don't do what he says!" Your mom ignores him and obeys you, following the plan and spreading her ass.

"See, dad, what mom is showing you is her butt plug. 'Mommy Slut'. You know why her butt plug says that? Because she's my slut. When you ignored her, I took care of her needs in ways you never could."

Your father has a look of horror in his face, the color draining. "Oh, no..."

"Oh yes, little cucky. And I do mean little," you say before cup checking him roughly and making him collapse a bit. "I cuckolded you. Not while you were on a break this time. Today. I wrecked your hot wife in all three of her hot little holes. So not only is she my slut, but you are now my bitch." You push him back into a chair in the corner. You were prepared to order him or need to **** him, but he's so stunned he is literally a pushover now. "You're going to pay for how you didn't give Mom what she needs, and the first step of that is going to be tonight when you have to watch. You have to watch me not only fuck your sexy daughter, but watch us use your sexy wife as our fuck toy."

You motion to Robin and she lifts your mom from her bent over position. Robin kisses your mom hard, tongues dancing. Then Robin guides her head down so your mom kisses down to the edge of Robin's bra. Robin whispers "take it off" and your mother does as she's told. The bra falls to the floor and your mom begins to devour Robin's perky teen tits.

You whisper in your dad's ear. "I know you've been checking out my girlfriend, wondering if she's as sexy naked as she is clothed. The answer is yes, and then some. But what you never thought to ask was just how dirty your wife was. You never even scratched the surface. Look at her, if you think she looks hungry sucking on Robin's tits, you should have seen her eating my cum out of Robin's pussy earlier, you limp dick loser. Now stay here and enjoy the show, and see just how much you missed out on all because you didn't give your wife attention. Watch and see what a real man can do with her."

You leave your dad to wallow in the corner and join the girls. Your mom is bent slightly to lower her head for sucking on Robin's tits. You give her ass a good spank. Your mom moans and shakes her ass again. Robin smiles at you, "yeah baby, spank your little slut's hot ass!". You do just that, admiring her fine butt before you make your next move.

"Robin, get on the bed. Spread those sexy legs. Mom, get in there and eat your daughter's hot pussy." You watch as your ladies do their master's bidding. Robin grabs your mom's hair and presses, already morning as soon as she feels your mother's tongue lapping at her sex. Your mom raises her ass high, pointed right at you. You look over your shoulder and give a devious glance to your father before you seal the deal.

You kneel between your mother's legs and give her another slap. You pull her panties down and squeeze her naked cheeks. "I want to hear you beg for it, mommy slut" you tell her.

Robin lifts your mother's face and let's her speak. "Please master, fuck your little slut. Use all my holes for your pleasure," she says in her sexiest voice.

"Good slut," Robin compliments her before pushing her back down to keep licking. You reveal your hard cock, Robin licking her lips admiring it. You imagine your father is a mix of impressed and horrified, but you put him out of your mind. This is now about you and your ladies.

You run your cock head up and down your mom's soaked slit. She moans, reaching her hands down between her legs, spreading her pussy lips farther for you. You grab her hips and give her a steady deep thrust, instantly filling her. She cries out, the sound muffled by her face buried in Robin's young pussy.

You set your pace, pounding steadily away at your mom's hot cunt. "Fuck, your pussy feels so good, mommy slut." You spank her hard for good measure as you continue your onslaught. Your mom is pushing back against you, trying to drive you deep inside her with each thrust while still working on Robin's pussy. Robin is moaning louder and louder, one hand starting to play with her tits, pinching her hard nipple.

"You look like you're getting close Robin... are you going to cum before mom cums on my cock?" Hearing this, your mom moans into Robin and works faster on her daughter.

Robin moans even louder now that your mom is speeding up. "Fuck! I just might. Your little slut really knows how to use her tongue!"

"Mmm, don't I know it." You spank your mom again. "If you make Robin cum before you do, there's a special reward for you." One again you can tell that your mom is upping her game. You look to Robin. "But if you last longer, you get rewarded." Robin looks determined, but then her eyes go wide You see one of mom's arms moving forward. That little slut is fingering her own daughter to try to win. You love watching the two of them compete.

It's close, your mom is getting stretched on your big cock pounding her, but Robin is getting subjected to both the fingers penetrating her and her mom's tongue hungrily working. You aren't even sure if you care who wins, both options are going to serve your plans well.
