Duffs Dairy

Duff's Dairy

"Thanks again for taking the kids to Disneyland and giving me a day to myself, sweetheart." Hilary Duff cheerily kissed her husband Matthew goodbye while handing him the overstuffed diaper bag. Luca, Banks and Mae were already in their seatbelts, with an empty car seat waiting for its precious cargo, 8-month-old Towne.

"Honestly, I don't think you gave me much of a choice" Matthew muttered while struggling to get the squirming infant securely in place. "You could have at least let one of the nanny's come to help out. I'm not looking forward to it."

"You'll be fine" offered the bubbly actress. "I put lots of diapers and extra formula in there along with snacks for everyone. I really do appreciate it, honey." Fluttering her brown eyes at him, the 37-year-old celebrity drew him in close and over his jeans, cupped his penis in her hand. "Promise I'll make it up to you later" she whispered, knowing full well that she wouldn't. They kissed once more, then she stood waving from the front doors to her mansion, anxious to check her text messages.

There were three, all from her sister Haylie. Each one asked the same question. "Did they leave yet?" Hilary replied that they'd just gone, and that her older sibling could come over at any time.

The former child star walked into her kitchen and started the process of making a pitcher of fruit smoothies. Each of the nannies had been given the day off so she and Haylie would be alone for the next several hours. Reacting to her phones' notification ping, the pretty blonde read that her sister was only 10 minutes away, and that she should be ready. Placing the strawberries, blueberries and soy milk back in the fridge, Hilary climbed the staircase up to her bedroom to do just that.

Haylie had the code for their security system, but Hilary knew she'd want to be greeted at the door. After stripping herself of all clothing and jewelry (including her wedding and engagement rings), the shapely blonde twisted her locks up into a messy ponytail and applied a quick spritz of "Born Dreamer" between her swollen, new mom breasts. Her petite, bare feet swiftly carried her down the winding staircase which spilled into the tiled, front foyer, just as the doorbell announced her sibling's arrival.

Beaming with happiness, Hilary opened the massive door and presented her naked body to her grinning, older sister. "Come on in, beautiful. It's been too long. I feel like I'm going to explode." Haylie was wearing tight denim jeans and a vintage Lizzie McGuire tee shirt that seemed as if it had been painted over her ample, 34B breasts. She strode over the threshold confidently, and immediately scooped her sister up in her arms. They were the same height at 5'2", so breasts and pussies crushed together as Haylie probed the depths of her sisters' sloppy mouth with her tongue.

While firmly squeezing the 37-year-olds plump, meaty ass, Hailie leaned back slightly to better admire her sisters' engorged tits. Their nipples were darker and larger than normal, and blue veins could be seen just underneath the pale, creamy skin. The brown-haired actress felt a tickle in her already wet cunt dance its way up into her belly. "Let's go up to the nursery" she whispered. It wasn't a request.

Hilary led the way up the staircase so that Haylie could watch her ass sway while occasionally giving a peek at her moist, pink lips nestled underneath. Her sister had been here many times before, though not as many as she would have liked. "Hope you're enjoying the view" the cute blonde teased, casting a quick glance back as she reached the top.

The nursery was located at the end of a long hallway, right across from the primary bedroom. Once inside, Hilary went about retrieving the "toys" they'd be using, while Haylie undressed. Now also naked, the eldest Duff took a large, strap-on dildo out of her tote and stepped into it. It was 12" long and as big around as her closed fist. It was also a new addition to her arsenal, and this would be Hilary's first time experiencing it. "C'mon, Hils. Let's get this party started."

The curvy 37-year-old returned just then, sat down the storage case and positioned herself on all fours at the foot of the crib. Having done this many times before, Haylie took out two pair of handcuffs from the case and fastened Hilary's wrists to her ankles, so that her rounded ass was up in the air and overfilled breasts hung underneath like udders. "Matthew doesn't understand why my breasts are still full of milk since we've been feeding Towne formula this entire time" offered the Lizie McGuire star while her sister started the breast pump and began fastening the suction cups to the singers' enlarged nipples.

"Yeah? And did you tell him it's because your sister has been milking you like a cow and selling the milk on the dark web?" Haylie laughed. The machine was the best and most forceful available for private use, and immediately began pulling on the bound blondes' quivering chest meat, drawing out dribbles of the liquid nourishment along plastic tubes and into sealed bottles. "You wouldn't believe how much fans are willing to pay for fluid that came out of your body. But you know what makes the milk taste sweeter, don't you, Hils?"

"Ooh, yes" cooed the helpless, former child star. While her replete, ivory tits were being emptied by the humming pump, Hylie walked on her knees behind her naked sister, slathering the giant, silicone penis she wore with lube. Hilary's fuck hole was already dripping wet, it's pink lips open and glistening with her girl juice, but that wasn't where Haylie was aiming. "Ngh" grunted the 37-year-old as the large, plastic head pushed against her resisting rear entrance. Even though her sibling had fucked her ass many times before, the initial penetration was always painful. Not to mention that this was her largest dildo yet.

Holding onto the handcuffed blonde's curvy hips, Haylie drove the cock forward, slowly burying its length inside her sisters' stretching asshole. "I'm going to have to change out those bottles soon, sis. They're already almost full." The brown-haired actress began fucking Hilary's anal passage furiously now, the slurping sounds overpowering the steady hum of the tireless breast pump. "Cum for me like a good little slut, Hils. You know you want too."

The younger Duff began to tremble as the orgasm raced through her body, her nipples as hard as they'd ever been while the dildo probed the depths of her rectum farther than ever before. She was shiny and slippery with sweat, and Haylie felt her body weight collapse as best as she could in this position. After slowly withdrawing the enormous shaft impaling her sister's ass, Haylie removed the handcuffs holding the blonde and guided her over onto her back. "Ooh. That..that was so nice, Hay. I don't think I've ever cum like that before. Ever." The 39-year-old smiled to herself as she replaced the two filled bottles with new, empty ones. The two full bottles were carefully placed inside a cooler.

Haylie stepped out of the strap-on and took a vibrator out of her bag. "I'm glad. The fans also enjoy the story card I send with each order. It tells what was being done to you when that exact bottle was taken." The 36-28-35 actress was straddling her sister's face now, her knees on either side as she slowly lowered her bald, dripping cunt down against Hilary's mouth. The younger girl already had her tongue out in anxious anticipation and caught her sister's warm syrup against its tip. "That's my good girl" complimented Haylie as she placed her clit on Hilary's hungry lips while inserting the vibrator into her slimy girl hole. "So well behaved."

The vibrators gentle hum was swallowed up by the brown-eyed blondes juicy pussy, and Haylie guided it in until its protruding knuckle was against her sister's swollen clitoris. It wasn't long before each of the siblings' nude bodies were bucking frantically from climaxing. Haylie from the attention to her slippery hole by Hilary's expert tongue, and Hilary from the combined stimulation to both her vagina and clit by the buzzing sex toy. While still licking and poking at her sister's gooey opening Hilary confessed again "Never came like that. Never."

After a few minutes it was again time to replace two filled bottles with two new ones. "Two more, Hils. A half dozen and I'll be set for today." Keeping her sister laying on her back, Haylie slid a butt plug the size of a softball into her ass then strapped on a new dildo. Not as large as the other but this one was covered in small nubs from tip to base. It slid inside the former pop stars sex opening easily, the bumps adding extra pleasure to the fucking she was about to receive from her older sister. A variety of colorful, stuffed creatures looked on from their perch above the changing table.

"Whatever you say, Hay. Anything." The blonde actress started panting in rhythm to the pulsing suction draining the milk from her glutted breasts.

Haylie smiled.
