"Tiff, be a dear and run to Mum and Dad's bedroom and get the Vaseline from our bathroom cabinet," Wanda said.
Tiffany was gone in a flash and back just as quickly. She knew what her mom wanted; she un-capped the jar, and scooping a generous amount of the jelly out with two fingers, she slathered it onto Wanda's winkled bumhole. Her fingers went in easily, and she wiggled them around, coating the interior of Wanda's rectum. Wanda cooed encouragement; she loved having her ass played with.
"Right; slide out, sister, so I can lube you up," Tiffany told her twin. Krystal did so, and Tiff added another double-fingerful of the slick jelly to the already cunt-juice soaked latex rodger.
"Put a bit extra on the tip, pet," Wanda requested, peering over her shoulder.
Krystal positioned the greasy tip of her "cock" against her mum's delicious-looking rectum and with a hard, firm thrust, sank it all the way in, up to its rubber ball-sac.
Wanda was in ecstasy; she'd come to fancy anal sex versus vaginal over the years. "Oh, sweetheart, YES!", she cried, humping back at her daughter like a bitch in heat. She stared back over left shoulder, eyes blazing with lust. "Fuck it hard , dearest, mummy can take it...make it gape, sweetheart!"
Krsytal was more than willing to comply; her trim hips were a blur as she rammed her thick butt-stretcher in and out of her mom's welcoming shitter with abandon. Wanda's massive jugs swung heavily beneath her in time to Krystal's thrusts, and her abundant ass-flesh wobbled like gelatin every time the youngster's thighs connected with that lovely lily-white globes.
Tiffany was tired of being left-out of the action: sliding beneath her mom, she fastened her lips on Wanda's upthrust clit and sucked hard. She was rewarded with a spurt of delicious woman-cum....
Krysta's turn...
Tiffany and Krystal switched places, but instead of sucking her mom's cunt, she lay beneath her and nursed on her maximum-sized nipples. Krystal didn't bother fucking Wanda's dripping puss; she went straight for her gaping ass-hole and shoved it deep. She'd learned well from watching her sister earlier, and Wanda was the beneficiary: there was no clumsy fumbling or time wasted finding a rhythm; she was bale to deliver a hard, solid butt-fuck right from the start.
"Butt-fuck me, my sweet baby," panted Wanda, wild with lust as she felt her daughter shove the strap-on up her ass. It was promptly wedged in to the hilt and Krystal held her mother's shoulders as she hunched over her and began fucking her butt hard.
Her mom's lush butt-cheeks, so deliciously-framed by the straps of her suspenders,lent the youngster additional inspiration.
They fucked like that for ten minutes more before Krystal got a very nasty inspiration. She eased the shit-speckled monster dildo out her mom's ass and went round and stuck it in her mom's face.
"Suck my willie, mom," she grinned, "Suck my shitty willie, you ass-fucked bitch!"
Wanda felt a new surge of lust at her daughter's dominant attitude; without hesitation she gobbled the ass-flavored dildo into her mouth and sucked the slippery latex phallus clean.
Tiffany's eyes bugged-out at this depraved spectacle; who knew their mother was so depraved?!
"I love it," Wanda hissed, "I love licking this big dildo after you've fucked my ass with it Krystal. Your mummy's an anal whore, a nasty slut who gets-off getting banged by her own daughters!"
