"Let's have a hot tub party for Christmas Eve."
"Won't it be too cold?"
My wife Mallory always took turns with her three sisters hosting a big family party that rolled nicely into the Santa hour. As none of us had kids, it was a great way to see the holiday in. Whoever hosted Christmas Eve then got a dinner invitation to another sister's home for Christmas, and New Year's Day at the third (two of the sisters, Krista and Claire were twins who shared a condo). The 24th was just a week away, and Mallory had not shown any interest in planning a party. This was quite unusual for her, but since we had shared sexually with her sisters and our neighbours on National Nude Day in July, she had been very withdrawn, not visiting with family or friends often.
She was spending lots of time with our new friend and co-worker, Amal. This fine African refugee had moved in with us when her husband had thrown her out for adopting Western ways. Mallory and Amal had explored lesbian love together. Occasionally, I joined in. More rarely, Mallory switched beds and I had Amal all to myself for a night. I worried that Mallory might be either too obsessed with Amal, or ashamed of what she had shared with her sisters.
"The forecast has a chance of wet snow, but mild weather," Mallory said cheerfully, handing me a cup of hot cider. "Anyone getting chilly can jump in the tub."
"Last time your sisters were here..." I started, but instantly regretted.
Fortunately, Mallory just laughed, lustily, right from her toes. I saw a twinkle return to her eye which had been missing for months.
"You dirty old man, just wanting to fuck my baby twin sisters again."
Claire and Krista were barely in their twenties, just a few years younger than Mallory. I was considered a cradle robber by her parents, who were barely older than me.
I was silent for a moment. Mallory wriggled her nose deep in thought, and then grinned even wider. "Oh, so you want by big sis instead?"
Bridget, always called B, was an openly bisexual domme, and had taken a leading role first in our fantasies and then in realizing dreams. Mallory had started our slide into polyamory with fictional tales of seduction by B, first of her, then of me. By Earth Day, the story expanded to include all four sisters. But until July, that part had all been imaginary.
Still, I said nothing. "Oh," Mallory stretched her smile wider, her whole body surging up and towards me. "You want them all."
Now it was my turn to smile. "I still can't get the image of the twins chanting 'orgy, orgy, orgy' out of my mind. I picture that more than the sex that followed."
"I can see how much you liked it," Mallory observed, her eyes now focused on my lap, where my surging cock was evident inside my pants. She flicked up and made fresh eye contact, bathing me in her warm smile. Well, at least she wasn't depressed.
Without another word, she dipped forward from the waist, her fingers grabbing the waist of my pants and dragging them towards the floor.
"Are you wishing it was Amal doing this?" she asked, and then flicked her tongue out, teasing the tip of my growing organ, which bobbed its head in agreement.
"Or maybe our little old neighbour lady, Mrs. Ludweg?"
"Who knew that seniors could give such great head?"
"You liked how her tongue circled at the base of your helmet?" Mallory demonstrated the maneuver, and then giggled. "I have a confession to make."
"What?"
"I've invited the Ludwegs to use the hot tub a few times while you've been at work, and Mrs. L has given me some lessons. It turns out that Mr. L having a small cock that takes lots of effort to suck hard, and then even more to come, makes him a great practice dummy."
My cock seemed pleased by this news, or maybe it was just reacting to the way that Mallory was fondling my balls while tonguing the underside of my shaft slowly from the root to the head, and then back again.
"But your cum tastes sweeter. Mr. L is salty tasting." A shiver ran through Mallory's body. She bobbed her head down over my fully erect rod, swallowing it into her throat, but quickly pulled back to speak more.
"Their daughter Alisha, though, tastes really sweet. She's joined in the practice a few times too." My balls throbbed in Mallory's palm. "Oh, I can tell you like that idea."
The image of this athletic young woman swallowing her elderly parent's load suddenly appearing in my brain, complete with a slimy cum trail from his reddened tip to her plush lower lip. Although she had deep throated him the first time we had met, that whole experience had taken on a dream like quality, and I wasn't totally convinced that it, and the Nude Day orgy, might not be figments of my imagination, despite the undeniable fact that I woke up most mornings with not just Mallory, but also Amal, in my bed.
"You mean Aly s...su...sucks her Dad's cock?" I stammered, seeking confirmation that events had really happened.
"What's wrong with that? You get off watching my sisters and I eat each other's pussies. Aly is a consenting adult. Maybe if we invite her over, you could be the beneficiary of the lessons her Mom gave her," Mal chuckled. "You already have been, you know. I'm surprised you didn't notice I've learned a few tricks."
In demonstration, Mallory lifted the tip of my cock skyward while she crouched lower and rolled her tongue all around the root of my shaft and then sucked each ball into her mouth one at a time, slowly, also rolling them around.
"Maybe the Ludwegs will bring Aly?" I managed to mumble.
