The weather had turned much colder, and now that Beth and I didn't have lectures, we spent most of our time in the kitchen, warmed by the Aga, or in the book room with a roaring fire going. Sarah grumbled good-naturedly about still having to go out to work, but when she arrived home there was always a meal on the table - Beth and I tried to outdo one another with something from one of our recipe books - and welcoming arms.
We spent the evenings deciding on our decorations, planning food, and as the days became even shorter, we made trips into town to get baubles, tinsel, jars of cranberry sauce, all the treats to make Christmas really special. "And next year will be the little one's first Christmas," Beth pointed out.
Sarah nodded. "I'm feeling a little apprehensive about the giving birth part, though," she confessed.
"We'll be there with you," promised Beth. "I don't care even if it turns out to be the night before the wedding."
Sarah leaned across to kiss her. "Love you."
She looked down at the list. "Anyway, what's next?"
"We can get our tree on Saturday," suggested Beth. "There's a place the other side of town."
I concealed my sigh of relief from the girls. I'd been wondering how to get us all out of the house that day so that my Christmas present to them could be delivered, and a trip to get our tree - they'd surely be tempted by a diversion for hot chocolate and marshmallows - would allow plenty of time.
Saturday came, and I glanced at my watch as the girls giggled in the shower. We were in the car just in time, and I relaxed. "So what sort of tree do you want?"
"It has to have a sticking-up bit on the top for the angel," Beth enthused.
Sarah nodded. "Do we dare have real candles? Mum used to have sort of metal holders that clipped to the branches, I loved those."
My mind flicked back to one particular evening in front of the fire. "Definitely candles - we just have to not leave the tree without someone keeping an eye."
We reached the tree place, and the girls wandered through the bundles of variously-sized trees wrapped in netting, brushing their fingers over needle-covered branches. "They smell gorgeous, don't they," said Beth.
"I think... this one?" pointed Sarah. "It's got the bit you said on the top, and it's just tall enough for the book room."
"OK," I grinned.
The man selling the trees helped me get ours into the car - "Hey, it tickles," protested Beth mildly as the top of the tree slid between the two front seats - and I glanced at the girls as we pulled back onto the road. "Hot chocolate?"
"Mm, please."
Our destination was a small craft shop and café just off a crossroads out of town, the road winding between trees before reaching the small village. I parked, and we made our way inside, getting a table. "Anything to eat?" the girl serving queried, and Sarah looked at me hopefully. "Ham and tomato toastie sounds amazing."
Beth nodded. "Think the cold makes us more hungry - and one other thing, right, Sarah?"
"OK - three of those then," I confirmed. "And could we have some pickle on the side, please?"
Sarah grinned as the girl went to fetch our food. "Thanks, Tim."
Our toasties lived up to their promise, and Sarah quickly finished hers, spooning pickle generously on to each mouthful. She sipped at her hot chocolate, and Beth chuckled, reaching across to catch stray whipped cream from Sarah's upper lip with a finger, flashing her eyebrows at us as she sucked her fingertip. "Mm."
We looked around the craft shop for a few minutes, then Beth ventured, "Shall we get going? We can get the tree up and start decorating it this afternoon."
I took my time on the journey back, and when we pulled into the drive, there was no sign of activity, only an inconspicuous new electrical switchbox on the outer wall of the house by the kitchen. "Can the tree wait a minute?" I offered. "I have a surprise for you two."
"Sure. Where do we have to go?"
"Kitchen first, then you'll have to close your eyes."
The girls complied, and I guided them carefully through the utility room and into the conservatory, making sure Sarah didn't stumble. "OK, you can open your eyes now."
Beth gasped. "Oh, wow."
Just outside the double doors leading from the conservatory into the garden, on an area of wooden decking, stood a generously-sized hot tub, wisps of steam rising from the water into the chilly air. "Like it?" I grinned. "We did talk about it ages ago."
"Best Christmas present ever," grinned Sarah. "Can we try it?"
"Of course," I nodded. "But there are some rules."
Beth pretended to roll her eyes. "Go on, then."
"Rule one, no swimming costumes or trunks, not for us, not for guests," I grinned.
She blinked, then a thoughtful smile crept across her face. "Actually I quite like that rule."
Sarah had already started to unbutton her blouse, unhook her bra, and Beth followed suit. "Same rule for you," she wagged a finger at me, raising one eyebrow.
When we'd finished shedding our clothes, I unlocked the doors, pushing them open. "You two first, then."
The cold air from outside made the girls' nipples hard, areolae crinkling, and Beth shivered. "Hope that water's as warm as it looks."
She held Sarah's hand as they climbed in, sitting side by side with the water lapping at the top of their breasts. "Mm, this is perfect."
I joined them, sitting facing them, stretching my arms along the edge of the tub. "Definitely."
"Are there any more rules?" Sarah queried.
I puzzled for a moment. "Um, no peeing, like a swimming pool?"
"Are you sure?" Beth's expression showed amusement and anticipation, and she reached for my hand, holding it between her thighs under the water. I felt a stream of warmth flowing against my skin, and Beth smiled knowingly.
"That gives me an idea," I murmured, lifting my foot to slide it between her thighs, feeling a last spurt of warmth before my toe made contact with her, brushing the hard nub I encountered. "Oh god," gasped Beth, "that feels amazing."
Sarah leaned closer, sliding her arm round Beth's shoulders and kissing her, then starting to stroke her breasts under the water with gentle fingers. I felt Beth's hips flex against my foot in response, and after a few moments she shuddered, closing her eyes, the surface of the water rippling. "Ahh..."
"Wow," breathed Sarah, her fingers moving to touch herself. Beth beckoned to me, and I knelt in front of them, hands now caressing Sarah's breasts, nipples while Beth and Sarah kissed. Sarah's fingers moved more urgently, and she broke the kiss, Beth watching delightedly as Sarah's face showed the ecstasy she was feeling. "Mmm..."
