The next morning I woke to see Sarah fastening the clasp of her bra, her clothes gathered into a neat pile at the foot of the bed, and I sat up quickly. "Sarah -- you don't have to go."
A wistful smile. "'Fraid I have a viewing this morning. But I can come back afterwards if you want."
I chuckled. "Are you kidding? Those two --" Amy and Beth were still asleep in one another's arms -- "I'd be in hot water if I let you disappear."
"I'm rather hoping we can all be in hot water again soon," Sarah teased. "And if that bath oil starts to run out, I'll get some more, sort of a house-warming present."
I watched as she buttoned her blouse, then slipped her skirt on, fastening the zip. "You look the very model of professionalism."
"And if I do this?" her voice was teasing as she quickly knelt to take me in her mouth, then got to her feet again.
"Um --" I stuttered, as with a toss of her head and a mischievous grin she was gone.
Beth stirred, stretched. "Morning..."
I leaned to kiss her, then a very sleepy-looking Amy. "Sarah had to work, but she'll be back later."
"What did we bring for breakfast/" Amy wondered.
"I'll go hunt," I winked. "There's bacon in the fridge, and some crusty bread."
"Mm."
A few minutes later I brought bacon sandwiches up, and the girls sat cross-legged on the bed to eat. "What shall we do this morning?" I queried.
Amy gave me a knowing look. "You should save yourself for later, Tim -- Sarah has some catching up to do."
She grinned at Beth. "But I have some other ideas for you and me."
Beth stretched luxuriantly. "Mm, go on."
"Well," Amy seemed a little shy now, after her bold beginning. "That toy -- there's nothing to say you can only use it on yourself, is there."
Beth's eyes widened. "Mm, Amy, I like these ideas of yours."
Amy fished in her bag, finding the toy, and Beth laid back, parting her thighs. I felt a thrill of my own as Amy started the toy's low buzz, then hesitantly touched it to Beth's body. "Ohh..." Beth breathed, "that's nice, Amy."
Amy must have been feeling bolder again, stroking her other hand up the soft skin inside Beth's thighs till she met warm wetness. "I know you like it when Tim does this," she murmured, pressing the tip of a finger a little way into Beth's opening.
"Mm -- oh yes -- please --" Beth gasped -- "do it like he does."
Amy replaced one finger with two, sliding them deeper, her face betraying how turned on she was with what she was doing to Beth. She pressed, circled the toy on Beth just above where her fingers were penetrating, and Beth moaned, flexed her hips. "Mmm, Amy, I'm getting so close now."
I leaned over to whisper in Amy's ear -- "Just bend the tips of your fingers a little..." and she nodded. "Oh -- oh god, yes --" Beth gasped, then her body tensed, shuddered, a spurt of clear liquid splashing on Amy's fingers, dripping onto the sheet. "Mmmm..."
Aftershocks of pleasure made Beth's body quiver again, then finally she relaxed. "Wow, Amy, that was... mmm..."
Amy carefully drew her fingers back. "You tightened so hard on me, Beth, I can still feel it, no wonder Tim likes it so much when he's in you..."
She wrapped her arms around Beth, and I joined them, stroking Beth's hair. We must have drifted off to sleep again, and the next thing I knew was the sound of the front door opening, Sarah's voice from the hall. "Hi, I'm back."
We made our way down to the kitchen, and I glanced at the table, a bulging white bag next to a cardboard bottle carrier. "What's all this...?"
Sarah grinned. "I closed the house sale, so I thought we could celebrate. Fish and chips, and a bottle of champagne."
"Well done," I nodded. I found cutlery, glasses, and saw Amy blink, startled at the loud 'pop' as Sarah eased the cork from the champagne bottle. Beth sipped at her glass, and sneezed. "The bubbles always go up my nose," she mock-complained.
When we'd finished eating, Sarah gave me a knowing look. "OK if I look a little less professional again?"
Without waiting for a reply, she quickly shed her clothes, finishing by dropping her panties on the worktop. Beth nudged Amy -- "Remember when you were worried Sarah might find yours in the kitchen?"
A grin from Amy. "I've not forgotten -- and how Tim wound us up about it."
"Anyway," I cleared my throat. "Time we found our way back upstairs. Would you like that bath now, Sarah?"
She shook her head. "Maybe later?"
When we reached the bedroom, Amy and Beth took their usual side of the bed, and Beth threw Sarah a grin. "We did make good use of this morning -- but we saved a treat for you too, Sarah."
Sarah chuckled. "I guess that means you, Tim," she looked at me with obvious anticipation.
She moved to her hands and knees on the bed, looking back over her shoulder at me and swaying her bottom invitingly. I knelt behind her, pressing my tip to her entrance, and she pushed back slowly, deliberately, so that I was in her. "Mmm..."
I put my hands on her hips, and I heard the smile in her voice. "You know how I like to be touched, Tim."
I gripped her more firmly with my fingers as I thrust into her, and she moaned. "Yes -- like that -- oh, my bottom, too."
I took her at her word, moving my hands to her bottom, my thumbs pressing into her as I thrust again. The movement let me see into her cleft, the pink star of her other opening tantalisingly visible, and I remembered Amy's words of a few days ago when Beth was imagining me spurting my warmth against her: I definitely want Tim there soon. It was something even Beth and I had only tried a couple of times, but I wondered if it was one of Sarah's preferences.
