We were just sitting down to our Christmas breakfast when my phone chimed. I'd set alerts for messages from Aisha to a neutral tone, instead of the heavy breathing that she'd programmed it for. She had a strange sense of humour.
As it was, Mum and Dad frowned at me for looking at my phone at the table. "It's from Aisha," I told them, and the frowns disappeared. My new girlfriend had been approved. "Wish her Merry Christmas," Mum said.
Aisha's message was full of emojis and Christmas wishes for the family, which I duly passed on.
"I didn't know she'd met you, Sally," Dad commented as I tapped out my reply.
Sal looked up from the mince pie she'd stolen, even though Mum had given express orders to leave them for lunch. "Just for breakfast, before she had to leave. We had coffee and gossiped."
My heart gave a sudden lurch. I'd managed to forget that they'd been by themselves for a bit while I dressed. My mind raced as I suddenly wondered what they'd been talking about. A glance at Sal was enough to know she was hiding something.
"Ask her whether she'll make it for New Year's," she said. When I looked a question at her, she added, "The big bonfire on the Common. She said she'd try and make it down."
This was news to me. I wasn't expecting to stay with Mum and Dad for another week, and I hadn't really planned on returning for the celebrations either.
A local historian had discovered -- or decided -- that our little town had been founded fifteen hundred years ago, and had managed to convince the Council to mark the occasion with a series of celebrations and pageants during the year. It would kick off with a big bonfire and fireworks on New Year's Eve.
"That would be nice," Mum said brightly. "Having the three of you here."
When Dad added his own encouragement I knew it was useless to protest. Sal gave me an impish look. "And tell Aisha to bring that perfume she was wearing the other day. I really liked how it smelled."
Inwardly I groaned. So much for not getting up to any of her tricks.
To my surprise the week flew by. It was good to catch up with friends. The old haunts were the same as ever, but smaller somehow, and strangely empty. As if the spirit imbued in them by the hours we'd spent there had dissipated in our absence.
I was sitting on the gang's old bench by the brook on New Year's Eve when Sal came walking up. "Hey, big brother." She came to stand before me and rested her hands on my shoulders. "You're looking glum. Particularly for a horny bloke who's about to see his girlfriend for the first time in a week."
I glanced up at her, searching her face for a trace of sarcasm. Her look was serious, though. For the past week, ever since Christmas morning, she'd behaved exactly like a twin sister should. Nothing sexual.
So now, instead of the wariness I'd have felt earlier in the week, I was glad of her company. "Glum is how I'm feeling. Loss of innocence, perhaps. This place doesn't feel the same."
She pulled my head against her. The material of her coat was stiff and cold, but I didn't protest. "You lost your innocence before you went to uni. Don't tell me I was your first."
I couldn't help grinning. "Don't worry, you're not going to Hell for leading me from the path of virtue. For other stuff, perhaps, but you can rest easy on that count."
"Speaking of which." She lifted my head and turned it up towards hers. "Your girlfriend's on her way. Dad's gone to pick her up from the station."
My heart gave that now familiar lurch. On the one hand, I could barely wait to see Aisha, touch her, smell her scent, kiss her, feel those full lips against mine, feel her hips under my hands... But my mind also flooded with suspicions. Sal had that impish look again.
I decided to just ask. "What evil plan have you concocted?"
"Evil plan?" Her eyes opened wide. "What makes you think that?"
I didn't think, I only suspected, so I glared at her until she grinned. "What? I like Aisha. She's sweet." Just as my suspicions were starting to settle down Sal licked her lips. "Very sweet."
This time I didn't try to hide my groan. "Sal! You're going to get us into so much trouble. And if you mess up things with Aisha..." I tried to put a note of threat in my voice. Very hard when you're looking up at your little sister like a faithful hound gazing adoringly at his master.
"What are you worried will happen?" She leaned down and kissed me lightly on the lips. I inhaled her scent: something flowery, with vanilla undertones. My cock gave a twitch as it remembered the last time I'd smelled her.
"I don't know. That's the problem. You'll walk in on us again and this time demand to join in?"
"Hmm." Sal's face was still close enough to mine that her breath was warm on my face in the cold afternoon air. "Would you let me?"
I hesitated. The thought had crossed my mind a few times, and resulted in several sticky wank rags. I opened my mouth, but Sal interrupted me with a chuckle.
"Ooh, my big brother's a pervert! Don't deny it. You want to watch me eat out her pussy while you fuck me from behind, don't you?"
My cheeks flushed with a red heat. That was precisely the image that had been in my mind. Aisha on her back, legs apart as she pulled Sal's face into her pussy. Writhing on the mattress, looking up to meet my gaze as I held on to my sister's hips and thrust into her from behind...
My mouth was still open, I realised, and I closed it before I began to drool. My cock was throbbing in my jeans. "I don't think..."
"I do." Sal's eyebrows wiggled. "Leave it to me."
We were having dinner when I saw the first signs of Sal's plan unfold. I was still in a bit of a daze, a combination of my conversation with my sister and the kiss Aisha had given me when I'd run to meet her.
She'd greeted Mum with friendly politeness, but Sal had received a big hug and laughing kisses on her cheek. "We've been texting all week," Aisha confided. "We're becoming firm friends."
"You need to be careful," Sal added. "I think she likes me more than you."
So it was grins at my expense as we sat down to eat. Mum and Dad were going to the bonfire as well, but had decided to only stay until midnight. "Unlike you young lot, some of us have to be up early," Dad explained. Mum sighed. They were expected at a special New Year's do for Dad's work. She'd expressed her thoughts on a company that made plans for its employees on New Year's morning.
"Good luck getting enough sleep," Sal said.
Something about her tone made me look at her sharply. "What do you mean?"
"I mean that you'll probably wake them when you come thumping up the stairs."
