"You're looking very pleased with yourself." Aisha leaned her head on my shoulder.
I probably was. I had every right to be, I thought. Two hot, gorgeous women wanted to fuck me as often as they could: Aisha and Sal, my girlfriend and my twin sister.
We were on the train, travelling home from visiting Sal. Ever since New Year's the three of us had been getting together regularly -- to hang out and to have sex. I was probably the happiest I'd ever been.
"Do you realise," Aisha continued, "that it's been nearly six months since we first fucked?"
"Six months?" It felt longer, but the time had flown by. "A six-month shaggiversary. What's that, clingfilm?"
She nuzzled against my neck. "Shaggiversary. I like it." She raised her head to look at me. "We should celebrate. Make it special."
"It's always special with you, babe." My cock gave a twitch in my shorts as a memory from just that morning came into my mind...
Aisha leaning forward against the shower wall, pushing herself back onto my cock, her breasts swaying with her motion. My cock sliding in and out of her, glistening with the cream of her arousal. Sal pressed against my back, her small breasts noticeable only by her hard nipples against my skin. Her hands stroking my chest as the water cascades down...
I hastily came back to the present as Aisha kissed my neck. "Of course it is. But how about we make it even more special, by not having sex until the first?"
It was March 24. "That's a week away!" If my cock could have spoken, it would have been complaining out loud. "You want us to keep our hands off each other for a whole week?"
"Imagine how special it will be."
I tried to bluster through. "Like you could manage a week without us having sex. You know you want it just as much as I do."
"Hmm." She smiled. "I'll manage. Maybe you're not as irresistible as you think you are."
I looked down at her and met her cool gaze. "Really?"
"Really." Her voice was firm as she rested her hand on my thigh and squeezed. "And no wanking either. I don't want your cock to be rubbed raw during our celebrations."
"Great plan, babe," I sighed. "Special. So special."
The next week was the slowest of my life. Even worse than the time Mum and Dad had dragged Sal and me off to camp in Finland when we were eight, and it rained every day, and even so we got eaten by mosquitos.
Time dragged by. Classes, coursework, more classes. After the first two days I began avoiding Aisha. I knew I wouldn't be able to keep my hands off her if we were together. I saw her once from a distance, sitting with some friends and laughing without a care in the world, and a sudden thought crept into my mind.
Not as irresistible as I think. Is she growing tired of me?
Worry gnawed at me as the week crawled its way forward. Classes and coursework. Hanging out with friends and trying not to mope over Aisha. More classes, more coursework. Lots of time at the gym, punching the bag, running off the worry and frustration. Redoing my coursework because my mind hadn't been on it. More worrying. More running.
The night of the thirty-first was unending. I tried not to think of Aisha, of seeing her again, stripping her naked and plunging my tongue into her snatch, holding her against me as she squirmed...
And then I tried not to think about what she was doing. She was visiting her parents, but was she seeing anyone else while she was there? Someone she was interested in?
She'd sounded her usual self in her messages, and the two times we'd phoned. But there were tiny doubts that nestled in my mind, burrowing down and refusing to go away.
Is she done with me? I know she thinks I should be more serious about my studies. Is that it? Does she think I'm not serious enough for the long term?
I'd never really thought much about the future. Now I started to worry that I might not have one -- at least not with her.
Alone in my black room I thought about calling Sal. But it was late, and I wasn't sure I'd get a sensible reply from her. Sal loved to tease me, particularly where Aisha was concerned.
And would Aisha have even said anything to my sister? I doubted it.
In the end I stayed up late and did more coursework. I managed to get a few hours sleep, then it was out for another run. Aisha wouldn't be back from her parents until mid-afternoon.
I went straight from class to her place. She had a unit of her own on the ground floor, with a kitchen-living and separate bed and bath. Friends of her parents had done a Homes Under the Hammer-style buy-to-let thing, and they rented it to her at the friends and family rate. Luxurious compared with having to share a kitchen and bathroom for four other guys like I did, so of course we spent most of our time at hers.
Aisha opened the door and took my breath away. Her arms came around me and she gave me a snog that almost had me cumming in my shorts. My heart lurched.
See? I was just imagining things.
Even so, I made a firm promise to myself to a be better boyfriend.
In the meantime, my cock was pulsing. I squirmed away from her, breathlessly. "Don't want the past week to have been for nothing."
She laughed and drew me inside. Moments later we were on her bed, hands under shirts and stroking naked skin. In between kisses we muttered how much we'd missed each other.
I'd just wormed my hand under her bra and was kneading away at the warm globe I encountered there when her phone binged insistently. Aisha pulled away, a confused look on her face. "That's my calendar," she said, reaching for her phone.
"Probably telling you it's time to take off those clothes." I didn't let go.
But she was shaking her head. "Fuck! I have a lecture. I forgot. Last week's was rescheduled."
"What?" I couldn't believe it. "Now?" Groaning, I sat up. Aisha wasn't going to miss class. She took her course too seriously for that. "At least tell me it's online."
"It's online," she replied, straightening her clothes and giving me a quick kiss. "But it starts in a minute. Will you... will you be alright?" The look on her face was one of genuine concern.
I affected a martyred sigh and rose, adjusting myself deliberately. "That's alright. I'll be waiting in the other room."
"Thanks, babes." She planted herself at her desk and flicked on her laptop. Taking up her headphones, she shooed me away with her other hand. "Now go! I don't want my Tort Law class to get distracted by the sight of your bulge in the background."
I slunk out, tail not so much between my legs as throbbing in my shorts. I admired Aisha's discipline and her dedication to her studies, but right now I wished she'd put me first for once. Or that her class had been half an hour later.
I sank into the chair next to the window and tried to think of other things. I'd just completed a puzzle on my phone when a tap on the window drew my attention. I looked up and saw a pale face with a big grin.
"Sal!"
I hurried to the door and let her in. She was in her usual outfit of sweater, skirt and knee-high boots. A weekend bag was slung over her shoulder, with her coat sticking out. "Hi, big brother!" She reached up on tiptoes and kissed me on my cheek. "Mum and Dad sent me to check on you."
I closed the door behind her and followed her into Aisha's living room. "What do you mean? There's nothing wrong with me."
"Oh, I know that." She dropped the bag in a corner and turned to face me. "But they say you've sounded sulky all week, and they think something might be up between Aisha and you."
"There's nothing wrong," I repeated, pushing down the memories of an endless night.
Was I really that sulky?
"Aisha and I were both just busy."
"Yes, she mentioned she'd barely seen you." Sal ran her finger up and down my arm. "That she missed getting naked with you. Feeling your cock..." Her finger stopped and she turned a pair of solemn blue eyes on me. "I know what she means. I miss it too."
My cock had barely had a chance to subside, but now it was showing an interest again. I tried to avoid sounding bitter as I explained that Aisha was in the other room, following an online lecture.
"And you'd expected to be fucking her right now, weren't you?" She pressed herself close. "How about you begin with me instead?" And she put her arms around me and pulled me down to her face. "I haven't had any sex since the last time you two visited me. That's a whole week."
I groaned. "I know! Neither have I." I pulled away. "But we can't. I promised Aisha." My pledge to be a better boyfriend was still fresh in my mind.
"She can join us when she's done." Sal's hands were at my belt, fumbling with the buckle.
"Stop it!" I pulled her hands away and stepped back.
She paused and looked at me sternly. "This is happening, big brother. I want to fuck, you want to fuck. What's the problem?"
"The problem--" I began, but she interrupted me.
"Because you're not the only guy with a cock. I could probably find someone else." She stepped back. "Is that what you want? Not to fuck me again? Because I'm happy to walk away from what we've got going on."
"No!" It came out in a squeak. I tried again. "No. I mean, yes, I do. I do want to fuck you. But after Aisha. Please?"
She went to stand by the window. I saw her eyes move as she scanned the people on the street outside. "Never mind. I know when I'm not wanted." She pouted. "Aren't there any hunky guys around here?"
My mind raced.
Is this where it all ends? Am I going to have to choose between my sister and my girlfriend -- my girlfriend and my sister?
My nerves were on edge. After the past week and the sleepless night, the greeting Aisha had given me had lulled me into a belief that everything was back to being great. Greater than before, even, now that I'd realised how much Aisha meant to me.
But with Sal threatening to find someone else, it suddenly came crashing down on me that I didn't want her to. I didn't want her ever touching another guy.
More importantly, I didn't want her to ever stop touching me.
Am I in love with my own sister?
It sounded strange, considered like that. After all, Aisha was my girlfriend, and I was madly in love with her.
Is it possible to be in love with two girls at the same time?
I didn't know the answer. What I did know was that what I felt for Sal wasn't just brotherly love, and it wasn't just about the sex either.
The realisation hit me like a kick in the guts.
And now I'm caught between the two of them!
