"I miss Emily," my mum said, out of nowhere.
I blinked. "Where did that come from?"
"Oh, I was just thinking about how well the two of you got on. Thick as thieves, the pair of you." She sighed, clearly lost in memories of her sister.
"I thought you hated her." Indeed, I couldn't remember her ever being referred to by name before. It had always been 'my bitch of a sister' or... "You always called her a witch."
My mum squirmed uncomfortably. "Well, she was one - sort of. Maybe."
I raised a curious eyebrow. "My aunt was a real witch?"
It was the first time she had visited me since the funeral, although we had spoken several times over the phone. We'd had lunch in town, and spent the afternoon shopping, and had ended up back at my flat for coffee. Elizabeth was out with her boyfriend, fortunately, because I would have found it difficult to explain the weird dynamic between us. As it was, the smell of sex seemed to linger in the air of the flat, stirring a familiar hunger in me, as well as the fear my mum would recognise it - which would just be too embarrassing.
"I-I don't know," she stuttered. "I never believed it. She was always so good at seducing men. Even your father. I never caught them together, but I knew. I could smell her on him."
That was a surprise. My aunt and my dad. I wondered which of them did the fucking. Somehow I could just picture her thrusting her strap-on into his ass... "Uhh," I said, shaking my head to clear away that image. Anyway, my dad died when I was twelve, six years before she made the strap-on for me.
But she had used the magic dildo on someone before she died. "Um, Mum?"
She frowned. "What, Raina?"
"Did you and Aunt Emily ever, ah, -" (Just how do you ask your mum if she fucked her sister?) "- you know... do it?"
In answer, she turned bright red. "No!"
"Oh, please. You could not look guiltier."
She sighed in surrender, and I stared at her, astonished - and not a little aroused. Somehow, amazingly, Aunt Emily had had her way with both my parents. "How?" I demanded. "When?"
"I was upset," she said eventually, "with how much she was influencing you. I went to see her, to tell her to stay away from you. I, ah, lost my temper, said some stuff I really regret. Hurtful. Then she smiled this cold, brittle smile, and said, 'Let me show you what I've made for your daughter.' She went upstairs for a minute, and returned naked. She was wearing a harness with a huge, black cock."
Butterflies fluttered in my belly. I could see where this was going, and the memory of the first time I'd sucked the dildo was sharp. I'd wondered whose pussy I'd been tasting. I'd never suspected it might be my own mother's. Why did the thought of that excite me so much?
"I was shocked, of course," she continued, her eyes focussed on the past. "I was on the verge of storming out of her house, back to the sane world, but there was this evil thought in my head that I hadn't, ah, well, in years, and even though it was my sister wearing it, that cock looked... really good."
I could imagine. "A woman needs what a woman needs," I murmured.
"Ah, yes. Before I knew it, I was feeling it in my hand, stroking it. It felt so real. Like black, porn-star cock. And I wanted it in me. I think I even said that out loud. 'I want that in me.' Emily laughed and ordered me to strip. I wanted to tell her to go to hell. Maybe I even did, but I was soon bent naked over the kitchen table, legs open, like the horniest slut in history."
Just listening to this story was making my clit throb. I could just imagine my aunt delighting in my mother's helpless subservience to the magic dildo. No doubt the thought that one day I would be wearing that same cock, anointed with my mother's holy water, was icing on the cake. "Did you beg her to fuck you?" I asked.
She nodded, blushing. "I don't know what came over me. I just needed so badly for her to -" She hesitated, took a deep breath, and forced herself to say it. "- to fuck me. Emily laughed. Said, 'Who's the bitch now?' And then she was thrusting that huge cock into me, and all I cared about was taking the whole length of it, as deep as possible, even though it was stretching my vagina more than anything ever - well, except for, well..."
"Yeah."
"Anyway, she was soon fucking me vigorously, and slapping my ass so hard it was red for days, and I must have come, like, a dozen times. She left me there, sprawled across the kitchen table, too exhausted to move."
Wow. "Was that the only time?
My mum hung her head in shame. "I was like a woman possessed. I'd never experienced such pleasure before. She couldn't get rid of me. I think I had more orgasms in that one week than the rest of my life. Even after that, I was visiting her every weekend, mainly for the sex but we started to bond again as sisters too, after a lifetime of anger.
I could sit still no longer. "Back in a moment," I said, and hurried to my room. Part of my mind screamed that even considering what I wanted to do was insanely wrong; that sensible part was overruled by the throbbing of my clit. Once the harness was fastened in place, and the black cock projecting from my crotch, the last resistance to the plan faded away.
I returned to the kitchen in the same state my aunt had: naked, harnessed and horny. My mum gaped at me, horror mingled with lust in her expression. "Take your clothes off, Mum," I said, and she nodded, her hands acting almost on autopilot.
I had never considered her as attractive before - at least, I wasn't sexually attracted to her, though she wasn't unattractive. Even now, my desire to have her was more about the wrongness of it. The impossibility of it. The symmetry of it. "Bend over the table," I ordered.
She rewarded me with the same sight that must have greeted my aunt. Wide-spread legs revealing a pussy that was glistening with arousal. "God, you're a horny slut, Mum," I said. "Let me hear you beg for it."
She was quick to obey. "Fuck me, Raina," she pleaded. "I need that cock in me right now."
A fleeting moment's incredulity made me hesitate. Was I really about the fuck my own mother? That whisper of conscience faded fast, however, and with a gleeful thrust, I penetrated my mum's vagina (for the second time in my life).
