Third part to the series, again unchecked and unedited so there will be typos, etc. Hope any errors in the text aren't too off-putting.

***
I boggled, stunned by what I was looking at.
My mother's fingers were tight against my wrist, so tight it hurt. Not that I was paying any attention to the pain, my head was too full of seeing my sister in a bra and briefs. She was on our parents' bed, our father's erection in her hand while she slowly stroked its length, her eyes on me.
From alongside me I heard my mother murmur: "All right, just trust me."
I swivelled my face towards her. "Mum? Oh no," I said through a croak.
Her eyes were wide and full of empathy. "Uh-huh, I know, didn't expect to see that - did you, Nathan?"
I heard an inarticulate gurgling sound issue forth from me. I gawked at my mother for a couple more seconds, then set my attention on the shocking, unbelievable sight of my sister sucking our father's cock.
Another chocked sound came out of me when I saw Annabel's eyes glinting with devilment. She was taunting me with her expression, her pretty face misshapen because the girth of the cock was stretching her lips.
Annabel held my gaze as she came up off the cock, gasping and coughing, drool a silver hawser connecting her mouth to her own father's erection.
I continued to stare, with my brain steadfast in its refusal to accept the reality of the scene.
"I'm going in there," I heard my mother say. She paused and let go of my wrist, adding: "Trust me, it's all perfectly fine."
As she went, my mother let the gown slip from her shoulders, the pleasing view of her feminine shape from behind obscuring the awful vision of my father's brutal-looking cock as my sister licked it from balls to tip.
"Here, let me have that," my mother said as she got onto the bed.
I saw the mollusc of my mother's meaty twat nestled in the concavity between the tops of her thighs as she knelt on hands and knees, rump towards me, her hand going to my father's dick.
"Take your brother to your room or something," my mother went on. "Talk to him. He looks like he's had a shock."
My sister giggled and moved to kiss our father before she got off the bed. I watched, transfixed, appalled and fascinated during the car-crash moment in which I saw my sister's pink tongue slip and slide with our dad's.
Then Annabel came to me, smirking as she walked, our mother behind her taking the cock between her lips.
"You've been fucking our mum," Annabel said.
"Bella, Jesus," I gasped.
"He licked my arse," I heard my mother say. "I'm so wet. I'm sodden. Do you want to do it now?"
As my sister moved in front of me, our father growled: "She's been sucking it since you left. If I put it in now, I'll come."
"Come on," Annabel said.
I didn't move. Instead, I carried on staring into the room, the couple on the wide bed, my parents, both naked.
"Nathan," my sister insisted as she tapped my arm.
She had to grab my hand a forcibly tug it to get my attention.
"We're going to my bedroom," she said.
It took words from our father to spur me into movement. "Fuck off," he said, focussed on me. "Go with your sister," he added.
My mother was kneeling next to him, her hand moving slowly up and down the length of my father's hard-on, her other hand caressing her breast.
"Go on, Nathan," my mother crooned. "Go, sweetheart. I'll come and talk to you later."
That's how, for the second time in five minutes, I found myself being led by the hand by a female member of my family.
"Your-fucking-face," Annabel giggled when we stepped into her room.
I managed to ask: "Bella, what's going on?"
She shrugged and grinned and said: "Our mother and father are going to fuck."
I closed my eyes and pushed the heels of my hands against the lids until starbursts of light exploded across the darkness. I sucked in air, clenching my teeth while my fingers then curled into fists, tension coiled within.
I sucked in air and then held my breath, cheeks ballooning as I hissed it all out.
Then I was ready, almost, to face my sister.
"Bella, Jesus-fuck," I spat, "you were sucking dad's cock!"
"You've been fucking mum," my sister shot back.
"But ... I mean ... Fucking hell, Bella, what's happening to us? This is just so fucked. How long have you and dad been...?"
My sister's face softened as she paused before taking my hand.
"Come on, let's talk," she said, leading me to her bed.
We sat side by side, my attention on the carpet near my feet as Annabel spoke, my head clearing of confusion but filling with questions as she told me her side.
"It's been about a year," my sister began. "Mum started it off."
"Mum? But how? Fuck, Annabel ... I mean, why would she do that?"
My sister rolled her eyes. "Because she's kinky. You've only seen her being our mother ... Well, until Saturday that is. You've saw more of her then - didn't you, Nathan?"
I blurted: "You know about that?"
Annabel laughed. "Yes, of course. Why do you think I stayed at Mary's that night?"
"Because she's your best friend," I said.
"Yeah, and because mum wanted me out of the way."
Annabel paused to let it sink in.
Then she said: "She made out she was all offended by your porn, right?"
I nodded.
"Listen, she loves sex. Everything about it. She wouldn't care about you looking at that stuff. It might piss her off because she wants all the attention, but, believe me, Nathan, our mother's about as fucking dirty as they come. I bet she made a big thing about her being 'mummy' and how much she loves you."
I stared at Annabel, shocked to my socks.
"I'm right, I can tell just by looking at you. She's like that with me. She talks about how I'm a good girl for fucking daddy and how they both love me."
"Jesus, Bella," I said, breathing out the shock.
"It's fucking horny I have to admit. She knows how to do it. She knows what to say."
I knew what my sister meant. My mother's weird way of talking had worked on me too.
"Don't get me wrong," my sister went on. "I love being with dad. It's like mum says, it's sex and love. I really get off on what we do. I love dad and I love it when we're fucking. I love it when mum's there, too-"
I burst in with a gasping, "You and mum and dad? Together? Fucking hell, Bella!"
"Uh-huh," my sister confirmed with a nod. "She watches us do it. She plays with herself when I'm with dad. She tells us what to do sometimes. It's really-fucking-hot when she gets going. The things she says..."
When Annabel paused, I asked a shaky, "Dad knows I've fucked her?"
"Yes, sure, of course she told him about it. In fact, he knew before you did. He knew she was planning to do it."
"I thought he'd kill me," I said. "I mean, like really kill me, Bella."
"I told you, Nathan, you don't really know them. They've been great parents. They never hit us, they never swore, we got presents at Christmas and birthdays, they took us on holiday..."
I thought about it while my sister sat beside me. Annabel stayed quiet, giving me time.
"They really have been fantastic," Annabel said after a time. "Now you're seeing them as they really are. Mum doesn't hold back. Now you're having sex with her..." My sister grinned and let out a low chuckle. "Well, you probably know what I mean already. You've been with her. You've seen it yourself."
It was a surprise to feel myself grinning along with my sister. I said: "I know what you mean. I couldn't believe it when I first heard mum swear. She even said cunt."
Annabel's grin turned huge. "Mum's got a mouth on her," she said. "I bet you shit when she said it."
Being with my sister as we shared observations and opinions made it feel like old times. The shock faded a little, replaced by a cosy intimacy between siblings as we talked about our parents' foibles and flaws. The difference being we were discussing our mother's sexual deviance, not just an innocuous quirk. It was an odd conversation, but one which took soe of the weirdness out of the situation because it was Bella, my sister, and, regardless of the rivalry and teasing, we were close.
"She planned it," I murmured when a silence fell between us. It was difficult but I was starting to process it all.
"She did," my sister confirmed.
"And with you and dad...?"
"She wanted it to happen," Annabel said after another pause. "You think dad's the boss? Wrong. It's her. He's soppy on her and does whatever she says. She's just a filthy bitch. I told you before, she loves sex. Just-fucking-loves it."
"But you said you liked it. With him..."
