My life flashed before my eyes. What had I done? How was I going to explain this? I wouldn't be able to; I mean, my nephew had his cock balls deep lodged in my slut ass and I was moaning like a bitch in heat. Not with twenty of the best lawyers would I be able to talk myself out of this one. In the blink of an eye I could see this incident ruining my entire life; being branded a pervert and an incestual slut, my family and friends would turn away, if word got out I could lose my job. I tried to get up, causing Malcolm's cock to slip out of my ass briefly. He seemed to be unaware of her presence or he just didn't give a fuck, because he put his hand on my torso, pushed me back down and reinserted his dick back into my ass and started fucking me with renewed vigor. I wasn't planning on just letting him fuck me with my sister watching us - and probably about to kill me - but once he started slamming his hard cock into my ass again, there was little else I could do but lay there, moan and brace for the next impact.
"Malcolm, what the fuck?" Casey shouted. Malcolm, who had his back to her, now turned his head in surprise, confirming my suspicion that he simply hadn't heard her the first time. Once he laid eyes on her, I could actually feel his dick getting even harder in my ass, stretching me, even though he wasn't moving anymore. Casey, who was wearing a very short, red skirt and a black top - revealing several inches of her tummy - kept looking for a few seconds, glancing at her son and me alternately before turning away in disgust and storming out of the room. Malcolm turned to follow her and pulled his dick out of my slut ass in the process; with his fat, throbbing cock leading the way, he headed for the living room, leaving me there, with my ass spread lewdly open. I quickly closed my legs and hopped off the table as I watched Malcolm disappear; once he was out of sight, I heard some minor struggling and some angry whispering coming from my sister, followed by some whispering coming from Malcolm. I looked around for my clothes, remembering that Malcolm had taken them off into the living room. Realizing I was as much to blame as Malcolm, I wanted to go after him. I didn't want him taking the fall for this alone.
So, with nothing to cover myself up with, I tiptoed towards the living, finding it somewhat odd that I couldn't hear any more struggling or whispering. Imagine my surprise, as I peeked around the corner, when I saw Casey leaning with her back against a wall, her skirt pushed up and her panties down and Malcolm's index and middle finger lodged knuckle deep into her sopping cunt. They had been out of sight for less than twenty seconds, she couldn't have put up much of a fight!
"Oh my god!" I uttered out of shock and surprise, immediately feeling uncomfortable for having caught them in the act. But to my even greater astonishment, they didn't seem to be impressed, worried and distracted in any way by my presence. I could actually hear the sopping sounds of my sister's cunt being worked over by her son's fingers. Neither of them seemed to have any reservations about what they were doing.
I just stood there, butt naked, watching Malcolm finger fuck the shit out of my sister - his mom! - in my own living room. Apparently I wasn't the only incestual slut in the family. Realizing I was in less trouble than I had imagined, I relaxed a little bit, taking a small step closer to the spectacle. If they had no trouble doing that in front of me, then I figured I shouldn't be ashamed for taking a closer look either. I watched as Casey moaned and slithered against the wall, holding onto her son's shoulders with both hands. Her screams were getting louder and sluttier with every passing moment; she wasn't going to last much longer.
"Oh Malcolm... oh, yes... oh fuck... oh... OOOOOOOHHH!" she screamed as she clenched her eyes shut and her body convulsed several times. After fingering her through her orgasm, he pulled his fingers out of her, rather rough, causing Casey to gasp.
Without missing a beat - while Casey was sinking to her knees - Malcolm asked her, "Mind if I finish her?" referring to me with a hand gesture. Casey didn't reply - it was clear to all that it had been a rhetorical question.
As Malcolm turned to face me and started walking up to me, I backed away and whispered, "What do you think you're doing?"
"Finishing what I started," he replied insolently, grabbing his cock and wanking it, getting it fully erect again in just a few strokes.
"Wait a minute..." I whispered, still backing away into the dining room.
" ... you can't just pick up where you left off, after doing... her."
"Sure I can," Malcolm said, still following me.
"We should probably talk about this," I said as I bumped into the table with my ass, finding myself right where back where we started.
"Yeah, we probably should," Malcolm said, his voice dripping with sarcasm, as he lifted me up and sat me down on the table, pushing me onto my back as he placed the tip of his cock against my cunt. Somewhat relieved that he wasn't going after my ass again, I suddenly didn't feel the need any more to complain or whine, so I reclined a little bit and looked down as he pushed his dick into me. Very quickly my raging lust crushed whatever misgivings I had and allowed me to start enjoying the shafting I was receiving, again. After about thirty seconds of fucking me up my slutty cunt, he pulled out and positioned the tip of his cock against my asshole.
Startled I looked down and whispered, "You're not seriously thinking off putting it back up my aaaaaaaaaaaaaaa... oh my god."
It was too late, he had already shoved it in; I closed my eyes and grunted.
After fucking my ass for about half a minute, he pulled out again and rammed it back up my cunt; he alternated at least six or seven more times, before I had had enough. Not that I didn't enjoy getting fucked in either hole, but his constant switching prevented me from getting off, or even coming anywhere near an orgasm.
With my eyes closed, I made a desperate gesture with both hands and grunted, "Malcolm, will you please make up your mind and pick a hole already!"
"Yes Malcolm," I heard my sister whisper, "Pick a hole and fuck your aunt Erin like the whore she so desperately wants to be."
Startled, I opened my eyes and looked at my sister - fully dressed again - who walked up next to Malcolm, smiling down at me. Although I knew she was around, I hadn't expected her to come in into the room to watch me get fucked. Then again, I did see her get fingered in the hallway too.
