We all took quick showers, separately, unfortunately, but whatever. This plan required a lot of sex on my part so it was probably better I didn't get worn out beforehand.
We all sat on the couch in our costumes as Trinity explained her ploy. The plan started out complicated but then Aunt Kim and Sara started making out as I watched and whatever Trin was saying was kind of lost. I took my cock out of my pants as they started taking their clothes off, slowly jerking it as I watched my aunt and cousin play with each other's tits and pussies as they made out right next to me.
Trin just watched me, a lustful haze taking over her face as she forgot what she was saying about a plan. She tore her eyes away from my huge cock as she glared at Sara and Kim angrilly, "Why the hell are you two so horny for each other all of a sudden?" She asked and then, even more angry, she said, "You two are mother and daughter and I'm watching you fingerbang!"
Sara stopped kissing her mother for a moment, though she kept playing with Kim's pussy I noticed. "Whatever Trin, you just got done fucking your own brother. I think that's way worse."
"Oh yes dear, like that," Aunt Kim moaned as her daughter fingerbanged her tight pussy, but then, in a normal tone, "And Sara and I have always been open about sex and we're both bisexaul." Kim explained, "It just makes sense that we fuck each other to satisfy our naughty cravings."
"Says you Mom," Sara said, "You only get fucked once a year! I like fucking around."
"Well, that stops now," Kim said as she put a hand on Sara's beautiful head and started pushing her down to her pussy, "From now on, if you feel horny, my slutty daughter, you come to mommy."
"Okay Mom, I'll Gwack!" Sara tried to keep talking but at that point Aunt Kim had pushed her down on the couch enough that she could push Sara's face into her sopping wet pussy. Sara, like a good daughter, started licking away at her mother's pretty snatch.
"Oh man," I said, "This is so fucking hot! I Need to fuck you right now!" I stood up and lined my cock up with Sara's hot pussy which was sticking up in the air on the couch as her mother had her in the doggy position as Sara ate her mother's cunt.
"NO STOP!" My sister shouted and we all stopped what we were doing to look at Trinity standing next to us. I think we were all wondering if she'd come to her senses about how "incest was wrong" and all that. But then she said, "I want Fred to fuck me. I'll lick your pussy instead Sara."
"Oh, I thought you were too good for that." Sara said, but then her mother grabbed her and forced her to lick her pussy once again.
