As everyone left the car Aunt Holly and I hung back a little, and she whispered "that was fucking hot watching you have sex with my sister," in my ear.
"Did you like seeing her cum on my cock?"
"I loved it baby, but it made me a little jealous..." my slutty aunt replied back in a faux-innocent voice. "I could use my nephew's big, hard cock in me again too." Seeing that everyone else was already inside the hotel and out of sight Holly took this opportunity to kiss me hard and press her soft tits into my chest.
"I'd love to Holly, but I'm completely drained - literally. I fucked you, your daughter, and your sister today, I need a little rest before I can go again."
"You fucked Hannah! Jesus Christ that's hot, I wish I saw you guys, could she even take that thing?"
"She took it like a champ and she loved every second of it," I replied smugly.
"Well, she must get that from me," Holly reflected with a devious smile.
"She's definitely a slut like you, she let me strip her completely naked and fuck her outside, anyone could have seen us."
"That's so fucking hot, I want to be there the next time you two fuck."
"Absolutely," I replied, my mind running wild with the possibilities.
"I want you to start slow and sensual, with my daughter's tits pressed against your chest and her tongue in your mouth, but I want you to end it to with you pinning her arms down and fucking her as hard as you can. I want you to fuck my daughter harder than she can take it, I want you to hurt her with your cock. Do you think you can do that for me baby, do you think you can hurt my little girl with your big cock?" I couldn't believe how into this she was.
"There's nothing I'd rather do, especially if you're their to encourage me."
"I'll do more than encourage you baby, I promise you that," she said, slipping her tongue briefly into my mouth again. "But for now, if you aren't going to fuck me I guess I should probably go spend some time with my kids, I can't spend this whole vacation fucking you," she smiled, kissing me again as I grabbed her ass.
"Is that right?" I asked arrogantly, to which she just grinned. "Yeah you go hangout with them for a while I rest a little, then we can have some fun again," I replied.
Holly gave me a devious look, simply said, "Of course, killing two birds with one stone is always a good policy..." and made her way into the hotel.
I stayed where I was so I could watch her ass as she walked away before I went in too, my head filled with images of everything that had happened the past few days.

I awoke alone in bed around 9pm to the sound of my phone buzzing. It was a text from Holly, "wyd?"
"Just woke up, wbu?" I texted back.
"I've been hanging out with Cameron, but he fell asleep while we were watching a movie. You should come over, I miss you xoxo."
I was confused as to why she would want me to come over while she's with her son, and in my post-sleep haze I didn't even think about what she had said earlier, or how turned on she was fucking me with Cameron sitting right in front of us. Still, I got up, threw a shirt and pajama pants on, and walked down the hall to the room Cameron and Hannah shared.
I knocked on the door and a moment later Aunt Holly answered, wearing shorts and a loose fitting t-shirt, through which her big tits were very noticeable, but sadly encased by a bra that was, to no one's surprise, a size or two too small for her. I couldn't really be that surprised that she dressed this slutty even when it just her and her son.
