I had planned to finish my meetings early to return home and join Phil and Autumn. However, it ended up being a few hours longer than anticipated. I had expected Autumn to have worn out Phil by that point in the evening, but I had underestimated the effect a busty, gorgeous 19-year-old niece might have on her uncle.
"Hi Autumn! I'm back," I called out from the doorway, but no one answered. I glanced at the clock; it was still 5 pm. The Boys would be returning in a few hours, I noted to myself.
'Maybe she left to meet some friends,' I thought as I made my way up the stairs to my room. However, the sounds coming from my bedroom quickly told me otherwise.
I smiled to myself as I opened the door and was greeted with quite a sight. My daughter was on all fours, her tits bouncing wildly while Phil pounded into her pussy like crazy from behind!
"Ahhhh...ohhh...ohhh...fuck me! Uncle Phil! Don't stop! Keep fucking me!"
They were both so lost in lust and pleasure that they didn't even realise that I had entered the room.
"Autumn...oh God..." I heard Phil groan. "This has to be the best sex of my life! You are such a sexy little slut.... Ahhh fuck... I can't believe my nerdy little niece can make me cum so much. Ahhh yessss... fuck, that feels so fucking gooood..."
Autumn however was completely gone and unable to reply, moaning in pleasure loudly and pushing against every thrust by her uncle, "Fuck! Ahhhh... fuck... faster!!... ahhh yess...yesss!...ohhhh yeaahh fuck me!"
I didn't want to disturb them as I dropped my jacket on the table and began taking out my earrings, acting all casual, as if the fact that my brother-in-law was fucking my daughter in my bed was the most natural thing in the world.
Once I was done, I smirked and walked over, surprising Phil with a poke on the shoulder. "I can't believe the two of you have been going at it since this afternoon. Are you trying to break my daughter, Phil?"
Autumn's neck craned back, but her body stayed locked in place; Phil's cock thrusting in and out of my little girl, her breasts swinging back and forth, "Mmm... M-mom!...ohhhh fuck!... you're h-home!"
"Yes, mi amor. You both seem to be having such a good time. How many times did he cum?" I teased them playfully.
"Well actually, I took out Autumn for some lunch. Then we went shopping. I bought her a few sexy things, and then came back to fuck some more!" He explained, still hammering away at my daughter's tight little pussy. "I made her cum twice after you left, but she is being such a horny slut! She just wouldn't give me a break..."
As if to emphasis this, Autumn moaned in pleasure, "Oohh...fuck me, Uncle... I just want your cum deep in me." She gave Phil an innocent little pout, "Don't act as if you didn't want me riding that big, hard, fucking dick of yours...Oohh...Fuckkk...!"
"Mmmm..." I purred, "Sounds like you two have had quite the day... I wish I could have stayed with you!" I replied, leaning in to give Phil a deep passionate kiss. "Can I join in on the fun too?" I asked, licking my lips, "I need some of your big cock in me as well!"
"Ohhhh... I'd love to Isis... but your daughter's milked me two times already... I'm getting really...really close... to cumming!" He replied, breathing heavily. "I'm not sure I can go another round... even for you!"
I bit my lower lip, visibly disappointed, but I didn't want to ruin their moment. "Well, my sons will be back home soon, so you better cum fast!" I told him as I walked into my bathroom to take a nice relaxing shower.

I came out half an hour later, wrapping my satin robe around me, to find that Phil had finally left. Autumn lay on the bed, completely naked, with a satisfied smile on her face.
"So did you two have fun?" I asked her, taking a seat beside her and caressing my fingers through her long dark hair. Her eyes closed in pleasure, and she smiled up at me with a nod. "He fucked my brains out, Mom! I can't believe sex feels so good!"
"Oh, mi Amor! There's much more I have to show you..." I replied with a devilish wink, "But I'm still surprised at how the family's 'Good Girl' like you ended up being so naughty!"
"I guess I am just like my mom, a complete slut!" She whispered with a small chuckle.
We both grinned and laughed as she told me about everything that she and Phil did that afternoon. From shopping for lingerie and some new clothes, to eating out, to going back to the house, and fucking each other's brains out again and again.
We continued chatting until the sound of the main door closing indicated that my boys were finally back home. Autumn quickly jumped up and got dressed before heading out of my room. She gave me a wink as she left.
As I watched her sexy little ass bounce out of the room, little did I know that this little incident would spark something far more naughty in my household in the weeks to come.

An hour later, I was alone in the kitchen preparing dinner for the family. However, now that I had a moment to think about it, Phil's refusal to go one more round with me stung a little.
I never had that problem with my son's. Those boys could go on and on for hours. I pouted as I cut the carrots and thought who needed Phil when I had such amazing studs living right here in my own house! This seemed to cheer me up. Hopefully, Autumn was all tired out from her antics of the day and me and boys might be able to get some alone time for a quick fuck tonight.
Then, as if on cue, I heard two pairs of heavy footsteps stomping down the staircase. I smiled as the boys walked into the kitchen, their eyes lighting up with mischief as their eyes scanned over their barely covered busty MILF of a mom.
I had purposely worn something extra slutty tonight. Afterall, I didn't need to worry about Autumn's judgemental looks anymore. Not after what she had been up to all day. I wore a crop top that clung to my large firm 36D breasts, stretching over my nipples, but exposing a generous portion of under-boob, as well as, my midriff. My booty shorts hugged my ass cheeks, letting them peek out a little from below.
I could tell that my boys appreciated it, from their lust filled gazes to their cocks tenting a little in their shorts, which they made no attempts of hiding from me.
"Hey boys... Mom missed you today!" I teased as I turned around to face them, biting my lower lip. I could feel their hungry gaze roving up and down my body.
"Damn, Mom! You look smoking hot!" Ryan groaned.
I bit my lip at his words, my fingers reaching up to pull down my crop-top to expose more of my cleavage to them both, teasing them, "Really mi amore? You like my new outfit?"
