Showing up at her friend Tracy's birthday party in perfect attire.

"I can't believe you're actually going through with this, mom." Greg groaned.

"Yeah mom, I mean like... Everyone you know is gonna be there, and you're totally fine with just showing them everything?" Tommy added.

"Relax, you two. Everyone's gonna love it! I'll be the talk of the town!" Joan rebutted

"Yeah... That's what we're afraid of."

Joan pressed her bare foot down on the brake pedal and pulled into park. Stepping out of the car completely naked, having not dressed a stitch since yesterday morning. The cool Sunday night breeze enveloped her voluptuous body.

"Oooh... I can really feel that in my Vag, so glad i decided to go nude."

"Mom... Please don't talk about your... Vag."

*Ding Dong* *crrreeeak*

"Joan! So glad you could... OH MY GOD! WHY ARE YOU NAKED?!"

"Happy Birthday Tracy! I hope you don't mind but considering the occasion, I thought it'd only be appropriate if i showed up in my Birthday suit~" Joan announced as she slipped through the front door, posing with her arms behind her head and taking a wide stance while gyrating her hips, as if she was trying to expose as much of her body as possible.

Needless to say, the ambient chatter fell to an icy silence as they stared down the Naked MILF.

"*snort* mph-thf-HAHAHAHAHAHA! Oh. My. God. Joan! I love it!" Tracy exclaimed in a fit of laughter. Pulling Joan in for a tight hug, Tracy treated herself to grabbing a handful of Joan's giant jiggly ass. The party-goers quickly joined in the raucous giggling.

"Ooh. *Snap* Greggy! Gimme the gift. This is for you. For those nights when Frank's working overtime. I know my own's helped me through many, many lonely evenings... Just wait until you're alone to open it..." Joan handed Tracy her gift, wrapped in a narrow, foot-long box.

"Thank you sooo much Joan, I'll be sure to think of you whenever i use it~" Tracy responded, pulling Joan in for another hug. This time pressing her crotch as much as she could into Joan's bush and grabbing her bare ass with both hands, spreading Joan's cheeks to a crowd of "oohs" and "aahs" as they ogled her butthole. Letting go, causing the two meaty mounds to clap together loudly. And finishing off with an encore of a short drum solo of slapping upon Joan's crowd pleasing booty. Tracy even followed up with a quick kiss before putting her arm around her naked best friend's shoulder, the two walking off, deeper into the party.

Meanwhile, The Twins could only stare in shock at what they had just witnessed, before being joined by some of their friends from school.

"Dudes. Your mom rocks!"

"Yeah, you don't mind if we take some pics, right?"

"Oh! And video! I already got a recording of her whole entrance."

"Dude you gotta send that to me! I only got this one close-up of her butthole. Your mom has a great butthole, dudes."

"Already did bro, sent it to everyone in school. Make sure to send everyone that butthole pic too."

"Please... Stop talking about our mom like that..." Greg, once again, groaned.
