Your mom has nothing to do around the holidays, so you invite her to come to the holiday themed party you’re throwing with your friends. After she finishes helping you decorate, you two split up to get changed. When she comes to see if you’re ready your sweet mom is wearing…barely anything- with present bows covering her nipples and vagina and a Santa hat labeling her, “naughty”. You are so embarrassed…and secretly shocked and turned on. Your thick mom has no idea why you might not want her wearing that to her party. “It’s on theme sweetheart. Oh jeez, get your mind out of the gutter! I’m your mother, no one thinks of me that way.” Before you can really say anything, guests start arriving and you watch her from the corner of the room as she jiggles about, dancing, greeting your old friends. She was wrong- they are all into it. You’re holding it down the best you can, until they persuade her to be in the twerk competition. Seeing your mom’s ass and pussy shake about in such a seductive way is too much and you have to go back to your room for some alone time. Not one to forget her son, she realizes you are gone. When she barges in because she’s worried she made you upset, she finds you there, stroking your dick and it slllloooowly dawns on her that her outfit is having a super naughty effect on you. She feels awful for not realizing her outfit would garner so much attention and is going to give you a show no one else is getting, so you can get back and enjoy your party without an embarrassing hard on. The bows come off, the oil goes on, and your mom’s insanely big, plump, jiggly parts are right in front of your face. She flirts with you, teases you a little about being bad, “you’re gonna get coal in y our stocking.” She builds up the tension and realizes how much you are totally into her huge ass- and that’s exactly where she wants you to cum. “Don’t worry about the mess, just focus on mommy’s ass. I’ll clean up”. You unload SOOOO much after seeing your mom in a way you never thought you’d see her. Turns out the “Naughty” label on her santa hat was nothing short of absolutely fitting for her.
