It started after I got married. I was the last of my siblings to do so. Two years ago, almost to the day. My brother is three years older than I am and has a wife and two kids. My little sister is 5 years my junior. She got married in 2016, and 3 years ago she and her husband adopted twin babies at birth. I finally got hitched in 2019 at 31 to a 23 year old student/waitress with a fiery personality and a smoking hot body to accompany it. My siblings and their spouses are all attractive, fit people, but my wife Anna is a straight smoke show.
Due to our age difference I was used to they eye rolling and all that but I wasn't expecting it to get any weirder than that. But it did. Much weirder. The first time I noticed was during the reception while I was dancing and drinking and feeling pretty great. My sister, Ariana, was sitting down looking tired or bored or something, so I enthusiastically reached my hand out and gestured towards the dance floor. She forced a smile and followed me to the front by the speakers and I spun her once or twice to a Michael Jackson song before it changed quickly into John Mayers Your Body is a Wonderland. I pulled her closer and we made eye contact.
"Shouldn't you be dancing with your hot college girl to this one?" Ari quipped.
"I'll have a special kind of dance with her later tonight, sis. After I take that dress off! I want to dance with you right now!"
"Sorry my body isn't a wonderland like hers. Since she's almost three years younger than I am. Are you gonna be OK dancing with your old boring sister?"
She seemed genuinely bummed. I was caught off guard. I'd always found Ari very nice to look at. I had actually kind of had a crush on her for years if Im being honest, but obviously kept those thoughts to myself. I tried cheering her up.
"Your body is great, Ari! Jacob is a lucky man to have you. How many housewives have such a squeezable bum? You're still as cute as ever!" I playfully patted my hand on her butt and squeezed gently.
"Easy, big bro. I'm a little old for you to be getting handsy with, aren't I?"
She rolled her eyes in a joking manner, but seemed more serious than she intended. I joked back at her, trying to make her smile.
"You're actually in my prime age zone, sis. It's not your age that matters. Or your body for that matter. In another dimension where you weren't my little sister I may have swept you off your feet with my charm! But I'm glad you're my sister and not just a girl I hooked up with and broke her heart!"
"Shut up, Henry. You don't have to pretend I'm hot to make me feel good. You've always had your type. I'm sure you'll have fun with Miss Double D or whatever you call her."
I don't know if it was the booze or what, but I put my hand behind Ari'so neck and whispered into her ear.
"Last year at mom and dads house I accidentally saw you changing in the bedroom. I only saw you for a couple seconds, but I saw you naked."
I paused briefly and brushed my face against hers as I got closer.
"You have great boobs and I had to fight to look away. I can't believe I'm saying this, but it's so sexy to see a woman with pubic hair, too. I even asked Anna to stop shaving and trim now. Don't sell yourself short. You're a beautiful woman. Just as hot as Anna."
"Oh my god!" she looked me in the eyes, her face blushing deep red. The song was almost over.
"IfJacob doesn't rip this dress off you and go to town until you tap out in exhaustion in the hotel room tonight then find someone who will."
"Congratulactions once again, Henry," she stuttered as I kissed her forehead and let her go as the song changed.
Anna grabbed my hand and pulled me in to dance to an old Lil John song. As she was turned away from me bent over grinding against my partially erect cock I looked over to the table where Ari sat with her family. She was staring back at me. I grabbed Anna's hips and danced as dirty as I could, practically humping her. I saw Jacob take the kids away and Ari get a glass of wine and mingle with other family members. I wondered how much of my boner was due to my wife and how much was from the memory of my sister's naked body and the secret intimate encounter we just shared.
The night tapered down over the next hour, and around midnight I took my bride to our suite on the top floor. She stumbled out of her dress and fell onto the bed, giggling drunkenly. I took my clothes off and pulled her lace panties down and licked and fingered her trimmed pussy for a few minutes until she was just begging me to fuck her. She was a flop, barely reciprocating as I pounded her until she came. She rolled over and I got behind her, guiding my cock between her legs.
"Mmhh," she groaned. "I'm so tired."
Once it became clear she was done and started quietly snoring I gave up. My dick was hard as a rock still as I stood up and looked at my naked wife lying on her back now. The sheet covered her, but I pulled it aside so her bottom half and one breast were exposed. My horny mind acted on its own as I took out my phone and snapped a picture of her. Her legs were spread enough to show her pink inner labia and clit between a neatly trimmed bush. I thought about what I said to Ari earlier.
"Fuck it," I said out loud, as I found my sister in my contact list.
