[MF]. My wife’s crazy and curvy sister

This happened July 4th weekend and I have decided that I’m never going to tell my wife. The guilt is getting unbearable but I still don’t regret it and would probably do it again.

My wife’s older sister Bri came to visit us for a long July 4th weekend. She’s 39 and my wife, Becca, and I are both 35. Bri looks very, very similar to my wife. Just two inches shorter and maybe 20 pounds heavier with most of that weight in her booty and thighs.

The first time we met was at my wedding because she lives on the west coast and we are on the east. After the bride and groom dance, we each danced with members of the wedding party and some other relatives. Bri was my last dance before dancing with my wife again.

My dance with Bri turned instantly sexual as she was pretty drunk and had no filter. After some flirty comments, I told her she looked beautiful and thanked her for helping with everything.

Bri danced a little closer, our bodies now pressing together.

“Well you must at least think I’m the prettiest bridesmaid since I look so much like Bri.”

“Definitely” I said. “You look great.”

“I’m like the big booty version of your wife,” Bri laughed.

“Yeah, that’s not a bad thing.”

“Oh, so you like that? Maybe you shoulda married me since I’m apparently your type.”

“You weren’t around so I had to find the next best thing.”

“Wow. You are a bad boy. I’d tell you to put your hand lower but I think everyone is watching us right now. Becca stopped dancing.”

My left hand was creeping down the small of Bri’s back when I looked over at my wife.

“Okay, I gotta go dance with my wife.”

“Probably a good idea for both of us” Bri said with a hug.

So fast forward to three years later. We are all vaccinated and Bri is finally able to visit us and see our new house that we had built. My wife says she is coming July 4th weekend. We picked Bri up at the airport on July 2nd and Bri’s birthday was two days before and my wife got her a present, a small cake, and our favorite wines. We threw Bri a little party after dinner and got into the wines. My wife told me she was gonna go pee and change into PJs and be right down as Bri was off pouring more wine. It was the first time I’d been alone with Bri since the sexually charged but drunken wedding dance.

“So about our dance at the wedding…” Bri almost whispered.

“Oh no. I’m sorry. We were both drunk.”

“Yeah, no, I liked it. I still think about it whenever I see Becca posting photos of you on Facebook. Like, I wonder if this coulda been me if I didn’t move out west. You are clearly doing well and I’m jealous of Becca sometimes.”

“Ah, you can find some rich dude I bet.”

“Believe me I’m trying,” Becca laughed.

“We are doing okay. All our money has gone into this house.”

“This place is amazing. And thank you for the bracelet. I love it.”

“Oh that was all Becca.”

“So you didn’t get me anything for my birthday then?”

“Ah, well I guess I—“

“You can get me birthday spankings since I remember you like my butt” Bri whispered as we heard a door upstairs.

I looked at Bri wide eyed as she laughed and put an index finger to her mouth.

“I can keep a secret you know” Bri whispered.

“That’s really tempting” I whispered back as I heard my wife coming down the stairs. We had a few more drinks and laughs as Bri and I exchanged glances the rest of the night.

Bri announced she was taking a shower and going to bed. She asked Becca if she was showering too and if the water would be fine for both. I said we have a nice big water heater and Becca said she was good a shower in the morning. I noticed Bri looked disappointed.

I started putting glasses in the sink and put the wine away. Everyone said goodnight and got up to go to bed. As my wife was leaving, Bri brought over her glass and whispered “Come see me when she’s in the shower tomorrow.”

I had a whole night to think about this. It took me forever to fall asleep. My wife is never into sex when people are visiting so I didn’t even try. All I could think about was spanking Bri.

The next morning my wife did her usual routine. She ran on the treadmill in the basement and then came upstairs for a shower. I took a quick shower while my wife was in the basement, then got back into bed. I was wearing a t-shirt and my favorite pair of boxer briefs. Becca asked me some questions and I mumbled answers to them and then put a pillow over my head and acted like so was gonna sleep some more. As soon as so heard the shower on and shower door closed, I quickly went to the guest room down the hall and opened Bri’s door.

Bri was laying on the bed in matching purple floral print bra and panties.

“I’ve been waiting for you” Bri said.

“Fuck. You look amazing” I said.

“Do I get my birthday spankings now?”

“Yes”

Bri got on all fours and turned her big hot ass towards me. She wiggled her hips a little. I immediately spanked her pretty hard and felt up her big booty. She moaned when my hand grazed the shiny fabric on her pussy.

I pulled her long hair and spanked her a few more times. She moaned my name.

I sat on the bed and told her to lay across my lap which she did quickly. I spanked her and rubbed her big hot booty. I rubbed her pussy through her panties.

“Fuck. I feel your hard cock on me”

She got up and looked at the bulge in my boxer briefs.

“I don’t think you thought this through. You better get back to bed before your wife sees you walking around the house like that. Just figure out how we are gonna fuck.”

I hurried back just as my wife was finishing her shower. I was jerking my cock until my wife came in the room. I asked if she wanted to hop on but she laughed and declined, saying Bri would hear us.

We talked about plans for today and Becca said Bri and her would be going shopping. I was gonna do some things around the house.

I was in the shed when the girls returned home around 3pm. Bri looked around the shed as my wife and I were talking, looking at my woodworking tools. She commented that it was awesome to have AC out here in the shed. Some friends were coming over and we were gonna watch a neighborhood firework show later that night. So they both had plans to take a nap. I was supposed to run to the liquor store while they were both sleeping and also get charcuterie shit.

Later inside the house, I was about to leave when I see Bri waving her arms at me. I went over to her and she said “Let’s just meet in your shed when I see she’s asleep.”

I waited in the shed and 20 mins later, Bri walks in and starts immediately taking off her tank top and jean shorts. She goes over to me sitting on a stool and I stand up. She drops to her knees and starts to unbuckle my belt. I take my shorts and shirt off and Bri slides my boxer briefs down and takes my growing cock in her hand. She starts licking it and puts it in her mouth after stroking it until I’m really hard. She takes her bra off and I play and grope her tits and nipples as she sucks my cock.

She’s a sloppy and amazing cocksucker whereas my wife is never sloppy despite my coaching. I put her on my workbench and push her panties to the side and lick and eat her pussy. She moans and after a few minutes tells me she wants my cock inside her. I shove my throbbing cock inside her as she sits on the edge of the workbench. We fuck like this until she says she is gonna cum. Bri wraps her legs around me and cums on my cock as I pick her up and start pounding her with her arms and legs around me.

We almost fall and I get her down and bend her over the workbench and fuck her hard from behind until I pull out and shoot a load all over her big hot ass. She wiped the cum off her ass with some shop towels and gave them to me before leaving.

“Let’s get Becca really drunk tonight so we can just fuck in the basement at like 2am” Bri said.

And we did just that. We partied with some friends until 1am and Bri and I kept getting the punch Becca made and pouring it out when people weren’t looking.

Our friends took an Uber home and Becca was hammered and I carried her to bed after she almost passed out on the living room couch.

Bri and I had a beer as we waited to make sure Becca was asleep. Fireworks were still going off in and around the neighborhood and Becca was passed out when I went to check on her.

I went down to the finished room of the basement and see Bri laying topless on the leather couch.

“The leather is cold” she said.

“Well it’s making your nipples look hot af.”

I sucked on her tits while she stroked my cock. Our foreplay could be much longer now and we made out for over five minutes. I sucked and licked her clit for awhile before she finally came. She got me hard again by sucking and jerking my cock. She told me to fuck her face and I did until black mascara ran down her cheeks. Then she rode my cock for awhile and I can’t cum from cowgirl so she rode me fast and hard until she came on my cock. She told me to fuck her as hard as I could and I flipped her on her stomach and spanked her booty before pounding her pussy while pulling her hair.

She wanted me to cum in her mouth so I tapped her on the shoulder and pulled out and she got on her knees. The first shot covered her face and the rest piled up on her tongue before she swallowed.

It was maybe the best sex I’ve ever had. We got to flirt a little more and grope each other but didn’t get to fuck again. Bri is talking about visiting with the whole family at Thanksgiving though.
