Sex with in-laws

It started as fantasy and its technically not my mother in law but my girlfriends mom. We been together 8 years so close enough. All our fantasies we think up are focused on my girlfriend fucking. The things we imagine together are people we know, they are in our social circle, its more intense when its close to home and personal. When her voice is hot and heavy in my ear, when shes grinding on me and telling me she wants to fuck my friends. When shes swallowing my dick and taking short breaks only to ask me if its ok she starts seeing a coworker. Its way more a turn on than fantasizing about a celebrity. 90 percent of the people we have fantasized about, we ended up setting it up. So yeah, my friends, her friends, her coworkers, mine. Her friends boyfriends, her cousin, one of her exs and his friends. There was only 2 fantasies she came up with that was about me fucking another girl. One is our/her good friend and the other is her mom. So to finally get to your questions. My gf initiated the concept or idea. We always had a feeling her mom crushed on me a little. So when we decided to actually go there, my girlfriend suggested I just make a move on her one day when we visiting. She would purposely leave us alone, making up an excuse on why she would be gone for a couple hours, and thats how it happened. I'd love to write a post detailing it one day. We still fuck once in a great while or I get a blowjob.and yes my gf(spouse) has full knowledge.

I always wanted to fuck my mother in law Diane,although she is 70 she still gets my cock hard, I said I would paint her garden wall for her in the summer,I booked a week off work and on the Tuesday I started painting the wall,I had to take my t-shirt off because I was so hot,I only had a pair of shorts on and around lunch time Diane called me in for a drink,the perspiration was pumping out of me and Diane wiped my chest with a towel causing my cock to twitch! Before I knew it I had a raging hardon that was almost touching Diane's leg! Ooohh I'm sorry Richard how embarrassing! For me or you Diane I said? She gave me a confusing look then noticed that my cock was out of my shorts! Oh my Diane said and took a step back! You must have done that to me Diane! She blushed and then I took her hand and put it on my cock! It's your fault I'm like that Diane, she made a sigh as she slowly wanked my cock! A little faster Diane! Arhh yeah she moaned now really getting into a rhythm, she herself only had a pair of shorts on and a loose shirt, I placed my hand on her pussy and she closed her eyes! Oh god yes Richard she said pulling her shorts down! Fuck your pussy is wet Diane, turn around I told her, she leaned forward over the sink and I fucked her

My husband just died at 87. I’m spending some time with my daughter and son in law. They are taking turns to working from home not to leave me alone. I asked him to take a look at my chest for I had a burning rash. In trying to show him the whole rash well I ended up uncovering my breast and he got to see my nipple. I felt a sudden tingle and I liked it. I also have a rash here between my legs, and I pulled up my dress and spread out. He is 58.

So did you fuck him?

We went in a beach vacation with my in-laws where we split a big house. I was 32 and my MIL was 52. We were all on the beach the second day and our young daughter became irritable because she was due a nap. I told my wife I would take her back to the beach house and put her down and would bring her back when she woke up. As we were leaving my MIL said she had enough sun and would head back with us. After finishing with my daughter I didn’t see my MIL anywhere. Thinking she may have changed her mind I grabbed a beer and went to sit in the deck. I heard the outdoor shower below so I peaked over and there she was completely naked in the shower. I had a perfect view and my cock began to grow as I enjoyed the show. As she was rinsing her hair she looked up and saw me. I thought busted! She just smiled and continued. After she finished I could hear her coming up the steps. This is going to be awkward I thought. She came through the door wearing her cover-up. She just walked back to her bedroom without saying a word. After a few minutes she called me and when I went back she was naked again wearing only a big smile. She pulled my trunks down and gave me the best blow job I ever had. I then put her on the bed and ate her like an ice cream cone. We had amazing sex that afternoon and two more times that week. I’ve tried to make advances after we returned home but she said that only vacation sex. I’m hoping we do the same trip next year!

I’ve known my MIL since I was 17, it wasn’t until I was 35, and it was after her 50th birthday party. I was helping her bring stuff back from the catering hall, she was on her 2nd marriage, and I’ve known her to have her fun as well, at least that’s what my wife tells me. But her husband went upstairs to shower and get ready for bed since he had to be up soon, we finished placing everything in the house and stored in the correct locations, she was thanking me and I was flirting as usual.

She said she was gonna go take a shower as well, asked for some pics before she did, then we took some selfies together, that’s when she felt my hard on, and said go home and have my daughter take care of that, I said I’ve been waiting 18 years for you to take care of that, I’m still holding her as she turns around, we just stared into each others eyes, we kiss eventually. She drops to her knees and blow me, I eat her out over the kitchen sink, then bent her over and started from behind before making our way to the couch. We can hear her hubby snoring, we finish, and we’re just laying there, and she says thank you for the birthday present, I haven’t had an orgasm in 4 years.

Everytime we speak about ending it and how it’s so wrong, we just end up having sex. Been 2 years now. We text everyday, and now she’s even sending nudes everyday, 52 and she still looks 32. In 2 months we are finally gonna be alone for a whole week, we have it all planned out already

My 18 yr old wife fucked my father while I was in Vietnam. We'd been married a few months before I was drafted.
A year was too long for her to go without sex, she said! She sent me lots of sexy letters, and 3 packages came with pairs of her bikini panties....always with a couple of her blonde pubes, as requested , stuck in the crotch!
I was the envy of my squad!
My Dad was 42 - very fit, an officer in the Airforce. My wife was apparently a bit of a flirt when visiting my parents and 15 yr old brother.....enough that "your mother took me shopping for a "less revealing bikini" to wear when we all went boating!" The late 60's -- her miniskirts and panty crotch shots and butt cheek shots were quite a bother to my dad and brother she said. "But since it was the style - your mother had to just deal with it!"
She wrote that she was beginning to have sex dreams about doing it with him...."fantasies" would be more accurate I suspect. He & my brother "got a lot of upskirts of my panties" she said, when I came home & she was trying to explain what happened. "They just got too horny I guess!" She discovered my brother was taking her panties....and dad told her what a "sexy little thing" she was. Mom went to visit her very ill mom for a month....and things escalated in the house. Wife in a towel saying goodnight to the boys...nearly bare butt shots. "Up-shorts" in her cut-offs. Then coming down for breakfast "wearing one of your T's, and my little panties. That made them both hard, and they couldn't hide it! Great for my ego!"
So....Stormy night, she slipped into bed with my father. "We made out like crazy! He fingered me, I held his big balls and he asked me to squeeze his dick. Honey, we didn't fuck. He said it was too wrong. So we did 69. him on top of me....usually. We both came. Every night we made out and used our hands and mouth on each other - for nearly 2 weeks! Sorry!...."

I banged my mother in law one night when I picked her up at bar drunk. I got her and to bed when she passed out. I figured fuck it and banged her. She never even stirred. Never told my wife that's for sure.

Never had sex with my mother-in-law but I want to badly. She's in her late 40s recently divorced and is a SSBBW. To be honest she is just an older, slightly heavier version of my wife. The old adage stating that "if you want to see what your wife or girlfriend will look like in the future, just look at her mom" is alive and well in this family. My mother-in-law had my wife at 17, so my mother-in-law is middle aged and I suspect still fertile. She is also very pretty and flirtatious both traits she passed on to her daughter. She always flirts with me and sometimes comes up behind me and rubs her huge fat titts on my back. She always plays it off as it just being a playful joke but I can tell that she wants it. The other day my wife and I were over her house for lunch and I saw my MIL coming out of the bathroom with just her bra and panties on. She stood there in full view for several seconds, turned and slowly walked to her bedroom. As she turned to enter the bedroom door she look back at me, smiled and gave her big ass a extra wiggle as she maneuvered her bulk through the door. My wife saw it as well and just rolled her eyes and said "That's my mom, always on the prowl", then she laughed and walked away doing the same exaggerated hip wiggle as her mother..😆 I don't know where this is going, probably no where, but I would just love to have a threesome with the both of them.

I was 20 and MIL was 42. I came over to help out working in the yard. I stayed for the week helping out. We had hot animal sex for that week. She ended up pregnant. A year later we did it again. My wife had her two babies around the same time. FIL bragged it was him.
