I always had this strange feeling that my mother in law thought I was attractive. I knew she was happy that I married her daughter. We were always friendly but never flirty or anything like that.

I also knew she had a wild side in the past. After her divorce there were rumors she had wild threesomes, drank a lot, and was a fan of smoking pot.

I should mention she lives down the street from my wife and I. So it’s not abnormal for us or her to pop over to each others houses unannounced.

It was a summer evening a few years ago that I decided to pop over unannounced. My wife was out of town visiting her sister who had just had a baby and my kids were having an overnight at my parents house. I was bored and had taken a few marijuana gummies a little while before. Needless to say I was high as a kite.

I walked over to my mother in laws house. Her boyfriend was away for the night on a fishing trip with some friends. She invited me in and we sat down at the kitchen table and started chatting. It was nothing out of the ordinary just small talk how are things going, talking about her new grandson, my wife, life in general. She pulled out a joint and we went on the back porch and smoked it.

We came back inside and continued to chat. After a few minutes we were both feeling pretty fucked up and frankly I was getting really horny. That happens sometimes when I get high.

My mother in law, Jennifer, is not normally my type. For instance my wife is 5’4” 155 pounds, average size boobs, great ass.

Jennifer is around the same hieght maybe an inch taller, huge tits, and if I had to guess probably 250-270 pounds.

Anyway out of the blue because I’m feeling horny and frankly was high as balls I say to her, “I know this is kinda random but have you ever thought about the cock your daughter (my wife) gets.”

We both start laughing and then she says, “Actually, yeah. I’ve always wondered how big you were. Mandy has never said anything about it, but when you guys were dating and she still lived here I heard you guys fucking on more than one occasion.”

At this point I felt a little twitch in my pants and decided it was now or never. I said “It’s just us here, so what the hell just don’t tell Mandy.”

I got up from the table and pulled out my cock and I saw her eyes light up.

“Oh wow that’s a nice dick!” She proceeds to put her hand around it and start jerking me off.

“Nice and thick too. This is much bigger than Ron’s.” Ron is her current boyfriend.

Next thing I know we’re heading to her bedroom. She tells me to lay down. Proceeds to take her top off springing out those big fat milf titties. Pulls her pants off and climbs up into the bed and starts sucking my big hard cock.

You can tell she’s sucked a lot of dick in her day because it was arguably the best head I’ve ever had. My wife hardly ever gives me head so I knew with how good she was going I might not last too long. 2 or 3 minutes later I tell her I’m gonna cum and she just deepthroats it all the way and I shoot loads down her throat. She swallows all of it.

I then tell her to lay on the edge of the bed. I slide her soaked panties off. She had what I can only describe as a milf bush. Mid 50s year old woman with a thick full bush. I didn’t even care I made a diamond with my hands spread her lips and started licking that clit.

“Oooohhhh ahhhh that feels sooooo gooood. Don’t stop. Right there” she moaned.

After a few minutes her legs were quivering and she was begging me to fuck her.

I stood up stuck my hard cock in and railed her missionary for what felt like forever, but in reality was probably like 5 minutes. Then I had her flip over and started smacking that ass and pulling her hair while fucking in doggy.

I asked her where she wanted me to cum and she said inside her. After that I couldn’t hold it anymore and I just blasted spurts of hot jizz inside her.

I slept over that night and we fucked again in the morning before I went home. We agreed to never tell her daughter or speak about it again as she doesn’t want to ruin our marriage.

To this day that’s the only time I’ve ever cheated. Still happily married to Mandy with 5 kids.
