After my mother in law, Anita, caught me naked in the kitchen, she'd spanked me and made me jerk off for her while my wife slept unawares down the hall.
Just as I had cum all over the floor in front of her, my wife arose and came out of the bedroom. Anita closed her robe. Retreating, she'd smiled at me. "Think about me when you jerk off," she'd said wickedly, before leaving me naked in the kitchen again.
While my wife was in the bathroom, I'd thrown on my running clothes and just made it out of the door.
In the eight years that I'd known Anita, she'd never shown me this side of her. Remembering how she'd opened her robe completely, allowing me to gorge on her hot, mature, naked body while I stroked for her...my cock swelled in my shorts, bouncing in front of me as I ran.
I couldn't get her out of my head.
Her body was exciting. Her breasts were much larger than my wife's. I thought again about the thick, dark bush between her thighs.
Swelling to full erection in my shorts as I ran, I pictured again the way she'd looked at me...so naughty.
"Call me mama," she'd said as I'd masturbated naked in the kitchen while she watched. The feelings I'd experienced were insane...I'd been scared to death that my wife would catch us at any moment...but...I'd also been so excited that I could barely breathe.
I ran farther than usual that morning, needing to wait until my erection was under control before returning home.
Finally, I reached the end of my street and slowed, walking the rest of the way to cool down, attempting the gargantuan task of pushing my mother in law and what had happened that morning from my mind.
As I entered the living room, I peeked around the corner to the kitchen. My wife, Karina and her mother sat at the table, chatting over their morning coffee in their robes.
"Hi honey," my wife greeted me, "have a nice run?"
Her mother, Anita, grinned at me, catching me off guard.
"Uh," I started, then, "yes...yes I did." I recovered quickly.
Facing me from across the table, I saw Anita spread her legs beneath it. Her robe parted.
I swallowed hard.
My cock twitched as I stared.
"breakfast darling?"
"Huh?" I said, jerking back to reality.
"Would you like some breakfast darling?" my wife said again with a smile.
"I...I uh, I mean, okay. I'm gonna take a shower first," I said, hurrying by before my cock formed a tent in my shorts.
"Okay," my wife said, sounding a bit puzzled as I rushed down the hall.
Once in the bathroom, I stripped and started the water. When it was hot, I stepped under it and closed the shower door.
My cock pounded and throbbed.
Taking it in hand, I closed my eyes and re-imagined my mother in law standing in front of me, totally naked. I saw her large, bare breasts capped by her dark, thick, excited nipples. In my imagination, we were in the kitchen again. I was totally nude in front of her, stroking for her while she fingered herself...slapping and playing at her swollen clitoris.
"Oh Hijo," I heard her say, "stroke it for me...stroke it for Mama..."
With my eyes closed under the shower, I pounded myself, pulling and twisting on my throbbing erection to the mental images of my mother in law.
"Babe?"
My wife's voice reached my ears, shocking me out of my fantasy.
"Babe, what are you doing?'
Suddenly, the shower door opened.
"Wow," she giggled, as I stood there, embarrassed, erection in hand.
"Your run really turned you one huh?"
"I...well..." I stammered.
Karina and I sometimes masturbate for each other, but I was embarrassed at being caught fantasizing about her mother. I knew she didn't know it...but still...I felt awkward and guilty at what I had been doing.
"I think I want me some of that," my wife smiled. Eyeing my erection, she slipped off her robe and stepped under the water with me.
Taking my cock in her dainty hand, she stroked it, before clamping her mouth over mine and pushing her tongue between my lips.
Her pert little breasts pressed into my skin as her nipples hardened into it.
Horny as hell from fantasizing about her mother, I grabbed her. Spinning her around quickly, I bent her over in front of me.
"Woa!" she giggled, placing her hands on the shower wall for support.
Spreading her legs with mine, I guided my throbbing erection to the entrance of her folds. She was already wet.
With a thrust, I entered her, sliding my cock full-long into her as she moaned, swallowing me whole with her tight, wet box.
"Yah fuck me..." she said, pushing back, fucking herself onto my cock. With one hand, she reached between her thighs and rubbed herself while I pounded her hard from behind.
Only, in my mind, it wasn't her I was pounding.
My wife's dark skin matched the color of her mother's. From behind, it was easy for me to imagine that it was my mother law, bent over naked in front of me.
Sliding my hands underneath my wife's taught body, I cupped her tight breasts, kneading her them, pinching and twisting her stiff nipples between my fingers...imaging that it was my mother in law's big, pendulous tits that I was feeling.
I imagined the weight of them and how they felt in my palms.
"Fuck me Hijo," I heard her say in my mind as I thrust deep and hard into my wife, pounding her little pussy for all I was worth.
As my wife moaned hard, she rubbed herself faster, pulling and pinching at her clitoris as my cock entered her, rammed her to the hilt, pulled back and repeated the pattern over again, growing steadily faster.
"Fuck me Hijo," I imagined my mother in law's voice filling the shower. "Fuck me harder...fuck Mama..."
"Oh god..." I moaned aloud, as my orgasm built in my belly.
As my wife turned her ecstasy-twisted face over her shoulder to look at me, I saw her mother's, grinning wickedly at me.
"You like my big tetas son?" she said. "Fuck it, fuck that pussy...yah... cogerme...follar mi coño!"
The idea of my mother in law telling me to fuck her cunt was too much.
I came, hard...jettisoning thick, hot ropes of cum deep into my wife's hot pussy as she fingered herself to orgasm. Moaning loudly, she thrust onto me, cumming all over my cock.
"Oh god mama..." I breathed aloud, slamming myself into my wife, cumming, filling her with my seed.
"Sí! Dios papi...oh god, I'm cumming..." my wife matched my moans. Squeezing her cunt muscles hard, she wrapped my spasming cock with it, riding the waves of her own orgasm.
Finally, when we were finished, my wife stood as I slipped from her.
Pressing her lips on mine, she kissed me deeply.
"You've never called me Mama before," she giggled, searching my eyes as I flushed deep, feeling my face hot with embarrassment and a tinge of fear.
I hadn't meant to do that out loud.
"I'll fix breakfast," she said, rinsing off. Then stepping from the shower, she smiled at me.
"Mama..." she grinned. "That's so hot."
I smiled back but inside I felt ashamed. Grabbing the soap, I tried to wash it away as my wife wrapped her robe around her and disappeared through the door.
After my shower, I dressed in the bedroom, wondering at the mix of feelings inside me.
I'd just had sex with my wife, imagining that I was fucking her mother. That morning, I'd masturbated, totally naked in front of Anita while she spanked me.
It was all too much.
I worried that my wife would somehow discover what I'd done.
Although I felt pretty certain that Anita wouldn't say anything...still...she had threatened it that morning. She's threatened to tell her daughter that I had exposed myself to her if I didn't do as she wanted.
I'd allowed myself to get carried away with lust and excitement...but now...I wasn't sure. At first, I'd thought maybe it was a one-time thing; it would be a secret between my wife's mother and I that I would take to my grave.
But after she'd spread her legs under the kitchen table at me, I wondered, and I worried.
Thankfully, the rest of that day passed without any further incidents between my mother in law and me. Anita behaved as if nothing was out of place, and I began to relax around her. The following day was the same.
By the third day after what had happened in the kitchen, I began to think that maybe I had been right. It had been a one-time thing. Anita had gotten her excitement, as had I, and now I could just chalk it up to a hot memory and get on with things.
I was wrong.
Three days later, on a beautiful, warm afternoon, my wife decided that it would be a perfect day for a family picnic. After packing some sandwiches and drinks into our picnic basket, we loaded it along with some blankets to sit on into the trunk of the car.
Anita had dressed in a light, yellow summer dress for the picnic, while my wife wore shorts and a tank top, while I had chosen a pair of summer shorts and light collared shirt.
As we prepared to climb in, I opened the doors for the ladies.
"You sit in front Mama," Karina said, indicating that her mother should take the passenger's seat while she sat in the back.
This wasn't unusual as my wife normally offers for her mother to sit in front whenever we drive together.
Once we were seated, I dropped the car in gear and pointed it towards the park by the lake, several miles away.
