It made me want to jack off again but decided to hold for my pretty sister-in-law in hopes she would not get flooded with guilt and would come to see me again that night.
Josie had told her mother about taking a weekend and leaving me with the kids. Her mother invited us over for dinner. While Grandpa played with the kids Emily and I worked on the dishes. The girl’s mom was pretty, not very tall and thin and for the first time, she seemed to be acting a little flirty. We had a little body contact while standing before the sink.
“You know, the girls are lucky they got their figures from their Dad’s side rather than me.”
Emily seemed to be fishing for a compliment. I don’t know what gear my brain was in.
“I don’t know about that. You’re a pretty neat little package.”
Did I say that? Fuck! Emily smiled at me.
“I’m just somebody’s mom. My ass is boyish and my chest is almost non-existent. No man ever gives me a second look.”
My mother-in-law paused, then giggled.
“You think I’m a neat little package?”
She giggled again and moved a little closer. I nodded and grinned.
“Thank you. You’re sweet. That makes me feel good.”
She leaned in for an “I’m your wife’s mother” gratitude kiss. It was probably meant for my cheek, but our lips met for an instant. We looked into each other’s eyes for a couple of seconds then kissed again. This time Emily used her tongue. I met it with mine. She hugged me around the waist as the kiss continued. My boner leaped into hardness against her tummy.
“Oh, my God. You’re for real serious, aren’t you?” Her eyes and mouth are both wide open. “Oh, damn. How big is that thing?” She whispered.
Much like her younger daughter, Josie, she was impressed by my just slightly above-average size. She didn’t reach for it, just let it press against her as we went back into kissing. I grabbed her ass. It was firm and slightly more than boyish. I started wondering what her pussy must look like as the kiss continued until a very flustered forty-year-old started looking around as if to find a place for us to fuck on the spot.
I was equally ready, not only from lust but from the fact of a possible family triple play.
The sounds of the kids playing with Grandpa got louder like they were starting up the stairs from the basement family room.
My mother-in-law whispered: “I’ll suggest keeping the kids overnight. Herb plays golf in the morning.”
Suddenly the kitchen was full of noise.
“We’ve come up for some of that cake I saw earlier.” Herb chuckled as he continued to play with the grandkids.
Unnoticed, but a visibly shaken Emily served the cake and poured soda from a two-liter bottle. I was struggling with getting my hard-on under control as I watched her body movements under her clothing. Wanting to see Emily naked wasn’t helping with the hard-on at all.
The suggestion of keeping the kids overnight was made and soon Grandpa and Grandkids were back downstairs laughing and carrying on again.
Meanwhile, after watching Emily give me a very horny and adventurous look we were kissing. Pretty much out of control was begging.
“Maybe just quickly put in the tip.” She gasped. “Just to prove we are going to do it.”
We were both wearing shorts, so I pulled mine down and Emily stepped out of hers.
“If they come up I’ll run into the bathroom”
This little dream woman scooted back on the table still with dirty dishes from the cake and spread her legs open revealing a very tight-looking, surprisingly shaved cunt.
“God, that thing is huge! Just the tip!” She coaxed.
I moved in between her spread-open thighs. She was wet, a little of her girl juices dripped from the bottom of her slit. Emily lunged as soon as the head of my cock made contact. Her outer lips opened, but couldn’t take me inside. Damn, my cock was huge to her, much like with her daughter Josie.
We must have been a curious sight with me trying to get my cock inside my mother-in-law while her husband and my kids played downstairs. Emily was freaking out, wanting me inside her tight twat. After a couple of more strokes, her inner lips yielded allowing passage for the full head to slide into her cunt.
Emily was propped up on her elbows, looking at where my shaft entered her cunt.
“Wow! You’re in me! I thought you’d rip me apart. It hurt a little, but you feel amazing inside of me.” She hissed.
I had done it. I was fucking my cute mother-in-law. The boyish ass and lack of tits did not affect how good her cunt felt gripping around the head of my cock.
“There you go, Emily,” I smiled. “Just the head!”
She looked towards the sounds of playing from the basement.
“Maybe we have a little more time.” She did this cute little thing biting her lower lip.
I nudged into her much to her appreciation. Her facial expressions were probably meant to accompany screams of pleasure as our unholy mating together began. Meaning she was enjoying me fucking her, intensified by her husband and my kids just down the stairs.
After a couple of minutes, she looked at me in surprise.
“Your balls are up against my ass.”
“Yes, balls deep. My whole cock is inside you. It didn’t rip you open after all.” I teased.
“Oh, God. Quite the opposite. Fuck me harder!”
“Can you be quiet?”
“I promise. Damn it, fuck me!”
It was all too much. A short time later.
“I’m about to lose it,” I grunted.
“Cum in me! Do it!”
I drained my balls into my wife’s pretty mother. She orgasmed hard when she felt my cum spurt for her cervix.”
“Oh, my God! You are so fucking deep inside me!”
We quickly rearranged our clothing with Emily getting in her shorts and panties. She gave me a quick kiss.
“I’m going to keep your seed inside me. It will probably take a week to come out from where you put it anyway.”
“Keeping a little memento are we?”
“You bet, and it’s a good memento. Warm and squishy inside me.”
Her eyes went to the crotch of my shorts.
“Oh, my God! You’re still hard!”
She looked towards the basement stairs.
“Can you cum again?”
“I don’t know. With you, probably. No promises.”
“Oh, Jesus!”
My mother-in-law’s shorts and panties came off again and she turned towards the table.
“I want to do it from behind. My husband won’t do it. He says it’s nasty and unnatural. I feel like being nasty and unnatural!”
With her bent over the table, her little cunt was wet with our juices and open. My cock went full depth went full depth on the first push. I could feel a little more of her give way.
“Oh, fuck! That’s deep. You keep finding new places to go inside me!”
The sounds of wrestling and children giggling continued from the basement. I pumped my children’s grandmother for all I was worth. The sounds of playing downstairs continued as we fucked for several minutes, neither one of us wanting it to end.
My balls were slapping wildly against Emily’s ass when she began to lose it.
“Oh, there, yes, right there. Oh, fuck me. I need your cum inside me again.”
That sent my testicles to churning and another load of seed rushed up my length.
“Oh, God! I feel that.”
She began bucking back against me, shaking the table, as she let herself cum again with me.
