The night was finally winding down at my in-law's house. We were in form out of town, visiting for a few days. Kids were in bed and John, my father-in-law, stayed out at his "buddies" drinking....wouldn't be home tonight. We all knew his "buddies" was really code name for his girlfriend....and so did his wife. My mother-in-law, Mindy, knew all about his exploits and had long given up on caring. She is big woman, 5 ft 7, around 260 lbs I would guess. Shoulder length blond / gray hair, an apple shaped body with big tits. Her size and lazy un-happiness about it had led her to pull away from her husband, quietly blaming herself for his cheating. I suspected she had long given up on sex.
But her curves were well rounded, almost like a sculpture, rather than rolls of fat. Mindy's skin was beautiful, keeping her looking younger than her 53 yrs of age. Now, I'm an ass man. Her ass was large, round, and seemed to flatten for a couple of inches at the height of her mounded buns. Like a large breast with a flat end rather than a nipple. Definitely not an ideal ass, but I always had a devious curiosity to know what it would be like to fuck a larger woman like her. And she certainly had a good shape that you would watch jiggle around if she had a dick slamming her from behind.
She has a friendly personality, but always intense and stressed out. Definitely loving and generous with her family. My wife and her mother could not be more total opposites. My wife, in her late twenties, has a small frame, 5 ft 5. Her upper body slightly longer than the bottom. Slender legs with muscular calves. 36c breasts with tall nipples when aroused. And an ass that I enjoy fucking the hell out of .
The one thing they do have in common is great skin. The Scandinavian blood adding just a little texture and color. Beautiful. And so soft. Since it was getting late and Mindy was planning to stay up for a while, she disappeared for a few minutes and came back down in her night gown. A green, silky gown with a low cut front, revealing a 1/3 of her cleavage. The length ran to about 2/3 of the way down her thighs. Her legs were visible just a couple of inches about the knees. Her legs were not large as I had imagined, but thick. I took a double take when I saw her, realizing my peering was a bit obvious. I glanced up at Mindy and she was looking right into my eyes, with a smirk, and quickly looked away. My cock stirred as I let my imagination wonder for a moment, contemplating what it might be like to fuck her in the ass, slapping it hard....making her take it. The thought of that pleasure and control sent a tingle through me.
My wife winked at me as she headed down the hall-way, wiggling her little as dramatically enough to make eye-contact with me and shoot a devious smile. I knew what that meant and didn't hesitate a moment. Her mother, now sitting at her computer on the other side of the room, watched our little interaction take place. She just smiled. "Good night you two."
My wife & I turned in and retired to the down-stairs bedroom, leaving my mother-in-law to stay up a little later, finishing up a work project on her computer. I closed the door behind me and playfully chased my wife down the short flight of stairs, into the basement. I'm not sure what had gotten into her, but that night my wife was a real animal. She is normally a little sexually suppressed when we are at her folk's house....reluctant to really get into the mood. This would limit us to quickies when visiting her folk's house. But that night she was insatiable. She sucked my dick, commanded me to fuck her ass and then followed it up fucking me on top, reverse cow girl style. My wife is a vocal love maker and had a hell of a time not drawing attention to what we were doing downstairs. But she did great.
I awoke about an hour later in need of a glass of water. I checked to see if there was any light coming in from under the door. I was still naked and really didn't want to get dressed. I would just make a mad 15 ft dash, there and back. I slowly opened the door and peeked out. Though I couldn't see it before the door was open, a dim soft light landed on me and I took a step back. Peering out the crack in the door, I saw my mother-in-law still sitting at her computer, the soft light from her small lamp the only light on in the house....except her computer monitor.
My eyes began to focus a bit better and I was debating how quickly or quietly I could make it to the kitchen sink, which was directly in-between us, about 10 feet away. I reasoned that it was tall enough that from where Mindy was sitting, she would not be able to see below my stomach. I was starting to get chilly standing there and still thirsty as hell. So I decided to do it. I didn't walk too quietly, just enough that I wouldn't startle Mindy. She moved her chair a little when she heard me. Her back was to me, her head blocking any view of the monitor. I heard her click the mouse a few times as I shuffled over to the sink. Grabbing a glass out of the cupboard next to the sink, I watched as she turned to face me, her computer displaying only the desktop.
She seemed surprised just for a second that I didn't have a shirt on, then the look passed.
"Can't sleep?" she asked?
"Just getting a drink." I said.
She slyly smiled and said, "I figured that work-out you two had down-stairs would have knocked you out by now."
My face must have turned red as I tried not to smile.
"Don't worry about it. I'm just teasing you. You two can do whatever you want down there. We're all adults here."
"Fair enough," I said, "it's cool that you're not stuffy about it." I filled up my glass.
"Not at all," she said, swinging back toward to her computer and turning off the monitor. "I finished my work a while ago and was just surfing around, waiting for you two love birds to quiet down before turning in."
She swung back around, stood up and stretched. As she did, her night gown slipped from just below her panties to her knees. I hadn't realized that her gown was up. Was she playing with herself while looking at porn, I wondered?
Suddenly I remembered I was naked as she began to walk towards me. I didn't know what to do, there was no way she wouldn't see me now...I hadn't left the room quickly enough. So, I impulsively just slowly picked up my glass and acted like it was no big deal. As she approached the counter, my full naked body came into her view. The room was dimly lit and I could not see her face as well as she came closer, it was darker on this side of the room.
But I could see her eyes travel down my body as she got closer. Our eyes met after she looked me over. She had a big grin on her face. She stood right in front of me, placed her hand on my shoulder and kissed me on the cheek. She quickly gave my butt as small pat and said "nice" as she walked down the hall to her bedroom.
"Goodnight" she said, her back to me as she walked.
I was stunned. Was she flirting with me? I mean, we would joke around about sexual stuff on rare occasion, but never any blatant flirting.
I watched the darkness swallow her as she got to her room. She flicked the light on, illuminating the hallway and stepped inside, leaving the door just slightly open.
