Adrienne squirmed, writhed and moaned on top of the bed as I continued my assault on her wet cunt. My mouth was fully covering her pussy, my tongue focused on her clit as I drove her closer to her second orgasm of the day.
She worked her hands through my hair, screaming loudly as I continued to tongue-fuck my sister in law. Her sweat and her arousal gave the air a sweet, musky smell and I had to use one of my hands to adjust my hardening cock to allow for the movement that Adrienne's screams were causing.
It had been about a week and a half since our first encounter on the couch of the living room, and ever since that night there had been a lot of flirting, teasing and downright debaucherously dangerous activity in the house. It could be as simple as a flick of a tongue across lips, a simple gaze downward, and once, when Adrienne had been inexplicably bold, a flash of her tits while my wife was facing the other way. On another occasion after Adrienne had bid the household goodnight, she winked at me suggestively. After putting our daughter to bed at the other end of the house, I crept back down the hall so as not to wake everyone, when I saw the door to Adrienne's bedroom ajar, with a dim glow coming from within. I could hear a faint, yet familiar noise coming from the doorway, and couldn't resist the urge to take a peek on my way past.
I was rewarded with a very pleasant sight. Adrienne, gloriously naked, on her back on her bed, knees up, legs apart, with one hand furiously rubbing her clit while the other worked her pink vibrator in and out of her wet snatch. If that wasn't enough of a turn on, she was staring straight at me, straight through the door, her moaning no more than a whisper. She mouthed the words "I want your cock" as she thrust the vibrator in as deep as she could, and I stood in the doorway and placed my hand on my groin, squeezing and stroking myself through my pants. I watched her gaze lower to my crotch and when she saw me begin to play with myself, she let out a short, quiet squeal, let go of the vibrator buried inside her, grabbed a pillow and threw it over her face to muffle her moans as she frigged her clit and came hard on her bed.
She began to calm down and removed the pillow from her face. I simply smiled and whispered a polite "thank you for the show" before heading to my own bed.
Then came the weekend. Usually, the house is busy as everyone is home, but that weekend saw a friend of my daughters having a birthday party, and rather than be bored out of my mind at yet another play center, I opted to stay home to get some work done, and put myself a day or two ahead for the coming week. I said goodbye to Kate (my wife) and my daughter and sat down at my desk to get stuck in.
After about an hour (and little progress), I heard the main house door open and close, and had forgotten that Adrienne had gone out earlier for her gym session. My cock, understandably, stirred in my pants when I realized that we were in the house alone together, but I didn't want to push the issue and refocused on my work.
A few minutes later, the door to my study opened and Adrienne walked in, dressed in her active wear (which was looking better and better every time I saw it), and carrying a coffee. She placed the coffee carefully on one side of my desk, then moved around behind me and sat on the other corner, facing me.
"Morning!" She beamed, beads of sweat still clinging to her neck and forehead.
"Morning." I replied, "Thanks for the coffee -- if it is for me, of course."
"No. Sorry," she shrugged, "It's for the black stud with the 14-inch cock I have stashed in my room." She playfully punched my arm. "Of course it's for you, dick."
I chuckled. I was enjoying her company more and more.
"Thanks again." I took a swig. It was perfect, exactly how I like it. I moaned my approval.
"So," she mused, leaning in to me to look over my shoulder, "what are we working on today?"
"Clients. More clients. Just trying to get ahead before the week starts. Then I can maybe have a day off."
"Nice. Don't let me distract you."
...Yeah, right.
As she said this, she leaned even closer, right against my ear. I could smell the sweat and she smelled amazing. She whispered in my ear, slowly and deliberately.
"I'm going to take a long, hot shower -- to clean myself up. While it's not common practice around here, I'm going to leave the door open."
Adrienne sat up, and very carefully spread her legs on the corner of the desk, opening herself up.
"Wide open." She added. Then she leant down, and licked and nibbled at my ear before standing, and heading off to the bathroom. As she did, she placed her arms around herself, and lifted both her mesh workout top and her sports bra off in one pull, leaving her bare back mocking me as she sauntered away, stopping briefly to look over her shoulder with an incredibly suggestive gaze.
Once she was out of sight, I quickly saved all of the work that I'd done (what little there was) and shut down the computer. I heard the shower start running, and as I stood I readjusted my pants to accommodate the thickening shaft of my dick.
I made my way down to the bathroom, coffee in hand, and found it amazing that both major instances of my having some sort of sexual congress with my sister in law both started in the same room. This time, though, there was very little pretense. The steam was billowing out of the doorway to the bathroom, and the shower was in full swing. I braced myself for the eyeful I was about to receive, and as I turned into the doorway, was not disappointed.
Adrienne had stripped down for the shower, and was soaping herself up and down, all over her lithe, young body. She seemed to be paying extra special attention to her hard, eraser like nipples and the bare, shaved space between her legs more than the rest of her body, but her eyes were locked on me, watching me watching her.
I stood there, in the bathroom, like a total pervert, watching as my sister in law cleaned off the grime from her workout. I must have lost focus (well, maybe I was focused on something in particular) when Adrienne snapped me out of it.
"You should sit down, Mike."
I agreed. It was worth settling in to watch the show. I moved to sit on the edge of the bathtub, when Adrienne called out to me.
