The stars were almost in agreement that evening: my sister-in-law had a job interview the following day, very close to our house, and my wife was away on business trip.
We naturally consented to her request to spend the night at our house due to scheduling conflicts and geographical limitations related to the interview.
When she arrived in the evening, we ordered pizza, turned on some music, and--of course--drank alcohol while practicing some interview questions.
I filled my glass and poured her a drink. Sitting next to each other, we conversed for a bit and then drank for the next hour. We had the strange sensation of total freedom, as if a weight had been taken off our shoulders.
Nobody could have predicted at this very time that my sister-in-law's sleepover would end with them sharing a bed for the whole night.
Oddly enough, as time passed, we both undressed a little bit, most likely because it was already late and too hot outside, and bedtime was approaching.
She was wearing an oversized long shirt (as well as a black seductive thong that I found out about later), while I was wearing only a T-shirt and tight boxers. I started to feel like there was more sexual tension and that I was fucking turned on after we had consumed all of the booze that was on the table.
You could smell the sex in the air, but there was no touching or flirting, up until the moment that altered everything.
As we got up to fetch another beer from the kitchen, we unintentionally tripped over each other. We both said, "Sorry," at once.
We chuckled, but Kim immediately fixed her unblinking gaze on my expanding bulge. "Do you have a weapon in your pocket, or are you just thrilled to see me? Sorry, it was so right to the point to use this old phrase regarding your 'situation','" she said while smiling.
And before I knew it, She simply knelt down, removed my underwear, put her right hand around my cock, and drew it toward her as I was trying to think of a response. She smiled broadly as she raised her head to say, "Seems pretty heavy."
I was speechless.
Kim bent forward and licked straight up the precum that had formed at the tip. She then raised my cock to a proud upright position, and while I was trying to come up with an excuse not to continue with this, I felt and watched her lips curl over my cock.
She shoved my cock deeper and deeper down her throat till it stiffened, and she silently gagged. As I groaned under my breath, simply couldn't believe what going on, I tried to fight my temptation, so I retreated a little distance, and collapsed onto the couch.
