It Began with Sis-in-Law's Panties

About 2 or 3 times a year I visit my in-laws with my wife Ingrid, they live in another region from us so it is over 4 hours to get there by car.

When we stay we stay in my wife's old bedroom, which when she left home, her sister Jill also used, so there are still lots of old things belonging to the both of them in the room.

About 3 years ago we visited and were staying for a week, so I was emptying my case and hanging clothes in the wardrobe, under the bed there were pull out drawers so I put my boxer shorts and socks in there and I noticed about 7 or 8 pairs of panties in there too, some nice silky black ones, french knickers and well as some white cotton ones, I was aroused and thought of my wife used to wear these, so later on when she went for a shower, I examined them more closely, some of them had clear stains on them which excited me, so I took a pair out sniffed them and came into them.

That night in bed I said to Ingrid, that I found some of her old panties in the drawer and she should take them back home and she replied "Oh, they aren't mine those belong to Jill", I froze but was turned on too especially the fact that I had come into my sister-in-law's panties...

Moving on 8 months we went back to my in-laws for a long weekend, I knew that Jill had gone a few weeks after our last visit too, I looked in the drawer and noticed the pair of panties I had cum into now had other stains on them too, was Jill playing along, so I used another pair and left as small trace of cum on them.

Then we went for New Year which was 3 months after our last visit, this was only a few days after Jill had stayed there for Christmas, this time in the drawer tI noticed a pair of panties that hadn't been there before, they were cotton with a black and white pattern, and little bow on the waistband.

Jill had clearly worn them, so I waited for my moment to be alone to use them, but was almost caught by my wife, so I quickly stuffed them into my jacket pocket.

We went home and I hid the panties inside a DVD box.

My wife Ingrid who is 38 and do have a good sex life, but I always found her elder sister Jill who is 41 very sexy and occasionally we had a silly flirt when talking in the past.

6 weeks ago Ingrid announced that Jill was coming up for a long weekend, I felt odd as I hadn't seen her since the who panties thing had begun, she was arriving on a Thursday and going home on the Sunday, Ingrid was excited too as she hadn't seen Jill since Jill moved to France 3 years ago,

My wife asked me to pick Jill up from the airport as she couldn't get the day off work and I had more of my work holidays left than she did, so had the day off, I picked Jill up around 11.30am, it felt awkward but most of the 30 minute journey to my house she just asked about her sister.

We got to the house and Jill asked if she could have a shower as she was warm and sweaty with travelling I said of course, she shut the bathroom door and shouted if I could leave a towel outside the door for her, it was at this point I had a wicked idea, I got the towel and them remembered where I had the black & white cotton panties in the DVD box, so I folded the towel and put the panties in the middle and left them outside the bathroom, I went back to the lounge to watch TV, but then I realised it was a stupid idea and decided to back and take the panties from the towel but when I got to the bathroom the towel had gone!

So I went back to watch TV, 5 minutes later Jill walked in with the towel wrapped around her gleaming body, tucked in at her breast and ending well above her knees, I looked up in amazement, she removed the towel and was wearing the panties, and she said "I wondered what happened to these", my cock rocketed, she then said we have at least 4 hours to kill before Ingrid gets home, so I followed her into the guest bedroom, stripped naked and we went into the bed.

She lay down and I went on top, her nipples were sticking out, I began biting them and licking them, I moved my tongue all the way down her body down to the now saturated panties, Jill took them off and let my tongue slide inside her teasing her clit, she moaned with delight and said "Fuck me, fuck now", so I began fingering her then took my aching cock inside her, went in like a dream and fucked her hard, I came quite quickly though which was a let down, but we both continued in pleasuring each other, she licked my balls so wonderfully and then a great blowjob.

I was stunned when she asked me to finger her ass,(at this point I had never done any anal as my wife Ingrid was dead against it), so I went to my own bedroom and brought some lube in and fingered Jill's ass, she then begged me to put my cock in her ass, so it was a struggle at first and I didn't want it her hurt her be she thrusted and it went in deeper, she moaned in pleasurable way that drove me wild.

We lay on the bed and laughed, we decided to freshen up and have a shower, but we had one together which was amazing and gave her another good licking there too.

The rest of the weekend I kept a low profile, Ingrid had no clue to what had happened, if I had never found those panties 3 years ago then maybe none of this would have ever happened.
