My s****r in Law

Several years ago I had to move to my parents in law as we were moving house. They were well off and had a huge house an lots of room so we stayed there for three months whilst we bought a new home. We had a lovely big en suite room and a massive king size bed. Living here was a bit of a pain but it had two positives. Firstly the mother in law was a true Milf. in her 50's but posh and vey well turned out as they say. Also my s****r in law was 17 at the time. I had known her for her entire life and watched her grow up from an annoying k** to a very fit well endowed young woman. Luckily for me I had a job where I started early and came home mid afternoon. I had the whole house to myself for a few hours every day and what else is there for a man to do on his own but wank. Every day for the first month I wanked. It was great as I had a selection of used panties to sniff and taste. Every day there were fresh pairs in the wash basket. So today we a little different.

After about 10 minutes I started to feel the tale tell signs and I could feel that magical moment approach. I lay back on the bed and took the gusset of her panties and placed it into my mouth so could taste her and with the other hand played with my balls. The feeling was so intense and I could feel my balls tighten an I started to cum. I came really heavy that day and shot my load over my tummy, chest and over my face. As the last squirt pumped out I glanced across to the gap and I could see her legs giving way as she came herself. As se wobbled she looked up and we made eye contact. We had both been caught out. she closed he door quickly. Later that day we were all sat down for dinner. We sat opposite each other and barely made eye contact. I tried to be normal but just a couple hours before we had shared this wonderful experience. The next afternoon I prepared for my daily wank as normal. Was she going to be ...
