We went to a cabin back in the summer. My wife's parents rented it and invited everyone. My wife's sister is very attractive and has a great body so I had often found myself wondering if their pussy would taste the same since they were sisters.

Everyone else changed clothes to go swimming and I was the last one to change. When I went in the room to change I noticed my sister-in-law's clothes on the bed. Maybe it was because I was already horny, but something told me to check out her clothes.

I unfolded her blue jeans and found a pink pair of panties there. I thought about it for a minute and decided that since I would probably never get to eat her pussy that sniffing her panties would be the next best thing. I snatched up her cotton panties and sniffed them. They were very nice and smelled a little like my wife.

I put the crotch of her panties in my mouth and started licking them. yeah, that's a familiar taste. I could feel my cock getting hard and I had a few minutes to kill so I took her panties and started to jack off with them. It felt really good so I kept on stroking getting my cum worked up with my sister-in-law's panties rubbing the head of my cock.

I finally exploded. I didnt' cum _in_ her panties, I just shot on the floor but when I put her panties back I discovered some wet spots on them where I had dripped some cum on them.

After swimming she changed back in her clothes and wore the panties that I had used to masturbate.
