Step Sister In law

I am recently married to a beautiful lady. She is extremely intelligent and a great person. Unfortunately her sexual drive and apatite for straight and deviant sex is much lower than mine. My intention was to be loyal and faithful to her. I figured I could always take care of myself with a little internet porn if needed.

Just before we got married I was introduced to her family. Her mom and dad had divorced and her dad had remarried. The woman he married had an eleven year old son and a daughter who was a few years older. My first impression of the daughter Beth was she was a little to much of a stick and too young to get me excited. My biggest turn on is teen girls that are in the midst of developing and Beth was just starting to develop.


When I got home I was really turned on and encouraged my wife to have sex with me. As soon as I went down on my wife I starting imagining I was eating Beth’s Virgin pussy. My cock was harder and I really gave my wife the all star treatment all the while fantasizing that I was fucking her little step sister.

A few months go by and we are invited back to my wife’s dad’s house again. It was the summer time and they have a pool. When we got there we went out to the pool and Beth was wearing a little two piece Bikini. Beth and her brother were playing in the pool so I hopped in to join the fun. Beth was looking significantly better than the last time I saw her in her jeans and sweat shirt. She was barely covered in a silver bikini that showed her small B tits and a near perfect firm round ass. I got most of my great looks under water because I was wearing goggles. I few times I was right underneath her as she climbed up the pool ladder. I had to take breaks to avoid getting an erection.

When we were done with the pool I went inside to change. When I stepped into the bathroom I noticed Beth’s pants and shirt that she was wearing before we went into the pool were on the floor in the corner of the bathroom. When I looked in her crumpled pants I saw the prize I was looking for and that was her little panties. I could not believe what I was seeing and I was totally surprised that a young teen girl would be wearing a thong. I picked up her soft white cotton thong that had little pink stars on it and put it to my nose. It smelled so good. My cock was instantly hard and I new I needed to relieve some pressure. I started to jack off while licking the inner crotch of her panties. I could tell she had creamed her panties slightly and left her juices for me. I could not believe how turned on I was, it felt like I was a teen age boy. I blew my load in a minute and most of it landed in the sink. I took a nice finger full of my cumm that was left on my hand and rubbed it into the crotch of Beth’s white thong.

We all as a family ate dinner and after dinner we sat down to play some games. I noticed when Beth was sitting down and leaning forward I got an opportunity to look down the back of her pants. To my pleasant surprise I could tell she had not only put the same pair of pants back on but her white cotton panties with the pink stars back on.
