Babysitting Neigbor and Daughter

I read this site all of the time and the stories are the best part so I figured it is my turn to submit mine. I was 17 and this story started with me babysitting for my neighbors who had a son who was five. Sometimes when I babysat there older daughter who we'll call Lauren who was 14 was home as well. She is really cute but she is the age of my younger sister and I never really thought about her like that. We will get back to her. So when I would be up there and after the little guy went to bed I would get bored a lot of the time when no one else was around or even when he was around. Sometimes I would start to get horny and the thought of being in someone else's house and maybe jerking off really started to get me going. I started to walk around there house exploring things and I'd start to get a boner. It was great because if the kid was sleeping the whole house was all to me just to walk around horny and explore. I would walk around the mom and dads room but the room that really intrigued me was Laurens room. The whole girly atmosphere and thinking of the things that could have happened in there like naked girls and things like that even though I never really thought about Lauren like that. I started getting braver everytime I went there and I took a peak in her drawers once and saw all of her underwear...my boner was huge. Another time when the boy asked me to go down into the basement to play frequently I noticed the washing machines and baskets of clothes near them with some girly items in them. Boy was I excited the possibility of seeing some of Laurens worn underwear made my dick so hard I just had to look. I found 2 pairs of little cotton panties the first time and I looked inside at the crotch to see clear whitish marks on both of them and I almost came. I sniffed them and told the kid id be back in a while and went to the bathroom and wrapped the girly dried wetness of crotch around my 7 inch rock hard dick until I shot my load all over the toilet. This made me start to look at Lauren a little different and I realized how cute she was and how hot her developing teen body was. She had dark hair with really sexy eyes and a little bigger than A cup developing mounds that she always kept in sports and training bras. She had a cute little ass and always wore tight little shorts and when she was around I started noticing her underwear lines thru her shorts on her tight ass. She started being there a lot when I came over. Besides being a panty lover girls peeing turns me on so I would take any chance I got to sneak near the door when she was going so I could listen to her drop her little shorts and underwear and I would get to hear the pee coming out of her little pussy and splashing off the water it gave me the biggest boner to think she was in there with her legs naked and spread open. Sometimes she would still have on her school girl outfit from the catholic school she went to. I would be sure to tease her when she went up the stairs and race up behind to catch a glimpse of her panties underneath her skirt. We would play wrestling games with her little brother and she would grab me in some weird places sometimes haha and I was nervous cause of the age thing so only subtly brushed my hands off her little boobs or ass occasionally and we would just giggle. I loved when we were wrestling and I got beav shots thru the sides of her shorts and saw her undies. One time she had on grey undies underneath and I swore I saw a little wet spot on them when she was rolling on the ground and I got a peak of them. Sure enough 2 days later when I was there I found the pair down in the washroom and saw there was a whole lotta white and clear girly stuff in there seemed like a real lot tho. I added to it with some of my stuff and put them back haha I couldn't help it. Another time we wrestled and I noticed that same little wet spot when I got a peak. We just relaxed and I put her brother to bed and we were watching tv on there big leather couch and she said she was going to go up to her room for a while. After a while of her not coming down as it was a Friday and usually the only reason she went to her room was homework n she wouldn't on a weekend I snuck up to see what she was doing. I crept to the door at the end of the hall and put my ear to the door to listen. I didn't hear anything at first but then after a couple seconds I heard a soft moan. I thought to myself noooo wayyyy as my dick sprung 7 inches long n pretty much smacked the door haha. I kept listening and she got louder and it sounded like she was riding a pillow or something and it seemed like she got off as she sped up and let out a gasp and then stopped so I quickly went downstairs so horny but couldn't do anything and didn't want to get caught. Next time I was there my little bud helped me out again as he wanted to play the wrestling game and lauren joined it. We got heavier into it this time and she really seemed to rub my dick a few times I was getting scared I was going to get a boner but I played back grabbing her and once pinning her down with my knee between her legs and I rubbed it up n down in between her legs and I could feel she was hot there on my leg I was so turned on. We later stopped and were on the couch again when her bro went to bed. She had her legs crossed in her lil shorts and her hand was between her legs innocently. It looked to me like she was rocking a little tho and I got very distracted from the tv. I noticed she really was and I started getting hard and just curiously I asked Lauren what are you doing? She was kinda scared but then had an angel like smile and said "I dunno I get "itchy" down there sometimes don't u?" and she smiled. I was dying and I said well what r u going to do about it. She said she really needed to "finger her kitty" and that I got her all horny. I WAS soo horny I told her she should do it and she said only if I did too. I couldn't pass this up so I said okay....and I gradually put my hand down my pants and touched my throbbing dick. She spread her legs so her knees were up in the air with feet on the ground and put her hand down her shorts...i almost died/exploded. She started breathing heavier and I was ready to squirt all over soon when she let out a moan and her whole body tensed up and I came all over. It was amazing she had a huge smile when we were done. We did this a few more times when I was there when her bro went to bed and we did it with pants off and I got to see her 14 year old shaved little beaver soooo hot and all wet with her fingers in it. We never touched each other as I didn't think it was right but boy was it exciting to watch Lauren so horny for cock fingering her wet little cunt. I hafta go now as this story made my dick so hard thinking back to this so I need to go jerkoff and cum all over!
