I couldnt believe what I saw!

When I was 21, I took a job working on a farm near my hometown. The guy who hired me, Tim was a real nice guy, but too nice. His wife was sleeping around on him and she eventually took off with her boyfreind to California, leaving him with a 12 year old daughter. I started workingfor him about a year after she left, and things seemed pretty smooth around the place.
It was great working there. I worked a lot since it was just him and I runningthe place, so I got to know him and his daughter, Jessie, very well. Jessie was now 13 and was in 7th grade. She had started playing basketball, and was often down in the barn shooting hoops, often in her bikini as it was summer time out. Her breasts we starting to develop very nicley, and she had very shaply legs for a young girl. Her tummy was flat enough to rest a beer on (i actually did that), and her long brown hair waved in sync with her tight ass as she walked. She was quite a pretty lil girl, but I had never thought of her as an object of sexual attraction. Until I started to notice things about her.
I woke up late one morning after staying up late with a girl the night before, I rushed to work, and arrived just as Jessie was starting her morning chores. I got out of the truck and had to piss like a race horse. She stopped forking hay over to her steers and stared at me for a minute. I ignored her and moved over to go around the haystack to piss. As I walked by her her I looked at her again, notices she was blatantly staring right at my crotch. I passed this off for nothing at first, but when I went to piss, I realized I had a piss hardon from fuckin all night, and it was plainly visible through my tight jeans.
It took me forever to be able to piss, and I thought about rubbin one out, but jess wasnt too far away, so I dismissed that idea. I finally started pissin, and thought about her starin at my hard on. She had to have seen it. I turned to look where she went, and she was standing not to far away, watching me piss. I turned around quickly,” hey, go get your chores done. What are you thinkin?” She smiled, “I just heard from girls at school… ya know, I wanted to see one.” “Well, you had you eyefull, go finish” I said. Jesus, This girl was just ogling my cock. and it did not help my hard on situation. Lucky I was out spraying corn that day, so I was given a chance to be alone for a while to rub one out. and her eyes locked on my cock were allI needed to spurt some jucies. I coudlnt believe it was turning me one. I scolded my self and forgot about her. She was way too young anyways.
About 2 weeks later, I came in from getting some parts for the combine, and Jess was out playin ball in her bikini. she looked damn good, with her summer tan setting in. I wondered if she had tanlines? maybe she lays out when me and her dad are both busy running around this place. Me and Tim went to work on the combine, andd I could hear jess callin her play by play as she drove to the paint in the barnlot. Tim said that Jess had grown quite fond of me, and said he was glad I was on board. He said I worked hard and was quite skilled, and was good with Jess. He offered me a salary position. I needed the job so I said I would stay on for a while. He said it would be good for jess to have me around for a while. I didn’t really know what he meant so I just shrugged it off.
We needed some grease, so I went through the barn to get some while Tim was moving the combine out to the lot so we could grease it. I walked into the pens to check the calves along the way. as I walked in I thought I heard something behind the haystack. I crept closer and heard jess moan. I peeked around the corner only to see jenn with not bottoms on, just the bikini top.
