When she first began working there, he noticed how attractive she was. Dana was Korean-American, about 5'6" tall, about 130 lbs, black shoulder-length straight but nicely styled hair and dark eyes. She had a nice curvy figure and a pretty face with full "blow-job" lips. He loved it when she wore her bright red blouse (it looked so good against her back hair) and black genie pants outfit. Dana had a friendly demeanor, often joking around and laughing. Sometimes when she was talking to someone in the office who was sitting at a desk adjacent to the one at which she was standing, Dana would lean forward onto the desk, and he would get a bit aroused seeing her curvy ass sticking out. Her breasts weren't large, but they definitely were sexy. When Dana wore a white blouse and the temperature was chilly in the office, it was plain to see her nipples were dark. Not only did her nipples become erect, but the area around her nipples seemed to jut out as well. He found this extremely erotic.
They would converse from time to time, mostly about nothing, and she would flirt subtly once in a while. She had a bit of a low, breathy voice, also a turn-on for him. Dana was engaged and lived one block over and a few blocks down from him. When her fiancée was not around, she sometimes would ask if he was busy on the weekend and they would meet, sometimes alone, sometimes with other friends, for something to eat, to play a little tennis, to catch a movie, or whatever. Even though she was an attractive woman, she was also like a buddy who just wanted to hang out.
Dana was very much into bowling due to her fiancee's influence. They would join bowling leagues together and she became quite adept at the game. One day at the office she asked him and a couple of other friends if they would be interested in joining a summer league. They all accepted and formed a four-person team. Dana would show up in jeans or sweats. He would watch her from behind as she prepared to roll the ball. She had a routine where she would stand holding the bowling ball up to one side and sort of "dig in" with her shoe, causing her hips to swivel from side to side. She would then go into her delivery, ending in a bent over forward position leaning to one side.
Her ass cheeks would wiggle beckoningly and come to a halt in a delicious position. She was aware he was watching her because her girlfriend on the team would tell her when he was not within earshot. One night before the bowling session began, he was standing near the lane chairs checking out the standings and stats for the week. Dana arrived, changed into her bowling shoes and walked up next to him to share a peek at the stat sheet. She purposefully pressed her left breast against his arm as she pretended not to notice she was doing that. He was amazed how hard her breast was, sort of like a Spalding ball. The team started the season in tenth place and finished in first place in the last game of the last night.
A couple of weekends after their bowling victory, he was home (he lived alone) doing some light housework. The doorbell rang and he wondered who it could be, as he rarely had visitors, especially unannounced. He opened the door and there stood Dana in t-shirt and jeans with a light windbreaker and wearing the small-lensed, brown thin-rimmed eyeglasses she sometimes wore. Needless to say, he was surprised to see her. She smiled enthusiastically and said "Hi. I was taking a walk and thought I'd drop by." Her fiancée was working all day and she wanted to get out of the house. He was glad to see her and welcomed her in. She had never been to his place and the first words out of her mouth after she entered were "It's so fuckin' clean!!"
