Joanna was having a great time. She had been dancing with her boyfriend, and anyone else willing, for hours (and there was never a lack of willing dance partners). She was a high-energy dancer and right now she was on a new plateau! She didn't know the host personally, a teammate of her boyfriend, but he was the star on the university rugby team and she didn't want to miss this party for anything. He was very good looking and appeared to be with a stunningly beautiful blonde who Joanna presumed was his girlfriend.
Toward midnight her boyfriend had less interest in dancing and more interest in beers and bullshitting, and by 1AM the beers seemed to have won out as he had become pretty passive on the couch. Perfect, she thought as she gave him a look of disgust and disappointment that nobody missed. As she turned and walked away it was equally clear to anyone watching that she was determined to carry on enjoying herself.
Matt had seen Joanna from across the room at the start of the night and he was watching now. She was very attractive with short dark hair with a slight tuck. She was wearing a thin black dress, cut high on one side to reveal an expanse of tanned, athletic thigh. Her open toed high-heeled red shoes and bright red polished toenails (that appeared to be the only make-up she was wearing) further accentuated her long, firm legs. The outline of her black G-string could be seen when the light was right and it drew his eyes to her absolutely perfect ass and the delicate cleft dividing her firm cheeks that had been toned by endless hours of gym work. The low cut dress revealed an eye-catching cleavage and her breasts seeming to shine in the light.
Joanna had become very comfortable with how men looked at her body. She had always been popular growing up but in a very asexual way as boys tended to keep their distance with her father being the headmaster and her mother the head of the English department. The way her parents made sure she dressed did nothing to spur their courage or curiosity. Her conservative approach to life changed last fall when she entered university and met her boyfriend at a concert on campus. She was painfully shy and he was gentlemanly patient. First studying and then doing other things together, she became more and more comfortable under his gentle encouragement. Soon she started altering her wardrobe in response to his steady stream of complements. She was surprised by the impact the more and more revealing clothes had on her confidence and self-esteem.
Soon she was enjoying the playful teasing from her boyfriend at the attention she got from other guys... guys who were no longer constrained by fear of her father and mother, but guys who, she assured him, were also a bit too late.
While she was dressing for the party in her dorm room he had tried everything her could to convince her to wear just the dress, but she decided that the G-string lines would add an accent of naughtiness to an already revealing outfit. In particular guys seemed to adore her breasts and she enjoyed their gazes so much that she never wore a bra anymore. As a mock concession for refusing to go pantiless she handed him a tube of lotion and asked that he help make sure her breasts were well moisturized. She leaned her back against him and raised her hands back over his strong shoulders, "Make sure there's no lotion left. I don't want to stain my dress", she said with mock encouragement as she leaned her head back and closed here eyes. He did an expectedly thorough job, cupping his hands inside her dress to assure that both breasts were sufficiently moist. Her knees weakened when he focused his attention on both nipples and she playfully slapped the back of his hand as he started sliding her dress off her shoulder. "There's no time for that now", she said as she broke away, mockingly shaking her finger at him as she lifted her dress back in place.
Now several hours into the party, Matt's cock twitched in his pants as he thought of how he would love to get inside her knickers tonight. He could see she had the attention of most of the guys as she now danced with a couple of girlfriends. Looking over and seeing that her date, his teammate, appeared completely drunk, Matt was afraid someone else would make their move first, so he started to plot his opening.
After checking to see that his girlfriend Cindy was safely on the other side of the house and deeply involved with a group of friends, he moved over to chat with Joanna. He soon had her listening intently and laughing at his jokes. He got her a drink, making sure that it was a generous pour. Each time Joanna decided she wanted to dance Matt begged off and moved her toward one of her girlfriends, and used the time to check back with Cindy. He chatted with her and her friends for a while, and made sure Cindy's drink was full before going back to Joanna. After several top ups, he saw that Joanna was starting to look like she was well on her way to joining her boyfriend's drunken state.
