Nevertheless, Dan paid it no mind and set up the game on the table in front of her. When it was ready, she sat on the floor with him, and they began to play. Whilst playing, Charlotte instigated conversation regrading their relationship, and how she wanted to be closer to him. When Dan asked how, she bit her lip and pensively thought for a moment. Eyeing him, she said that she wanted to help him more, and that he should fetch her to satiate any need he might have. Since he knew his sister well, he suspected an ulterior motive of some kind, but since it seemed that the idea couldn't hurt him, he accepted it.
Charlotte won, and, as was their tradition, was aloud to order Dan to do something for her, usually a chore or some homework. This time, however, she said that her feet were killing her, and bade Dan to give her a massage. Dan didn't think that he should think anything of it because sometimes he massaged her back and legs, to assuage the pain she often felt, and her feet weren't a large leap from her legs.
At the same time, he wondered if she had used joint pain as a cover up to have Dan touch her. He didn't really mind of that was the case, because nobody was hurt by it. Adopted the same dogma, he resigned himself to the possibility of incest if there feasibly could have been another explanation.
Getting to work, he ran his ran his finger over her soles, and began to knead at them, gradually applying pressure on her toes and the balls of her feet. Though he had never given a foot massage, his sister seemed to be enjoying it, perhaps more than ever before. Her sweat acted as a lubricant, allowing his fingers to glide fairly easily over her soft feet.
Unconsciously, his head had begun to mobe downwards, now almost level with her feet. Breathing deeply, he smelled Charlotte's sweat, sharp and erotic, as he simultaneously got a closer look. Her feet were well taken care of, and there were no calluses or rough patches present whatsoever. As he continued to smell her, he felt his penis grow erect quickly, tugging at his pants. He knew that it was probably visible, but knew that getting up would only draw more attention, so he kept massaging her.
Charlotte let him continue for about twenty minutes, but she eventually called him off politely, and he obliged immediately.
It was Dan's turn to make dinner, and he cooked soup for them. As they sat at the kitchen table, Charlotte apologised and said her feet were hurting her again. Without waiting for a response, she placed her feet in Dan's lap, right in the middle of his crotch. When he reached down with his left hand to begin massaging them, he found that her soles were turned down to his crotch, such that he couldn't see them nor touch them.
The weight of her warm feet against his penis gave him an erection which he knew Charlotte could feel with her feet. Dan glanced over at her, feeling more than a little miffed at having been played by her. She was eating the soup nonchalantly, and stared at her food.
Dan knew that his sister's intentions were sexual, but wanted to prove to her that his weren't. To that end, he gently moved her feet up, and began to massage them with both hands, having finished his soup. While he kneaded her feet, she started to move the balls of her feet, which still touched his erect penis. She moved them up and down against his penis, and he felt it twitch against her, leaking pre ejaculate.
Dan stood up and grabbed his bowl, letting his siter's unprepared feet fall to the floor. As he walked to the sink, he watched his sister, and she never looked up the whole time. Disappointed at his sister's actions, he got ready to go to bed. Shortly after he had brushed his teeth and changed, Charlotte finished and also prepared to go to bed. As they both climbed into bed, neither of them spoke. Dan thought that he sensed regret in Charlotte's face, but he couldn't be sure. Time dragged on, and Dan couldn't sleep. He grew more disgusted and angry at his sister as time passed. He turned and looked at her, ready to confront her. Her back was turned to him, and he heard a wet sound, quiet, but probably noticable if he had paid attention before. His disgust spiked at he realised his sister was masturbating in bed with him, probably thinking about him. Deciding to deliver payback, he steeled himself before deftly sticking his finger down her shorts and panties and into her anus. She cried out softly before beginning to move up and down his finger.
"Dan," she moaned, "Please put it in me." Dan abhorred the thought of fucking his sister and retracted his finger immediately. Repulsed, he got out of bed, and walked out of the room, shutting the door behind him. Stumbling towards the couch, he fell onto it and collapsed soundly into sleep before long.
When Dan woke up, he saw that Charlotte was still in their room. "Good," he thought, feeling more bitter than angry. He felt sick from the alcohol and his sister's antics. Grabbing a book, he read for a few hours until his sister came out of the bedroom. Her hair was ruffled messily and he saw that stains ran down her shorts from masturbating with them on.
"Happy birthday," she croaked, only half awake. Dan realised that it was, in fact, his birthday. He had neglected to mark it on the calendar, and school had precluded his memory of the fact.
Dan didn't want to stay mad at his sister, and hated that he had to angry with her at all. He decided that he needed to talk with her and confront her about the issue. However, his plan was at least temporarily thwarted, as his sister had left him a moderately sized present and had went back into their room, locking the door. Annoyed at her antics, he bent down and picked up the present, the motion making him sick. He went to the trash can, where he vomited. He discarded the wrapping paper, and found his sister's white sneakers and socks inside. They both smelled heavily of sweat, but the shoes' bottoms were perfectly clean. He knew that Charlotte had worn them both specifically for this day.
As he picked them up, he got an erection again. It had been a while since he had masturbated, and his penis painfully pushed against the confines of his shorts. As he walked back to the couch, his arousal only grew. Setting them down, he unbuttoned his shorts and undid his zipper. By now, only one thought filled his mind: "Fuck it."
