She needed to get fucked, plain and simple. Normally she enjoyed making love romantically, but today she was too horny for that. She needed it hard and fast, and she needed it now. Too bad that they were out camping with their friends, and it was far from nightfall. The four of them had just finished a late afternoon lunch and were sitting around chatting. She glanced over at him, trying to signal with her eyes her needs, but he was too busy in the middle of his story to register what her look meant.
She gently took his hand as if she was just taking it to hold it lightly as he talked, but she was about to let him know what she wanted. You see, she had this little habit of stroking the middle of his palm lightly, and scraping her nail right along it in a very arousing manner. This had become their established cue for I am horny for you right this second, and it usually meant if he didn't excuse himself within the next ten minutes, she would literally drag him away from whatever he was doing. She didn't like to take no for an answer, at least not with sex.
She continued to toy with his palm, as he started having trouble keeping his sentences coherent. She smirked. I got him, she thought. Politely, she got up, excusing herself from their friends, saying that she needed to take a little walk and stretch her legs. She pointedly only invited him with her for the walk. He cleared his throat slightly, cheeks going into a very slight blush. Quickly, he did get up and joined her, excusing himself from the friends as well.
She took his hand, and pranced away lightly, pulling him with her. Once out of earshot, she started teasing him in a low voice.
"Baby, I have this incredible urge to cum for you. I know I'm being a bad girl, but I can't help it today. Can I cum for you, please?"
It was obvious her verbal teasing was having an effect on him, since his shorts were already starting to tent. She grinned at him and put her arm around his waist, and into his pocket. Her fingers weren't long enough to do too much, but they were long enough to graze his cock with every step they took together. She was already soaking her own thong and shorts, even though he was only at half-mast.
