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.
Once they had walked maybe 100 feet away from their friends, she steered him to the right, and into the forest, away from the path. She was taking him not too far from the campsite, to a little cove with a nice flat rock in the middle of it that she had found the day before. She giggled a little at her naughtiness; the rock was close enough to the campsite that if they got too loud the friends would be able to hear them. This turned her on even more and her netherlips started to throb.
In a couple minutes, they reached the flat rock she had been thinking of all morning. Smiling at him, she removed her hand from his pocket, and turned him around to face her. She crouched down in front of him, and quickly unbuttoned his shorts, pulling his boxers down with them. He was getting more aroused as the air hit his cock, throbbing and growing.
She was going to tease him first, without giving him a full blowjob today, because, well, she's a woman and that's what she can do. Instead of taking him into her mouth, she started to run her tongue up his shaft, lightly circling the head each time. She licked him up and down his entire cock, but she never took it into her mouth. Finally, when his cock was coated in her saliva cooling in the light breeze, she took him into her mouth, but only his head. She licked little circles around lightly, with barely there touches, stopping when she tasted his precum coming out.
