Wearing only my bikini briefs, I settled on my back on the rug, glancing around. Hidden in a hollow in the dunes, we were out of sight of all but the most determined observer, and I relaxed into position. Grinning at Karen, I grazed my hand against her thigh and motioned to her to proceed. Leaning back, she raised her left leg and, with her hand on the rug to steady herself, she stretched over, straddling my waist. She was still resting on her knees, and had not yet settled herself on top of me, but the sight of her gorgeous body, her dark bush and round, firm breasts, sent a shiver of excitement through me. Falling forward, she placed her hands either side of my head and reached towards me, her breasts dangling closer, ever closer to my receptive mouth. Swaying gently, they came within touching distance and I slipped my tongue out to reach her right nipple. As she felt my touch, Karen arched her back, and her breast fell into my mouth, filling it with its peachy perfection, and I sucked at it hungrily, biting her nipple, grazing her areola, running my tongue around and around her skin, the feel of her firm, full breast in my mouth filling me with anticipatory delight.

Finally, she drew away, pulling her breast from me, and I watched as she straightened and sat upright on top of me. She wore a curious expression, partly terrified but partly excited, nervous about the turn of events but, in her seated position, in control. She sat back on her heels, and I felt her weight come to rest on my stomach, heavy but indescribably intimate, her flesh pressed to mine. I stroked her thigh with my finger for a moment, and then Karen slid herself up my body, until she was sitting on my chest. Her pussy and bum were now resting on my breasts, and as I considered this, considered my proximity to her sexual centre, I was overwhelmed with lust. Looking down, I could see her lips, pink and puffy, and her slit, enticingly opened to my view. I turned my head and kissed her thigh, lapping my tongue against it greedily. Karen sighed and pressed her thighs tighter against me: I loved the feeling of her constricting me, using the weight and strength of her body to keep me in position, forcing me to do her bidding. Anything she wanted, anything.

Finally, she laid both hands on the crown of my head and raised herself from me. Sliding her knees on the rug, she shuffled forward and I held my breath as this vision of beauty towered over my head. Her thighs were pressed against my ears and, as I looked up, I had the most amazing view of my new lover, dominating me, a giant perched above me, her goddess's body stretching upwards, seemingly into infinity. I looked at her thigh, right next to me, the skin so smooth, so fresh, so firm, and raised my view upwards. There was her pussy, hot and wet, awaiting my ministrations, and her dark bush, thick and proud; and her flat stomach, with protruding belly-button, rising to the magnficent contours of her breasts; those breasts, incredible, brown nipple-tipped breasts, on which I had already been privileged to feast; and her neck, long, elegant, graceful, drawing one's gaze inexorably to her face, a vision of perfection, staggering, stunning, electrifying. I felt, at that moment, a deep sense of honour, that this woman should allow me the opportunity to give her pleasure.

And she began to sit down.

I thought I would faint with excitement as her pussy came closer and closer; the heat from her thighs radiated against my cheeks and her smell - raw, heavy, laced with sexual promise, filled my nostrils. As she made to sit on me her pussy lips parted, as if opening themselves for my tongue, and I stretched out to meet her. Finally, exaggeratedly, stretching the moment to infinite length, she rested herself on me, and my lips felt the first, perfect, touch of her pussy.

My tongue was stretched as far as I could extend it, and I could feel the tendon underneath straining under the effort. I rolled my tongue against her pussy lip, feeling it hot and moist to my touch, tasting her juices. Karen pushed down fractionally and my tongue slipped into her pussy; my nose was pressed against her bush as I began to explore this new territory, my tongue slick with her fluids, flicking up and down inside her. I bit at her right lip, drawing it into my mouth, its velvety texture filling it, and grazed my teeth gently against her, again and again. I repeated the action with her left lip, and then lapped expansively with my whole tongue, the length of her slit, upwards towards her clit.

Karen moaned as my tongue came into contact with her clit. Once more she grabbed my head as she lowered herself again and this time sat firmly on top of my face. Pulling my head upwards, she pressed herself hard against me, her full weight resting on my jaw, her pussy clamped immovably on top of my mouth. I opened it wide, and she slipped further down on top of me, so that I was pinioned, helplessly beneath her. As she sat forward, her bush pressed firmly against my nose, I was suffocated and could only lap obediently at her pussy. She was soaked, and her juices covered my face and mouth. Cocooned by her body and thighs, I was hot and claustrophobic and, unable to breathe, getting increasingly short of breath. Finally, Karen sat back slightly, and I grabbed a mouthful of air. As soon as I had done so, Karen thrust forward again, once more allowing my mouth to do no more than service her urgent needs.

This time, my nose had rested lower against her, and it was now pressing hard against the top of her slit and her clitoris. I could do nothing about it, but Karen was gyrating above me, and I knew that my nose was hard against her clit, pressing directly on it, stimulating it. I continued with my tongue inside her pussy, feeling her urethra and drawing circles around it, probing deeper and deeper, as far as my tongue could stretch, and lapping up and down the length of her gorgeous slit.

Every thirty seconds or so she raised herself slightly to allow me air, and then clamped herself to me again. Each time, my nose was planted hard against her clit and she rode herself against it with increasing vigour. Imprisoned by her, I could nothing but service her pussy, continuing to lick, rub and suck. I noticed that whenever I went near her urethra she let out an especially loud moan, and so I concentrated heavily on that, pushing my tongue against the tiny opening and sucking on it.

I was getting exhausted, and it was with relief as well as excitement that I felt Karen's thighs tense and buttocks clench, as her climax began to develop. She rose to allow me one final breathful for the final assault, and thrust herself hard on top of me; her weight was almost overwhelming, a powerful force pinning me into place. I lapped frantically at her as she bucked and reared above me, her hands gripping my hair and pulling me hard into her. I felt her arse contract and release, over and over, her pussy lips gripping my tongue tighter, ever tighter, and she emitted a shriek. As she did, a spurt of fluid projected from deep inside her, straight into my mouth, and I swallowed it hungrily. I was fast running out of breath, and becoming mildly panicky, despite my intense excitement, and I was relieved when, finally, Karen raised her bulk from me. She hovered just above me as the final, diminishing waves of excitement pulsed through her, and I continued to lick very gently at her hot and swollen lips.

"My God," she said, "I've never known anything like that. I've dreamed about doing that, but I never thought it would happen."

I smiled. "I did say I'd do anything, didn't I."

"Yes," she said, in a curious, faraway voice, as though she were thinking of something else. It could have been simply that she was remembering what had just happened, but I had a suspicion there was more to it.

"And is that all you've dreamed about?"

"Hmm?"

"Is there anything else you've fantasised about?"

She said nothing, but bit her lip. Clearly, there was something else.

"Come on," I said. "Tell me. I've told you, I'll do anything."

She paused. Looking up, I noticed that here nipples were jutting out once more.

"You might change your mind..."

"I won't."

"Okay," she said. "What I want, what I've always fantasised about doing, is peeing on somebody..."
