Helen's skirt had eased back along her thighs as she relaxed in her seat. Although I was trying to be discreet in admiring her long bare legs, I think she must have noticed, but to my joy, she made no attempt to cover them. Although I was enjoying myself, the effects of a long day plus the drink made me surprisingly drowsy, and we fell silent, relaxed in each other's company. The cabin lights were dimmed and I asked Helen if she minded if I had a brief snooze. She smiled and signalled for a flight steward to bring a blanket for me.
I had almost drifted off, when I felt the armrest between us being raised. Then to my surprise, a hand moved under the blanket and gently rested on my upper thigh. The touch set my pulse racing, and I felt my cock stir immediately. I sat perfectly still, and then as if in my sleep, I moved the leg she was touching nearer to her, giving easy access to my rapidly increasing bulge. To my delight, her hand moved to rest gently on my hard-on. After she had lightly stroked it through my trousers with her long nails for a moment or two, I decided to give up the pretence of sleep. As we both sat with our shoulders touching in the dim lighting, I moved the blanket so that it covered her lap also. As if prompted by my action, Helen removed her stroking hand. Without a word, she gave me a secret smile, which hardened my cock even more. She raised the armrest between her and the aisle seat and curled up on her side, with her knees drawn up, as if sleeping. I spread the blanket over her hips, and was relieved to see that the sole passenger on the other side of the aisle was obviously asleep.
From being sleepy, I was now high on adrenalin. Every nerve in my body was on fire, and my cock was straining against my trousers. Cautiously, I slipped my right hand under the blanket and rested it on her thigh just above the knee. Ever so slowly and tentatively, expecting a rebuff any second, I eased her skirt back over her thigh and buttock. Helen's skin was warm and silky, and, as I leant over her, the floral fragrance of the scent she was wearing made my head swim with delight. She had extended her upper leg forward and over the other, and as I slowly slid the fingers of my right hand along the silky inside of her lower thigh, I realised that in my concentration, I had almost stopped breathing.
At last my, trembling, fingers reached the crease between the cheek of her ass and her thigh. As they touched the thin silk band of the crotch of her thong I paused.
My fingertips felt her dampness through the material when I slid them over the smooth gusset. I lightly trailed them over the bulge of her pussy lips, swollen and pressing against the restraining silk. With two fingers, I traced the crevice between them, until they rested against the damp patch, which covered her entrance. Helen stirred slightly, and made a little sound in her throat. She moved her upper leg a little further forward, giving me more access.
With Helen to my left, I slid my left arm gently behind her back for support, and leant further over her, as the plane carried us through the dark night. The searching fingers of my other hand slipped easily under the thin material. When they touched the hot, moist entrance, brushing past wisps of fine hair, Helen instinctively tightened her vaginal opening. But in seconds I felt her pussy relax under my gentle probing. My mouth was dry, my cock was throbbing, and I expected to awake from a dream any second.
But this is really happening, I told myself, as my fingers tingled madly from the feel of Helen's clinging inner lips. I continued my cautious exploring. I circled the wet, sticky entrance, stretched partly open by the position she was in. Then at last my forefinger glided smoothly into her velvety opening, as far as it would go. I felt it touch Helen's cervix and the walls of her pussy clenched tightly around it. I slowly withdrew, and entered her again with two fingers. She uttered another muffled sound, and her breathing had become unsteady. Slowly I circled her clinging pussy, probing and stroking, but I couldn't reach her clit in that position. Finally Helen couldn't stay still any longer, and with a soft groan she pushed down demandingly against my hand, slippery with her secretions. The movement startled me for a second, and I almost withdrew my hand. Spurred on by her encouragement, I was going to make the most of this astonishing opportunity. I leant further forward, gently kissed one of her closed eyes, and continued stroking my fingers in and out.
To my joy, Helen opened her eyes, and her lovely wide mouth curved in a smile. Reaching behind her, she took my hand and slowly eased my fingers from her pussy. She swung her long bare legs round and sat up. After glancing round to check that the passenger across the aisle was still asleep, and still wordless, she slipped an arm round my shoulders and we kissed. I drank in the delicate perfume from her hair, while our lips and then tongues met and explored, slowly and gently. Although I was wildly excited, Helen seemed to have a calming effect on me, as I followed her lead. It felt so different to the frantic sexual wrestling matches that I had experienced with other women. Her lips felt so soft and yielding, and yet her tongue was so firm in contrast and danced teasingly against, and then away from mine. I don't know if it was the effects of the unusual situation, or my memory playing tricks, but I still think that it was the most sensual and skilful kissing I have ever enjoyed.
After a moment or two, Helen took my face in her hands and looked at me in the dim lighting. I must have had an anxious look on my face, for she smiled reassuringly at me. Even in my high state of sexual lust, I was totally captivated by the sheer beauty of her smile, and I remember that my heart actually seemed to miss a beat, just as they describe in songs.
"It's alright," she whispered, in that lovely French accent. While gazing into my eyes, she freed her top from her waistband, and reached back to unhook her bra. She eased her skirt right up to her hips, and in one smooth movement raised her hips and slipped off her thong. Pausing for a second to touch my cheek with her warm fingers, she lay down on her side again, tucking her legs back into that position of easy access. I gaped at the glimpse of the lips of her pussy for a second, before covering her with the blanket. The plane was silent, apart from the steady drone of the engines, and no one was moving around.
