Sorry for the HUGE delay in submitting this final chapter. This was due to a number of reasons that I won't bore you with. Thanks to those who have submitted feedback and have enquired about the final chapter.
Next time I write a story I'll try to write the whole thing and submit it a chapter at a time rather than try to write a chapter at a time as I submit the previous one.
Hope you like this anyway.
***************
Although I hadn't drunk much alcohol the previous evening, I had enjoyed a few drinks. It had taken me a while to get to sleep, too. It was hardly surprising. I mean, I'd never before slept beside a married woman, let alone one whose husband was dozing on the other side of her on the king-sized bed!
I had partnered Lucy and Bill, with the raunchy Lucy sharing her favours and attentions between us. I was now discovering the true naughty allure of swinging. It wasn't just about having different partners. It was all about the excitement and shame of being watched by the husband as you enjoyed his wife. But it was also about the sordid delight of watching - and joining, as the invited interloper - man and wife in what should be their most intimate and private act. To be truthful both elements were equally exciting. And equally shameful.
That, along with the excitement of the last few hours, as well as the limited amount of sleep that I had recently had over several nights alone with my aunt in her bed, caused me to awaken slowly and gradually.
The curtains softened the daylight that filled the room. I was lying on my side, and as I opened my eyes I saw before me the slender, naked back of a woman, her dishevelled chestnut hair veiling the nape of her neck and resting on her shoulders. My eyes followed the soft, smooth skin and the contours of Lucy's back, running down its hollow to where it disappeared under the bedsheet, which reached just above her waist.
I recalled being vaguely aware of Bill getting off the bed at some point in the night, and, sure enough as I glanced across, he was lying asleep on a futon that faced the bed on which I was now lying next to his naked wife. The whole situation was surreal, and I blushed with embarrassment. I knew he had only done it so he could sleep more comfortably, but it almost seemed that he had bestowed his conjugal rights on me. He was breathing deeply. He had drunk quite a bit more than I had.
I was getting hard as I studied the form of his wife Lucy, recollecting the feel of her body and skin, and the sensation of being inside her married, mature body. I also thought how just a few hours earlier she had alternated her favours between her husband and I.
Despite all that had happened between us, I was too embarrassed now to take the initiative in Bill's presence. Instead I contented myself with gently lifting the lemon-coloured bedsheet that covered us both, to gaze on her better.
Her hips were not broad but they did flare nicely from her waist. Similarly her backside was not big, but it was curvy and in good proportion to her slender frame. My eye was drawn to the cleft that separated her buttocks, and blushed as I thought of the occasion the previous week -on this very marital bed, in fact - when she had even invited me to have anal sex with her. As I glanced once more at her husband I blushed deeper, and at the recollection of how, at her insistence on that occasion, I had called her lewd names as I came inside her.
It was only then that I was suddenly aware of another presence. On the bed, beside and behind me as I lay on my side. I have already mentioned that I awoke gradually. In addition, the sights and feelings I have just described all occurred within just a few moments and flooded my senses, making me oblivious to other details. I rolled slightly onto my back and twisted my neck round.
Close to my face and near the headboard was a pair of feet. Attached to it was a pair of strong calves and long legs. There was no doubt whose they were, but instinctively I rolled further over and turned my head to check.
Aunt Anne's pale pink chemise was almost entirely plain. It was made of satin, and reached just below her knees. Under it, her flattish stomach and little breasts rose and fell with her breathing. She was lying the opposite way to Lucy and I, with her head at the foot of the bed and her feet by the headboard, to take up less space beside us. The upper bedsheet was loosely bunched over me and did not cover her at all. Her face looked serene as she lay there asleep, her dark straw hair framing her face untidily yet naturally. She must have joined us on Bill and Lucy's bed some time after Bill had moved to the futon and when the three of us were asleep.
The satin of her chemise gleamed a little in the soft daylight, which created subtle highlights and shadows on the fabric. The stretches, creases and looser folds in the satin where it hugged or draped over her seemed somehow very sensual and I watched the rise and fall of her stomach and little breasts under it with each breath she took.
I rolled over onto my back and tilted my head to look up her hem. Her inner thighs were parted a little and were slightly shadowed inside the pink satin. Her posture hid her crotch from view but by now I well knew what it looked like, and imagined it as I gazed upon where the soft pink fabric covered it. I admired the half-discernible curve of her mound through it.
I felt my erection begin to harden.
I also felt acutely embarrassed, though. As far as I knew, only Lucy knew Aunt Anne's and my secret. There was no way of knowing whether her husband Bill would be outraged or turned on by it. I was shocked, too, that my aunt had created such a situation.
