Many thanks for the helpful comments received, as I am very new to erotic story writing. Whilst, not getting carried away, it is encouraging and so without further ado I shall launch into the next episode of this fantasy. The first few chapters are very short but essential to get into the story and enjoy not just the eroticism but to understand the emotions and characters in the story.

I felt myself awaken with an overwhelming need to pee, it was dark and I felt disorientated. Where am I? I thought, slowly peeling open my eyes and looking around the room. In the shadows, next to me lay Mary. Obviously in deep slumber, she looked relaxed and comfortable even with the cast and bandages on leg and arms.
"Uhmm!" I growled appreciatively settling my eyes on the shadowy vista of her boobs which nestled softly on her rib cage. Her head and upper body, raised with numerous pillows, leaned forward slightly accentuating the shape and softness of the boobies. Her aerola were rubbery and warm to the eye, crowned by pink, heavy nipples. Despite my urgent need to piss, I felt my hand lazily drift over to rest in the shadowy cleavage, luxuriating in the warmth and softness, gently feeling the soft contours and bringing the nipples slowly to life.
Growling again, I lowered my head to rest comfortably on a pillow, within easy reach of bosom heaven and carried on softly exploring, squeezing and pressing lightly, then running finger tips around each boob until the nipples grew turgid and stood out tall and proud. My need to pee was fast becoming unavoidable, so with a sigh took hold of my very erect penis and lifting carefully off the bed placed it on her slightly open lips.
"Mmmm!" Mary moaned, sucking me into her hot mouth. The urgency of needing to pee badly together with the lust awakened from stimulating her boobs had me rigid and sensitive. Sensations of hot mouth, wet rubbery tongue and ridged teeth caused me to moan continuously as ribbons of pleasure ran through my cock and along my nerves to the brain sensors.
"Ohhhhh! Got to piss, though don't stop. It's incredible." Easing my cock head out of her mouth she smiled.
"Go and piss. I don't want you letting go in my mouth. But, I need to pee too."
"Give me a minute and I'll get your pan."
I rushing to the bathroom, waited for the stiffness to recede before letting go then picking up a mug of warm water and a hand towel returned to place the bed pan for her, emptying it and returning in a jiffy.
"You must need a rinse after all the cummings and goings," I stated casually a smile on my lips as I placed a towel under her bum, soaked the hand towel and rinsed her thoroughly.
"Where were we before all these interruptions?" I asked rhetorically positioning myself so my mouth was on her vagina and looking into her eyes.
"Ooh! Kid brother being naughty, is he?"
"Well now! Just starting to be mischievous, wait till I really get naughty." I replied, pressing my knuckles deep into the crevice of her ass and rolling my fist in a circular motion digging into her anus and spreading her cheeks wide.
"So bold."
"And beautiful! Taboo...is just the start of it. We may as well throw out all niceties and get down and dirty." I chuckled, licking her from bum hole to clit with one big wet tongue.
"Goddd! That is scrumptiously dirty. Yes! Get Down and Dirrrrttyy."
