Fortunately for me, I only needed to wait a mere 24 hours to receive the final part of my birthday present from Denise.
After a full day at work, Denise returned to my apartment just after 6 pm.
Wholly anticipating something very special from my lover, I had high hopes that we would leave no stone unturned in making the most of my annual celebration.
Denise had spared the nurse's uniform on this occasion, preferring for a pair of modest slacks, which highlighted the shape of her hips and bum along with a buttoned shirt up top.
Wasting little time, we once again commenced our session in the bedroom, much as we had done the previous evening with Denise pulling down her pants bent over and me beginning to touch her across her large crotch panel.
Denise knew that her Size 14 white cotton underpants had turned me on so much, with the larger crotch panel offering more absorption from her between-leg openings and more staining and odour for me to enjoy during our love-making sessions.
I could tell immediately that Denise was not wearing a pad tonight.
As much as I had enjoyed finding soiled sanitary pads inside her big white knickers as well as finding some in the trash of her bathroom, running my fingers over her soft, smooth crotch pad was so very exciting for both of us.
For me, it was feeling the soft sensuality of her cotton crotch panel knowing this thin strip of material was the only thing between my fingers and her tender, mature genitals.
For her, it was the feeling of me touching her here and knowing there was even one less layer between my searching fingers and her most private of female body parts.
Denise relaxed into a deeper, more open squat position whilst on all-fours, in order to give me better access to her undercarriage as my fingers worked softly but ever-more-firmly across the width of her crotch.
Denise's breathless moaning had begun as my strokes must have been contacting her erogenous items – labia, clit, vaginal opening and anus – individually and all at once.
"Mmmmmmmmmmm..." I joined in, "I love touching you across your big undies like this...Mmmmmmmm...they're so soft in between your legs."
"Mmmmmmmmmm..." Denise reciprocated, "You know they've been in between my legs all day, so they should be nice and 'spicy' for you right now!"
"Spicy, eh?" I was starting to gibber.
Before I even had the chance to contemplate the fresh spiciness on the inside of Denise's undies, she continued at full speed.
"Mmmmmmmmmmm...I've been passing so much gas into my undies today! My bowels have been building up all day and there's been A LOT of gas! My undies have been absorbing so much of it so I hope there wasn't any 'follow-up'. "
My erection doubled in size almost instantly.
"I'm happy to check for you if you'd like!" I replied cheekily.
"Would you do that for me darling?" Denise asked of me earnestly.
Taking that as permission, I slowly began to slide Denise's big Size 14 underpants down over her wide bum and hips, at first revealing her dark bum crack, her large, white buttocks and eventually her undies were down far enough that I could see right inside them – the most startling and arousing view was that of her stained crotch panel, which now faced straight back up towards me from having just been between her legs.
I was somewhat surprised the slightly yellowish stain was not more pronounced although it appeared painted in an almost perfect length across the vaginal strip of her wide crotch pad.
"Ohhhhhh Denise!" I said with controlled fervour, "I can see your panty stain down in between your legs!"
After a few moments considering this, Denise replied with, "It's especially for you! Happy birthday!"
Unrestrained, I bent down towards her bum and exposed underpants. Being able to approach the inside of her undies from behind gave me the wonderful opportunity to savour any odour that Denise had produced from both between her legs and from the inside of her knickers.
"I actually had on a pad this morning but took it off around lunchtime to let my undies absorb everything directly and give you more of a present!" Denise graced me with this exciting extra information.
"You've done so well to keep your undies as clean as they are then!" I complimented Denise sincerely, whilst also beginning to feel like something of an authority on feminine hygiene!
"Why thank you darling!" Denise gushed in return.
By now I had positioned my face down between her legs with her bare bottom within an extension of my tongue and I desired more than anything to press down towards the sacred realm of her discharge-soiled cotton underpants.
"Come down as far as you need to my darling...I want you to get close!" Denise offered.
With my left hand slowly but firmly stroking my cock, I used the spare right to gently push Denise's dirty crotch panel onto my nose and mouth from the outside of the panty.
I made multiple short, sharp inhales directly out of the apex of the crotch pad whilst simultaneously running my tongue across the vaginal geometry of the material – knowing full well that this is where Denise's vagina and pubic hair had been rubbing all day on the inside of her large knickers.
The smell was indeed tangy – Denise's special cocktail of pubic sweat, vaginal tang, urine and some hint of perfume was also in the mix.
Still yet to explore any further, I yearned to eventually move my attentions further to the back of the panty, where Denise had so frankly confessed to me that she had been releasing gas from her bowels directly into undies throughout the day.
It didn't take long.
From consuming all the odour and any flavour from the vaginal section of her underpants, I strategically began to focus just to the rear where my imagination roamed to Denise's puckered anus flexing repeatedly, as the gas forced its way from her body, the cotton underpants both absorbing odour and protecting her outer garments all at once.
I licked the rear area of her panties which would likely have absorbed most of the gas – not exactly knowing, but vaguely hoping I could still taste the remains of her gassy expulsions. My tongue was also swirling of course for any faecal specs dispatched in the process, even though Denise had not left any obvious poo streaks on the white cotton during the day.
"I love watching you enjoy my panties like this!" Denise purred. "It's like you're smelling and tasting my holes directly!"
"Of course, I want to do that too!" I chirped.
"Well my dirty lover – you're in luck! It's your birthday and I've been meaning to tell you – I REALLY need to go to the toilet!" Denise now dropped the ultimate lead-on.
I could only hope that this meant she REALLY needed to go to the toilet.
Number 1?
Hopefully for certain.
