Mistress Assistant Ch 02

Sally lubed up the dildo that was still wet with her own juices. I laid back more, and she squirted lube on my anus and started massaging my hole. I took my eyes off her big breasts hanging to till my head back in pleasure. I couldn't help but moan in relief, but I remembered to keep it quiet so other girls in the house wouldn't hear.

Sally then slowly poked my arsehole with the dildo; the stimulation felt so good, I was really starting to enjoy myself when Sally moved my hand off my pussy. She got closer and closer and started kissing the inside of my thick thighs whilst massaging my anus; she worked her way up to my pussy and started to give me a fucking good lick up and down my pussy.

She took this moment to insert a finger into my anus; I was in pure bliss. She worked her middle finger in and out of my hole as she lashed my pussy with her tongue swirling over my clit again and again. I couldn't be any more turned on, and my pussy was at its wettest. I was gripping my duvet, enjoying the feelings Sally was giving to me.

Whilst enjoying the licks of my clit, I was longing for my arsehole to be stretched more, and Sally didn't disappoint. She read my body language and knew it was time for my favourite dildo to be inserted; she slowly pushed it against my hole, and it started to accept the head, still warm from its time spent inside Sally. Once in, she returned to eating my pussy, letting me move against the dildo, taking more in.

The pleasure was incredible; it was clear Sally had done this before; she changed how she was licking me, moving from delicate to firm strokes with her tongue. She turned on the vibrations on the dildo, and it sent me to another world.

The room smelt of sex and ass; my own climax was on its way; the feeling of having my ass take this warm, lubed-up, vibing dildo was too good. I let out a moan; my legs started to shake seeing Sally's head working on giving me a good lick, and my ass full of dildo got me going.

"I have to burst....I need to go......I'm gonna cum....ohh...ohhh...ohhh...ahhh." My O hit, and waves of pleasure resonated throughout my body.

I was in complete ecstasy, the pleasure, the relief; my heart was beating so fast, Sally pulled out the dildo and put it on the bedside table; she put her clothes back on.

"Well done! You passed the first training! Next we work on your toilet game." She left my room and closed the door as if all we did was have a casual chat. My mind was whirling with what just took place; I got comfy and drifted off to sleep totally satisfied.

Once again the next morning we interacted as though nothing had happened, which was weird, but at least it wasn't awkward or obvious in front of the other housemates. This was testament to Sally, to be honest, as she was a veteran at playing things cool. Seeing her in the kitchen, my heart did skip a beat, flashing back in my mind to naughtiness the night before. "Work on your toilet game." What could she possibly have in store next?

We made the normal to-be-expected chit-chat, and I got myself some breakfast, got ready, and headed to the uni with Sally ahead of a day full of lectures and tutorials. Although jam-packed, the benefit was we had a free morning the following day.

The lectures and tutorials we had were mentally draining as we started to focus on new aspects of psychology after our recent case study submission. I was absolutely shattered by the time 5 pm came round, and it was already pitch black on our walk back home.

"Why don't we get a takeaway tonight? My treat." Sally suggested, "That's one of the best ideas you've had all year," I joked.

"What do you want?" Sally asked.

"I don't mind; if you're picking up the tab, you should choose what you want." I looked over to Sally as it started to spit rain above us.

"Ok... well, what about an Indian? I've not had a curry in ages, and we can go all out: bhajis, naan, and pilau rice. My go-to is lamb madras." Sally grinned, looking for my approval.

"Yeah, an Indian works for me. I'll have a chicken tikka and poppadoms. There will be plenty for us to share, but order from Raj's; theirs is the best curry in town," I replied, picking up the pace to attempt to beat the rain.

We hurried back, and after drying off and catching up with the other girls, Sally ordered the takeaway, which arrived just after 7 pm.

I got a couple of beers out of the fridge, and we went to town on the takeaway. Sally insisted I try her madras; it was more spicy than my tikka but very tasty and an enjoyable social evening after a very long academic day.

Waking up the next morning so cosy in my duvet, I'd been able to enjoy a relative lie-in; I could have slept for longer, but I could feel a slight stir in my tummy and a fullness in my bowels to empty. I cut a ripe post-curry fart under the covers, dutch ovening myself. It smelt so bad, but I did enjoy it, and it was a sign that I'd be sitting on that toilet very soon.

I got out of bed and chucked on some loungewear to keep me warm in the cold bathroom. I left my room and headed to the bathroom only to find it was occupied by another housemate, Laura, who was getting ready to leave for her lectures. Not a problem; however, I wasn't bursting just yet, so I decided to head downstairs and wait for the rest of the girls to head off; it wouldn't be long before they needed to leave anyway.

I entered the kitchen and saw Sally chatting away to another housemate. "Coffee?" she asked.

"Oooh yes! I need warming up; one sugar, please," I replied and watched on as Sally got to making my coffee and gave it to me as we socialised with the others before they left.

As I was sipping my coffee, I could feel it get to work; there was a growing pressure in my bowels, but it wasn't uncomfortable, and I was enjoying the sensation of holding this poo, knowing the relief I'll have when I get to sit on the toilet. The coffee and curry combined made me feel some pressure that I really had to release; I let go a big fart that made the other girls laugh, but once they could smell it, they covered their noses quick enough.

"Sorry, I need that toilet once Laura's done." I was a little embarrassed by the smell; I didn't mind they could hear it.

"The bigger the arse, the bigger the smell, I guess," teased Sally.

My urge was growing stronger now, and my tummy was urging me to relieve myself; fortunately, time was on my side with the girls about to leave. I heard the bathroom door open, followed by footsteps down the stairs. Laura then poked her head in the kitchen and rounded up the rest of the girls and left our house.

As the front door closed, signalling they had left, I finished the last of my coffee and looked up at Sally. "Right now they have left; I can finally unload." I left the kitchen and made my way up the stairs only to be followed by Sally.

"Erm... before you go, would you let me have a wee first? I'm bursting; I've not been able to go since getting up," Sally desperately asked.

"Sure, no problem," I replied. I didn't mind if she was bursting for a wee; I could take my time to enjoy my impending dump this way.

"Thanks, you're a star. I had to cross my legs waiting for them to leave; you may as well wait here; I won't be long." Sally said as she edged past me and into the bathroom on the right, leaving the door open whilst she dropped her PJ bottoms and got nestled on the toilet.

Seeing her naked thighs exposed on the toilet was a sight to behold, with her bottoms resting at the ankles of her gorgeous legs. Her big thighs and ass were coming over the sides of the loo seat. The look on her face when she started to piss made my pussy tingle, I have to admit.

"Oh...I needed this! Thanks for letting me go," Sally said, getting the relief she needed.

"That's okay; I'm sure you would have done the same for me." As I said, this another pre-poo fart escaped my cheeks, making a noise loud enough for Sally to hear over her power piss.

"Sounds like you need to be sat on here ASAP," Sally said, still pissing away.

"Yeah, it's getting more urgent, but don't rush. I'm a big girl; I can hold on," I said with confidence.

I was still admiring the view of Sally sitting on the toilet with her piss still forcefully hitting the water below; hearing her pee was starting to make my bladder twinge. My poo was now pushing against my anus, and I soon found myself crossing my legs. My phat ass needed to be sat on that toilet that Sally was occupying; I was getting jealous of her sitting there and starting to regret letting her go first.

The pressure in my tummy was now getting intense, and I had to fart to relieve the pressure, but my bladder was starting to ache, so I clamped my thighs together. Much to my relief, I could hear Sally's piss start to lose its flow, which gave me some comfort knowing my turn would be soon.

Sally's flow turned to a tinkle, and not a moment too soon, as my poo was knocking at the door. I started to hold my tummy; Sally looked up, seeing my discomfort.

"Sorry," she sympathised.

"It's okay; you were bursting. It's no problem," I replied desperately holding now.

"No, I mean I'm sorry," Sally said.

"What do you mean you're sorry?" I asked inquisitively.

"This," Sally said, looking me in the eye, she parted her gorgeous thighs, giving me an eyeful of her pussy but also a big brown tail hanging in the background. It dropped with a huge plop!

"I'm sorry I didn't realise I needed a poo till I sat down, and I couldn't hold it once seated," Sally tried to plead.

I was heartbroken; I thought I was soon to be able to sit down on the toilet to take a much-needed poo, but now I had to wait for Sally to finish hers.

"No way! You said it was just a wee, Sally. I'm close to shitting myself; I held on just for you." There was quite a serious tone to my sentence; I was pissed off.

"I'm really sorry, I couldn't hold this..." Just as Sally said this, another poo started to emerge between her legs; it was a thick cylinder of shit and dropped again, making a big splash. The noises her poo was making splashing into the water were making me more and more desperate, especially when you added her moans of relief into the mix.

"Sally you need to hurry this the fuck up, I can't listen to you go whilst I'm desperstey holding on" I started hopping from one foot to the next.

"Sorry hun, this curry is clearing me out. I'll...uh... Sally said as she passed another turd, it splashed and seemed to let out a lot of softer turds that started plopping in quick succession into the bowl.

I could smell her shit, and it was pungent from the madras she gorged on last night; the sight of her squeezing out this load was getting to me, and hearing the splashes as she relieved herself whilst I was desperately holding on seemed to force my poo, and I soon started to crown. My tummy cramped; this coffee and curry-induced shit wasn't going to hold much longer.

"Sally I'm about to shit myself if you don't hurry!" I was nearly doubled over; this was now a very desperate situation; I was so close to filling my knickers.

"Hold on, babe, I'm nearly done!" Sally said, releasing a huge, gassy curry fart that filled the room, she started to strain.

My arse was at full capacity; if I had skipped that coffee, I may have fared better, but I was struggling; another turd appeared between her legs, and I couldn't last any longer. "I'm going to shit; I can't hold on," I desperately moaned.

My poo crowned and pushed out of my asshole. "Fuck, I'm going...oh!" A wide poo emerged and hit the fabric of my thong; the resistance caused me to pinch off the loaf, and this stinking poo nugget tumbled out of my shorts leg and onto the bathroom floor.

"Oh babe, hold on if you can!" Sally shouted in a concerned tone. I was on the verge of shitting myself badly, and more poo was ready to exit my hole.
