My Best Friend's Crazy Fat Sister Ch. 02

"Um, it's not something I really think about," I said, not comfortable with this conversation.

Zoe sensed my discomfort, and stared at me with her big blue eyes. "Oh sorry, is this conversation about Little Miss Perfect Emily and my whipped brother making you uncomfortable?" Without waiting for my response, Zoe announced abruptly and completely at random, "I'm going to the toilet." She picked up her phone, and walked towards the bathroom on her bare feet.

I should have concentrated on the football, but was immediately consumed by thoughts of Zoe. In a few moments, Zoe would be sitting on the toilet, her jeans and her knickers around her ankles. Collecting a glass and taking it to the kitchen to wash, I heard Zoe close and lock the bathroom door.

Walking extra quiet to avoid detection, I edged closer to the bathroom and was rewarded when I heard the tinkling, splashing sound of Zoe urinating, her pee going into the water of the toilet bowl. My penis got hard at this sound, and when the wonderful sound of her urinating abated I imagined her using cloth toilet paper on her wet pussy, the piss staining the fabric yellow.

My erection throbbed as a series of splashing sounds were audible from the toilet as Zoe emptied her bowels. She stopped pooing for a moment and I thought about what she looked like wiping her poo from her fat bottom. What color was the cloth that was cleaning Zoe's shit away at the moment? I would never know, but could not stop thinking about it.

I heard Zoe fart and once more the sounds of more of her bowel movements going into the toilet were audible, then things went quiet as she presumably wiped her bottom again. I wished I was invisible in the bathroom, being able to see and smell everything she was doing. Zoe had taken her phone with her, was she on it using social media while she was on the toilet? If she was communicating with another person online, did he or she know that Zoe was at this moment sitting on the toilet with her jeans and panties around her ankles as her poo came oozing out of her rectum?

The sounds of Zoe pooing on the toilet continued for close to ten minutes and then were no further sounds of her bowel movements. I heard her flush the toilet and wash her hands, signifying her visit to the toilet was over. I hastily returned to the kitchen so Zoe would not find out I had been loitering in the hallway close to the bathroom, listening to her having a shit.

I probably needn't have worried. When Zoe opened the bathroom door and returned to the living room, she was completely absorbed by her phone and I might as well have been invisible. Thinking about the toilet so much had made me feel the urge to pee, and as I went into the bathroom and closed the door, the lingering smell of Zoe's poo immediately filled my nostrils.

The scent of Zoe's shit was stronger nearer the toilet, and I sniffed in every molecule. As I lifted the toilet seat, I could feel how warm the plastic was from Zoe's fat bare bottom having sat on it for so long. How I wished I could have been the toilet seat. Getting my hard-on under control so I could pee was not easy, but I finally managed it and was able to have a piss. As I shook and zipped myself up, flushed the toilet and washed my hands, the odor of Zoe's smelly poo still evident, I looked at my reflection in the mirror and pondered about my perversions.

This was not the first time I had heard a girl using the toilet or smelled the aftermath of her bowel movements, but at no stage had this ever turned me on in the slightest. One time I had gone to the bathroom when I was over at Adam and Emily's and Emily had been to the toilet immediately before this. I discovered that the ultra-healthy food that health and fitness fanatic Emily put into her mouth wasn't so pleasant when it came out the other end of the pretty brunette's digestive system and into the toilet bowl. But smelling Emily's poo was definitely not sexually stimulating, in fact the opposite. So why was I so excited by the poo smell that lingered from Zoe using the loo? Maybe because it was so private, and something I wasn't supposed to smell? I was perplexed, even as I inhaled Zoe's toilet smell.

On the toilet cistern sat Zoe's plastic container with her reusable toilet paper, and I noticed that now there were fewer in number than yesterday. I reached over, again my conscience telling me I shouldn't and looked at the remaining cloths in the container. I picked up one of the squares of cut up towel and felt how soft the pink fabric was. Evidently one of the towels Zoe had cut up to use as her toilet paper was a beach towel, and the square of blue cloth had a large smiling sun on it, and I wondered if the sun would be smiling so much when it was used to wipe poo away from Zoe's smelly bottom the next time she went to the toilet. The next two squares of cut up towel were plain white and green respectively, and the next one down was light blue with big white and yellow flowers on it. There was an old brown stain noticeable on this cloth toilet paper square, and I wasn't sure if it came from Zoe's poo or from her period, but the latter seemed more likely. For each square, I imagined Zoe on the toilet with her knickers around her ankles, using it to either clean pee from her vulva or poop from her anus.

I glanced at the blue wet bag next to the toilet and thought about what the reusable cloth toilet paper in there looked like smeared in Zoe's foul-smelling feces or wet from her urine. My curiosity was getting the better of me and I nearly opened the bag, my finger on the zip but lost my nerve at the last minute.

People said Zoe was crazy, and this was probably true. However, I was the one who had spent this Sunday sniffing her bath towel hoping to smell her vagina, fantasizing over her feminine hygiene products and her reusable toilet paper and acting like a voyeur when Zoe went to the toilet, things I would never do with any other woman. Maybe I was the crazy one?

The Sunday continued, and that evening Zoe and I went to get take-away for dinner. At the restaurant, we were waiting for our order, and Zoe was listening to music with ear-phones. She was therefore unable to hear the comments of three young guys sitting nearby, who laughed and said 'what a fatso', another saying that the face got an A plus but the rest of it an F, before the guys whispered that they felt sorry for me, waking up next to such a fat wife every morning.

I of course heard it and probably should have said something, but did not, as I was so exhilarated by how the young men thought Zoe and I were married. As we left the restaurant, I felt on cloud nine thinking about how great it would be if we really were married, because then I could have sex with her. As we sat on the sofa that evening, Zoe barefoot and getting stuck into a big bowl of ice-cream, my cock stirred in my underpants as I imagined her beautiful big body sitting there naked, her vagina in direct contact with the sofa.

Monday morning meant work for me, but obviously not for Zoe. She emerged for the day barefoot still wearing her long pink pajamas, her blonde hair up in pigtails. Normally, an overweight 40-year-old woman should not wear her hair in pigtails, but Zoe was pretty enough to carry it off well, and I thought they made her look hot. Her big bum in her pink pajamas, her panty-lines visible, made her all the more appealing.

Zoe lay down on the couch, watching television and playing with her phone. I happened to glance into the living room, and my eyes bulged at what I saw. Zoe obviously had some problem with an itchy vagina, as I saw her open her legs and scratch her female area through her pajamas and panties.

However, Zoe's itchy pussy problem was obviously not sated by this. Oblivious to my presence, Zoe kept her legs open, but this time slid her hand down the front of her pajama bottoms and into her knickers, giving her cooch a scratch.

My erection bulged as I watched the plump, pigtailed, pajama-clad barefoot girl on my couch withdraw her hand from her crotch and out of her panties and pajamas. Then subconsciously, Zoe sniffed the fingers that had been inside her knickers, before licking them. With her vagina obviously relieved, Zoe returned her attention to the television, completely unaware I had seen this.

It took me several minutes for my hard-on to subside and me to compose myself enough to leave for work. "See you later Zoe, I'll be back around five. If there's anything you need, just call me on my mobile."

"Don't go electrocuting yourself," Zoe called after me.

All day I kept thinking about how the barefoot, pajama-wearing Zoe had put her hands down her panties to scratch her vagina, and then smelled and licked her own fingers. I thought about what Zoe was doing at the house during the day. Was she masturbating, her fingers up her vagina, with pussy juice all over her hands? Was she getting changed out of her pajamas? Was she sitting on the toilet with her knickers around her ankles wiping her arse with cloth toilet paper? My erection kept rising as these thoughts entered my mind, and I had to fight to keep it down and avoid embarrassment.

When I returned at the end of the day, pig-tailed Zoe was still barefoot and wearing her long pink pajamas, as though she had not moved from the couch all day. However, she had been eating a family sized packet of cream biscuits, food I didn't have in the house. So where had she got it from?

"Hi Zoe," I said, walking into the living room.

"Oh hi Sean," said Zoe, looking up from her phone, then picking up a biscuit and eating it.

"Just out of curiosity, where did you get the biscuits?"

Zoe looked at me and shrugged her shoulders. "I went to the supermarket and bought them around lunchtime. Where else did you think I got them?"

"You went to the shop in your pajamas?" I was dumbfounded. I would never think of going out shopping in my boxer shorts, and even if I did, I would probably get arrested.

"Of course, what's wrong with that?" Zoe implored.

"Um, nothing," I said, becoming distracted by something else. One of the buttons on Zoe's pajama top had come undone, and I could see the fair skin of Zoe's plump left breast. Nowhere near her nipple, but that I had seen at least part of one of her tits sent me into raptures, filling my mind's eye and subsequent dreams with images of what Zoe's big bare breasts looked like uncovered and I awoke on Tuesday, my bed covers like a tent around my groin.

*

Zoe did not help my erection problems on Tuesday. She had risen early enough, and had dressed in a tee-shirt way too tight for her, which showed off her plump tummy, her big boobs and the outline of the bra that fought a losing battle to keep her tits in check. On her bottom half, Zoe wore a long floral 1990s style skirt that came down to her ankles. The skirt was way too tight, but good for me as it showed off her fat arse and the lines of her full-brief panties. Her long blonde hair hung loose today, stray strands on Zoe's chubby, beautiful face.

Again, I had found myself getting hard at inopportune times as I thought of Zoe and what she was up to at home. I pulled into one house to commence a job and had to sit in the driver's seat for five minutes, as walking to the door with what looked like a tent in the front of my pants would have created a bad impression, to put it mildly. Another time, I was close to the city crossing a busy road on foot and so distracted by day-dreaming about what Zoe's big bottom looked like naked that I wandered in front of a tram, and only the urgent ringing of the bell alerted me to danger and allowed me to jump off the tram tracks with seconds to spare.

Wednesday morning saw Zoe up and about earlier than me, she had one of her special meetings and had to leave early to catch the train. I watched her walk up the driveway wearing a skirt far too short for a girl of her build, but as this was Zoe, my groin responded accordingly.

Walking into the bathroom to brush my teeth before leaving for work, I stopped short at what lay on the floor. Not her towel as usual, for once Zoe had hung this up to dry properly. It was a pair of her knickers, white full-brief panties with light blue leg and waist elastic lying near the shower.

I felt excited and a bit light-headed as my eyes took in Zoe's cotton panties. My heart pounded as I reached down and with trembling fingers, picked up her knickers from the floor. My conscience was sharply reprimanding me again, but I pushed it aside.

I held out Zoe's big white cotton panties and admired them, my cock rising rapidly. I could see the creamy stains in the double-cotton saddle and feeling the softness of Zoe's undies, raised them to my nose.

What I smelled was one of the best smells in my life. The wonderful, alluring, musty, feminine smell of Zoe's vagina. Finally, I had smelled the pussy of the girl I had had a crush on for the longest time. Also on the crotch were a few small yellow stains, the slightest splashes of urine. I smelled Zoe's dried pee drops and thought it was perfectly reasonable that she had minor piss stains on her panties. Zoe had given birth to two children, so obviously her bladder control might not be quite what it was when she was younger.

I fingered the stained saddle in my fingers then moved my nose to the back of Zoe's pants, smelling the place where her knickers would have gone between the fat cheeks of her over-sized bottom. I sniffed the back panel of Zoe's panties, and what she had said about her cloth toilet paper being superior to regular toilet paper I could believe given how clean she was back there. There was a slight smell of poo-poo where the panties would have made contact with her anus, but nothing significant.

With Zoe's panties in my hand, I wondered what to do with them. I wanted to go and put them in Zoe's dirty clothes hamper and check out her other soiled undies at the same time, but was worried that Zoe might have set this as a test to see if I could be trusted not to fool around with her knickers when alone in the house. Or maybe crazy Zoe just forgot to pick her dirty knickers up from the floor, perhaps the voices in her head were telling her to do something else at the time?

In the end, I put the panties back on the floor where I found them. Zoe would be back before me, and she could pick up her own smelly knickers from the bathroom floor when she went in there. The smell of Zoe's snatch on her panties stayed in my brain all day, causing me again to rise at inopportune times while at work. I could not concentrate, very dangerous for an electrician as one mistake could be the last I ever made. All I could see and smell all day were crazy fat Zoe's dirty white panties.

When I got home, the panties were gone from the bathroom floor and I got ready to go to the local gym for my spin class. As I was ready to leave, Zoe came up to me and said, "Where are you going?"

"To the gym, for a spin class," I replied.

"Oh," said Zoe. Then a smile crossed her pretty face. "Can I come with you, if I change quickly?"

"Sure, I'd love you too," I said.

"Just be a minute then," said Zoe, dashing to her bedroom and emerging wearing a tee-shirt, blue sweat pants and a pair of white sneakers. I drove to the gym, and Zoe and I took our places in the class, Zoe taking the stationary bike in front of me. The other people in the class were fit and slim like me, so the overweight Zoe stood out a bit. Some of the other members of the class looked at her as though they knew her from somewhere, but nobody asked her if she was Zoe Xavier, the once-famous Australian tennis player.

When the spin class commenced, I learned two things. One, it was a bad idea for me to take the bike behind Zoe, as the sight of her fat bum in her sweat pants and her panties showing at the top made it hard to stop getting an erection. Two, despite Zoe having never done a spin class before and me doing them regularly, Zoe was better at it than me.

Although overweight and out of shape, Zoe had no trouble following the instructions given and keeping up, in fact she was probably the best in the class. Perhaps within Zoe's now chubby body still beat the heart of an international athlete? A feeling of inadequacy, a petty almost childish jealousy filled myself on the way home, and it only went away when Zoe went to take a shower to wash her sweaty body clean that I stopped being jealous, and concentrated about thinking about Zoe's fat nudity under my shower.

On Thursday morning, I awoke early to put a load of washing in the machine before work. I was just sorting out my clothes when I saw Zoe come out of her room and walk to the bathroom, barefoot and wearing an over-sized tee-shirt. This was great to me as I checked out Zoe's big tits pressing the front of her tee-shirt, the shape of her big bum noticeable at the back and her legs and bare feet exposed.

The bathroom door closed and locked, and soon there came the sound of Zoe's pee tinkling and splashing into the toilet bowl. There came a few seconds of quiet as Zoe presumably wiped her wet pussy clean of urine, then she farted loudly three times in succession. Zoe's third fart turned into a squelching noise and then there was a massive series of splashes as she defecated, her poo sounding like it was going everywhere in the toilet bowl. Again it was quiet presumably as Zoe wiped her bottom, then came another rush of poo from her bottom, then quiet and finally she made more splashing noises as she pooped again for the third time, this ending with another loud fart from Zoe.

This time all was quiet for a minute or so, then the toilet flushed and Zoe washed her hands, emerging from the bathroom. As Zoe passed by me, adjusting her panties through her tee-shirt she suddenly stopped noticing me for the first time.

I was about to start the washing machine, and Zoe stood looking at me, staring at me with her crazy blue eyes, half-laughing and half-annoyed.

"Hi Zoe," I said.

Zoe stared back at me. "Are you doing the washing, Sean?"

It seemed pretty fucking obvious, but I was not sarcastic in my response. "Yes, that's right."

Zoe looked at me, smiling a crazy smile and rolled her eyes. "Sean, how could you even think of doing laundry while I was sitting on the toilet going number twos?"

I couldn't see how my starting a load of washing while Zoe went to the toilet would be a problem, and asked. "Sorry Zoe, is there a problem?"

"Only that I'm running short on clean knickers, and I was going to ask you if I could put my panties in the wash with your clothes this morning," said Zoe. "I nearly missed the chance because you started while I was on the toilet doing my poo-poos."

"Sorry, but it's not too late if you want to ..." I began before Zoe cut me off.

"I'll just go and get my knickers -- I need to wash some of my bras too, don't do anything until I get back," said Zoe. She dashed on her bare feet to her bedroom and returned carrying a number of her cotton full-brief panties and four bras, and I thought how lucky these bras were covering Zoe's big tits all day as she put them in the machine.

Next Zoe put her knickers in with my clothes to get washed. She had several pairs of white knickers including the ones she had left on the bathroom floor yesterday, one pair of pink knickers, one white with blue floral print, one blue with lemon colored leg elastic, the lilac panties Zoe had been wearing on the day she moved in and another a novelty style pair of full-brief panties with cute cartoon animals on the print, similar to one of her cloth period pads in the box in the bathroom although I did not mention this to Zoe for obvious reasons.

One thing all Zoe's panties had in common aside from the fact that all were cotton full-brief panties was that they all had significant snatch stains on the double cotton saddles. I felt my erection rising as I saw the mess Zoe's vagina had made of every pair of her panties, big creamy colored stains. Zoe's cartoon animal panties were the most soiled, I could actually smell her vagina on these and the stains on the soiled saddle were hard. Zoe must have been turned on when she was wearing these to have creamed her cotton panties so much.
