This is part three, I do recommend reading the previous parts first to add to your enjoyment.
It had been a while since my session with Auntie Liz and her beauty therapist. I had wanked myself silly for weeks afterwards with the memories.
However, I had now developed a serious nylon and pee fetish thanks to my Auntie. This also extended to me having a penchant for wearing her nylons and panties whenever possible.
I had been eagerly awaiting her call, but I suspected her new boyfriend was keeping her busy.
I needed to steal some more of her lingerie to wear but it wasn't possible if I wasn't invited round.
In desperation, I waited until mother was out and went through her drawers again. Disappointment. Just sensible unsexy undies.
Mother was a couple of years older than Auntie Suzie and a bit bigger all round. She had been divorced from Dad for a few years now and had just started going out to a few parties. I had never really noticed her clothes before, but I was sure that I had noticed seams in her hosiery last time she went out.
I made it my business to check when she next came back from a nite out.
She came back from one a couple of days later. She was wearing nice high patent sling back shoes and a fairly tight pencil dress which emphasised her curves. Her greying hair was pulled back and piled up in a bun. Her steel rimmed spectacles made her look quite stern.
I tried to get behind her to check out her legs. She was a bit tipsy and tottered around on her high heels.
"What are you doing?" she snapped as I tried to get behind her.
"Nothing" I stammered, as I managed to glance her Cuban heeled seams.
The trouble is they were probably tights. I had been unable to find any saucy underwear in my searches of her room.
"Well get out of the way, I'm bursting for the loo." she said.
She clacked down the hallway in to the bathroom and slammed the door.
I had a surge of madness and ran down the hall after her. I dropped to my knees and pressed my eye to the keyhole. I was just in time to see her hitching her dress up, pull her panties to her knees and slump on to the toilet. I couldn't quite see her pee from my vantage point but I could clearly hear her forceful jet hitting the water as she gasped with relief. And, even better, they were proper nylons with a black six strap suspenders belt. To my shame I could feel that my cock was now rock hard! I had become fully aroused watching my own mother pissing in her nylons. I saw her stand up and start to wipe with tissue, so I jumped up and hurried down the hall in to my bedroom.
I got in to bed and heard her heels clicking down the hall to her room.
I lay in bed and furiously wanked my still stiff cock, I came with extraordinary intensity, spunk all over the bed sheets and afterwards, I lay in my sticky mess vowing to myself to find mothers underwear.
Next day when she went to work, I went to her room and looked through every cupboard and drawer, but, no joy. I was about to give up when I spotted a suitcase under the bed. I pulled it out and popped the lid. Jackpot! It was full of neatly folded lingerie, stockings and even a few sex toys. I was strangely aroused again.
I carefully removed a suspenders belt, panties and tan nylons from the bottom of the case, hoping that she wouldn't notice these.
I spent the next few days wearing these around the house under my clothes. I must have wanked off a pint of spunk, reliving my keyhole escapade.
The next night, she went out again.
Later, I heard her stagger in, I could tell by the noise she made that she was a bit tipsy again.
She clattered along the hall in to the bathroom. I was in bed wearing her underwear.
Again, madness came over me and I leapt out of bed, ran along the hallway and knelt by the door. Once again I could see her. She was wearing a shorter red flared pleated skirt and matching high heel courts, but best of all tan nylons with wide welts held up by a white suspenders belt and white lacy thong. Her thong was taught across her knees, just big enough to block my view of her pee stream. It was driving me mad with frustration. I pushed my face closer against the door in an effort to see more. At this point the door burst open and I tumbled in to the room falling face first by her feet. I was still wearing her underwear.
"What the hell are you doing?" She shouted. She jumped up mid stream and some of her pee spattered on to my face. This didn't help my already over excited predicament.
She sat back down. "Stand up" she ordered. I sheepishly stood and quickly licked a few pee drops from my face. Ummm, even from those drops, her nectar tasted slightly of alcohol from her night out.
I was now stood trembling in front of my mother with my still erect cock bouncing out from behind her panties framed by her now laddered nylons.
"Now I know where my panties have been disappearing," she said. "You had better explain yourself."
