Being at a male-only school certainly made for a testosterone-charged environment. Outside of lessons, young males think of two things – sport and sex and not necessarily in that order. I played a lot of sport and my physique slowly changed through this intensely hormonal period. Sex consisted entirely of exercising my right hand on my growing manhood.

Now, as a fit sixteen-year-old, I was now about seven-and-a-half inches on a good day and a good six inches round and so could still just meet finger and thumb around it. It was good to get back home for the holidays – back to an environment where women existed, even if they were Auntie Helen (more in another story!) and mother.

When at home, I spent a lot of time keeping fit and this usually meant getting out for a run in the countryside for five or six miles. It was the start of the summer holidays and a very pleasant July morning. I kitted myself up in shorts and a T-shirt and set off for a morning run. It was a beautiful morning and I felt totally relaxed as I ran along.

About forty minutes later, I arrived back home to be greeted by my mother and Helen in the garden. I told her I was just going to have a shower and would be out to join them shortly. Mum shouted back that there was no rush and she would make a pot of tea in about fifteen minutes or so.

I had now got my breath back and cooled down as I headed for the bathroom. I always felt slightly randy after exercise and looked forward to a gentle right-hand session in the shower. My cock was stirring in my shorts at the thought of this. I got to the bathroom, locked the door and stripped of my running gear. My cock stuck out straight begging for attention.

I picked up my sweaty running clothes off the floor and was about to put them in the laundry basket in the corner of the room. I lifted the lid of the basket and discovered it was fairly full but what caught my attention was a pair of white knickers and one of my mother’s girdles on the top. I dropped my running gear back to the floor and picked up and looked at the girdle.

This was the early 1970s and most women in their thirties and forties wore a girdle of some sort. Based on the pages of adverts in the catalogues and women’s magazines, there was a huge choice. I knew my mother wore a girdle all the time, having seen her around the house and thought nothing of it. Before access to men’s adult magazines, I had many times whacked off looking at these adverts – especially in the mail-order catalogues.

My mother favoured the long leg girdles and as I was to learn later she nearly always wore Playtex. I stared at this girdle in front of me and I do not know why but I picked it up to have a good look at it. It felt heavy and supple and seemed to have an interesting smell.

If you have ever closely inspected a Playtex girdle of this era you will know what I mean. It must have been the latex in the stretchy material but that distinctive smell stays with you forever. The white knickers were with them and so I assumed they went together.

While I was looking at these fascinating pieces of underwear my cock had gone from semi-hard to absolutely rigid. It was now pointing straight up and was rock hard. In fact, being uncut, it had grown so hard that the whole of the tip had emerged from my foreskin and was swollen hard and purple.

My cock had grown to a point where the foreskin was stretched out along the shaft. It was so hard that it felt like it had stretched to at least eight-inches and I was so turned on, I could feel my face flushing and waves of pleasure went through me.

What I did next was life changing. Yes, and let’s own up guys, when visiting friends etcetera, we have all looked at knickers in the bathroom laundry, sniffed at the gusset and wanked over them but never tried them on. I looked at the knickers and girdle and wondered what it would be like if I tried them on.

As I tentatively stepped into one leg of the knickers I noted the slight stain in the gusset and stepping into the other leg, I pulled them up over my throbbing rigid cock. I picked up the girdle and one leg at a time I stepped in, pulling it up my legs, and discovered it was actually quite tight. As I pulled the girdle up my cock not only rock hard but ooozing a clear liquid not seen before. When I finally got the girdle on, the front firm satin panel pressed my cock hard against my abdomen. I was surprised at how tight it felt it was but it felt amazingly comfortable!

As the knickers and girdle warmed up on my hot post-run body the distinctive Playtex smell filled my nostrils. I took a deep breath and again felt waves of pleasure flood through me. I was taking deep breaths and rubbed my hand under the crotch pressing the material into my balls. As it warmed up further I got waves of another smell – the smell of a woman. I continued to run my hand over the outside of the cotton gusset that was holding my tight overfilled balls.

When I sniffed at my hand the smell was intoxicating. It was different to my sister’s knicker gussets (samples on several occasions), earthier and stronger. I was smelling my Mother’s pussy as her knickers warmed up through the gusset of her girdle. I took several deep breaths and as I looked in the mirror I could clearly see the outline of my rock hard cock behind that tight satin panel.

Taking deep breaths I was feeling light headed and could feel the blood pumping in my head. As I took another deep breath of her deeply feminine perfume the world went mad! My knees buckled slightly and as my hip thrust involuntarily forward my anal sphincter contracted. The first high pressure spurt of spunk shot from my cock encased in its fabric prison. I must have let out a moan as I grabbed the radiator on the wall for support.

Then a second even bigger shot of cum filled the inside of her knickers and girdle. Then, again and again, each time causing me to groan involuntarily. There were probably seven or eight spurts before things calmed down. I could feel the sticky warm fluid run down the side of my cock and around my balls. It was one of the biggest cums of my life to that point.

Suddenly, I was aware of a knock at the door which brought me back to my senses. Thank god I had locked it. It was my mother asking if I was OK in there. She must have heard the groans.

“Yes, fine,” I replied. “Just doing a few press-ups before my shower."

As I said this, I could feel the warm fluid now running down the inside of the left leg and start to drip on the floor. I knew I produced a lot of spunk but this was in another league. Apart from a very occasional wet dream, I had never cum without touching my cock before. My heart was pounding and my cock was still gently twitching as it started to very slowly shrink.

I peeled the underwear down over my cum soaked cock and down my legs. It was absolutely soaked inside, I had never seen so much. Not sure what to do, I wiped as much as I could off with another couple of pairs of knickers out of the basket and then replaced everything hopefully as I found it and put my running kit on top. I was glowing from top to bottom. I washed off in the shower, got dressed and joined my mother and Auntie Helen for tea on the lawn.

The rest of the day was spent around at a friend’s house. I couldn’t get this morning’s experience out of my mind. What happened, I still could not believe the intensity of it and the pleasure it gave me. We eat fairly late in the summer and I got home about 7:30 in the evening in time for supper, which my mother was preparing in the kitchen.

While she was occupied I crept quietly into the bathroom to have another look at the girdle. My cock was stirring again in my shorts and was filling what little space there was in there. I lifted the lid and horror – the basket was empty! My mother must have washed it all this afternoon.

I got back to the kitchen where my mother was now sitting at the table. Mum turned round to put a pot on the table and then just looked at me. She seemed to be slightly flushed and had a smile on her face.

“I don’t mind you doing press-ups in the bathroom before your shower,” she said and then she added “but next time, don’t do them quite so close to the laundry basket!”

I must have gone beetroot red and yet again was very aware my growing erection filling my shorts as I sat down.

“Yes, mum," I replied and smiled back.

'Had she got off to my semen saturated girdle?' I wondered as my cock involuntarily twitched in my pants.
