I needed a new pair swim trunks, having started a little growth spurt. Mom handed me some cash and told me I could walk to a nearby store and buy them myself. This was the first time I had been allowed to pick my own clothes, a big deal for a twelve year old! Of course I wanted the coolest looking pair I could find. I decided on a style and color, but had to settle for a size just a little too tight. But they fit well enough and looked great, so I bought them.

Of course Mom was less interested in the coolness factor, she wanted to know how they fit. I was told to change into them and let her see. So I went to my room and changed. Mom was sitting on the couch when I came downstairs wearing nothing but my resent purchase.

“They’re too small, come over here” she scolded.

I stood in front of her as she tugged on the waist then at the leg opening.

“They’re too tight in the legs, and I can see this” she said as she gave a little pinch to my cockhead! Seems I failed to tuck it away properly and you could indeed see it’s outline as it was laying straight up from my crotch.

Although I had been jerking off for a year by then and had started to shoot a small load, this was the first time anyone else had touched my dick. A hot, electric flash shot through my body. I couldn’t believe how much better it felt than my own hand. It was more than a little embarrassing to have my mother pinch my dick, but I was so overwhelmed by the feeling that I found some manly courage.
