When My Parts Grew

When puberty started thing in my pants really changed in size. I was 13 when puberty really started. By the time I was 14 my balls became massive. Like they were low hangers and huge. Big surprise to me and big surprise to my mom who bought my underwear. I told my mom one evening I need new underwear. She asked what’s wrong with my current underwear and I told her they are kinda tight. I was wearing just my underwear when I asked her for new ones. She turned around the looked down and noticed. She said I’ll get you some new ones tomorrow.

So I moved up a size to boys xl tighty whities.

Then between the ages of 14 to 16 my penis grew. I remember I was 16 and my underwear were tight again. I figured maybe it was normal but my mom noticed me one night going to bed and told me she’d switch me to adult size briefs tomorrow.

I came home from school that day after track practice and my mom had me put on my new briefs after I showered. They were men’s small, 30 to 32 waist. I was only a 29 waist but the briefs fit. They were a tad baggy but my mom said you’ll grow into them and they will shrink some more.

But only then did my mom realize I was pa king a good amount in my briefs. My balls were huge and low hangers. My penis was a good solid 8.5 inches and thick. She asked if I grew a lot down there and I said yes I have. She then informed me my dad was 9 inches long when erect. My dad died when I was little. She told me he wore white briefs because he needed underwear to hold and support everything.

Finally I just pulled my waistband down and let everything flop out. My mom said oh yes you definitely like your dad. There I was, a skinny 130 pound guy with huge balls and a big cock.

By the time I was 17 I was at 9 inches. When soft I was like 5 inches. Definitely a great bulge in my briefs! But when I got hard in my briefs it was definitely a sight.
