My little brother is bigger than me!
I got two brothers. I'm 19, they're 16 and 14. I still live at home while going to school. My folks made a bedroom up for me in the basement, and I got a toilet and open shower in the utility room (also in the basement). I always use the basement shower, my brothers use the main one, usually. During summers, when we use the pool, mom makes us (and our friends) use the bathroom in the basement - to keep from tracking in the water and ruining the floors. (Of course she lets my gf use the main bathroom).
I've walked in on each of my brothers at least once while they were spanking the monkey in the basement shower. The older one (16yo) is a bit bigger than me, say 8.5", (whereas I'm just over 7.5). Of course that's just my guess - I could be off a bit cause I actually didn't MEASURE it with a ruler - just my eyes. Both times I caught him, he just turned around and faced the corner. I did give him a hard time for beating off - as an older brother should. My littlest brother is definately smaller than me - but last time I saw him erect was last summer - and he was probably still growing back then. I would guess that we are all about the same size soft - we see each other peeing all the time.
My brothers have caught me jerkin off in the shower too a few times, so I'm sure they've been taking measurements and mentally comparing me with themselves. Neither have declared themselves bigger than me - yet.
I am comfortable with my size - of course I wish I was even bigger. As far as how I feel seeing that one of my little brothers is bigger than me - I am truly happy for him - but I still wish it was me that was an inch longer!
