In this story I'm just trying to change my brother's diapers, it's a surprise for me to see his cock so small, I find it funny and cute to see his little erect cock, it's very hard, it just makes me want to suck it, first I make sure that he hasn't soiled his diapers and then I just want to play with his cute cock, this is so much fun but the bell rings... oh! someone is coming! My little brother cums on my face!
