Way back when i was 10, my mom was pregnant and when her tummy had started bulging out, i remember she'd been 4 and 2/2 months, my p**** would get hard, it was summer when it happened, this one morning, i was already in my speedo and had a large beach towel wrapped around me, i went to let my mom know that I was going over to a friend's house to swim in his back yard pool down the street and she said yes, then as she hugged me goodby, her tummy touched me and my p**** suddenly got hard in my speedo, that was when i'd run to my room so fast that i forgot to close my door, then my mom had asked with a smiles on her face 'is your p**** bothering you sweety?' i'd said 'kind of' she'd asked 'do you feel like swimming with your friend today?' i had said 'not exactly' then she had asked me with her smile 'do you want to see my tummy? may be that's what's making your p**** bother you? i'd said 'yes' then she had taken her top off, oh wow, her slim legs, her little short shorts stretched over her basketball size tummy, which i could see very little of between the top of her shorts and her bra, then she invited me to huge and feel her tummy, she'd asked how my p**** felt, i had said it had still bothered me, then she'd said 'it's okay sweety, you're a boy, this can happen, you can't help it, sometimes your p**** will bother you.' after a while, i just barely had gotten over it.
