i remember when i was about 14 i decided to crack a sneaky wank in my room, i didnt want to be disturbed so i decided in my wisdom to pretend i wasnt home by turning my bedroom light off. i dropped my kecks and jeans and started bashing one out, i heard steps outside my door and just about managed to pull my kecks up over my raging hard on.
my mother asked what the hell i was doing to which i replied "trying on these jeans",
"with the light off"? she replied.
"i was saving electricity"
totaly unconvincing.
