when i am round my mates i always get erections as i really like his mum and her tits are nice and pert, so i get really hard. This causes a serious problem when i stay over and in my shorts and t-shirt (night stuff)cos it's free and it bulges out more. It is hard to cover up especially if she asks me to move for some reason lol and one time i had a huge boner because she was leaning over in a top where i could see her great tits and i couldnt help but look and i didnt notice her look up at me and she noticed both my boner and that i was looking down her top :S, at this point i didnt know i had a boner either, i just felt really horny lol, but instead of saying something she just smiled and giggled a bit and continued bending over cleaning

but then i realised i had a boner and covered it up ( i was in my normal clothes so it wasnt as hard to cover it up). But later i had to wank after this had happened lol. The nice thing is she didn't embarass me by saying something how cool was that? lol
but the main thing i wan tto know is are random boners normal?
