Big Bang Anal AO with my nerd brother's mate

My brother really is the nerdiest nerd around. His mates keep sending him to the petrol station and then suddenly there's a knock on my bedroom door. Normally the guys just want a photo or maybe a little blowjob, but this time the guy really isn't satisfied with anything and takes my little arse cunt AO cold as ice, even though I actually wanted to learn. Of course we have to be quiet so that my parents don't notice and later tell my brother that I'm fucking his friends again. We've had this topic often enough. :D
