Gawd...as much as it pains me to say this, I agree with sev. Who in their right fucking mind munches a box that your buddy just dropped his load in??? Who sniffs a sock you have blown your cock snot into?? Was it out of curiosity?? Did you much her box while your buddy was in it because you somehow made the rationalization that if your tongue hit his cock its ok because you were originally meaning to lick her snatch?
Wow...next stop, Fagville.....population: YOU
Are you trying to tell me that if you found a crusty, carboard stiff sock at the bottom of your bed you wouldn't give it af furtive sniff? If no, you're a chick or a liar, as all men have to give truly disgusting things a sniff just out of idle curiosity.

Anyways, my second example was purely hypothetical. Imagine you're seventeen and in your second year of sixth form college, and you get invited to a party. You end up getting shitfaced and going to a bedroom with a girl called Davina, for example. One thing leads to another and before you know it you're fingering and eating out her sweaty box, before she gives you a drunken blowjob that is reminiscent of being fellated by a St Bernard, and you shoot your load in a record time.
It is only the next day that you find out that a friend of yours, lets call him Ross, had banged the same drunken slut hours earlier and had shot his muck up her. You are not amused and are severely mocked for this for years to come.
This is how such a situation would arise. All purely hypothetical, of course.
