I went round to my fiancee's house the other night. Her sister answered the door in sussies and a low cut bra which was struggling to hold her ample chebs.
"Anne's gone out for a few hours. This is our big chance, the wedding is next week. I've been gagging for it ever since she brought you home. Quick, come upstairs and give me a right good seeing to."
I immediately ran away back out to the car. Seconds later, they were all at the front door, fiancee, mum, dad, the lot. They'd been hiding behind the door the whole time.
"Congratulations" they all shouted. "You've passed our wee test! It's wonderful that our Anne will have such a faithful husband."
Moral of the story - always keep your condoms in the car.
