When your sexy neighbor first moved in, there was a party thrown in her honor. Instead of being polite and gracious at the party, she ended up informing your wife that she WOULD be fucking you at some point. Fast forward a couple of months later, your wife is out of town and your neighbor stops by. The two of you end up fucking, obviously. You almost get away with it until your wife walks in the door while your neighbor is still half naked. Oops!
