A month before my wedding, my fiancée told me she mistakenly left her favorite hoodie at her sister's apartment and asked me to go get it.
I knocked on the door and her sister answered, wearing yoga pants and a low-cut top. I'd always thought my fiancée's sister was hot but she was exceptionally sexy today. Her hair was still wet from a shower and when she gave me a hug I could smell the incredible lotion she always used.
She brought out the hoodie for me and as I was about to turn and leave she said "What's your hurry?"
I replied, "no hurry, just wanted to let you get back to whatever you were doing."
She said, "I know you're about to marry my sister, but I need you to know I think you're super hot, and I've always wanted to have sex with you. If you want to have a last little bit of fun before you walk down that aisle, it will stay between us forever."
Without saying a word I turned and bolted for the door as fast as I could, making a bee line for my car.
As I approached the car, I see my fiancée and her parents standing there with huge smiles on their faces. Her dad immediately said, "son, you just passed a pretty hard test there and I want you to know how happy I am to see my daughter marry such an upstanding young man."
The sister was now walking up from behind and she said, "I have to hand it to you there; I didn't think you'd turn me down."
I was dumbfounded. We all hugged and went out for dinner.
And the moral of the story is: Always keep your condoms in your glove compartment.
