Under the Christmas Tree
My husband and I were home alone one afternoon in the living room, relaxing and talking about Christmas, how much we loved one another and on and on.
We started making out on the couch and eventually fell onto the floor where we made fantastic love and collapsed in each others arms, cuddling under the light of our Christmas Tree. It was perfect, and we fell asleep.
About...half an hour after we fell asleep my sister walked into the house, no knocking, nothing and saw us on the floor. She shut the door and immediatly left.
I about peed myself I was so embaressed not to mention shocked when woken up.
She had come by to get my hubby and I so we could see her kids perform at the Christmas pagent at the church, so we had to get up and get dressed and join the family to go together.
We havn't talked about it since, but she has never forgotten to knock since.
