I was talking with my brother about the weirdest places to have sex and he said he always wanted to try it in our grand-parent's living room, when I asked him why he said because it's very risky and also because if we get caught, the all family will know almost at the same time. So I asked him if he wanna try it when our grand-parents were outside doing the garden in the morning. This was what happen. It was close, after a few minutes I went to the bathroom and my brother went to his bedroom they came home.
