This is a very uncomfortable situation indeed. You should start by taking responsibility for your actions. Let your little sister know that what she saw was not appropriate for her to see. If she has questions, answer them as simply and appropriately as possible. For example, you could say it's a normal but private activity for adults. After that, work on your self - control and privacy habits to avoid similar incidents in the future. It's important to also respect the fact that this might have an impact on your sister's view of you, so be extra careful in your interactions with her going forward.
