What are some clues that there may have been or is incest between a brother and sister?

This may sound weird but I kind of feel that the relationship my husband has with his sister is a bit strange. The more I get to know his sister, and the more I am around them both together, the more uncomfortable I feel. I feel that they are too emotionally close for a brother and sister, and while they're not rubbing each others thighs and hooking up, they touch each other in ways I wouldn't touch my brother...
