As I was inspecting my wife’s buttcrack tonight I noticed she has a secondary butthole and maybe even a third. Those of you who haven’t checked should ASAP to see if you too have a pilonidal sinus, they can become infected and drain puss down your crack. Medical experts theorize the tunnel forms from excess hair growth and sitting down for long periods of time. I never knew this existed and never knew my wife had one and we’ve been married since 5 years.
