Co-worker said he had sex with his cousin in a barn growing up

The lunch topic was very interesting today. My co-worker said living in northern Michigan had its limits on available women. Him and his brother were around 14 or 15 at the time. He said the party ended when the girl's mom caught his brother and her in the barn naked.

ETA: I would also like to mention that my co-worker sharted in his pants after lunch. The first time I've ever seen him run was today and it was to the bathroom.

He won't be my co-worker for much longer since I'm moving in a few weeks.
