What this guy says is not adding up. I would keep a close eye on this guy. He is pulling a triple shift? You might want to check that out on your own. Check phone and computer records. Trust has breached. He knew what he was doing was wrong otherwise he would have walked up to you and said something like... Oh hey hun, I'm going to come to bed right after I finished these last few sex emails...ya know 'cause I don't want to bother you. These ladies here will help out. You should really thank these ladies when you get a chance. Hey Babe, while your up, could you get me a beer? Hands are full ya know...
