father knows best

My boyfriend's dad was going out for the night, so I headed over there to take advantage. After his father said good-bye, we ran right upstairs and got down to business. We were being extra loud—just because we could—when all of a sudden, we heard my guy's dad yell, 'Please come down here right now!' We did as we were told and found him sitting at the kitchen table. Apparently, he hadn't left when we thought he had, and he'd heard everything. He lectured us for an hour about types of protection and asked what our preferred methods were. I still can't look him in the eye, knowing that he is privy to such intimate details of my love life.
