In between Christmas and new Year last year, my wife and I visited her dad, Barry. He's divorced from my wife's mum, so his small flat just about accommodates us. We all had a fair bit to drink one night, but myself and Barry carried on drinking as my wife went to bed. I must have fallen asleep sat in the armchair and awoke feeling my cock being sucked. Not opening my eyes, I automatically believed it to be my wife sucking my dick, so held her head and forced her to suck my dick deeper down her throat, keeping my eyes closed. The blow job, which was one of, if not the best I'd ever experienced, went on for a good ten minutes and I kept my eyes closed throughout. Only when I started to cum, did I open my eyes and I got a blurry look at the top of my father in laws head. Too late to stop, I came in his mouth and watched as he expertly swallowed the lot. Literally moments after he lifted off my cock and I'd pulled my comfy shorts back up, we both heard my wife getting up. He'd just about sat back down on the couch, when his daughter walked in and asked who'd been moaning. We both lied and said the tv had been showing a raunchy film. She looked at us both and then at the tv which was blank, and sighed. She said nothing more and didn't the rest of our two day stay. She did however tentatively tell me when we got home the reason her mum and dad split up. It was because her mum found her husband sucking off a teenager in their home. Even though we've seen her father a lot this year, nothing has changed in their relationship and still nothing has been said by any of us. Well not until a week ago. We're apparently staying over at her dads new home in between Christmas and New year again. It's a house with three bedrooms and we've been given the back guest bedroom. Which in itself is no big deal. Not until you factor in something my wife said last week. My wife out of nowhere said "If you and dad want to enjoy, you know, I won't hear you this time, not from the back bedroom". I didn't answer my wife, but I did go bright red. Now I have to decide if Barry wants to suck on my dick again, am I going to let him. Because believe me, he certainly sucks cock far far better than his daughter.
