I'm not quite 18 yet but this is set up that way.

Dad has a small cabin that belonged to his dad and grandfather before him and we sometimes go for a weekend. It's a four hour drive from our house in the city. Recently, dad invited his friend, Jerry, to come along an bring his camera in case we see some wild animals. I don't know when it began but in the morning when I see dad's rod jutting up, I take it and suck it until he cums in my mouth. Often he is totally passive and other times, gets excited, grabs my head and fucks my mouth and throat hard. I love it.

Jerry's cot was nearby (one large room in the cabin) so I had to decide whether to suck off dad or not and decided, why not? I tried to do it quietly but I suspect Jerry saw me doing at least the last part where dad's shot often gags me a bit. I've sucked off dad each morning for the past two days and I noticed Jerry giving me strange glances and smiles, walking around with a cluster in his pants. I suppose I will have to do him to calm him down but I don't want dad to know.
