I'm sitting here right now wondering if I've gone too far. My father in law is a complete bastard, yet I found out fairly recently, he enjoys having his mouth filled with cock and adores being fucked.
Having the knowledge, I told him I knew about a guy who'd fucked him (I didn't) and that I wanted my balls drained. Telling me his daughter would hear about it and he'd disinherit her, I basically called him out.
Not only did he suck on my cock like no one has ever sucked on my dick before, but after I became ultra erect, I had him kneel up on his front room rug and fucked him from behind. To make sure he didn't try to make out I was going to be in trouble, I also took a brief video on my phone of my cock sticking out of his asshole, and his face in view.
Since I first fucked him that day, he's been totally different with me, and hasn't been the complete shithead he's always been.
In fact only two days ago we spent the whole afternoon having sex and I must have fucked him in as many positions as I;d ever fucked anyone. I also showed him the small video of me fucking him before. He now says he's true to his family and his daughter, yet he now wants me fucking him all the time.
That's why I think I've gone too far.
