My Greatest Fetish

I have a girlfriend who I have been dating for 5 years. My greatest fetish is the thought of having her get properly fucked by my dad. I mean everything, having her suck his cock, getting titfucked, having him fuck her doggystyle, choked - everything. I haven't told her about it and I probably never will, I doubt she'd be interested. In my fantasy, she'd let him catch her in the shower, or maybe drop a towel, or catch him staring at her tits.

I have seen him sneak peeks at her cleavage and butt when we have all been hanging out, so I am pretty positive that he would jump at the opportunity to fuck her. My biggest fantasy is having a secret camera cathing him use her as a fuckdoll.
