Contact me at
[email protected] and I'll give you one for free as a promotional deal, but you have to let us bring in clients and you will have to let us show a video of you and your wife fucking for our showroom, plus our demonstrator Kevin will need you to take a video of you and him together so we can have a video to impress or homosexual clients.
