You really have trawled through the underbelly of the internet, haven't you? I thought no-one would make it to this page. But I thought wrong. Congratulations, you smut-crazed Elvis-loving freak.
Sadly, all that remains are these blurred stills. (from the titles: Jailhouse Cock, Swallow That Cream, Hairy Clambake)
If you have a copy of any of these films, please get in touch. You may need help.
