Graf Dracula's Bissige Saftfotzen (2005)

Parker, a vampire-hunter, sneaks under false pretenses into the castle of count Dracula, to finish the wild orgies. But as he enters the crypt, he gets creeped over by doubts about his mission. The more he fights against these horny vampires, the more he sinks into the suction of this uncontrolled erotic odyssey.
