[Lovebite]

This movie is also available for rent and purchase on google play and youtube with English subtitles.
Disclaimer though, on google, it isn't nearly as graphic which is a disappointment. I had to get a copy and download the German subtitles then translate them to English and then add them onto the mp4 file to get the full experience. I'd say it's worth the trouble for the birth scene and what few belly scenes there are.
