Bernhard Bulling in Soundless Wind Chime (2009)
9 minutes in the movie, Bernhard Bulling is masturbating on his bed. We see his firm butt at first, then his balls in between his legs. We briefly see his hand moving and what appears to be his uncut dick.
12 minutes in the movie, Bernhard Bulling is bottoming with another actor but we don't see much actual nudity.
