That’s what I read (and wrote):
“And then there’s this hard-core scene, reportedly starring body builder Pietro Torrisi, who has an uncredited cameo in the movie, and an unknown blonde.”
This info comes from the Nocturno side and is apparently also in that book ‘Wild West Gals’ (Is there a body builder on those pics?)
I’ll see if I can find more info on this Genka girl. Didn’t know her.
