I saw a softporn movie once, I think seventies or beginning eighties… Bit like Emmanuelle, but this one had a weird twist… a guy has sex with 2 women, a blond and a brunette.
The girls take over, and one ‘gives head’, while the other thighten the grip on the guy…. one point, I think the brunette bites in the guys dick… while he is screaming the girls enjoy the blood and enjoy the situation
I have the scene somewhat on tape (only last part), I ‘overtaped’ most of the movie 🙁
Not sure if that movie had other ‘cruel’ scenes in it, or how that scene ended…
