Just found a very nice Czech 100% anal 1on1 production released by the Dutch label Sinners in 2002:
3 scenes, all shot in POV or pseudo-POV, no pussy fucking at all - and the cum-shots go in the girls open asshole.
A small let-down is Julie Silvers bts showing her fucker using her pussy to get ready to shoot it off, however. Still, the footage didnt make it into the film.
