after already masturbating the cut guy, at 2:23:12 she pushes back his foreskin on purpose. funny faces in the meanwhile. her actual first attempt is at 2:22:56 but the guy is moving too much. again at 2:23:42
i think there is also a talk about lube at 2:22:28, seems like they are not understanding each other but am not sure what it is about.
