The slave had trained preparing this session (look at Asstraining preparing 1-arm-fisting), so I penetrated the ass of my slave, starting with my whole hand! After that I went in with a part of my arm. This time I went up to a part of my forearm, so this is one step foreward onto the way to the aim fisting with both hands at the same time. Till then this is together with part 1 my video of first choice about this subject.
