well for the object to use, the widest thing that is at least 12 inch / 30 cm long that can fit in your ass after you got stretched good, and for the pump, well, half the max you can do normaly before to go to bed and max in the morning. of what i did read would be 10 pump before going to sleep and 22 in the morning
you should AT LEAST fuck your anus as said for an hour. longer if you still have some power left in your arms (not carring of your anal feeling, your arms ARE what are to stop you. not your anus
don't care if its painfull or really sore.
is it ok now?
