the first bj i got i came in about a minute. but after that i was fine for 30-40 mins. but lately i havnt been able to finish because the women gets to tired after about 4 or 5 hours. women, pfh, no stamina at all. o well i enjoy it and so do they. one time i went from 3 am to about noon and never finished. needless to say she was a little disapointed not being able to get me off in that time but she loved it.
