i have a hard time cumming with just the females mouth alone on my cock. there just isn't enough action with just the mouth. what gets me every time is the suck 'n jack. she puts two hands on my cock and jacks, at the same time sucking the head with a nice, smooth, rhythmic up and down motion. my god, that feels so unbelievably good. she has me cumming in no time. hopefully we can help. let us know how it goes.
