BBBJ is just sucking a dick. Cock worship is a whole other thing!
You have to enjoy it, genuinely, or it won't ever be highly seductive, of quality or a good sucking period. Cock worship should be exactly that. Enjoyed by the person doing it, letting the tongue travel over the entire area not just the Cock, but also the balls, around the base of the shaft, the peritineum area and even the anus if desired.
Your hands, breasts and eyes should also be used and attentively involved in the entire act not just your mouth. There should be lots of sexy and flirty eye contact and the occasional mischievous smile when coming up teasing the head of a Cock with your tongue.
Use your breasts to keep cock steady or lift back up to your mouth after travelling down south a while instead of your hands all the time. Be creative, seduce the entire area as well as the gentleman's mind and visual senses all at once. When he comes in your mouth, smile and show it to him slightly opening your mouth then swallow and open again ending with a smile. Prove it.
A BBBJ is just that, but Cock worship has a much longer erotic definition.
