Para sa mga girls... a tried and tested trick for orgasmic BJ's para sa mga jowa ninyo.
I'm not sure kung may Rocketbalm sa Pilipinas (its a balm you buy sa mga sex shop) but a little dab of toothpaste will do the trick hihih.
on the balls of your palm maglagay ng konting toothpaste as in konti lng then rub it sa shaft ni manoy.
tease him a bit. ihipan mo lang (as in yung blow). he will feel a cool sensation then dahan dahan niyo isubo. what the toothpaste does is that it provides that hot/cold sensation tapos because of the toothpaste/balm your mouth will produce more saliva and this will be very pleasurable for him.
Always remember to keep stroking the shaft and to have a rounded pouty mouth when giving him head para di makagat.
And of course dont forget the balls

To stop him from cumming right away. hawakan niyo lang yung nerve sa may shaft. It should delay it for some time.
