Like you don't already know.
Why don't you look it up online?
I guess if you could do that though, you wouldn't be asking here.
The first is done with your mouth. It really should be called a suck job though, because there's no blowing involved. The second is self explanatory. You just use your hand.
Don't listen to the others and do it right meaning the best way to turn your partner on.
Blow-job - Start by feeling him all over, then kiss the end and squeeze it to see if any cum is already to come out. Then put it slowly in your mouth, keeping it very wet. Run your tongue up and down the underside. Suck gently and passionately but don't move your head too much. When he comes don't stop just swallow it. IT will take several seconds for him to stop. Massage it gently with your tongueand cheeks against the roof of the mouth until you are certain all the cum has come out.
Handjobs are fun. You can use lotion but your saliva is best as a lube. Do it gently and rub the underside. Milk it frequently to get any cum out that will make additional lube. When he gets into the rhythm and may come soon put the end in your mouth and catch the cum in your mouth. This way it won't get on him and you can taste it. Milk all the rest out after he is soft to make sure there is none that will mess up his underwear. Kiss the head one last time before ending the session.
u put it in ur bum and shit all over his silly little dick then put it in ur mouth and suck the cum right out of his cock.and a handjob is best enjoyed when u do it urself:)
