What's the ultimate, guaranteed sex trick to get a guy coming back for more???
In a general sense...
a mind numbing blowjob.
a hummer is great because it involves a man's two favorite pasttimes; sex and doing nothing at all.
I thought you'd be more creative than that...
but then again...
1) In that case, can you give me your rough estimation on the percentage of women capable of giving this said mind numbing blow job?
2) Do you think finishing up with the "sucking a golf ball through a hose" technique works best?? ie; sucking for dear life?
