Well, my OH really likes this - sometimes instead of giving him an all-out-no-holds-barred BJ, I just spend ages licking him with just the very tip of my tongue, paying loads of attention to the tip and the most sensitive areas there - keeps him hard for ages and really really close to orgasm, and I only let him come when I want him too - he has to beg me, lol...I can actually bring him to orgasm just by doing this - or with a combination of that and my hands on his shaft...
