I know it may sound a little bit cruel but in the end, he will love you for it once you bring him right back to the next climax.
Try coordinating your movements so your hand and mouth are going up and down in unison.
He might be oblivious, he might be in an orgasm-induced sex coma, but either way, refusing to reciprocate is not OK, and you damn well should tell him so.
Most women do not know this because they act too timidly, too scared, and they lie, boring while wanting passion not knowing how to create it.
That's just bad math.
This works just as well with fellatio as it does with cunnilingus, too.
The most important thing to remember?
If so, suggest a sexy bath or shower together and start with a clean slate.
Neither one of you can read each other's mind during sex, so speak up if there's something that you want that he's not delivering.
For one, I hear they're both exhausting.
Doesn't mean you have to your fingers all the way up there like he's a puppet.
