When my lover cums in my mouth I prefer to rest the head of his dick on my tongue with my lips firmly around his shaft as he shoots his load on my tongue as I slowly lick the underside of his glans - his most sensitive area after cumming. That way I can taste his marvelous man-juice as I remain in this position and suck him dry. Depending on the mood, I'll either swallow his load or share it with kisses.
He likes to take my load in his mouth as he frantically sucks and strokes my dick as fast as he can, causing me to shoot down his throat as he swallows it all without breaking his stride. I usually want to share our loads but most times he is greedy - he's definitely a cum slut. After I shoot, I'm so ready to pull out as my head is too sensitive. But he does his best to keep sucking my dick as long as he can after I cum - driving me crazy - in a good way!
Either way, we love taking each others loads!
