How did you know that I love to feel a man explode all over my tits and throat after a nice sensuous tit fuck. I love the heat of his cum all over me and watching his expression as he explodes. Its fun to be able to offer a man a special treat between my breasts.
As for cumming down my throat, that is a whole different story. I would love to play, and lick, and suck your cock. I think a good way to get to know a man is to play with his cock. Provide a little worshipful service that has him begging for release. Then I slide him deep into my mouth and throat and drain him dry. I'm careful to nurse every drop out of him so he is completely satisfied when he finally slips from my mouth.
So I like both of your ideas, but they are very different experiences. Each should be undertaken separately and enjoyed for the special sensations and pleasures each affords.
