It's like asking "Is there too much cheese in this mac&cheese?" It's just not possible. If anything I think all cumshots should be facials.
I think there can be too much cheese in Mac and cheese.
I too get bored of facials. And I agree with the above point about facials being a way of cum dodging a swallow.
I think if a girl did not want to swallow, I would want to cum over her tits if she had them. And then if she was flat, then I'd want to cum on her face just as long as it's not into a condom or towell. Even if she spat, i'd rather she drool on herself.
