Honestly tittyfucking is just a little boring to me, and I always assumed it was boring for the guys too... I only get 1-2 inches of cock in my mouth at a given time, my tits aren't super huge so I always have to do the thing where my hand wraps around to hold the cock in there too.
I prefer sucking dick much much more. I get really spitty when I am properly throatfucked first anyway.
