Well, it has happened ;-)
I would prefer to have my lover's cum in my throat than my own though :-D
It seems very rare that a male in a TS&man porno combo really takes the load of the girl.... At least lovingly anyway, it seems. I am reminded of a scene with Sapphire - there are two versions, one cut to remove the bit where Sapphire cums into the guys mouth. Damn, that was the best bit, really sexy. But I guess too *much* for some viewers.
