The slut's mouth is a better hole to use than the cunt. As you point out, she can stimulate my cock with her tongue. Also, with her nose buried in my pubes she will smell my manliness. Finally, she we taste me when I cum on her tongue and literally eat me when she swallows my cum. Plus, if you do it right, fucking a woman's mouth can be very degrading. I like to look at pussy. I love licking pussy! But I want to cum in her mouth.
