I personally only semi like it with average to smaller dicks, big dicks-NO way!! I had a girlfriend get her poor lil ass hole torn by her boyfriends monster cock, and now she can't even have a finger in her bum! It needed stitches and everything! (I personally enjoy a single digit in there when getting DATY at the same time.
I let my boyfriend partake in it one time, he is so large I pretended I liked it, then he admitted that he liked my tight warm pussy better anyways, so I was quite happy to know that my boyfriends large dick would not be requiring greek all the time. Any time I offered it to clients it was YMMV(based on size), and I def charged an extra price for the discomfort.
