I love my girlfriend's ass so much and my greatest fantasy would be for her to beg me to lick her a-hole and her bending over, spreading her cheeks for me, and letting me do it. I don't necessarily like the smell much at all, but the act of doing it is so dirty and erotic that it turns me on. I've done it before, but more secretly. I just want to take my time on her and have her greatly enjoy it. Is this normal?
