No fantasy, just wonderful body appreciation.
When we were dating, my wife (then girlfriend) let me kiss her whole body with exception of her ass. I could kiss her cheeks, but nothing more. We had a great deal of 69 position sex and my nose was always buried in between her cheeks and resting on her ass hole. One time after she came I just moved my tongue from her clit to her ass. She tried to clamp her ass cheeks tight but my face was between them and my tongue was masterfully running all over her ass hole. My cock was instantly rock hard again and she started sucking and stroking it again. Seeing my reaction, she repositioned herself, opening her ass wider so that I had better access. In no time I came again. From that time I was free to lick her ass anytime we had sex. She loves to have me licking her ass while she uses her vibrator to orgasm. I love that her ass puckers when she comes, as if it is kissing me. There have even been a few times when we are ready for bed when I have asked her that instead of kissing her good night on the lips I wanted to kiss her ass and she has obliged. She pulls her pajama bottom down, kneels on the bed, spreads her ass cheeks and lets me kiss and lick for a few minutes.
I love sucking tits. If I could, I would lick an suck my wife's tits all day. I have made my cum only from licking and sucking her nipples. Having access to my wife's tits, both with hand and mouth, is a must any time that we have sex as well as if she is giving me a blowjob. I love eating my wife's pussy during sex. Performing oral on my wife is often part of our foreplay. Several times I have surprised my wife by spontaneously going down on her in the kitchen or on the chesterfield and eating her until she came. My wife has made it very clear that, other than fingers or my cock, her ass is off limits.
