Licking Her Asshole

I’ve had a fantasy for ages of licking my wife’s asshole. The taboo, the submission shed show of letting me have all of her, the complete putting aside the strict Catholic upbringing she had.
She recently let me try, and I loved it. Tight and hot and forbidden, dragging my flattened tongue across her asshole then drawing rings around it with the tip of my tongue.
Now she enjoys it enough that it’s an every week or so thing, and all I have to do is join her in the shower and growl at her to spread for me, and she’s happily bending over and reaching back to pull her cheeks wide. We both enjoy me licking her hot tight asshole and we both love the fierce fucking I always give her right after. She climaxes shuddering and moaning and I pump a nice big load deep inside her. The last few times Sue’s gotten comfortable enough with it to pull me around and make out with me again after she’s been filled
