With your lovely wife

Both you and your wife were open with one another sexually. She'd come into the relationship quite the innocent virgin, but once you both had finished college, bought a house of your own, and had all the privacy you'd ever dreamed of, she'd bloomed into just as perverted as you. There'd been times where if not for cooler heads prevailing mid-coitus, you would be living with your pervert of a wife and multiple children. Nevertheless, your request as you both lay on the couch together tonight seemed to have her baffled.

"So you want my butt on your face, and uh, then what...?" She asked you. "I'd be scared you can't breath."

Your wife had, amongst her amazing other traits such as being a lovely woman, the best cook you knew, a passionate kisser, probably one of the fattest asses of any girl you'd ever been with. It was your perfect mixture of thickness, bounciness, and just a bit of muscle; the sheer size of it made it hard to look away. Melissa, ever the innocent girl, kept it hidden under loose pants and flowing dresses.

Not when you were home, however, and certainly not as your hand was grabbing her ass roughly, or doing anal (a favorite of hers).

Lost in your daydream, your wife spoke up once again, giggling.

"Still with me honey?"
