Wife Has Morning Coffee And Cig With Basement Tennant

We have a basement rental on our property which is downstairs from the lounge, we rent it out to an old man who has been living with us for the last 7 months. My wife always makes coffee every morning. She brings coffee to our bed and takes to his bedside table. I've noticed recently she has been taking a long time downstairs and the one morning I secretly walked down and saw my wife naked. Coffee and cigs on the bedside table. I get so horny every morning standing at the top of the staircase while I can hear him moaning with pleasure as his balls noisily slap against her butthole.

I'm sure they can hear me moaning with pleasure. while I masturbate. I feel so guilty enjoying listening to my wife having an orgasm. He has moved away and now everything is back to normal.
