Hi I'm a married guy with a great looking slim wife which we regularly fuck but I hold a terrible secret from her

If only my wife knew I use large butt plugs and dildos
If only she knew I swallow my own cum
If only she knew I had my ass eaten and fingered by a older married guy once
If only she knew I sucked a big cock a few years ago
If only she knew I long to be fucked by well hung guy while sucking another and swallowing load

I know this isn't right and I feel guilty over it .

I have on so many occasions during sex almost let out this secret to her but stop myself at the last minute as I know this would end our marriage
