My [24] wife plays with her bwc vibrator while I [24] worship her pussy

For starters I am a long time reader and first time poster to this sub Reddit.

My wife is 24, brunette with an athletic build and an amazing ass. About 4 years ago I bought her a vibrator with multiple settings for intenseness. She wasn’t a fan of it at first but it slowly became her favorite way to reach an orgasm in bed and a highlight of our sex lives. Fast forward 3 years and I had developed a slight cuck fetish that she is mostly unaware of. While the red vibrator was great I really wanted to see her use another cock so I purchased her a bwc vibrating dildo to try and ease her into cucking. Nothing makes me cum faster than watching her pleasure herself with it and I love to suck and lick her pussy while she runs and fucks herself with a bwc. Occasionally she will pretend to lick or suck it which drives me insane and makes me cum almost instantly. I’d love to hear for others who do the same or anyone who has any advice for moving forward, Thanks!
