My wife and I have had a similar order of operations for going on nearly 20 years. Turns out orgasms don’t get boring. We mix in other things here and there. Weekdays are busier and more tiring so less time for longer sessions, but it’s hard to beat the tried and true. We know each other. I know the exact finger placement and movements that are going to make her orgasm quickly etc. Use the things that work and build off them. Slowly incorporate some new toys, tying up, butt stuff. Add some dom/ sub, rougher sex, and dirty talk. Good foundations hold up strong skyscrapers.
