Sorry .. long answer .. and little stories.
I'm a pilot and she's a flight attendant, so often our schedules can be complete opposite, or we can be lined up and actually fly trips together (working vacations 😃 ) So we have sex when we can and when we want. It can be 3-4 times a day, or have 20 days in between or 3-4 times a week. All depends. Our record is 27 orgasms in 24 hrs for her, that was just an amazing mind blowing day. Or we can have INSANE nights of sex, that leave sheets bloody from her shredding my back with her nails. The other side of the spectrum. We have the record of going about 2 weeks of not having sex despite being together. And that was wonderful too. It just happened and we both loved it. Just tender weeks of being together and holding each other. Still being nude together etc.. just we were in the mood for being. Or we will masturbate together over the phone if we want. We both tell the other when we cum without the other. So there's secrets. So freeing.
We have a rule between us. If either is extremely horney and the other is not in the mood we WILL have sex or allow the other to please themselves for the pleasure of the other. And that's because we both insanely want to please each other but understand that life gets in the way. And I tell you it so freeing. To be honest its been very rare that either of us has flexed the rule, but has resulted in some crazy sex.
Couple of examples... one night I came home from a very long trip and was exhausted and she was INSANE HORNEY.. I felt so bad but was exhausted. I showered and hoped that would wake me up. It didn't and asked if we could just sleep, she smiled and said she was executing the "rule". Ok lover, I said. I fell asleep while she was sucking me. That didn't stop her she was loving my member. Not sure how it worked but I was hard enough for her, she rode me .. I'm in and out asleep. That wasn't enough, so she swallowed me again after she finished herself, she tells me. I woke up the next morning after being passed out for 11hrs. But anus was sore.. hmm I asked her what happened, she said with a huge grin "oh that was probably the three fingers I had in your ass to get the cum I wanted"
The other was the opposite .. I was home waiting for her (she was on a trip) and we were teasing each other all day! Sexting is fun! Unfortunately her flights were delayed and delayed. When she got home I was crazy horney. She showered and tried, but was exhausted. So she told me to "use my body as you wish.. make sure you cum!" So I was all over her amazing breasts, licking her deep and loving it then I notice she's snoring. What the! So I continue, my attention turns to her tussy. She's relaxed and my tongue went in easy. I'm hard so I grab the lube and start opening her more with my fingers. I slid deep in, and enjoy the warmth and tightness. Eventually I can't hold out and cum deep in her. I pass out. The next morning morning she tells me "you were amazing gentle fucking my ass, thank you! "
So we communicate alot and get what we want! But the frequency is random and we are stupid happy with our sex life. Often we'll ask.. "how's your sex bucket? If low the other knows the other needs something.
