My brother and I made a deal a few years back. We both gave maximum priority to our careers so everything else is secondary, relationships, hanging out with friends and family. So our deal is: we must to be available when the other needs sex. We live together mostly because of this. This day I came home very frustrated with my boss and I needed a fuck to relax. When I left work I sent a text message to my brother and when I got home he was already waiting. Believe it or not, this works very well for us. When we are done we both can go back to what is our main priority without wasting time.
