Not knowing if you have the willpower is part of the thrill… if you go over, then you pull your hands away and you ruin the orgasm. Don’t be afraid to push yourself.
So, having said that, let’s make it worse. You may have a good long edge in the morning each day this weekend, but then, you can ONLY touch while your neighbours are fucking. Get naked, get ready, watch porn and hope they get it on. Playing with your nipples, even humping, but no direct stimulation until it begins. You could even press yourself against the wall, listen intently as you rub and rub. They’re being loud on purpose, they don’t care you can hear, they probably like it.
They just have no idea that the moment they stop, so do you. No more touching till the morning.
