the logic behind this thread presumably being "animals never ask themselves" or something?
it's not that rare once you let them know you can scratch that itch and certainly not rare enough to warrant a "this one time..." memorable story.
i won't pretend i'm never the horny one or that i don't ever initiate, but still, most of our sessions aren't started by me. they're not even that subtle about it. like "want a back rub?" and try something from there...
my girl just rubs her body against my leg (kinda similarly to what cats do) to grab my attention and then either turns around and pushes her backside into me or goes to the one sofa where we usually do it and climbs on it and waits if i follow and if i don't, she's back to step one.
my boy just grabs my hand and either tries to push me towards his sheath or the ground where he either tries to mount me or just pushes his backside into me (it's when he's lazy and wants me to suck him with no work from him). he doesn't really care that i prefer option one so there are times when we're sort dancing on the floor where he's trying to turn his butt towards me to get me to suck/jerk him off (our sucking position is me sitting behind him, holding his thing turned behind him, simulating a butt to butt tie)while i keep trying to turn and present myself for him to mount and he in turn just grabs my hand and tries to turn me to face him while he also turns again and again which ends when one of us caves in. it's usually me.
