Wife prefers it inside her, and that's usually where it goes since it takes considerable effort to time the whole pulling out thing right
I prefer to shoot it ON her though, because I think its hot as hell to watch it shoot out all over her face or her tits or her ass, and she's fine with it just as long as I clean up the mess I made
Her least favorite place is the mouth, she doesn't like the taste, she'll do it but has to spit it out soon after. Since I'd rather "ruin her makeup" as she puts it
I rarely finish there, unless we're somewhere where she can't easily clean up like in the car
