If you're hitting a chick Doggy-Style and you're gonna smack her ass, have the palm of your hand along with your 4 fingers hit right on the ass, but keep your thumb off to the side so it smacks her asshole; I recommend it.
I'm guessing this is before you stick your one eyed monster inside her hoochie? Because I'm trying to play it out as if I was doing it right now and that would be one awkward angled smack if your trying to get your thumb to touch her dirt star. If it were me, I feel like the smack would be more on the side of her ass then anything. Maybe I'm wrong, I'll try it out soon
I spank my woman 24 7. Like wherever I encounter her, bam she gets a spanking. So I spank while fucking butbi have never spanked her asshole. I really need to try it.
