very efficient method to leave a pussy loose and wide for a good fisting. I did the same way with my wife during the first years of our marriage. Currently, after a few years of this practice and two natural births, she is only fully satisfied and has strong orgasm when I'm punching both hands at the same time inside her wide vaginal canal.Her cunt got stretched and very loose by I like it more this way.
my wife love when i strech her pussy to the max...
