Even for girls who are more sensitive than others, it seems to be difficult for them to come to orgasm just by masturbating their nipples. - One day, a girl whose lower body was aching from nipple masturbation put a pillow on the bed between her legs. - Then...the stimulation given to her nipples was transmitted to the core of her body, and it seemed that the object between her legs was making her pussy twitch comfortably! - With nipple play and foot pins with things between their crotches... the girls cum with their "core bodies"!
