I remember one set of rules a woman had for sex with her. First you horny tongue had to caress every bit of her sexy opens before your cock could make its move. First lick and suck the lips of her mouth. Then your tongue must oil her ass hole with just its tip. Finally ending this introduction part your tongue got to lick and tease just the lips of her pussy. At each stop you had to beg to have you cock cum in her pussy. At each stop she would coyly say you must do her mouth, the rim of her asshole or her pussy lips again before your cock could enter. This teasing could go on and only as she got hornier and hornier. Finally she would yet stick your cock in my cunt not and make me cum.
