Make sure u don’t jack off or fucck before that period. Make sure she has on only panties. Make sure the bathroom is far from where y’all gon be fuccking so you don’t have to smell foul odor and get turned off. Keep her mouth on your d1ck for hours on end. Slow fuccking and sucking so she don’t tire out too quickly. And so the time passes quicker. Watch lots of movies together.
