Custom: You set a timer/alarm on your phone, and tell us that this controls when we cum today. You start teasing us by stripping down into a tiny outfit, maybe starting from wearing quite a few items of clothing. You say we are only allowed to cum within an allotted time, starting from the moment you begin to strip, and ending when the timer goes off. The only problem is, we don't know when the timer will go off so we are faced with a dilemna: do we wait until you are almost naked, and risk the timer going off before we get to cum, or have to cum before seeing you really stripped down??
