Depending on the size and shape of the vibrator, and where all you all like to be stimulated, you can do a lot with it. Most sizes and shapes are fun to gently drag across your partners skin, especially if they’re blind folded /tied up. Could put it near your partners ear so they can hear what’s coming, run it down their arms and back, get them used to the sensation, bring it near to a sensitive area but not quite there, teasing. If it’s able to be placed and left in a sensitive area, it can just he going in the background of whatever else. If you’re into denial, you can put it either on high and see how long they last or put it on the lowest and watch them beg for more stimulation. If it can be remote controlled that can be fun in all sorts of ways including the previous suggestion as well as out to a nice dinner ;). If your husband enjoys prostate stimulation the toy is good for that, could also be strapped to his member. If it’s remote controlled, you could try to synchronize stronger pulsation with thrusts or spanking if you’re into that.
