Substitution

Alan would do anything to quit smoking. So when he spots an ad in the paper promising to cure his addiction he figures he has nothing to lose. When he meets Mike, he recieves some special inhalers to use instead. But the inhalers have strange, if not unpleasant, side effects. Little does Alan know how much he'll have to change in order to quit.(Graphic M/M sex, smoking, all characters 18+)
