As you wriggle around inside the woman's underwear drawer, trying to get comfortable, it becomes apparent that your movements are somewhat restricted... but not completely immobile. You can feel the fabric of her panties rubbing against you as she moves, and you soon discover that you have a pretty good view of everything she does when she bends over or sits down. As time passes, you begin to wonder how this new life as a pair of panties will treat you...
"At least my luck didn't end up with me being something worse..." I'd say, not knowing I had somehow spoken aloud, though I was still in the drawer.
The woman's panties rub against you as she goes about her day, occasionally adjusting them or pulling them up when they slip down. As the days turn into weeks and months, your new life begins to take shape. You soon learn that your owner can be quite carefree at times, sitting on the couch all day watching TV with a bowl of chips in her lap. At other times, she's more active, jogging or going to the gym.
