This is a story three pack: Shrinking Behind Schedule, Shrinking Ahead of Schedule, Shrinking on Schedule
 
Shrinking  Behind Schedule synopsis: 
 
Elena works a stressful job for a high-class fashion magazine. The hours are brutal, the workload is heavy. She needs a release from time to time, and alcohol just doesn't cut it . . .

But Elena has a secret . . .

A friend gave her a special little potion that makes her shrink! She loves the feeling of growing smaller, of feeling her clothes slip away, of seeing the world swell around her. The effects take hours, so she drinks the potion at work. By the time she's off the subway and in her apartment, she's less than two-feet tall . . . and still shrinking.

But today, the train has a hiccup, and she's delayed. Now, she's in a crowded place, steadily getting smaller while everyone else rises around her . . .

Shrinking Ahead of Schedule synopsis:
 
After nearly shrinking away on the train, Elena is back to her regular life. As she enjoys her coffee, she bumps into the exotic girl Suki from the train - one of the people to notice the change in Elena's size. Now, Suki talks her new friend into taking the plunge again, so Elena drinks her shrinking potion right there in the coffee shop! The process is slow and arousing, and the more Suki wants to play, the more Elena wants to stay. Will they make it back to the apartment in time before Elena shrinks down to an inch?

Shrinking On Schedule synopsis:
 
Elena and Suki have been seeing each other for a few weeks. Suki gets an allowance of shrinking potions, but it isn't enough - she wants more of Elena. But when an important event forces the girls into an uncomfortable social gathering, she knows that she'll have to give Suki the cold shoulder. But Suki has other plans . . .

If Elena won't talk to her in front of those fancy friends, then maybe a shrinking potion is in order . . .
