A two-pronged plan for female domination.

Ash and his ladies all get dressed.

It is the off-season, so the Interns coming in the next day can take over for Nurse Joy.

Jessie makes up a disguise so that she can travel with the others to the next Town.
En route, she works on some chemicals to help out there...

Nurse Joy takes Ash to the local Center, explaining to the second Nurse Joy that she needed to consult with him.

While she makes up excuses, Ash pops out Hypno for her return....

At the nearby Beach, a disguised Jessie spots a number of Trainers relaxing.
Officer Jenny is there too, pretending to do her official duties.

She specifically spots Misty and Lili.

In her guise as Staff, she spikes their (virgin) drinks with some drugs to make them hot and horny.
This will make them loose enough for her Master.

She watches the drugs take effect and make them a bit hornier, as seen by them pressing their tits together for a selfie...

The drugs should also make them more suggestible.
She can get them ready and then take them to a Hotel for her Master to enjoy!
