Expansion Rp 2 (NSFW)

Please read
 
Backstory:  
I want a mare to conduct expansive experiments on and I can make objects appear and change the setting. I want to conduct the experiments because I want to test new expansion techniques. I can use magic to create objects and a control panel to change the setting.  
I get in contact with the test subjects through a newspaper ad
 
Setting: The lab is white and mostly linoleum with beakers, pumps, and a blue portal to the limitless room
 
Rules: No Sonic the Hedgehog themed accounts
 
More than one mare is allowed, as that equals more fun
 
I am to do the expanding unless the mare is a unicorn/alicorn in which case she can expand herself
 
 
only breast, belly, plot expansion, weight gain, or inflation
 
The setting I choose for the RP is permanent. Nobody is allowed to leave it.
 
Users should not attempt to derail the thread or any activities currently going on
