Hourglass Inflation

Lungpower Linda starts her training program for the summer inflation olympics. This year she's experimenting with a milk pump to enlarge her breasts. It's an arduous process which is expected to take many days of hard work. Thanks to AshyPie for the milk inflation hints. 

Gloria and Sumia happen to be best friends who often hang out when they're not busy at work. For Gloria, it's a chance to relax and have fun, while Sumia can engage in body inflation-based shenanigans without having to worry about being seen. It's a good thing they have a private area near their apartment, too, complete with a pool to swim in should they desire!
