Not Fitting So Well (Shortie) (Patreon)

It's SpicyChaiKitten's birthday today, and I wanted to whip her up a little thing (effectively a story sketch) n.n So her sona, Chai, is shopping for new bras when she suddenly... needs a bigger size o.o; Oh, and Sienna is there!

This story contains breast expansion, lactation and (one might guess) partial nudity

Since this is a super short story, it'll go up on FA after a couple days instead of the full month!
