Tifa & Aerith Valentine's Kiss LEWD Ending Page 13 (NSFW) (Patreon)

Here is page 13 of the LEWD ending. It turned out to not quite be the last page. 

Tifa continues to round out, her nipples puffed out and her belly button turned in to an outie. Aerith then thinks Tifa has had enough helium for now and turns off the helium flow. Aerith secures the floating blimp Tifa, so she doesn't float away with the helium tank.
