Searching for a story...

Dunno if this is the right place to ask for assistance on finding something, but I will give it a shot. There was an author on DA yearss back by the name of firsttigerhobbes, he wrote like 3 stories then disappeared. Does anyone by chance happen to have those lying around? All I remember is they were based around two girls with cool powers, one who could blow up her chest and the other who could fit anything of any size up her ladyparts. Assistance would be much appreciated!
Also, to any authors I have bugged about writing stuff, I hope I am not a bother to you guys, I really appreciate what you do.
Thanks,
Cal.
