Yes

Not wanting to take any chances, you decide to take off your mom, though you remember how you can cut some corners. Pulling off your breasts, you unzip your back, easily taking off your mom without peeling her off bit by bit. Finally out of the deflated suit of your mom. You point the calculator at it and hit enter, causing a bright flash of light to burst from her.

Regaining sight, your look to see your mom suit had gotten an upgrade, but due to being deflated, you can't tell by how much, so to remedy this you open her back and slide her on. The moment your legs are inside of the suit's, you can tell that they gained your sister's muscles, but merged your mom and sister's asses together, and that its the same with the torso because the suits boobs grew at least three cups! Happy with this result, you slide your head into the neck of the suit and close your eyes before reopening them with suit's eyelids. Making sure the breasts are correctly placed over the zipper, you walk over to the mirror.

Looking back is a female athlete, with a sixpack, a plump ass, thighs that could crush steel, two tree trunks for arms, and a face that could turn women lesbian. And even though your new body is stark naked, your breasts seem to levitate as if you were wearing an invisible bra. Seeing this beauty mimic your every move, you start to rub your now wet slit, and are surprised to feel the intensity turned up. Yelping, you realize how your voice has also changed, and that nobody in your family would be able to tell who you are now. Chuckling at this revelation, you ponder what to do next, still rubbing your tits.
