Your an ott of many forms, yes? So I pose this question:
Preg Ott Pooltoy?
Do you accept? This form does have the downsides of, well, being a pool toy, meaning you can't move with great dexterity, and are further restricted by the belly being very puffed and very preg. As well as other downsides.
Bonus points if you wanna be hyper preg, it is doable.
