First clip I've ever done using FOUR TYPES OF PUMPS!! First I used my automatic aquarium pump to fill up my belly, then when I reached my burst limit (no more air could go in without letting some out) I gave myself a belly rub with massage oil until my taut round belly was nice and shiny. Then I got my little hand pump and filled myself up even MORE until I felt like I couldn't take any more. After my poor belly was pumped up to air with the limit, I got my extractor pump and sucked my belly button into an outie and pumped up my breasts in a suction expanding tool, all at the same time~
