What's a good way to get a suction kind of feeling ? Either from make-shift household items or an inexpensive toy from online, etc.

One day I'd love to get a good quality one like the Womanizer or Satisfyer,but I can't afford it right now 😭.

I'm hoping somebody out there has experience with a knock off version that is similar ?

(Or even if you have either of the two real ones and can attest to them )
