Polish finger trap
When someone inserts one index finger into a woman’s vaginal opening while inserting their other index finger into the anal opening of the same woman. The woman then performs her Kegel exercises while the prey struggles for freedom.
Careful, one finger at a time - otherwise it starts to become a real polish finger trap down there.
The polish finger trap
A man puts his finger in the woman's vagina held in place with a vice. The man keeps it there until his finger nearly looses it's circulation and then they stop.
