alright, this probably will sound really strange but here goes. i have this fetish about uterus penetration and it turns my boyfriend on too. lately, we've been numbing my cervix with lidocaine injections and then we push small plastic tubing all the way up into the uterus. it has to be pushed pretty hard, and the cervix forms an extremely tight seal around it.

then we put some more lidocaine solution through the tube to numb the entire inside of my uterus. after it's numb we actually pump water into my uterus to expand it. it takes a while, but when we're done it is expanded so much that i literally look about 4 to 5 months pregnant.
