Lesbian pissing inside the uterus of other with tube in urethra

Lesbian piss inside the other woman's uterus using a tube inserted into her pee hole until the other woman's cervix. Sadomasochistic games between lesbians inserting screws and threading them into the cervical canal as if it were a thread which produces tremendous pain when turning the edges of the screw inside her however these lesbians get pleasure from painful sadistic play. She inserts tampons into the uterus that, when they widen, stick to the walls and so they can pull the strings of the tampons without them coming out, producing an amazing prolapse of the cervix that the other lesbian takes advantage of to suck and lick. Then they tie the threads of both tampons and facing each other they begin to pull causing the prolapse of the cervix of both women. Finally, a lesbian decide to inject up to 200 ml of a liquid into each other's bladder with a huge syringe using a tube inserted into the pee hole. After having the bladder full, she inserts the end of the tube into the cervix of the other lesbian and then she begins to piss, filling the fallopian tubes and the entire uterus with the mixture of piss and liquid. After urinating, she takes out the tube of her urethra and puts it in her mouth to blow and put the remaining liquid of the tube.
