Sex in the stairwell ended in a rescue call for a Russian woman who was left trapped after her head got stuck in the railings — and her lover took off, leaving her naked on the steps.

The woman, 46, and her runaway boyfriend were making out in her apartment stairwell in Lipetsk, Russia, when her head became stuck, the website Digital Spy reported.

Fortunately, a neighbour found the naked woman, who couldn't free herself, and called police.
