Indian dildo

When a man poops into a females vagina leaving a nice long, girthy log. The female then goes on to use said humongous turd as a makeshift dildo.

Gynaecologist : “Why is your vagina filled to the brim with shit?!”
Girl: “Oh, I did the Indian dildo last night with my boyfriend. It was wonderful!”
Gynaecologist: “Oh hell nah!”
