Shizune’s anal ○○ was steadily evolving.
A dimly lit gym storage room. Shizune hung by her hands, in a humiliating position.
Her legs were also bound, leaving her body suspended in the air.
Liquid was injected one after another into her wide-open, fully exposed anus,
and as the liquid reached her sigmoid colon, it swelled her rectum as well, before a foreign object was finally thrust inside.
Her nipples harden at the unfamiliar sensation of her anus being forced open and torn apart,
and she reaches climax again and again, streaming with tears and drool.
Her anus, once like a bud, transforms into a wide, vertical slit—more erotic than a pussy—and the procedure is complete.
