My busty girlfriend was drugged and assaulted by delinquents until her sperm flowed backwards. She got an erection from seeing drugged sex positions. (Fujimori Riho PPPE-178)

I successfully confessed to the classmate I'd always liked and suffered with, and she became my important girlfriend. But unexpectedly, she was gang-raped by a group of ruthless thugs. Because of aphrodisiacs, I indulged in lewd sex… "No way…" It wasn't hatred, regret, or unforgivable feelings… My emotion was "sexual excitement." I became aroused by the sight of my girlfriend being drugged and sexually assaulted by other men. Even after being penetrated, and with the semen flowing backwards, she still pursued him… It was a trashy erection, NTR.
