His beloved girlfriend, drugged and depraved by thugs, had sex with him until her belly was rotten and she became erect. (SSIS-527)

Are those thugs better than me? Damn it. I ran into a gang of thugs from my school days who bullied me… They took me to my now-defunct alma mater, where my girlfriend, Yura, was gang-raped in front of me while I was restrained. I felt incredibly aroused by being penetrated by their penises, and I got a horny erection because of Yura's unknown appearance. It was a forgotten excitement, completely different from my first time having sex. Then, when Yura started acting strangely and I followed her… I never imagined she was having sex with the thugs after being drugged with aphrodisiacs!? Then, I burst into tears, clutching my genitals.
