My girlfriend, who once smiled and accepted my 8cm penis, was completely turned into a lustful cunt by my despicable senior's 20cm cock. (SNOS-399)

I met Kokoro in a university volunteer club. Kokoro was both cute and gentle; honestly, someone like me was completely unworthy of her. I have a gloomy personality and few friends… and my small penis is also a source of my inferiority complex. I'm not very good at sex either… Despite all this, she still told me: “Size doesn’t matter at all,” “Sex felt great today.” She was like a goddess, accepting and comforting even my trivial worries. That was the day. If only I could have stopped Kokoro from going to that senior’s house that day… She wouldn’t have been raped by that senior whose penis was only the size of a dick… And she wouldn’t have been so obsessed with that big penis… She actually took it deep into her throat and swallowed it, being thrust hard into her cervix until her belly bulged out, experiencing one orgasm after another… When we had sex, she wasn’t this slutty. She was always smiling at me… The giant penis NTR that utterly destroyed my inner self.
