GVG-144 - Broken Girl: Training My Girlfriend Into a Sex Slave

*It was a far-fetched story about ``teaching her how to make her an obedient pet,'' but I couldn't understand it at all. Even if a professional training man shows up, he doesn't do anything special, just toy with toys and have sex with other friends. Moreover, the presence of a boyfriend who gets excited by secretly filming his girlfriend while he is being raped is just because he wants to be cuckolded? That's what it felt like. In that case, if you're completely in love with your boyfriend, it's easier to understand if you don't want to break up with him, and then he escalates his demands and gradually changes to accept perverted play.
