Man, boyfriend is kinda of a dick. If you're going to be sharing her with a bajillion other guys, you should at least accept the consequences. Ah well, thanks for the upload.

I don't get this dude. Crafted the best slutty girlfriend who only wanted his dick. But then he made her start fucking other people and got mad about it...

I feel more like he got bored of her once she was totally broken, and probably moved on to a new girl to start the process over again. Thats how I read it anywho.

Hah hah. That old lady in the beach scene. "She's already someone's slave at such a young age." I wonder if she's someone's slave herself or a master. Either way, she seems to approve.

Man I wish this artist would produce more content like this. Some of their other stuff is good, but there's just something I love about this like gradual decline into depravity in this particular doujin that just really does it for me. One of my faves.

Probably just a coincidence but bottom-right panel on p.15 sounds like it comes from a Danganronpa 2 hentai if you see what I mean
