RBD-432 - Stealing My Son's Girlfriend: Locked Up and Taken by His Father

I was expecting a story about confinement and training, but it's more accurate to call this a rape-themed work. If you like stories where a girl slowly falls into depravity through a father's persistent training, you'll find this lacking. The heroine, Yui Uehara, is cute, but it's a shame that her cuteness doesn't really come across in scenes where her hair is being messed up and she's being raped.

Blowjob → rape on the sofa → rape on the bed. It was a very soft production.
