At a barbecue party held at my wife's parents' house, I spent a fun evening with my wife and her older sister, Yui Hatano. That night, drunk and out of control, I snuck into Yui's room and forced myself on her in what was nearly rape. Before I realized it, I had already creampie'd her. But since Yui didn't resist at all, I became even more aroused and forced her into a second creampie. The acts grew increasingly intense, and I couldn't even restrain myself in front of my wife—eventually, I continued raping her every single day.
