At my wife's parents' house, I enjoyed a yakiniku party with my wife's older sister (Yui Hatano), and I got drunk and attacked Yui in her sleep. When I noticed it, it was after vaginal cum shot, but I couldn't suppress her excitement that Yui didn't resist, so I had another vaginal cum shot SEX. The act escalated steadily and continued to commit every day in front of her wife.
