I want you to mentally sense the words conveyed through Erika's eyes and expressions. Erika Ozaki, my older brother's wife, and I, the protagonist, ended up staying overnight in my brother's room. However, my brother suddenly had to go on a business trip and couldn't return. As a result, I was left completely alone with Erika. While she was quietly bathing, I picked up her underwear, and she noticed. Without a word, she came over and lay down beside me, and we immediately began having sex. The sounds of our intercourse echoed through the room, making me increasingly aroused, my cock staying rock hard the entire time. Being with my brother's wife feels incredibly good—so good that I can't resist. My guilt toward my brother grows stronger, yet my cock ignores all reason and erupts in a creampie.
