STARS-326 Fall in love with your lover's younger sister

My girlfriend and I have lived together in Tokyo for four years. She never considered getting married, and always had to work the night shift and then go back to sleep in the morning, so I haven't had sex with her in three months. The university entrance exam was about to take place. Hikari, my girlfriend's younger sister, went to Tokyo to take the exam, so she stayed at my house for a day. She was really beautiful, and she wasn't wearing a bra, so when I looked at her, my penis automatically stood up. While we were both in the bathroom, there was suddenly an earthquake. She and I were so close together that she discovered my penis pointing straight at her. And from that moment, she began to tempt me, making me ejaculate continuously inside her. I know she likes me, every time I talk about buying a house with my girlfriend she gets sulky. When she left, I realized I wanted to be with her more, but she knew we shouldn't belong together, so she left. A few months later, my girlfriend and I got married, she also got into the university she wanted, she blessed me, the days with me were the most beautiful times of her life...
