Every now and then, Aiko would meet old family friends that hadn't been around in a while. She never noticed how big Mamoru had gotten, until someone mentioned it. Her father even mentioned that he was bigger than Akamaru had been. She didn't care all that much, since it allowed for him to have such a large cock. And she loved it when they were alone. However, it had been some time since she had had his cock. Now that she was eighteen, her parents thought it was a good idea for her to start looking for a man to marry, and her mother wouldn't leave the pair's sides long enough for them to be alone. Aiko understood her mother's desire for this, but the lack of sexual release was making her a bit tense, and more than once, she snapped at her mother and her friends.
