After titfuck, Ryuki let Yui rest but told her to get naked. He sat on the sofa and thought about what he should do next.
There were many things he could do, but he didn't want Yui's first thing that entered her pussy to be a vibrator or dildo. He wanted his dick to be first, but he didn't want to lose his virginity.
The reason? Well, he prefers to lose his virginity to his sister, Saki, or his mother, Fumiko.
With his sister, he was playing a hypnosis game, and his sister had control, not him when to have sex, so it seemed difficult to lose his virginity anytime soon.
As for his mother, then it would take a month time before he might reach a state where he could lose his virginity.
After many thoughts went through his head, he decided to wait for a month. If, in the next month, he didn't lose his virginity to his mother, then he would fuck Yui and lose his virginity.
