DASD-570 An irresistible early ejaculation, a superb technique that can't last five minutes.

One day, my sister-in-law Zennai came to sleep, and she and her wife were the opposite, and watching her breasts and obscenity gave me an instant erection, but then she was discovered by Zennai in a sneaking masturbation, but Zennai said that if she could last five minutes, you would do it, and then use her magic technique, and if she finds out she's finished, she'll be out of bed.
