He spied my sister with her friend on sleepover night.

The girls did not let him sleep, he had tried to be kind and not be bothered by their actions, it was the first sleepover of his sister and was happy to see her with another girl, this despite the fact that she was already older than usual in this type of party, but for that reason he had tried to be reasonable, until his patience was exhausted, it was almost four in the morning and they were still laughing and shouting, he prepared to enter the room and give them a good scolding but he found a perverse image that he did not expect at all, the two naked girls touching each other lewdly.
