The sister decided to spend the night with her brother and gave herself to him.

One evening, the sister came to her brother because she was afraid to stay alone. Once she was in bed with him, she started masturbating, and her brother, watching her, began to jerk off. And as soon as he was about to cum, the girl grabbed his cock and took it in her mouth. The brother came in his sister's mouth without thanking her in any way. The next morning, he wanted to thank his beautiful sister after all, and he suggested that they repeat what had happened the night before, but add real hard sex. So he finally fucked his hot sister and came inside her.
