Half-sister makes him ejaculate over your pants

I Was sleeping, I was in a trance, a deep sleep. I felt completely liberated, light as a feather. But when I woke up, I understood the reason why. My half sister, I had put her vibrator on his penis and had me masturbate. I ejaculated while I was sleeping. Made me angry to the point that I went up to his room. But he was laughing. For this I have given you a lesson. And the same day I asked her to fuck me. I insisted to such a point that he agreed to make me a saw. While I masturbated, I started to stroke her wet pussy. This has made her wet vagina. And then she wanted my penis.
