Special Babysitters

This happened a few years ago, back when I was younger. My younger brother and I lived with our single mother, our father having left us for some slut a long time ago. Anyway, our mother worked two jobs, and hated leaving us alone at night when she had to work from 8 p.m. to 8 a.m., so she got us two “guardians”. Rufus and Loni. They were nice enough, but my brother Tyson and I hated them for the longest time.
Anyway, it was about two months after mom got Rufus and Loni to watch us when it happened for the first time. I had gone to be early, and had gotten up to get something to drink when I heard some strange noises from Tyson’s room. I went to the door and peeked in, and nearly fainted. In all of my ten years of life, I had never thought of what I was watching. My brother was lying on his bed, and Loni had his penis in her mouth. He had his hands holding onto her head, pressing her mouth farther and farther down on his small manhood. Yet she didn’t seem to mind the added pressure. Rufus was sitting beside the bed, just watching, his brown eyes never missing a beat.
Tyson let out a small grunt and I saw him tense up, and I knew that he’d come. You see, I had several older girlfriends who had already filled me in about boys and sex, so I knew what was happening. And I couldn’t believe it. Loni slowly got off of the bed and sat beside the bed and I watched as Rufus climbed up beside Tyson and rolled my brother over onto his stomach. Rufus slowly licked Tyson’s ass and then lunged onto him. His dick finding its way up my brother’s little asshole. As he pumped harder and harder into my brother, Tyson keep moaning and wriggling under Rufus. My brother actually liked having Rufus ass rape him. I just stood there watching, unsure of what to do.
Rufus started to pump harder and faster and my brother started to scream things like, “Harder!”, “Faster!”, “Give it to me now!”, and “Cum inside of me!”. Finally Rufus stopped pumping into my brother and tensed up. As he pulled out, I saw the blood and cum leak out of my brother’s poor little raped asshole. Rufus licked the blood and cum as it oozed out, and Loni climbed up on the bed. Rufus laid down on his back and Loni climbed up onto him and started to ride him. Tyson slowly turned around and watched them fucking. Then he climbed up behind Loni and placed his little penis at her asshole and waited.
