Around eleven o'clock...

I was in my bed, I had just slipped in still naked. I am glad I didn't fell asleep too fast that night. After a little while I heard the door of my room creak as it was being opened. My little brother was standing in the doorway, with his slightly shy posture and small figure. I turned on the lights to see to my greatest surprise that he was still naked too and stroking his half limp dick. He blushed furiously as tears filled his eyes before he began to talk. Then he told me: "Can you... please I... I can't... It's no use..." He was looking down at his member. I couldn't believe my eyes. I was convinced I had doomed us by my actions and that I had no other choices now but to keep on abusing of him or never see him again and risk jail, but here he was begging me to help him to play with his cock. It seemed that a whole day of sexual **** and **** had awoken in him the submissive little puppet, and it also seems that I procured him enough pleasure to accept that new role of his. I sat on my bed and gestured him to sit by me, which he did without ever taking his right hand off his dick. That's when I noticed how much he was now into this. At first I couldn't see where his left hand was while he masturbated with his right one, but now I understood as I saw it come out of between his ass cheeks so he could sit down.

Once he was beside me on my bed, I took his hand off his cock and wrapped mine around it. He instantly got hard and quickly began spurting pre-cum. I stroked him a little before stopping to nibble on his perk nipples which seemed very sensitives. Then I grabbed him by the hair and yanked his head back a little and asked him a decisive question.
"Alright you little twerp, you seem to have turned into a real little sex addict haven't you?" He nodded.
"I have a deal for then. In exchange for making you cum and satisfying your urge for sex you will have to become my ****, OK? You'll be treated like my little pet, my bitch. You'll have to obey every single order I give you. How does that sound?"
He took a moment to stare at our dicks before he said "Yes, OK. I'll do it." and began stroking his dick again. I told him to stop it, and he did, reluctantly. Then I ordered him to ride my cock, and he took a hold of my erected rod and aligned it with his painful ass. Since he came in my room, I've been dripping pre-cum non-stop, so my dick slid in his back door with ease. he sat on my hips with my cock buried inside him and a lustful look in his eyes. It was still hurting him and it showed, but now he also loved it. He was facing me and slowly began hopping up and down, impaled on my hard shaft. I held him by the thigh and ran my hands up to his ass. The whole time, I kept shifting my hands between his ass cheeks, his prick and his hard nipples. After a while he came all over my chest with a tremendous orgasm that **** him to squeeze his rectum with random, uncontrollable spasms that made me empty a generous load up his ass. Then I laid down, holding him by the neck, keeping my cock deep inside him, and made him eat his own cum off my chest. When I pulled out of his ass I made sure to get all my cum that was slurping out of him in my hands, and then made him eat it too.

An hour later I dressed up, and strapped two leather belts together, with one around his pale neck. It was all he had on him and I took him outside. We stayed in the shadows until we reached the small park nearby, then I walked him there for while. After ten minutes I sat on a bench and told him to suck me. The whole time we were in the park he had a raging hard-on. When I got close to cumming, I stopped him and pulled out of his heavenly mouth to cover his face with my hot semen, then we walked back home with his face covered in cum.

That night we didn't sleep much and the next day, he could barely sit down.
