Lost bet Step Brother Blowjob

My step brother and I had a bet over something and I lost. The prizes were, he would do the dishes and tidy my room etc but if he won he could do anything with me. This was for a week. I honestly thought I would win.

On the first day of his winning

My mother left to go shopping for food. And within minutes he text me " i need your mouth". I went to his room to find him naked sitting on his chair watching porn with a huge hard on. He had a pillow ready for me, for my knees, on the side of his chair. I went over without saying anything and went on my knees. He didn't even say anything to me. He grabbed hold of my head and pulled me down to his cock. As soon as my mouth covered his dick he let out a ahhhh. He continued by pumping my head up and down on his cock like it was his hand. I could hear now and again clicking on the computer. he let go of my head and allowed me to lick his tip. moving my tongue round and around. His eyes didnt leave the computer. He grabbed my head again and bobbed me up and down in a slow pace. He let go of my head expecting me to continue the pace so he could type. Ii did so for another few minutes. He was letting out sighs of relief all the time. His cock began to get harder and he was letting out plenty of pre cum now. He grabbed me head and controlled my mouth again like his hand, pushing me up and down quickly. "Swallow as much as you can" was the only words he said to me. He pushed harder and faster and shot his load deep into my mouth. there was too much of it and he didnt stop so the cum dribbled down his cock. i dont think he cared. It just kept shooting to the back of my throat. Warm, salty cum. He let go of my head and allowed me to finally swallow some. I continued sucking his cock with the cum on it. He tapped me on the head and said "thats enough" . I got up and wiped my lips and went to my room. we continued as normal as though nothing happened.

I knew this was just the start.
