Sunday morning I woke up and wandered down to Tristan's room. It had become a part of my morning ritual to wake him up with a blowjob and now I did it automatically. I don't know how I got to this point where I was waking up and sucking my little brother's dick with barely any hesitation, but here I was. I didn't even get grossed out by it anymore.
When I reached his bed I found it empty. Tristan was already up. I was off the hook. It was weird that I felt a pang of disappointment. Had he actually conditioned me to like sucking his cock? I mean, it was huge, long, thick, and symmetrical. As cocks went, his was pretty perfect.
I didn't hear a sound from anywhere in the house as I made my way downstairs wearing just my panties and crop top. Maybe Tristan had gone out. I was home alone. Mom and Dad would be home this afternoon so I needed to clean the place up but after that, I could slob out on the couch and watch some trash TV.
"Morning, Sis," Tristan said, as I stepped into the kitchen. He was sitting at the table eating a bowl of cereal while he scrolled through his phone.
"It was so quiet, I thought you'd gone out," I said.
Tristan shook his head and his tousled dark hair bobbed on his head. He was wearing his bathrobe and it had fallen open to reveal the light hairs on his chest. "No, I just woke up before you and decided you'd earned a lay-in," he said with a cheeky wink.
I blushed as I remembered last night with him and Chris. "I stopped by your room but you weren't there," I said quickly. If he thought I'd tried to avoid waking him then he'd punish me and I did not want to be subjected to that humiliation. He'd finally started being a bit nicer to me.
"That's okay, you can do your duties now," he said. He pulled his bathrobe open and spread his legs. All I could see from the far end of the kitchen was the top of his abs, but I could imagine his cock hanging limply under the table. "Crawl on under," he said, nodding toward the table.
I sighed with resignation as I sunk to my knees. Already a part of me was hungry for my brother's dick, but I couldn't let him see that. He had to believe I didn't want this or his behavior would only get worse. I lifted the tablecloth and crawled underneath.
Tristan's limp cock dangled between his legs, resting on the seat of his chair with his big, heavy balls. I licked my lips eagerly and crawled over to him. I reached out and took his limp dick in my hand. It was warm. I squeezed it and it slowly began to inflate in my hand like a balloon being pumped full of air. I massaged it gently, watching with fascination as it grew bigger and bigger until I could no longer close my fingers around it. I would never get over how big it was. I wanted to see that swollen bulge of the head pop out of his smooth shaft. I tentatively raised my head and stuck my tongue out, licking the underside of his dick from stem to stern throbbing head and swirling it around the tip.
He moaned gratefully as I licked hungrily from his balls up to the tip, swirling my tongue all over his budding erection. I opened my mouth wide and engulfed his cock head, sliding my lips down over his erection until the tip of my tongue was tickling the small slit in his engorged member. I felt his hand in my hair, gripping my scalp tightly as he pushed my head forward and my lips slid down his length. I could feel his hips moving slightly back and forth and his heavy balls dragging over the chair as he thrust slowly into my eager mouth.
"Yeah, right there," he moaned softly. "Suck it... Suck your little brother's cock."
I sucked him faster, trying to take more of his tool into my mouth. I wasn't getting a lot of success, but I didn't care.
We both jumped when we heard the front door open.
"Kids, we're home. Are you up?" Mom called as she and Dad entered the house. They weren't supposed to be back until this afternoon.
Tristan's fist gripped my hair and stopped me from crawling out from under the table. "Stay where you are he hissed."
"Tristan, let me out!" I protested. There was still time for me to get out from under the table before we got caught like this.
"Do as your told or I'll blab about the car," he said. He closed his bathrobe above the waist but left it open below. A knot of dread formed within me. There was no way he was going to take a risk like this. No way.
I stayed on my knees, almost trembling in fear, as I heard our parents approach the kitchen.
"Oh, you are here. You didn't answer," Mom said. Her bag thudded as she dropped it on the table above me.
"My mouth was full," Tristan replied. His hard cock was still pointing at me aggressively.
"That doesn't usually stop you. Where's your sister?" I heard Mom walk around the kitchen and start making coffee.
"She's still in bed I think," Tristan lied. "You're back earlier than I thought you would be."
"Yes, turned out checkout was earlier than we thought and I didn't fancy a late checkout charge," said Dad. He dragged a chair out and sat down at the far end of the table.
