I closed my eyes again and wondered how long it would take for him to be content. Then I felt warm wetness over one nipple and my eyes flew open.
He’d taken my nipple in his mouth and he was sucking on it. I couldn’t believe it. My own brother was sucking my nipple. It was wrong on so many levels. And yet it did feel pretty good.
“Tristan, what are you doing?” I demanded.
“Sucking on your tit,” he said, his voice muffled by my boob.
“I can see that,” I said. “This is so wrong.”
He didn’t say anything, he just had a big goofy grin on his face as he suckled on my boobs like a toddler. Every so often his eyes would flick up to look at my face and he seemed to be waiting for a reaction. But I gave none.
I leaned back against the headrest and Tristan moved with me, never once letting his lips leave my nipple that he sucked on so hungrily. He settled into my lap, lying on his back, and sucking like a baby boy.
As my eyes tracked down his lean, muscular body, I noticed the tent in his pants. His cock was standing proudly, straining against the fabric, threatening to burst free.
I gasped. I could see the shape of his cock through his pants and God it was big. Tristan was pretty short for a guy and I’d always assumed he was average at best in the dick department. By the looks of things, I was wrong.
The thought made my pussy tingle. And I hated myself for it. I was disgusted with the way my body was reacting to my little brother. I really did. So I tried to ignore it. I tried to ignore everything. I just closed my eyes and tried to imagine I was somewhere else.
Tristan kept sucking on my tit, sucking harder and harder, kissing and licking my nipple. I just lay there, letting him do what he wanted. His hands were running all over my body and it was a strange feeling. Between my legs, a burning desire was growing.
I reached out, not really aware that I was even moving, and my fingertips touched the tip of his cock. He froze for just a second before he resumed sucking.
I ran my fingers along its considerable length and it quivered at my touch. I needed a closer look. I slid my fingers beneath the waistband of his pants and pulled them down his legs. He lifted his butt to help me out and then he was before me in all his erect glory.
His cock was long and thick. It was long enough that it had to be 10 inches and it was as thick as my wrist. It stood proud and erect and I just stared at it in wonder. I’d never seen a cock so big.
I stroked my brother’s cock. I couldn’t help myself. It was so warm and heavy, and I just wanted to play with it. I was shocked at myself for even touching it. It was my brother’s cock. But it was magnificent.
“You like that?” Tristan asked, as I ran my fingers over the smooth skin.
“You have a half-decent cock,” I admitted, blushing in embarrassment.
He took my hand and wrapped my fingers around his cock. They only just closed around his impressive girth. He slid my hand up and down his cock and I did as he wanted. I jerked his cock slowly for a while. He kissed my boob. I felt his tongue flicking my nipple and the sensation sent a shockwave through me.
“This is so wrong, so wrong,” I whispered, as I stroked my brother’s cock.
“Stop saying that,” Tristan said between licks. “I can tell you like it.”
He was right. My pussy was aching with lust and my panties were growing damp beneath my skirt. I couldn’t stop touching his big cock, it was so big and so hard. I knew how good it would feel in my pussy, stretching me, filling me up.
Tristan started to groan and he humped my hand as he sucked on my tit. “I’m going to cum,” he said, his voice muffled by my boob.
I wanted him to cum all over me. I wanted to feel that big cock shoot hot cum all over my skin.
I heard the front door open and my dad’s voice calling out, “Anyone home?”
Tristan gasped and his cock exploded in my hand. Hot cum shot out of his cock and splattered all over my chest and my hand, coating me in thick ropey strands of jizz. It was so hot and there was so much cum that it drenched my skin.
I stared down at it, my pussy tingling with lust and my heart pounding. My own brother had just come all over me.
I looked at Tristan, my heart pounding. “What the fuck?” I said.
“I panicked,” he said sheepishly.
I heard Dad’s feet on the stairs and we both jumped up. I grabbed a nearby t-shirt and wiped Tristan’s cum off my tits before I quickly pulled my top on just in time for Dad to arrive at my open bedroom door.
“There you both are,” he said, smiling at us. He looked at us both and his brow furrowed. “Why are you both so red?”
“Uh… it’s just a bit hot in here,” Tristan lied.
“Crank up the AC then you dumbass,” Dad laughed. “I’m gonna order pizza. Come down when you’re ready,” he said before heading back downstairs.
I waited until he was at the bottom before I spoke to Tristan.
“That’s it then. I did what you wanted. Now delete whatever you have on me and we’re square,” I said.
Tristan shook his head and laughed. “Oh, hell no, big sis. After that? No, you kept it a secret for 6 months so I think for the next 6 months you have to do whatever I want. Or I’ll tell Mom and Dad everything. But don’t worry, after the 6 months is over I’ll delete everything.”
“Tristan,” I said in warning.
“Don’t worry, sis. We’re gonna have so much fun that in 6 months you won’t even want it to be over. You’ll get my instructions soon,” he said before sauntering out of my bedroom. I watched him go and wondered what exactly he had in store for me over the next 6 months.
