Finally our parents were gone for the weekend.
It was just me and my brother, Mason, all alone. We both knew what was going to happen, I’d been bugging him about it for weeks- ever since mom told us they were leaving for my grandparent’s for the weekend.
I waited for him in my room, dressed like this, but not quite as pregnant.
He came in, naked, hard. He step toward me, giving me a big hug, his hands reaching around to squeeze my ass while his shaft poked my belly. He smiled down at me, obviously just about as excited as I was.
My hand wrapped around his twitching cock, rubbing it up and down the way I knew he liked, then kissed him on the cheek. I gave him a smile, then turned to the bed, crawling onto it on all fours, rolling my hips for him.
“Come on Mason, We’ve been waiting so long~” I murmured to him. He knelt on the bed, rubbing my ass as he slipped my underwear down, rubbing me a little.
“Mmh- I finally get to fuck my little sister,” he groaned behind me as he lined himself up. “Big brother’s going to make you feel great!”
It was so strange, when he talked like that I thought it was embarrassing, but so hot at the same time. I moaned a little as he leaned over me, starting to push in.
He was so slow, taking me inch by inch. I just focused on how good it felt, and how wrong this was. But, I wanted it, I wanted it so badly I was soaking his cock. Soon he started his slow thrust, one hand holding my ass as he took me.
Finally, after so long I could feel Mason’s cock, using me the way I’d wanted him to.
“More~” I moaned to him, turning back to see him grin. It was something I hadn’t seen before, how much he wanted me!
His hands gripped my hips like vices, holding me in place as he leaned in, driving himself into me so much harder. My moans grew louder as I rocked back into him until our hips met, filling the room with soft smacks.
“Good girl,” he cooed, leaning over me, his cum filled balls slapping between my legs. God, when he called me that it always put butterflies in my stomach, as if he owned me… I’d never realized.
Each moan was followed by a desperate panting breath… “Harder!”
It just slipped out! But he didn’t care why I said it, he was going to give it to me! Pulling almost all the way out, he slammed right back in, railing me so hard! He shoved my face against my pillow, as I squealed ecstatically!
“Little sis’ likes it, huh?” He asked. “Well?”
I nodded, too embarrassed to look back. “Yess- it feels so good!” I cried into my fluffy pillow!
He groan his sexy, melting groan as he pounded my overly tight passage, deeper with each thrust.
“God, sis’ I’m gonna cum-” he called, telling me more than warning me. Just the thought of it sent shivers down my spine, filling my head. “Cum in me- do it! Please!” I groaned into my pillow.
“My little sister wants me to put a baby in her belly?” He asked, almost too arrogantly, but I still loved it.
“Yess!”
I could almost hear him smile as he plunged down into my tight hole, cumming like a machine, pouring it into my belly~ I came so hard, it was the most intense orgasm I’d ever experienced! Clutching at his shaft, I tried to stroke him with my insides for more- more hot, brother-cum for my womb!
As we both calmed down, he stayed deep inside, rolling onto his side and taking me with him.
Now that Ive gotten bigger, how do I look with my brothers baby in me?
