You made me do all this!!

"Finally," I said with a sigh, sitting down heavily on the couch about an hour later. You couldn't tell I had hosted a party in this room the night before. "Alright fine, I get why you wouldn't do it by yourself. I guess you aren't THAT lazy of an ass," I finally relented, though only to head off more of his whining.

"Sis, about before..." my brother began as he sat down next to me.

"Yeah, shit, I need it after all that," I agreed, stretching.

"THE FUCK!" he yelled as I swung my legs over his lap and pulled out his dick. He was nice and hard, just like I wanted, and I rubbed the tip against my gash. I was already plenty wet though, so I quickly thrust myself onto his hard dick. The feeling of his big prick piercing my sensitive flesh was exactly what I needed after all the trouble he had put me through, and I hadn't overestimated his size earlier, so he filled me to the brim. I began to thrust up and down on his dick, moaning.

"Fuck yeah, bro! You like that pussy?" I yelled as I rode him. I didn't wait for him to answer, after all I didn't really care, I just needed him to stay excited while I used his dick to get off. I grabbed his hands and pulled them to my tits, which I figured would feel great and keep him going strong as I pounded his dick into my hungry pussy hard and fast. He just groaned, enjoying how the fabric of my dress felt over my breasts as he played with them.

He grunted and and groaned a bit in complaint at how hard I was fucking him, but his pleasure didn't matter. I was gonna fuck him hard, cum all over him, and have him shoot all his cum into my cunt. That would teach him to not listen to me. After all that cleaning, I didn't have that long until mom and dad would get home to make my point, so I fucked even harder and faster using his hard dick like the living dildo it was, cumming once, then again on his prick, as he fucked back up at me, almost as if trying to fight not to, and somehow held out against my practiced pussy. I messaged him inside myself, trying to draw out his worthless cum, after all if he didn't hurry up and fill my pussy, I wouldn't be able to shove my dripping cunt in his face and make him watch his cum drip out of me, and then how would he learn his lesson?

"Are you fighting again?" I heard my mother's voice ask from next to us. I slammed down harder on his dick as I realized I had lost track of time fucking myself to 5 orgasms on my dumb brother's dick. My brother had frozen when he heard mom, his own head also whipping around to look at her, his hands suddenly flying off my boobs as if they were on fire, leaving my hard nipples to stick prominently through my dress, unattended, and me unable to even run his face with them without getting a lecture from mom.

"MOM!! It's not..." he began.

"So I see someone had a party while we were gone," Dad said from behind the couch as he walked past with their luggage.

"What AHHH are you talking about?" I tried to say innocently, voice hitting a bit when John's dick twitched inside me, immediately realizing how fake that sounded.

"Nice try, young lady," mom said testily. "Did you think we wouldn't notice the tons of pizza boxes overflowing the bins? Or do you want to try to tell me you and your brother ate at least 20 pies by yourselves while we were gone for 2 days?"

I glared down at John and slammed down on him particularly hard.

"FUCK SIS I mean there was so muuuch," he whined barley able to manage a whole sentence as I angrily ground my impaled pussy on his dick. He was frantically looking between me and mom sitting there next to us. "I couldn't do much about it."

"I am going to assume this is another of your sorority pledge things, and you took advantage of your brother to help you try to cover it up?" she added archly. "We didn't leave you in charge for this. You are 20, you shouldn't be carrying on like a teenager anymore," she added testily. "I swear, that sorority is a bad influence. Anyway, at least you did clean up... But you had better make up for dragging your brother into this."

"But Mooom..." I couldn't help reply, slamming up and down on his dick hard one more time.
