My sister has ways of getting me to do her homework

Everyone is at least 18 years old.

My sister, Amy, could easily do her own homework, but she gets a thrill out of getting me to do it for her. I've lost count of how many times she's used her puppy dog eyes to get me to do something for her, only to find out that she'd already done it. For her, it's all about being able to control me.

My sister wanted to spend all night at a party, but she had chemistry homework due the next morning. Of course, I heard her knock on my door as I was studying. We were both a few years into college.

I said, "I'm not doing your homework. We both know you could easily do it yourself in ten minutes."

Amy opened the door. "Of course, but it's not about the homework, it's about seeing if I can truly own you."

I was about to tell her to fuck off and shut the door, but the way she looked stunned me. I'll be honest. I've always thought my sister was hot, so much so, it frustrated me to have a sister that was a goddamn knockout with big round tits. Without a blood relation, I would've tried to hook up with her, or at least jacked off to her.

The way she looked for this party though, in tiny yoga shorts and a tight T-shirt with endless cleavage, it was especially unfair. Her tits were so perky, I couldn't tell if she was wearing a bra.

In a pleading tone, Amy said, "Please bro, just this once."

"Nope, I'm gonna study and go to sleep. No way I'm doing your homework."

"But I really wanna go to this party."

Amy smiled like she had an ace up her sleave. She began slowly pulling up her T-shirt. I could see her flat stomach, and the thought of her showing more gave me the most ecstatic anticipation. I was already starting to get hard.

I remembered her joking a while back that she could get a man to do anything just by showing him her tits, but I was shocked that she would use her superpower on me.

She slowly revealed her Lucious underboobs. I didn't care that my eyes were completely fixed on them. I just wanted more.

Just before she got to her nipples, she jerked her shirt down. I instinctively whimpered, "No."

I'm sure she could tell how crushed I felt by the look on my face. She even fucken giggled at me. She then lifted her shirt right up, revealing her big juicy milkers. I gasped as my cock jumped. I helplessly marveled at their beauty. It's like those breasts were perfectly designed to drive men crazy.

Amy pulled her shirt off, then placed her hands on the back of her head, making them defy gravity even more. She wiggled her tits around as she pleaded, "Pretty please do my homework." Her bottom lip puckered. "I just know you will help me, my sweet brother."

My eyes devoured every shake and little ripple of her tits. My cock felt so hard that it could explode at any moment.

I couldn't let my sister know I was unbearably attracted too her. I made myself smile and chuckle like this was just a goofy joke. "Okay, since you seem desperate, I'll do your homework this one time."

She jumped up and down, shouting, "Thank you!" over and over. Her tits bounced in all their glory.

"You're the best, bro! It's in my backpack in my room." When she turned around to leave, she was even kind enough to bend over wiggle her shapely butt at me.

I tried doing her chemistry homework. I couldn't focus at all, so I had to jack off to thoughts of my sister for the first time.

Over the next week, my sister acted no different, other than she would walk around the house in similarly enticing clothes. Plus, she thanked me for opening a jar by pulling my head into her breasts covered by nothing but a thin white T-shirt. It took effort to not lick them.

I was hard basically the entire week. If her plan was to prime me up, it worked.

Friday night came along and with it, another party. Amy strolled into my room in a pink bra and matching panties, full of confidence.

Sitting in my computer chair, my whole body went tense with anticipation. I forced out a chuckle and said, "What are you doing?"

She strutted over to me as she said in a sexy voice, "I just need your help again." Her tits jiggled as she walked to me. My cock hardened shockingly fast.

Amy pushed my shoulders to make me lean back in my chair. With the lightest flick of her hand, she put cock against my stomach. That one tiny touch sent shockwaves through me. My brain couldn't comprehend that my sister just touched me there. My cock was now pulsating in my boxer briefs.

Amy straddled me letting me feel her bare legs on mine. She pressed her pussy against my cock with nothing but thin fabric separating us. Her legs wrapped around my waist to press even harder. The pleasure and excitement fucked with my breathing.

She pulled my head toward her. My face splashed into her breasts, firm and soft and plentiful, like sinking into mounds of pure ecstasy. They had both the warmth and sweet smell of pie.

Amy guided both my hands to her butt in cheeky panties. My fingers and palm pressed into those plump round cheeks, pushing her pussy even harder on my cock. All her feminine parts were giving me sensory overload in the best way.

She started grinding on my cock, and I couldn't help but moan. Her rhythm got faster and faster, and with stunning speed, I was on the verge of cumming. My face turned left and right against her breasts, licking them with no shame. That pushed me over the edge.

Barely able to speak, I sad, "Yes, I'll do your homework. I'll do anything." I couldn't have said that at the worst time.

Before my cock started spewing, Amy instantly pushed me off her breasts. She looked down at me with the most devilish smile as she climbed off me. The second she turned around to leave, my cock began spraying like crazy through my underwear. My body convulsed with every spurt. I could do nothing but scowl at her perfect jiggling cheeks as she walked away.

She giggled and said, "Thanks bro," leaving me to the rest of my completely ruined orgasm.

While she partied, I angrily did her chemistry homework. I'd never felt so owned and pathetic. I was determined to not fall for her schtick again.

I tried to avoid her all week, but she had new tactics. She'd sneak up on me and wrap her hand around my cock in boxer-briefs. She'd say a casual, "Good mornin'," or "hey bro," and then pump my cock until it was hard.

On Thursday, she found me laying on the couch, scrolling on my phone. While wearing a mini-skirt and a thong, she sat her donk right on my face, wiggling into me for a few seconds. Then she got up laughing and said, "Oops, sorry."

I waited for her in my room on Friday night, determined to reject her. Amy strolled in wearing nothing but a black thong. She stood in front of me with her hands on her hips.

My eyes aimed down to my cock, which was betraying me again. I said, "I'm not falling for that again. There's no way I'm gonna doing your homework."

Amy got on her knees. She puckered her bottom lip and begged, "Please." She kissed my hardening cock through my boxer briefs.

I breathed out, "Fuck."

She kissed it again and again as I groaned. She slid my pulsating cock through my fly. She began flicking it with the tip of her tongue. It felt like she was whipping me into submission

I whimpered, "Stop."

She pressed her adorable face onto my cock and I could feel her lips moving as she said, "But you have such a big dick. Do you really want me to stop?"

I whimpered, "No- but- but I'm not doing your-"

She smothered her tits around my cock.

"Oooff!" My upper body jerked forward.

"You really do have a big cock." She moved her tits up and down as every part of my cock was covered by them. Her skin was soft, like velvet, and the way she looked at me with a mix of lust and playfulness was something I never thought I'd see. She knew exactly how to use her gifts, her movements effortless. Every squeeze and stroke was a masterpiece of sensuality, her breasts enveloping me in a gyrating hug that made my entire body quiver with pleasure.

She pressed her mouth down, finding the head of my cock between her tits. Her mouth took the head. She sucked it. Her tongue swirled around it. That combined with the sensation of her bouncing breasts was almost too intense.

My hands grabbed the back of her head. My breathing grew more ragged. My hips began bucking, thrusting my cock harder between her tits and deeper into her mouth. I went deeper and harder and faster, and went right over the edge.

Without thinking, I moaned, "I'll do your homework! I'll do anything for you! I love you!"

I realized how stupid I was for saying that before finishing my orgasm again. Then my sister, my merciful loving sister, simply smiled up at me with her eyes and kept going. She obviously couldn't speak in this situation, but she tried to say, "Love you too, bro."

With a guttural moan, I erupted. The first spurt of cum shot out, the force of it surprising me. She took it eagerly. Another euphoria-soaked spurt followed, and another, each one accompanied by a deep, primal sound that I didn't know I was capable of. The cum kept shooting while her mouth and tits never left my cock.

When it was over, I lay back in my chair like I was about to enter a coma. My eyes closed.

I felt my sister use my thighs to help herself stand up. "By the way, bro, I already did my homework. I just like messing with you. She laughed, patted my cock, and said, "See ya, bro."
