"Are you sure you want to do this?" his sister asked.
He looked at her for a long second, then nodded. "Yeah. I'm sure."
"Okay, then." Stacy reached behind her back to untie her bikini.

The lockdown sucked for a 22-year-old guy.
When the pandemic began, Steve's company sent him to work at home. He could do graphic design just as well remotely, but he missed his co-workers. Especially Dana, with her cute little butt in tight jeans, and Ashley, whose tits always strained at the buttons on her blouse. Zoom meetings just weren't the same.
But work was money. He put up with it, trying not to stare at Gayle, the 52-year-old CEO, during online meetings. She'd started wearing loose T-shirts and he was sure she'd stopped wearing a bra.
Then his sister Stacy, 24, lost her restaurant job. Everything was closing up. Stacy couldn't afford the apartment she shared with two roommates. She called Steve frantically. "They're kicking me out, those bitches! They've got jobs! I can't wait tables by remote control! What am I going to do?"
Steve had a spare bedroom. "You can stay with me, Stace. Until this is over."
"Thanks, Stevie. I owe you one!"
So Stacy moved in. He thought for a few weeks. A month at most.
But weeks turned into months with no end in sight. The virus was still everywhere. Nothing was opening up. They were stuck together in a small two-bedroom apartment with crappy air conditioning as the summer wore on, getting hotter every day.
Which meant Stacy hardly bother to get dressed anymore.
Most days she wore only shorts and a sports bra, or a tank top without a bra. Sometimes just a T-shirt and panties. And that was getting to be a problem.
Stacy was two years older. So by the time he was 18, he couldn't help noticing how sexy she was. At 20, she had long blonde hair, tanned, athletic legs, and boobs that bounced whatever she was wearing. Steve tried to ignore her, but he couldn't. He got his share of girls in college, but he could never quite stop obsessing over Stacy.
He'd get mad when she was late coming home from dates, especially when she walked on, smiling, her hair a mess. She'd wink at him on the way to her room, sometimes humming a song under her breath. It took Steve a while to realize he wasn't mad at her--he was jealous of her boyfriends. They got to fuck her. His sister. His sexy sister.
He took a few pictures of her in a bikini, and jacked off to them constantly. He knew it was weird, but he couldn't help himself. He tried peeping in on her in her bedroom or the shower, but she'd catch him and yell.
One time she snuck a guy in while their parents were at a party. "Don't tell mom and dad," she told him, and led the guy--a football player, big and Black--to her bedroom. He waited a few minutes, then leaned outside her closed door, listening.
"Oh," Stacy groaned. "Yeah. Right there. In there. Oh! Wow. Yeahhh..."
"Right," the guy grunted. "Oh, that feels so good. Let me--oh, it's right in there. Yeah. This is it. This is..."
Steve ran back to his bedroom, pulled the pictures of Stacy up on his computer screen, and jacked off furiously, thinking of them fucking. Picturing Stacy, naked, that big black cock driving in and out of her pussy. The guy pawing her tits, sucking at them. Stacy moaning, squirming, cumming.
Steve came harder than ever that night, more than just once.
It got better after Stacy left for college. She almost never came home for breaks or summer vacation, so Steve managed to forget his obsession. When they ended up working and living in the same city, they saw each other every few months or so, but Steve hardly ever thought of her body the way he used to.
His longtime girlfriend broke up with him two months before the pandemic hit, though, and he'd been too busy with projects at work to really try getting any dates. So when Stacy moved, he hadn't been with a woman for a long time.
Now Stacy was here all the time, and all his weird feelings for her were back.

The afternoon was hot and sweaty--98 degrees and not a breeze anywhere, even with all the windows open. Steve sat in the living room working with his laptop in just his boxers, the ceiling fan swirling overhead. The air conditioner was on the fritz again, and the building manager was useless.
Stacy walked in. "I am so fucking bored!" She sat down on the sofa across from him.
"Me too." Steve looked up. Stacy was in a black bikini top and cutoff shorts. "This fucking sucks. And it's so goddamn hot."
"Yeah." Stacy looked her brother over. He was no model, but he worked out regularly. Not being able to go out to the gym, he made up for it lifting weights at home, and his stomach was flat. His chest was nicely muscular.
Steve saw her looking at him. "What?"
"Aren't you working? Why don't you put on a shirt?"
"Why don't you? I don't have any meetings. I can wear what I want. Just like you."
She laughed. "Yeah, like a bikini, right? You like this. Don't lie--I found those pictures on your computer years ago."
Steve hid a groan. "I was a kid then. I had other girls' pictures too--did you see those?"
"Yeah." Stacy grinned. "What was her name? Allison? The one with the big tits?"
Allison Harney. Not his first girlfriend, not his last. They'd fucked all through his senior year, until she went off to college. Her boobs were pretty awesome. He remembered the first time she took her bra off for him, the way they jumped out, the way her nipples tasted when he put his lips over them for the first time--
Steve jerked his head and pushed memories of Allison from his brain. It hurt to think about sex after so many months without it.
Stacy seemed to read his thoughts. "I'm so fucking horny! This pandemic sucks!"
"Yeah, thousands of people dead, but the big problem is you can't go out and get laid." He picked up a bottle of water for a swallow.
"Shut up, asshole. Don't tell me you're not suffering. Or are you doing Zoom sex with one of your bimbo girlfriends?"
He laughed. "I wish. Thank god for internet porn, is all I can say." The bottle empty, he set it down next to his cell phone.
"Yeah." Stacy stood up and stretched. Steve's eyes drifted to her tits, straining against her bikini top. He looked away quickly when she glanced down at him. "At least I've got Mr. Hummer."
He'd heard Stacy's vibrator buzzing from the hallway more than once. "Time for a quick one?"
Stacy smirked. "Maybe." She turned and walked away.
Steve watched her ass jiggle, then sighed and went back to work.
His cellphone buzzed with a message from his boss. He replied, stared at his laptop screen for a while, then picked up his water bottle. It was empty. He stood up, stretched his arms, and headed for the kitchen.
He froze in the doorway.
Stacy was sitting on a kitchen chair. Her head thrown back, her eyes closed.
Her cutoffs and panties were at her ankles, and her knees were wide. She had two fingers in her pussy, her other hand stroking her clit.
"Mmm," she sighed. Her fingers were a blur as they stabbed her pussy, back and forth, in and out. A trace of moisture dripped from her lips. The other hand rubbed and squeezed the mound of her clit, hard and firm.
Her tits bounced in her bikini top as she rocked on the chair. She bit her lip, moaning quietly as she came closer and closer to orgasm.
Steve stepped back silently, staring at his sister's shaking body. Back in the living room he sat down, stunned, and realized his dick was as hard as a rock. Harder than it had been in days. Weeks, maybe. It was sticking up through his boxers, throbbing like a snake.
He could go to his room. It wouldn't take long. Then he could go back to work--
Fuck it. Steve yanked his shorts down and wrapped a hand around his shaft, sliding it up and down as his balls shook.
He closed his eyes, picturing Stacy's body, her tits in that bikini, her pussy squirting all over her fingers. Oh yeah. He forgot all about her being his sister. All he could think about was the sight of her in that chair, shaking and moaning as she dug her fingers down deep inside her.
"Uhh," Steve moaned. His hand was slippery now with the precum leaking out the tip of his prick. He clenched his teeth, his body shaking on the chair. In his mind he saw Allison Harney, on her knees, sucking his cock, looking up at him with a smile, and then it was Stacy, licking the head of his dick and then trailing her tongue down the bottom of his shaft, cupping his balls as his cock jerked.
He tried to go back to Allison, but he couldn't kick Stacy out of his head. She was grinning, tickling his balls with her tongue as she stroked him, then slurping his dick down her throat, tilting her face up to keep her eyes on his face as she sucked him, mumbling around his hard staff as she eased him down her throat--
He gave his cock one last frantic stroke and came, his cum shooting up from his dick and then pumping all over his leg as he gasped, his chest heaving as he spurted over and over again.
Then he opened his eyes.
Stacy was standing there. Of course. "Gross," she said.
Oh fuck. But he was too far gone to care. He kept pumping his shaft, dumping his cum over his legs and down onto the carpet, not giving a damn if Stacy saw him or stalked away. He'd been too horny too long.
Finally his balls emptied themselves out, and he sat up, reaching for a box of tissues.
"You done?" Stacy smirked.
"For now." He started wiping his cum up.
