"Stevie, I'm bored." Stacy sat down on the sofa next to her brother.
Steve looked over. Stacy was naked, as usual lately. She'd stopped wearing clothes around the apartment ever since they'd started fucking regularly a few weeks into the pandemic lockdown. Not that she usually wore a lot anyway.
Steve gazed at his sister's firm young tits and closed his laptop. "Good thing I wasn't on a Zoom call."
"Hey, that would have been fun!" She laughed. "Maybe we should do an OnlyFans. We could make some money while we have sex."
Stacy had lost her job and been kicked out by her roommates, which is why she'd moved in with Steve. The sex had started not long after, on a hot day when they were both too horny to care about anything but getting off. They were fucking all the time now, and Steve wondered what they'd do if the pandemic was ever finished.
But that didn't matter right now. "We'd have to be careful not to let anybody know."
"I could order a camera." Stacy seemed excited. "But in the meantime..."
She reached over to unzip Steve's shorts.
He pulled his shirt off and tossed it across the room. Stacy grinned as she pulled his shorts down, his cock jutting out hard and eager. She ran her fingers over the shaft, licking her lips. "I always wondered what this looked like. When we were, you know, younger."
"Yeah." He'd dreamed about Stacey's tits for a long time too. Now he could enjoy them all the time, squeezing them, licking her nipples, and watching them bounce as she rode him. Sometimes he liked just watching them rise up and down while they watched TV together.
Steve stood up. Stacy kneeled on the floor, smiling at his thick cock, her hands on his legs as she leaned forward. Slowly she took his hard rod between her soft lips, sliding her tongue around as she eased it in. It wasn't the biggest she'd ever had in her mouth--or her pussy--but it was toward the top of the list. She felt Steve shiver with lust as she took it inch by inch.
Steve gasped as Stacy's fingers tickled his balls. They'd fucked this morning already, in the shower, Stacy leaning over while he pumped her from behind, trying not to slip on the wet tile. "Mmm, nice," Stacy had moaned, furiously flicking her clit while Steve rammed into her, both finally cumming with the hot water splashing all over their naked bodies.
Now, with Stacy's mouth around his dick and her fingers teasing his shaft and balls, he had to concentrate on staying on his feet again. He put a hand on her hair to steady himself and rocked back and forth, pushing his cock deeper toward Stacy's throat.
Stacy moaned as Steve's hardness throbbed in her throat. Her pussy was tingling, and she couldn't wait to get his cock down inside her pussy, but for right now she liked the feeling of control she had over her brother. With his dick in her mouth she felt powerful. Giving him pleasure made her feel in charge--which turned her on even more.
"Oh yeah," Steve murmured, a hand on Stacy's neck. His prick was pulsing. He'd been thinking about this all day, even after fucking her in the shower. They couldn't get enough of each other, at least so far. He bit his lip and looked down, enjoying the view from this angle--Stacy's bare shoulder, her hair down her back, the curve of her ass, the way her head bobbed back and forth, her cheeks going in and out as she sucked, her hands on his shaft--
"Ahh!" Steve shouted. His cock erupted, pumping cum into Stacy's mouth and down her throat. Stacy kept sucking, swallowing, running her hands up and down as he came, smiling as his body shook and he groaned until he was finished. Then she drew her head back and wiped a hand over her lips.
"You like that?" She looked up at him.
"Caught me off guard." Usually he didn't cum that fast. "Give me a few minutes and--"
Someone knocked on the door.
"Shit." Steve bent down for his shorts. Stacy laughed and ran from the living room. Still breathing heavy, he grabbed his shirt and headed to the door to look through the peephole. "What the hell?" Then he picked up a mask, slipped it over his face, and unlocked the door.
In the hallway stood a short woman, in her 20s, with short black hair, in blue gym shorts and a tight halter top. She was barefoot. "Hi, I'm Katie, I live across the hall?" She smiled. "Have you seen my cat? I can't find him anywhere."
Steve stepped back. The woman's halter barely held back her tits, and he tried not to stare. "Uh, no, I don't think so. Do you want to come in and look?"
Katie looked past him, then shook her head. "No, that's okay. Sorry to bother you." Her eyes flickered down his body.
Uh-oh. Was cum dripping down his leg? "No bother. That's okay. I hope--"
"Stevie, who's this?" Stacy came up behind him, tying a mask on her face. She was wearing a long T-shirt and apparently nothing else. He could see her nipples pressing against the cotton. So could Katie, probably.
"Uh, Katie. Across the hall. She's looking for her cat. This is--I'm Steve, by the way, and this is my sister Stacy."
Katie blinked. "Your--your sister."
"Yeah. She lost her job and she's been living with me and..." Oh shit. Shit shit shit. Fuck!
But Stacy just laughed. "Yeah, I'm the annoying kid sister. This pandemic is driving me nuts. It's nice to see a new face."
"Yeah, same here." Katie took a step back. "Well, thanks. Sorry to bother you."
"Any time!" Stacy waved as Steve locked the door.
"Shit." Steve shook his head as he pulled off his mask. "She knows."
"Knows what? She's just looking for--" Stacy stopped. "Oh. She knows."
"It's because of all your screaming." He walked back to the sofa. "'Fuck me, Stevie, fuck me harder!'"
"Or it's because you bellow when you cum." Stacy sat down next to him, tossing her mask on the table. "So what?"
"So what? She knows we're brother and sister, and she knows we're fucking--"
"So what?" Stacy said again. "We're grownups. We're consenting. What difference does it make?"
"But..." He looked at the door. Then he looked at his sister. Then he shrugged. "I guess you're right. Hell, mom knows. And Anna." Their aunt, who'd visited them a week ago.
"Yeah. We gotta call Heather and see what Anna told her." Heather was their cousin--Anna's daughter. She'd been on her way to visit when she walked in on them unexpectedly--in the middle of fucking each other.
Then she'd joined in.
"Anyway." Stacy stretched and then pulled off her T-shirt. As suspected, she was naked underneath. Her boobs bounced enticingly. "You owe me something, big brother." She placed a hand in his crotch. His cock was already growing again.
Steve grinned. "Work, work, work." He reached over to Stacy's legs, sliding a finger around her damp pussy as she pulled his shorts down.

Stacy was watching a movie the next morning when she heard a knock at the door. With a sigh she paused the movie, got up, and went to look through the peephole.
Katie. Stacy smiled and tied a mask on. Aside from Anna, they hadn't had company for weeks. "Hi, Katie!"
"H-hi." Katie was in a mask, wearing the same blue shorts and a gray tank top. Stacy didn't see any bra straps, but she could see her boobs wiggling inside.
Stacy was in cutoffs and a bikini top. Katie's eyes ran back and forth across her chest, as if comparing their tits, and then she looked up at her face. "I just wanted to let you know I found my cat. He was hiding in a closet all the time."
Stacy laughed. "That figures. Hey, you want to come in? Have a beer?"
It was 11 in the morning. But she didn't have anything else to do. "Sure."
Katie sat down as Stacy brought beers from the kitchen. She turned off the TV and lifted her bottle. "To finding cats."
Katie giggled, lifting her bottle. She pulled down her mask to gulp the beer. "Where's your--where's Steve?"
"Taking a nap. He was working all night."
Katie's eyes widened. "All night?"
Stacy laughed. "No, it was really work. His company called him with some emergency. He wasn't finished until dawn. Poor guy."
"Oh." Katie kept her mask off. They were at least six or seven feet apart. "You mean, uh--"
"Yes." Stacy crossed her arms. "We're fucking. We were so bored, and so horny, and so--well, he's a good-looking guy, even if he is my brother. You can see that, right?"
"Yeah." Katie gulped her beer. "It's okay. I mean--it's none of my business anyway. I just--I thought I was the only one."
Her sentence hung in the air for a moment. Then Stacy laughed. "You fucked your brother too?"
Katie blushed and took another swallow of beer. "Y-yeah. I just--I could hear you guys sometimes, and I figured you were just boyfriend and girlfriend, and then yesterday when Steve said--I didn't know what to say. And I couldn't stop thinking about it."
Stacy smiled. "Why don't you tell me about it?"
