Sorry this took so long. This may be the end of this story, depending on the response.
Oh, yeah, everyone's over 18. There's no lesbian action, but there is a mother and daughter masturbating together, FYI.
Thanks for reading.

Steve heard his sister's urgent moans as soon as he opened the door. Stacy was gasping, groaning, grunting, and grinding inside her bedroom, loud enough that he closed and locked the door fast before anyone out in the hall could hear her.
He set down his groceries and pulled off his mask. The lockdown had eased up, and it was safe to go out for supplies, but most people were still masked on the streets and in the stores, and no one lingered. Things were getting better, but the world was nowhere near back to normal yet.
Steve's cock stiffened as he listened to Stacy, and he imagined her naked body writhing in pleasure, her fingers up her pussy, stroking her clit, maybe using one of her dildos or other toys. He grinned and left the groceries on the living room floor as he headed toward her room.
Then he heard a second voice. A man. "Oh yeah, baby... oh yeah..."
Startled, he stopped for a moment, then crept forward silently. Who the hell could it be? The door to Stacy's room was half open, and he leaned over, peering inside, holding his breath to keep from making a sound.
This was just like spying on Stacy and her boyfriends when they were in high school. He remembered a skinny guy with a long thin cock that Stacy sucked and sucked until it spurted all over her face and tits. She'd gotten mad when he couldn't get it up again.
Now Stacy was on her hands and knees on her bed, her boobs swinging back and forth, her blond hair wild around her neck, as a large guy with a tattoo on his shoulder was pounding his cock into her from behind. He was gritting his teeth, squeezing her ass with big hands, his balls flapping against her butt, and Stacy was pushing her body back at him stroke for stroke, driving his hard prick deeper and deeper inside her pussy as her body shook and swayed in a hard, fast rhythm.
Steve stared. Who the fuck was this guy? He opened his mouth, then shut it again. Whoever it was, his sister was obviously enjoying his cock. The first cock she'd gotten since the lockdown started. Aside from Steve's.
Steve and Stacy had started fucking one hot and horny day, and in the months since they'd done it as much as they could. At first it was just desperate horniness, but after a while they got comfortable with each other, enjoying each other's bodies as often as they could, fucking and cumming every day and every night without caring what the rest of the world might think.
Steve's cock got hard again. Harder. He was about to back away when Stacy looked up and saw him. Too out of breath to speak, she winked at him with a wide smile, then lowered her head to concentrate on the cock thrusting in and out of her body.
The guy saw him too. He slowed down for a moment, but Stacy reached back to slap his leg, and he leaned down to get back up to speed. He nodded, and Steve nodded back. Then, with a soft sight, Steve turned and went back to put the groceries away.

His name was Grady, and he had one of the biggest cocks Stacy had ever taken up her pussy. She bit her lip, breathing hard, enjoying the sensation of a fresh cock--her first new one in months--ramming into her. She was going to cum soon, and she was going to enjoy it.
Grady gripped Stacy's hips, his cock throbbing as her pussy squeezed it tighter and tighter with each thrust. Sweat rolled down his shoulders, even with the ceiling fan on overhead. He looked down at Stacy's naked body, her bare shoulders, and grinned.
He slapped Stacy's ass. Not hard, but she yelped, then laughed. He slapped her again, then reached forward to grab her hair, pulling her head back.
"Not so hard," she murmured, glancing back at him. "Just keep it up back there. Just--keep it--up--oh yeah! Yeah! Yesss..."
"Uh-huh," Grady grunted. "Mmm..."
He wondered about the guy outside the door, but he couldn't think about that right now. All he really wanted to do was plow this chick's tight pussy, keep his dick inside her until he came--which was soon now. He could feel it building up in his balls.
Stacy bit her lip. She was ready to cum, her pussy churning impatiently. Grady had a nice cock, and he'd gotten hard fast after her blowjob, but he was too quick, too focused on his own dick. Not like--like--okay, her brother. She closed her eyes and let herself think of Steve. He always took his time. Always made sure she was reaching her peak. He knew where her clit was and what to do with it. He didn't just shove his cock inside and let it do all the work.
But this was the first new cock she'd gotten since before the lockdown. Damn it, she was going to enjoy this. Grady had a big cock that filled her up, and while he didn't have much finesse, he had a lot of enthusiasm. She lowered her head and concentrated on the warm feeling growing inside her pussy. Just a little more. Just a few more minutes. There, that's it, that's good--"Oh! Yes! Yes, yes, yes--"
"Yeah!" Grady shouted as he came, the cum shooting from his cock into Stacy's quivering slit. He dug his fingers into her ass, clawing her skin as his balls pumped and pumped. He gritted his teeth, letting it flow, his stiff cock embedded in Stacy's pussy as it sucked in every drop of his semen.
Stacy dropped forward on the sheets, gasping. She'd needed that. She felt Grady pumping a few more spurts until he finished and slipped his cock free of her pussy, rolling over to lie on the bed next to her.
"Nice," he said. He reached over her body to stroke her nipple.
"Yeah," Stacy sighed.
"Who was that guy?" Grady asked, squeezing Stacy's tit.
"My brother." She answered without thinking. But really she didn't care. Grady wouldn't guess what was going on. And what if he did? It was her business, and Stevie's. Not his.
Grady laughed. "Brother, huh? He going to be okay?"
"He'll be fine." She pushed his hand away. "You should go."
"Yeah." He sat up, looking for his boxers. "See you tomorrow?"
Stacy nodded, still coming down from her orgasm. "Yup."
Grady left. Stacy lay on the bed, smiling, fingering her clit as she thought about his cock pounding in and out of her. It had been nice. He seemed like an okay guy. Maybe if she taught him to slow down a bit...
Slowly she slipped a finger inside her pussy. Mmm. That felt nice. Sometimes a girl needs to just take care of herself, right? She lay on her back, spreading her legs, and slid another finger inside. Her pussy tingled, both from the orgasm a few minutes ago and the prospect of another one coming up.
Then a shower. Then... Steve.

After putting the groceries away Steve went to his room. His dick was still throbbing from watching Stacy, naked and fucking, with whoever that guy was. He pulled off his shorts, sat down on his bed, and opened his laptop to look for porn, rubbing his prick lazily as he thought about his sister's bouncing tits.
Then his laptop beeped unexpectedly with an incoming call. Shit, he thought, his erection starting to face. Then he saw who it was from.
Anna. Their aunt.
Grinning, he moved the laptop so his cock wasn't in view and accepted the call. "Hey, auntie!"
"Hi, Stevie." Anna was in her 40s, with long red hair. She wore a T-shirt, tight, her nipples pressing against the fabric. She smiled. "What you up to?"
