In addition to incest there is also MM sex. If that is a problem save some time and look for something else.

"What now?" Jill asks, ignoring the flabbergasted look on her father's face.
"Baby, I wasn't joking." Jim tells her, speaking around an enormous yawn. "I've never laid so much pipe is so short a time. I never, not ever, would have imagine saying such a thing, but I'm fucked out. I just want to chill, girl."
"Same here," Ben adds as he turns toward the pool stairs. "I'm going to pull a lounge chair into the shade and take a nap." He looks around. "Anyone know what time it is?"
"It was quarter till four when Mark and I left the house," Muriel answers. "It must be quarter past, or half past, by now." She hoists herself out of the pool. "Ben, you mind if I share some of that shade."
"Nope, not as long as you don't snore any louder than Meg."
"Ben Casey, I do not snore!"
"Yeah, you do," all three of her children intone simultaneously. They look at each other and begin to laugh.
"Assholes. The whole lot of you." She follows her husband out of the pool, feigning hurt feelings while suppressing a smile.
She pulls a chair over and stretches out on her back between her husband and Muriel, their long-time lover. Jill can't help noticing how nice her mother's pussy looks, all waxed and smooth and bejeweled with drops of water. She's as tired as the rest but her fatigue doesn't keep her from feeling a tightening deep in her belly.
"Come on, you guys," she tells the others. "They've hogged all the chairs. Let's go inside and take a nap in their bed."
"Why our bed?" Her mother demands.
"It's the only king size. Duh."
Bill and Jim follow her. Mark hesitates. There is a fourth lounge chair he could pull over by Muriel. She sees his hesitation and smiles. "Good on, Mark. Us old folks need our beauty sleep."
"No, you don't. If you were any more beautiful it would be a crime," Mark assures her as he bends to kiss her softly on the lips.
"Christ, son. Don't overdo it. Jesus," his dad snorts as he shifts his butt, trying to get comfortable. "At least pretend you aren't totally pussy whipped already."
"Like you'd know," Meg snorts as she rolls over onto her stomach. "Go on, sweetheart. I don't want to embarrass you when I tell Muriel all your baby stories."
Mark's face settles into a look of cinematic horror. Seeing it, his mom takes pity. "Oh please, you know I'm only kidding." Mark turns. The others are waiting, grinning at his discomfort. "Besides, honey, I've told her all of them before."
Mark shakes his head but doesn't respond.
"Good one, mom." Jill chuckles and bounds up the stairs.
The three men, two of them her brothers, watch her ass move as she climbs the stairs to the deck. All of them, dog tired though they may be, are sporting soft wood by the time they reach the upper deck. The inside of the house feels cool after the heat of the sun.
"Should we change the sheets?" Jill giggles as they enter their parent's bedroom. "It reeks of sex and cum in here."
"Later, I'm too tired," Bill replies and climbs into the bed and crawls to the far side. It's the others' turn to watch his ass. Even Mark and Jim watch.
Jill motions to Jim with one hand. "You next big guy."
"Why does Mark get to lay by you?" Bill whines. "That's not fair."
"See, Jill, this is what we've been trying to warn you about," Jim tells her in a very serious voice. "Look at jealousy already rearing up it's ugly green scaly head."
"Deal, brother Bill, deal," Jill says as she blows him a kiss off the tips of her fingers. "Go on, Jim. Hop in. Seriously, I'm about to fall asleep on my feet."
Jim complies, lying on his side, his back pressed against Bill's front. Jill follows suit, her ass presses against Jim's cock. Mark hesitates. She smiles and holds out a hand. He takes it and starts to lie down.
"Uh-uh, big brother, facing me. Okay?" she says, stopping him.
Mark doesn't speak. He kneels on the edge of the bed and stretches out facing his sister.
"Did you guys notice how gorgeous mom's pussy is, now that she's waxed and it's all slick and smooth?" Jill asks as she wiggles her upper body closer to Mark and grinds her ass against Jim. He may be tired but his cock responds to the soft warm caress of his lover's ass.
"As a matter of fact I did," Jim assures her. "Your daddy was blocking my view but nice as your momma's pussy looks, it felt a whole lot better wrapped around my dick."
She shoves her ass into Jim's crotch, causing him to flinch. "Better than mine feels wrapped around your cock, lover?"
"Jill?" Mark's questions brings her eyes back to his face.
"Yeah?"
Mark notices his brother, Bill has raised up on one elbow to peer over Jim's shoulder.
"I know you're kidding, at least I think you are, but that is exactly what we've been talking about. How can Jim answer that question? If he says yes, will you be pissed? Jealous? My guess is Jim will say 'no' and he'll probably mean it but what if he's lying? Have you considered how you'd feel if the answer was 'yes', that he did enjoy fucking mom more than you? Could you handle that?"
"Sure, as long as I knew he loves me more than mom." Her answer is quick, her voice easy, almost chipper. Mark holds her eye. She shrugs. "Okay, fine. It would bother me. But only a little. My ego isn't so frail that I'll fall to pieces over the idea Jim has had lovers better at fucking than I am." She pauses, "But the physical part of sex, great as it is, isn't the only thing that goes into making love. What if for some reason I couldn't have sex anymore? I don't know why, but just say I couldn't, that doesn't mean Jim wouldn't still love me. At least I hope it wouldn't."
"White girl, don't be dense. You know it wouldn't."
Mark looks past his sister at Jim, a man he's only beginning to know but already likes, likes a lot. "You sure, Jim? That would be a lot to give up."
"I'm sure." The answer is given in a steady voice and with a steadier eye.
"That's sweet, baby," Jill purrs. "If my pussy is every incapacitated, I'll let you find relief elsewhere."
"Jill, Jesus," Bill groans and she twists her head to look at him. "I love you. You know that. You're my little sister. I love the fact that you're so sure life will always be beautiful, but it isn't. You can say shit like that so blithely, as if none of it matters. It matters. It all matters, a lot. Something that important, that integral to how two people love each other, can't be treated with a casual, off the cuff remark like that. I'm not superstitious but Christ sis, haven't you ever heard of hubris?"
"Yes," Jill replies, reaching over Jim to pull Bill's hand to her lips. She kisses the palm. "Yes, I know what hubris is. I'm not treating the idea of 'love' with contempt or with complacency. I am in awe of how I feel about Jim, about you, Mark, Muriel, mom, dad, everyone close to me. I don't take it lightly. I'm so in awe of it, I believe love can survive anything."
"I hope you're right," Mark whispers, speaking as much to himself as to the others.
Jim's body shakes the bed as he shudders and yawns.
"I'm in awe of love like all y'all but I thought we were going to take a nap?"
"Thanks, baby," Jill says as she snuggles back against him. She kisses Bill's fingertips and releases his hand. She inclines her head, resting her forehead against Mark's. "Night night, boys."
The bed shifts as Bill lies back down. His arm falls over Jim's waist and his fingers gently wrap around the man's half-hard cock. Jill wiggles her ass, saying with her body – "hi there, welcome". If Jim cares one way or the other, it's lost in a low rumbling snore. Soon enough, she feels Bill's fingers relax. He doesn't snore but his breathing is low and soft.
"That leaves just us big brother," she whispers to Mark. She rubs her fingers through his hair, their foreheads still kiss.
"Uh-huh," he grunts. "You should sleep, little sis."
"So should you big brother." Her fingers pluck at his hair. "Why can't you just call me 'sis' instead of 'little sis'?"
"But you are my little sis, sis" he replies.
"Thank you, Mark." She tries to let herself fall over the edge of sleep but can't quite manage to. "I always thought you didn't like me very much."
