To find Lily.

While one twin jerks off her brother and accepts his sticky load in her hot mouth, you wonder where the other twin is. She's obviously not in her own room--unless she was hiding in a closet while her siblings got physical--and your parents have commandeered the living room downstairs to watch their own movie. With light footsteps, you move down the hall until you hear some erotic moans, emanating from Abby's room. The door is slightly ajar and you take a peek.

Sitting together on the floor are Abby and Lily, eyes glued to the screen where the movie 'My Daughters Are Teenage Cockhounds' is playing on the screen. Both are sitting with their legs crossed, Abby wearing a pleated skirt while Lily has changed into silk pajama shorts You can tell that they've been watching the movie for a while, evidenced by the four plump, hardened nipples rising from their tits and the damp spots staining their crotches. Having watched the porno earlier today, you know the titular daughters have already spied on their well-hung father in the shower and gotten the hots for his massive dong. Now the plot has moved to the point where the girls are 'accidentally' letting their dad watch them as they fuck other well-hung lads to arouse his hunger for their nubile bodies.

You're pleased with this development. Lily must have been looking for a space and Abby must have offered her room. Two for the price of one, you think.

As one scene ends with one sister and another begins with the other, Abby turns to her older sister. She's looking all hot and bothered. In a low voice, hard to hear from the doorway, she asks, "Why are you watching this, exactly?"

Lily shrugs, her breasts bouncing lightly. "Our brother wanted a second opinion for the review he's writing," she replies, coughing to clear the husk in her voice. "I owed him a favor for helping out with Violet earlier and this was an easy way to repay him. Thank you for letting me use your tv."

"No problem," Abby says, but her eyes have been drawn back to the action. The older daughter has invited two star basketball players home for dinner and, as her father sits on the opposite side of the table, surreptitiously pulls their big, black dicks from their pants and strokes them to full hardness. The father sees the easily identified motions but chooses to ignore them. A couple of minutes later, he excuses himself and hides in the next room, allowing him to spy on the threesome when the real action starts. The girl slips to the floor and soon she has her mouth and throat stuffed with some dark meat, twice over. Her dad can't help but masturbate as he watches.

"I dreamed about him last night," Abby says abruptly. Lily's concentration is broken and she turns her head.

"One of the actors?" she asks, confused.

"No, our brother." Abby wets her lips, her eyes never leaving the screen. Then she adds. "It was a sex dream, one of the hottest one's I've ever had. I had to throw my favorite pair of panties into the wash this morning because of how much I creamed them."

Lily clears her throat and she places her hand on Abby's knee. "Did you fuck him? In the dream, I mean." Her tone is hard to define--curious, disbelieving, jealous?

Your youngest sister shakes her head, looking at Lily. "It's kinda fuzzy, you know. I think he just fingered my pussy and came on my face. Other people were there too, though, watching him take advantage of me. I came and I came, I just couldn't control myself. I've never had a dream like that before, so erotic and sexy. Have you ever fantasized about him like that?"

Lily bites her lower lip, making a decision. Finally, she leans closer, her hand rising slightly on Abby's leg. "Yeah," she admits. "The other four of us kids hung out at the pool yesterday and things...got a little out of hand. I saw his cock a couple of times, even got a good feel of it, and by the time we got done swimming, I was so horny that I just needed to cum. I came back here and played with my clit until I came two times, thinking about what it'd be like to have sex with him...to fuck him."

Abby's breath quickens and her forehead starts to perspire. Her sister's hand has risen even higher, but she makes no move to shake it loose. She looks back at the screen, where the father is still watching his daughter get double-teamed by the hung black boys, one cock penetrating her pink pussy while the other explores the depths of her anus, her eyes rolled back in her head. She speaks again, tentatively tilting her chin toward the movie. "Have you ever thought about our father like that?"

An impish smile creases Lily's mouth. "I've always been a bit of a daddy's girl," she admits.

Interesting. You hadn't planted that thought, but apparently your sister has already leaning in toward her incestuous side.

Your sisters are extremely close now, their sides leaned against each other, Lily's hand venturing toward a sweet, sweet treasure. Abby says, "Any...anybod...anybody else?" Her voice is thick and unsure.

The moment hangs, frozen. The movie plays on behind them, forgotten and unnecessary. Nothing moves. Not a breath stirs. Even your heart seems to have paused.

Then Lily kisses Abby. A full-throated, passionate kiss that is immediately answered, tongues darting back and forth like a whirlwind and breasts mashed together in a delightful mess of soft curves and pointy nips. Lily's hand completes its journey, pressing against Abby's seeping pussy with deliberate and forceful stroke, sliding across the thin cloth and making her hips buck forward. Your youngest sister moans and wraps her hands into the thick red locks framing Lily's beautiful face, pulling her in closer and urging her to continue.

"I need to taste you," Lily says, breathless. Abby whimpers in agreement. The older girl pulls at Abby's skirt and panties, tugging them down as her sister wiggles her hips to help the process. At the same time, Abby reaches for Lily's silk shorts and lowers them as well, leaving both of them completely naked and horny, lusting after each other's wet snatches.

Abby takes the lower position, lying on her back as her sister climbs on top, placing her cunt above Abby's mouth and giving you a glimpse at her tight rosebud. In the next instant, your sisters are locked in a lesbian 69 and you're mentally cheering them on. You can see Abby thrusting her tongue between her sister's folds, lapping up the copious fluids before diving back in for seconds, then thirds, then fourths. Lily shudders as Abby's questing tongue finds her sensitive clitty.

"Fuck yes, right there! Lick there again!" Abby obliges, attacking it relentlessly.

But Lily isn't remaining inactive. Her approach is slower, more methodical. Paying more attention to the inside of Abby's pussy, Lily dives deep into her cunt, probing and delving every corner of her hidden depths. She pushes Abby's thighs apart, allowing her even more room for her pussylicking. Pretty soon, all you can see is her red hair shaking wildly as she munches enthusiastically on her sister's honey hole.

Neither one lasts long, although Lily cums first, with shrieks muffled by her sister's crotch. After her orgasm subsides, she goes back to work and Abby has to bite her knuckle to prevent her screams from permeating to the rest of the house. Lily flops to the floor and your sisters lay there, sexy in the afterglow, their nude bodies making your dick ache.

So far, the night has been an overwhelming success. Your siblings' inhibitions have been crumbling and they've initiated contact with each other without your assistance or suggestions. There's still more work to be done, more passions to inflame, but you can almost taste the hedonistic paradise you hope to enjoy with your family.
