You.

Your mom's head weaves back and forth, staring alternately at her topless son and daughter, her lust-addled mind trying to keep up with the dream but failing miserably. Her fingers are still buried in her snatch, not moving as you wait for her answer. The urge to keep pleasuring herself is very strong and she wants nothing more than to go back to making herself cum, and your question is stopping her. So she picks an answer at random.

"You do," she says, looking at you and lifting her chin to point. "You win the game."

You raise your arms in triumph and let out a loud cry of victory.

Shelly tosses her racket to the ground in mock frustration and crosses her arms beneath her tits. She stamps her foot against the court, making the pure flesh of her breasts jiggle erotically. "No fair!" she cries. "The ball was totally out!"

You wag a finger at her. "Unh-uh," you say. "The judge says I win. Now take off those panties and show us your pretty puss." With a huff, Shelly hooks her underwear with her thumbs and pulls them down her smooth leg, her heavy titties hanging just inches away from your mother as she bends over. Your mother sighs heavily as the sight produces a fresh round of juices lubricates the inside of her tunnel, soaking her fingers. The flow gets even heavier when your sister stands back up, presenting her pussy and fully-shaved mound to everyone present.

"Happy?" she asks, striking a sexy pose with her hands on her hips. You just give a wide-toothed grin in response. "Now, what do you want for a prize?"

You look at her hot body and raise a finger to your chin as you consider your options. You circle her nude body, soaking in every inch of her perfection; from her plump, gravity-defying knockers to her smooth, round ass cheeks to her super-model face. All the pieces are magnificent, but when they're all combined it's mind-blowing. Stealing a glance at your mom, with her body still on full display, you really begin to see where your sister gets her good looks from. After two trips around you stop in front of her, staring at her chest.

"I want to fuck my girlfriend's tits," you say, reaching out to grab the objects of your desire, enjoying their velvety softness. Shelly arches her back, leaning into your hands with desire. Then she drops to her knees, directly in front of your mother and shakes her head.

"Boys and their obsession with boobs. Am I right, mom?" Without warning she tears off your underwear and your dick bounds into view with an energy that makes it wobble in the open air. A mini-orgasm courses through your mother when she sees your long rod. She's seen it once before, in a prior dream where she got to experience having it between her own enormous juggs and the memory of it floods her brain. She closes her eyes, riding the wave of **** pleasure and letting her body lose control. Her cunt tightens around her fingers and her nipples are screaming toward the sky, erect and aching.

When she opens her eyes again, you've taken a step forward and slipped your fat hog between your sister's/girlfriend's melons and your sister is lewdly letting her spittle drip from her mouth and into her deep valley, lubricating the snug tunnel she's created. Her hands are cupped beneath her breasts, lifting them higher and creating a single mass of fuckable flesh that makes your cock even harder. She tilts her head up while you tilt your head down, and you gaze at one another sensually as you begin plowing her chest, moving your hips with firm strokes.

You've dreamed about titfucking your sister's amazing rack--hell, technically you're still dreaming about it--but it feels better than you've ever imagined. The friction caused by rubbing against her creamy slopes is maddening and the more of it you experience, the more you want it. You push harder and faster, forcing your iron rod of a prick between her breasts until the tip breaks free to poke her at the base of her throat, where drops of precum form a small, glazed spot.

"Yeah, fuck my titties, boyfriend," Shelly encourages you through clenched teeth. Her words make your balls tingle, driving them closer to the point of emptying. "I love having your tasty cock plunging between my boobs, it makes me so fucking horny! It makes me feel like such a slut to have you use my body like this. To cum all over me and mark me as your own, personal whore."

"Yeah, cover your sister...I mean girlfriend with your sticky semen." You and Shelly are so shocked by the words that you pause for a second, both turning to look at your mother. She's sitting up in her chair, leaning closer while her hand furiously digs deeper into her pink slit. Her legs are spread wide and you can see every dirty movement. She's stopped fighting the unreal situation completely and is letting her own perverted lusts take over, masturbating while watching her children engage in ****. "So hot," she mutters. "Keep going, don't stop."

It's always a good idea to listen to your mother. But Shelly takes it a step further. As you start titfucking her again, she dips her head and finds one of your mother's swollen nipples with her wet mouth. She sucks on it, hard, and your mother squeals as another orgasm hits, draining your mom of even more energy. Your dick jerks as you watch your sister nibbling and licking your mom's prodigious chest.

"Girls and their obsession with boobs. Am I right, mom?" you ask. Shelly raises both her middle fingers at you but she never stops suckling. You laugh in response and pound away at her rack, driving down the home stretch. "Here it comes!"

You pull free of Shelly just in time to aim your first shot at her right tit, quickly followed by another to the left. Jizz pours from your cock as you unload every ounce from your balls, leaving the tanks empty and her breasts splattered with a perverted impressionist painting. You wipe the last drop on her silky skin, making even more of a mess, before stepping away, supremely satisfied.

Shelly releases your mom's nipple and straightens her back. Taking your mom in her arms, your sister pulls her forward until your mom's face is an inch away from your cum. Unthinking, your mom sticks out her tongue and takes a long lick across Shelly's semen-drenched skin, eating every white glob she comes across. It only takes a minute to clean all of your sister's boobs, but your mother continues for much longer, losing herself in her work. Finally, exhausted, your mother settles back into her seat.

Time for the dream to end. You smile at your sister. "I told you to trust me," you say. As recognition dawns in her eyes, you exit the dream and let it fade.
