What’s your next move?
Titfuck Sierra
Your mind floods immediately with thoughts of diving straight into Sierra’s mouthwatering, deep, juicy cleavage, using it like you would any pussy — thrusting along its moist walls until you bust all over her face and chest. It’s tantalizing invitation stares you right in the face, her sports bra creating that perfect “V” to show you just enough of what you’ve been missing.
You feel her warm hand caress your cheek, and your hot model AI-O steps closer to you: “I can tell this is what you want, isn’t it… my sweet boy?” Sierra hums with a soft honeyed melody. “I know because of my heartbeat sensor for you going positively wild!… and well, I also see that little guy getting to be a big guy in your pants… why don’t you show him to me, sweetie?” As she speaks, you feel her hands move along your body, the silken touch of her synthetic skin sending sensual sensation through your entire body. You shudder at the next words that leave her lips as she leans in, the hot air of her whisper just mere inches from your ear: “I need that cock in between my breasts. Right. Now.”
Hearing that is enough to simply send you into an autopiloted mode. With haste you yourself have never felt before, you shuffle your sweat pants off, letting your cock flop out in the open air of the dorm apartment. It twitches and throbs with anticipation only known to you from the sight of such glorious boobs, and you look up to check Sierra’s reaction.
“Good boy.” She purrs, and with a swift motion she places her hands on your chest and pushes you onto the couch of the living room. You stumble back and fall onto the soft cushions, stunned and half naked. Holy shit, she’s strong. Whether that be from the mechanics in her body or the testosterone from her balls talking, you can’t place where her otherworldly strength comes from. As she kneels, descending to your level, Sierra tugs at the hems of her sports bra. “These girls need to be let free,” she coos as the movement in the tight fabric makes her imposing breasts jiggle for you. “You know, it should be a crime to keep the girls in for an extended period of time — even though it’s only been a couple of minutes with this pesky sports bra on. Let’s fix that.” With a matter-of-fact attitude, Sierra moans as the tugs on her clothes become more frantic, her tits entering a whirlwind of swaying and bouncing as the sports bra struggles to contain their size. The sound of stretching — almost like flesh being molded — hits your ears in tandem with Sierra’s moaning as her breasts begin to inflate larger. Not that they weren’t massive before, but this new level of obscenely erotic body manipulation can now smother your face with just one breast. The fabric of the sports bra begins to strain and groan with the increased load put behind it, and Sierra looks up at you, checking to see that you’re watching like the good boy you are. With a grunt her hands grab at the sports bra one last time as she tears it off with such graceful ease, releasing her breasts out into the open air once more.
“You like what you see, don’t you sweet thing?” Sierra sways gently as she quickly takes up her massive mounds in her arms, and massages them with lustful desire. Her previous F-cup measurements are a thing of the past, and you can tell that she’s eager to do even more, if you asked. “Mmmm, these girls are bigger and much better than before, huh? I think we should be in the I or J-cup range with them, though that’s on the smaller end… Hehe, if you brought me back for the Terran Christmas, I don’t think one of those winter sweaters would even hide em now!” Sierra continues, becoming ever-more aroused. You spot her bulge underneath her yoga pants, writhing, growing — almost like it’s begging to be let free. She catches your stare, and clicks her tongue, “Ah ah ah, eyes up here, naughty boy. My tits are where you should be staring — we’ll get to ‘her’ later.” Sierra finishes kneeling, her breasts perfectly level with your twitching shaft. She licks her lips, moaning softly as she inches closer to your cock. “He seems so eager, master. Why don’t we just…” her voice trails off as she springs forward, covering the last couple of inches in a flash. Her tits instantly wrap around your cock, the warm flesh engulfing your entire shaft as she giggles with glee. “Oh my god, sweet boy, you’re hard as a rock for me, aren’t you? It feels so good and hot, the way it’s pulsing and pumping for me. But I guess it’s time to get pumping for you!” Your AI-O takes her time to toss her luxurious red hair behind her, almost blinding you with that stunning face card, revealing the rest of her porcelain tan torso. She smiles, her eyes never leaving yours as she begins to move. You can tell behind those eyes that she has secrets that’ll make each and every experience just perfect, and you’ll just leave her to surprise you every step of the way.
You can’t help but moan when Sierra’s cleavage begins moving around your hard, long, shaft, and you grab at the couch cushions to avoid being sent to heaven from this insane amount of pleasure. Coupled with soft coos and giggles from your stunning model, the soft, gentle sound of wet stroking spreads out through the apartment, her tits effortlessly working precum out of your tip. As if this couldn’t get any better, the lubrication in her deep boob-valley increases as her breasts begin to gleam with a shiny substance: sweat? No, natural oil begins trickling down her collarbone and into her cleavage, increasing the slipperiness and sensation tenfold. The wonders that keep coming from your new acquisition thrill you, and urge you to buck your hips just enough to make Sierra squeal.
“My oh my, darling! Someone’s eager… here, let me help you drive that juicy cock of yours into my tits.” The big-breasted redhead begins to stand, but this time with her arms under your lap. She lifts you up like a forklift, easily picking your entire body up like it was some bags of groceries. Pirouetting with the lightness of a ballerina, she sits down on the couch — effectively switching positions with you, leaving you straddling her abdomen. Before you can admire the way your shaft looks on her, the tip just barely brushing the underside of her breasts, you feel her hands grab your toned hips with a sexual fervor only known to a nymphomaniac. “Come, now, my sweet boy, fuck my titties just the way you’ve always wanted.” Without pause, Sierra pulls you in, plunging your cock into her cleavage once more as she leans back and moans at the sensation of your shaft against her skin. You pick up a steady rhythmic thrusting, aided by her guiding hands, and feel that similar lubricant bead up on her skin again. Your busty model falls into a trance-like state of pleasure, moaning sweet nothings as you pound her soft breasts. Interspersed with her soft groans come a few words that you barely perceive: “Ahh, yes… cock… between… huge fucking boobs… tighter…” You’re left confused, as the panting from both of you fills the room. All of the sudden, though, her pec muscles flex inwardly, causing her boobs to surge around your cock and wrap around them, tight like a vice. Shockwaves of pleasure jolt from the tip of your cock up your spine, and you instinctively thrust harder as her breasts seem to move on their own, stroking you as you plow into her hungry cleavage. She seems to notice this renewed pace, as she snaps out of her daze and screams: “Oh, fuck yes my darling! Pound these tits like you want to cum forever on them. Fuck em nice and hard, I want to see every drop of cum on my tits.” She chuckles as you greedily hump her cleavage, her voice slightly deepening as her eyes pierce into you with sexual fuel. “Oh, you like how the girls can move on their own? Press into you without me having to move my arms around them? Well, it is a thing that women can naturally do, but for an organic to do this, it takes years of chest muscle development. For me, though…” She pauses and lets loose another tight squeeze around your cock, “I can make this cleavage as tight as any pussy you could fuck, and I wouldn’t have to lift a finger.”
You moan in sweet release, your cock free to pound away at her tight valley with reckless abandon, and all the while she can service you like a pro. You’re all too pleased with your thrusts and grunts that, when you start to hear a ripping sound behind you, you don’t correlate that to the increasing frequency of Sierra’s pants and moans. The familiar squelching and stretching sounds grow louder and louder, matched only by your model’s lewd groans until she lets out a **** cry: “Ohhhhh, you’re being such a good boy, fucking my tits! You really did it now… look behind you and see what you’ve done to me.” You shoot Sierra an inquisitive glance, only to be met by a feral stare, full of sheer desire. You turn your head around, leaving your cock buried deep within her breasts, only to be met with the last few rips of her yoga pants. Sierra’s earth shattering cock finally escapes from its confines, now towering behind you at 3 feet long and thicker than your leg, looming over you like a juicy, dripping, veiny ship’s mast. You hear her chuckle from behind you, and shivers are rocketing throughout your body as the 36” of horse meat pulse and spurt precum. “It seems like my other girl has come out to play… I tried to keep it packed away for as long as I can, but the yoga pants just simply wouldn’t do!” She chuckles once more as she touches your chin, guiding you back to her eyes: “Don’t worry, my sweet boy, good boys get to finish. Now pound and cum on my titties like I want you to. ‘She’ll’ watch.”
Spurred on by yet another enticing command, you place your hands directly atop Sierra’s nipples, your palms squishing the rock-hard protrusions as she mews and squirms in pleasurable reaction. Slippery thrusts and heavy pants pick up once more, and soon you’re on the brink of blowing your load. “Oh, you’re almost there! Good boy! Well now, are you going to shoot your hot cum all over me? If you do, I think there’s a present in store for you…”
She needn’t say any more. With a final, crowning thrust, you feel your balls tighten and churn as you unload your cum, splattering a healthy amount directly onto her neck and chest. She lets out an elongated moan, and her legs shake uncontrollably underneath you. Involuntarily thrusts take you on a bouncy ride as she rewards you with a geyser of cum, spraying every which way from her massive equine cock. The fountain of jizz rises up to 5 feet up into the air, pouring down on the both of you as her whole body shudders. “Oh, yes! I’m cumming so much from you tittyfucking me!! Oh it feels so fucking goooooood…” As you come down from your orgasm, you notice that Sierra continues past your climax. Showering with cum, the apartment begins to form a pool of her hot sticky fluid, with rope after rope cascading down the walls, windows, and furniture. Minutes pass, and the entire living room is drenched in her sticky, hot seed, her soccer ball sized nuts finally losing steam. “Oh my god… you’re such a good boy, fucking my boobies like that. Look at how much you made me cum from doing that! Mmm, Steele Corps material, indeed. Now, mind if I give you another reward? I can of course be the gift that keeps on giving…”, your model’s eyes glimmer with a mix of adoration and shared lust.
Knowing that this might involve her cock, do you accept? Or do you want to try and spin the narrative, and do something else?
Do you allow her to give you another ‘reward’?
