Robert can barely take his focus off of your glossy rubber posterior, his eyes solely fixed on your cheeks as his bulge squeaks with every pulse it makes between your cheeks. His gaze stays fixed on it as he can feel his fused forearms fondling you from inside of your rear. Its as if Roberts forearms are now your ass. His hands feel like they are lost in deep rubber void, pulsing with your every heartbeat somewhere inside your pelvis. Robert tries to wriggle his hands much to your glee as your bulge pulses and your ass cheeks quiver, causing you to moan and yelp in excitement. Your so lost to the feeling of being groped and molested from your entire pelvis your drooling now, and your rubber ass and crotch slowly secrete rubber polish-like lube, making your rubber squeak louder on Roberts struggling to expand budge, as he no longer had a dick like you do, it was just a bulge of hyper sensitive rubber like yours.
Robert tried to pull his arms out of your ass, but only foisted your rear into his pelvis hard, his bulge squeezing into your anus-less crack hard with a loud tight rubber squelch. You scream for him to fuck you harder, you kick your legs against the floor pushing your ass even harder into his now shiny lubricated bulge, your rubber squealing in delight. Robert tries to brace himself against the bed and pushes back on your ass. Now panting and wheezing. You want him to fuck you so bad now, but without an anus and with him without a dick all you can do is rub rubbers harder, you think about wanting him in deeper, or perhaps you onto his dick harder, and Robert pushes himself onto your ass as hard as he can, the rubber sings and stretches, then suddenly you feel your ass give way, like a liquid filled balloon that popped and a huge amount of pressure inside you is released, your rubber pulses violently in your crotch as you hear the sound of deep latex sucking, like how it was when your underwear fused to you yesterday. But something big feels like its being vacuumed up deep into your rubber cavity, you feel your ass is sucking down on Roberts Bulge, or perhaps hungerly slurping it into your crack. The gooey cavity of your ass feels like its sinking into his bulge and the rubber of his loins.
Robert Screams in sweet release as he looks down to see your ass crack suck down on his bulge and disappear into your rubber, he convulses with excitement as your ass cheeks seem to melt and deform, sucking down on his groin like a goo, but somewhat retaining the shape of your butt, your latex goo butt quickly stops sucking on him as he is more than elbow deep into your ass and now cannot feel the difference or even the gap between your rubber ass and his groin. Tries to move his hands inside your groin only to his pleasure as he feels his hands now inside his own rubber crotch, as if he is jacking himself off now. He can feel the pulsing and convulsing of your rubber crotch as if it was his own! He pulls his arms toward him as if he was to try and squeeze you toward him again and you fall hunched over, your ass exposed to him and he falls off the bed too, catching himself on your backside. Robert continues to pant as now he's stuck jacking himself off inside of your ass, or is it his crotch?
You feel Roberts rubbery groin sink deep into your ass cheeks before the cavity-like feeling fades and your ass begins to feel of solid rubber again, but now you feel like your ass ends where Roberts is. You can feel Roberts arms have also sunken deeper into your ass, errr... his crotch? Your ass feels like its now Roberts crotch! You can feel his convulsions as well as yours now, Then Robert makes a sudden jolt and it forces your legs to bend, folding you into a fetal position and your face smacks the floor, then you feel Roberts weight fall on top of you and your rubber cheeks Roberts Crotch deeper into them with a deep Stretch like suck... Your rubbers then convulse again as your rubbers cum inside each other... Still providing you both no serious release... Only sucking your rubbers deeper into each other as you struggle! Something in your mind tells you that It won't end well for you if you let him suck you even deeper into his groin without putting up a fight, yet the thought of being consumed by his rubber and sinking deeper into his crotch is beyond pleasing... Or perhaps you could try to suck him into your ass, and have him sink into your rubber instead, so he can please you even further and jack you off from the inside...
Robert feels like your ass is still continuing to suck down on his bulge and can't get off of your back, his arms are too deep into your ass cheeks now to ever pop free, the more you suck on him and draw him into your ass the more and more pleasure he feels, but that faint worry in him is building that you won't stop pulling him in if he lets you, though the thought of being sucked even deeper into your shiny rubber ass is extremely temping.... The thought then also crosses his mind, that if he can suck harder than you... He can make more of your ass be absorbed into his groin while he jacks himself off from inside you...
So... Who will win? Are you going to be sucked into Roberts rubber groin? Or are you going to pull him into your rubber ass?
