Suddenly there is a loud thump from behind you. The original dildo thumping against the bathroom door. You jump up in surprise, and seem to startle the ponderous penis in front of you. Like a massive anaconda, the giant dong draws itself backwards, and then raises up to the ceiling. Its monstrous length lunges with impossible speed and it rapidly begins coiling its length around you. The unnatural dexterity of the rubbery latex is undaunted by your struggles. Instead your thrashing and wrestling only seems to pleasure the perverse beast, thick sticky and musky pre-cum dribbling from it's a thick tube-like protuberance.
Despite it's mass and size, the devilish dildo is incredibly strong. In a few seconds the contest is over. The evil equine latex is unyielding, and with unholy speed, your arms and legs are quickly pinned in it's coils. The surface of your captor is cold and rubbery, simultaneously life-like in detail, but devoid of genuine life. Sculpted synthetic veins and wrinkles stretch and contort against you. It's pair of hard rubber testicles sit impossibly heavy on your shins. Utterly at it's mercy, the giant equine cock rears above you. Its eye-less head looks you in the face seemingly satisfied with it's capture. The protruding tube-like urethra, big enough to swallow a soda can, seemingly yawning it almost seems to be mocking your struggles.
The free length of the dildo turns away from you. It seems to be investigating the crotch of your jeans. Although it's girthy coils conceal your vision, you can feel it's giant 'mouth' probing at your crotch. The dildo's muscular movements nuzzle it's cock-tip into you, soaking your genitals through every layer of clothing. Cold, viscous and musky pre, seeming to seep into your very bones. Suddenly there begins a strange gurgling noise, like a grotesque swallowing. Like some giant sea-cucumber feeding, you can feel its urethra seeming to engulf your enrobed genitals. You try to scream, but it's caught in your throat as thick rubbery coil squeeze against your chest and neck, driving your jaw tight. Grotesque slurping noises vibrate from below, eldritch sensations as the maw of the dildo seems to suckle upon your junk despite your cloths. Suddenly it feels like your cloths give way. The gurgling noises change in pitch and volume to sucking noises as your flesh seems to spring free into the 'mouth' of your captor.
The giant dildo is soon sucking on every square inch of your package. Cold stick latex clinging to every single centimeter of your dick and balls. The massive tube-like process quickly engulfing every pore, every wrinkle and vein. Fear has left you flaccid, but not for long. Despite the cold and rubbery texture the 'mouth' of this thing, it slowly seems to warm as it teases every nerve, literally sucking arousal into you. The latex only yielding it's suck-job tightness to draw more pleasure into your genitals. The evil equine urethra does everything, it sucks, it undulates, it vibrates, it stretches, it teases, it... worships.
You cum quickly beneath the alien expertise of the giant dong. Every single drop of your seed is sucked down by the unsatisfied maw. It's unholy suction is relentless, the evil alien dick vacuum seemingly unwilling to let you go soft. Pleased by your load, it loosens it's coils slightly, and it props your head up so you can watch as your comparatively tiny offering is suckled down it to it's soccer ball sized nuts. Your post orgasmic bliss marred by the giant dildo's grim resolve to continue pleasuring you. "Hnnng...what...why...please...stop....ahhh.....hnnnng" as it feels like your very words are being sucked out though your dick. You cum again, the second weaker load does little to please the evil dildo.
