The device waited in front of me, large and automated. It whirred to life and started moving. I tried to move my hips away, but only managed to arch my waist upwards a bit. It was coming out of the machine now - smooth, black, nondescript, and the dimensions of a man's cock, for exactly the reason you'd think. I could see as it made its slow way between my spread legs that it was oozing a clear and viscous fluid from the small hole at its rounded head.
It got closer and I tried to contort myself, twisting my torso as much as I could. Still it got closer to my exposed and open pussy, and finally it pushed in between my inner pussy lips to press precisely against my small vaginal opening, which twitched open and shut against it involuntarily. The appendage paused there, and I could feel the cold gooiness on it. The machine whirred again, and another mechanical arm reached over to me. This one ended in a small plain object, and it came to rest atop and cover my vulva, above the other appendage pressing gently into me. I whimpered a little, helplessly.
Now in the right place, the object pushed down to apply firm pressure into my upper vulva, with a bump on it pushing even more firmly against my clit and making me clench my muscles. It turned on, and buzzing filled the air as it started vibrating at a low level. I shifted uncomfortably. After a moment it started feeling nice, making me even more uncomfortable. The other thing was still pressed lightly against my hole, every little movement I made against it reminding me. I clenched my hands as the vibrations increased in intensity and started coming in pulses. The buzzing was insistent again the smooth damp flesh of my pussy, sending little jolts through my clit and up into my body.
The vibrator kicked up another notch and I gasped lightly, biting my lip. I felt my vagina spasm open in response, like it was asking to be filled. I bit my lip harder, disgusted at myself. Like it had been spurred on, the thing waiting at my vaginal opening began to move again. It felt like it was oozing more as it pushed against me slowly. It was too big to go in easily, but with the help of the lubrication it was producing, it managed to breach my hole. It pushed inside my vagina as the vibrator continued. It moved slowly, and though it was uncomfortably large it was going in smoothly and relentlessly. I moaned a little in protest but I couldn't stop it. It buried itself inside me, and when it had penetrated as deep as it could, it stayed there.
