It was watching with all eight eyes the growing flesh of David's cock. It no longer seemed to care about the view-screen. It whispered something, and the alien controlling the camera stepped aside as the big one took control. And this cause/effect was not missed by the tallest alien. And his dick began responding involuntarily. With each adjustment, the sheath nudged his prostate. This wasn't a straight-shot tube like the throat, but a winding trail. But as they continued the probe, they had to constantly re-position the sheath. A brief sensation of motion was all he felt, but he knew the camera was sneaking a peek at his intestines. He felt it slide in about 2 or 3 inches, resting bluntly against his prostate. Yes, it was being eased past his sphincter, the same device. He flinched as something else warm touched him there, knowing what was coming next. Then he felt something wet and slick applied to his asshole. They looked around for a while, then withdrew it. He watched as best as he could, seeing how the picture changed as the camera reached his stomach. They were apparently probing him, maybe with a camera, as he could see out of the corner of his eye a screen with a moving picture of what he imagined a camera would see if it went down a throat. He felt a slight sensation as something else emerged from the device and slid down his esophagus toward his stomach. It pushed further, making him gag, but after it stopped moving, he got used to it. It was pushed in until it reached the back of his throat. He gave up, knowing that eventually they would f orce it in.
Insistent fingers began pulling his lips apart, clicking the device against his teeth. It was only about a half inch in diameter, but he still resisted. One of the aliens placed a small cylindrical device at his mouth, and began trying to insert it.
