She reached for the item. It was cold to the touch and very, very smooth. She slid the domed end up against her open cunt and gasped a little at the coldness. She wriggled a little to get in position and started to move it in. The dome easily parted her lips at first but the blunt size of it quickly faced resistance. There was a little pain as the entrance was forced wider than she had gone before, but once there she was surprised at the agreeable strength of the sensation. So far so good, the width was possible, now for the length. She placed both hands on the end and started to move it further in, a little at a time stopping and relaxing each time. Quickly it moved past her pubic bones and she found the resistance slackened, allowing a little more penetration each time. Soon it was almost all in, she could just see the black disc of the base showing in the mirror and hardly anything at all as she looked down on her mound. Would it come out again? She gathered her muscles and squeezed, slowly at first it began to reappear, then faster until, with a rush it slid to onto the sofa between her legs. She paused for breath then started again.
It slid in more easily this time and she quickly had it inserted all the way to the rim of the base. This time she pushed further and watched fascinated, even a little horrified, as her cunt started to swallow it, gradually the black disc was covered until with a final gulp her muscles spasmed and it settled itself up inside her and completely out of view. Amazed, she stared at herself in the mirror for some time.
Eventually she started to close her legs, cautiously at first, but finding no problems soon fully. Then she got to her feet and tried a few steps. The sensation unlike anything she had experienced. It was strong and very intense in an odd way, but it was manageable and not painful. She walked up and down naked in front of the mirror watching herself. Would anyone notice anything in her movements? If so, that could spell disaster. After a while she satisfied herself that all was well and the sensation even started to feel more normal.
Eventually, she walked to the bathroom and cleaned herself up. It wouldn't be good to smell too sexual, the men or the guard dogs would soon pick that up. She applied more deoderant than usual, then went into her bedroom. She picked out her best panties and slid them on. At least she would be well dressed whatever happened...
