Try to remove the underwear from the skeleton

MacKenzie tugged cautiously at the bra the skeleton was wearing. She could tell it was fastened behind the skeleton's back, and knelt astride the skeleton to reach round from both sides to unfasten it. She heard a click, and before she could react the skeleton's arms had flung themselves around her, in a gruesome hug. She pulled against the arms, but they were holding her tight, feeling as if they were joined behind her back.

Reaching behind back with with one hand Mackenzie tried to free herself. With her position, kneeling, bent over the skeleton, and now only supported by one hand, she lost her balance and fell on top of the skeleton. Her fall was broken by her breasts hitting the bra worn by the skeleton, which was padded, to make a more realistic effect, with air filled plastic bags.

McKenzie's relief at her soft landing was short lived. The air bags burst and MacKenzie fell down against the hard rib cage of the skeleton. The bra provided almost no protection as MacKenzie's weight on the rib cage caused the bones to shift, pinching her nipples painfully. MacKenzie quickly took her hand from behind her back and with her hands on either side of the skeleton's chest pushed herself upwards to free her trapped breasts. She could not get very far away due to the skeletal hug.

Being one of those people who give names to inanimate objects (if an animatronic skeleton is inanimate), MacKenzie had already started to think of the skeleton as Bonnie - from bony. Now she said 'Please Bonnie, it is lovely to meet you, and I am glad you want to cuddle, but I am naked, and don't want to be found like this, so please let me go'. On a more practical level, she had been kneeling astride Bonnie, and now MacKenzie gently lowered her hips towards Bonnie's hoping to make more space between her back and Bonnie's grasp so she could wriggle out.

Finally resting her hips on Bonnie's bikini bottom, MacKenzie had a surprise - Bonnie had a pubic mound! Then she had an even bigger surprise - there was a click and Bonnie's mound began vibrating - not in an unpleasant way - quite the opposite in fact!

The sensation might have been pleasant, but anyone could walk in, and MacKenzie was naked and the last thing she wanted was to be caught in flagrente delicto with a skeleton. Getting away from the feelings the vibrations were causing was more important that escaping Bonnie's hug, so MacKenzie tried to lift her hips back upwards. To MacKenzie's alarm this did not help her get away from her intimate contact with Bonnie, as the skeletal pelvis was rising as she did !

If MacKenzie had time to think about it she might have worked out that the panties had been concealing a hydraulic mechanism which made the skeleton sit up in a spooky way when triggered, and MacKenzie had activated it. The designers had not anticipated that there would be a girl lying on top of the skeleton when it happened.

Soon MacKenzie was doing a press-up on top of Bonnie, and could go no further. The vibrations underneath her became more insistent - taking MacKenzie right to the edge of an orgasm. She was no longer thinking about her situation, only the sensation between her legs, and then a cut-out activated, the vibrations stopped, and Bonnie, and MacKenzie, sank slowly back down to the table.

Unfortunately for MacKenzie, as soon as Bonnie was lying on the table the system activated again, resuming Bonnie and MacKenzie's erotic horizontal dance. MacKenzie was vaguely aware that to a spectator it would look as if she was humping the skeleton which would be mortifying - but this enhanced, rather than dampened her arousal.

On the third repeat MacKenzie did achieve her orgasm, leaving her gasping, but with a warm glow on top of Bonnie. A more considerate lover would have been content to cuddle a little at this stage, maybe chat a little - 'Have you been a skeleton long ?' and that kind of thing, but Bonnie was insatiable and MacKenzie had to go along with what she wanted.

MacKenzie gave up all hope of escape on her own, the orgasms kept coming, the only variation being that if MacKenzie was too tired even to support herself properly when resting on her elbows on the table, so that her breasts were pushing against Bonnie's ribs then her nipples would receive a painful pinch. She was even finding this erotic - having fantasies of being pulled by her nipples off to be Bonnie's captive.
