It gets worse

The gel-coated tentacle creeps down your body again. It very carefully traces the outside of your labia, touching nothing else, while another tentacle pushes its way into your cunt and... sits there, doing nothing. held up by your arms and legs the way you are, you can't move to get any stimulation on your labia or cunt, but the suction cups on your breasts are working overtime, throwing ripples of pleasure and pain through your body.

Another tentacle forces its way into your ass. It thrusts in and out roughly in a way that might be pleasurable if it were in your cunt, but that tentacle remains frustratingly still. The one in your ass is excruciating.

The gel tentacle traces across the bottom of your feet, making them hypersensitive, and then brushes in tiny circles across one, then the other. It's difficult to remember how to breathe.
