*Cue 'Careless Whisper'*

Any attempt at protesting is immediately silenced as the goo girl kisses you again, forcing her tongue into your mouth.

You give in to the kiss, not bothering to struggle as she explores you. Everything she touches begins to tingle, and her taste is... surprisingly fruity, like that exotic 'punch' drink you sampled at the last tournament.

Her saliva (or is it goo? Do goos even have saliva?) starts to pool in your mouth, and you reflexively swallow it down, feeling it give a pleasant burning sensation as it travels down into your belly.

You let out a moan when she pulls away. Your heart is pounding, your breathing is loud and rapid, and your head is starting to feel foggy.

"Since we're gonna do it, I thought, like we should make it extra special..." the goo says with a smile.

You feel the heat spreading out suddenly from your stomach, to your arms, legs, face and most importantly, your nether regions.

"What... what did you...?" You struggle to say between gasps before the slimy girl shushes you into silence.

"Just let it do its job," she whispers.

You feel your strength leaving you and your skin growing more sensitive with each beat of your heart. You start to notice minute details about your body, like the way the slime currently enveloping you is not remaining static, but is constantly, if slowly, moving about you like a stream of water. The feeling is especially noticeable along your erect nipples and clit.

"You're feeling it now, arentcha?" Giggles the goo. "Well you're really gonna like this..."

She closes her eyes and takes a deep breath. Before you can respond, you begin to feel a strong vibrating sensation along your shoulders and neck. You coo in pleasure as vibrations continue, erasing all feeling of tension in your muscles.

Then other parts of your body start to feel similar sensations. You feel them at your hands and feet, and have to struggle not to laugh at the ticklish sensation. Then you feel one on your belly and lose all concentration and start giggling.

"Somebody is sensitive," says the goo as she stops the vibrations.

You let out a mixture of a whine and sigh as the sensations stop, but before you can do anything else, the girl takes an even deeper breath and begins again.

This time it's even more intense, and worse still, you can feel it creeping towards your breasts, thighs and ass.

You squeak when the vibrations finally reach your nipples. That's quickly followed by a squeal and a moan when it gets to your ass and pussy.

You close your eyes and bite your lip as the vibrations get more intense, feeling completely helpless in the goo's clutches as your first orgasm of the night arrives.
