Surprisingly well (Fem)

You tug at the extra arm at your chest. The sensation it gives you are like bugs crawling under your skin; it's just unnatural! Sabrina taps her hat once more and another arm sprouts from your body, this time you feel it coming out from your tailbone, writhing about like a tail, it's fingers creeping under your clothes towards your snatch. Your clothes begin to stretch and tear, soon your clothes will pop off you in pieces!

But you freeze when the fingers of the second arm start pleasuring you. It feels creepy and wrong, like a stranger's arm touching you on the bus. You buck your knees inward, and you're stuck in place, unable to move, your arms struggling to wrest control of your private bits, but the familiar feeling of pleasure seems to be winning your body over. The groping arm kneads your breasts and the other arm is stretching your snatch out invitingly, seemingly for a third guest. You wonder why it's doing that, and as you look at Sabrina you get your answer... She taps the hat one last time towards you, and four extra arm sprout from your back, two suddenly grabbing your arms and locking them to your back, and the other two press their thumbs against the back of your knees, forcing you to kneel. Your shirt just rips into tatters from the extra bulk and falls to the ground, revealing to the audience your breasts; they hoot and holler at the sight of them. But you aren't the only one with something 'extra' now; Sabrina shows off her newly sprouted dick and taunts you by thrusting her hips forwards. It's... It's... It's huge! It's gargantuan! Comically so, no one would be even able to lift such a thing!... And yet, poised from Sabrinas crotch is a cock so big it reaches past her breasts, thicker than a tree trunk; with a set of testicles the size of teapots to match! There's no way it would fit in you; it'd leave you a mangled mess! But she seems 100% serious and determined to use it on you.

She begins to walk closer to you, each step with the grace and posture of a ballerina, but all the while with an evil, maniacal grin of a person not quite fully in control of their own mind. You can't help but sob, begging her and anyone else who could interject, but all fell on deaf ears. You even beg your extra arms to let you go...

...Which to your surprise works! The other arms let you go and just sit there drooping. If they listened to your request before, perhaps all along they were within your control? You concentrate, trying to gain control of the extra appendages... Yes! It worked! It makes you feel quite queasy to suddenly be able to control this many arms, and your head pounds loudly in your skull from all the extra stimuli it has to process, but it's bearable!

Sabrina notices only too late that you've freed yourself from her grasp, and she moves her wand to the hat, but she's not quick enough. You tackle into her, knocking her over, her wand and hat flying out of her hands and into yours. Without letting her grab an opportunity to do anything, you pin her hands and legs with your extras to the ground.

"Now isn't that ironic! Using those extra grabbers Sabrina gave her against her! What a turn of events! Though I must say, I was kind of looking forward to our guest being played with, but oh well! Perhaps we'll still get a show yet!" The PA woman's voice seems extra cheery than before.

Sabrina seems extremely surprised, yet she doesn't look worried; she almost looks happy that you've pinned her to the ground! She only giggles girlishly, grinding her gargantuan cock against your body. Maybe with that wand of hers you could shrink it down to a more manageable size, but you must say now that you can think about it, getting shish-kebabed by such a monstrosity turns you on a little; if she were gentle of course, it could be a fun new experience for you! Of course, the most sensible option would be to just knock her out and get out of here.
