Let her shish-kebab you

No, why ruin a perfectly good cock by shrinking it? You toss her wand far enough that she wouldn't be able to grab it, just in case. You bite your lip as you look at her. Sabrina is grinning like a mad woman, fully aware of what you want. But where to start? There is no way you would even be able to swallow it, and it'd certainly split you in half if you tried to take the whole thing. It would require creative thinking. Maybe just the head would be enough to get you off without ruining you? You nod, sitting on the cock like on a tree branch. You grind your wet snatch along the shaft up and down. Your lust builds within you, and before long you really need it inside. You stand up, propping her cock into an upright position, and start to lower yourself down against the head. You whimper as your fingers spread your pussy as wide as it can get. There's a few long moments of struggling and then...

...you gasp as your snatch gives in, and with a lurch it enters you proper. Oh my god is this thing big. You let a silvery drop of drool drop from your lips, lost for a second. You grunt and then start to move, your hips going up and down but your pussy still stuck in the same place. The infected spectators go wild, hollering and moaning and rattling the bars. But they're almost inaudible for you, in the background almost unnoticed.

Sabrina grabs you by your ankles, and begins to pull you down. You yelp. It can't go any deeper, it can't! You're already stretched to your limits! She cackles in delight.

"Oh my goodness, ladies and gentlemen, this is not something you see everyday! The woman in the ring has attempted to take on Sabrina's infamous giant whammy; none too many have been able to completely take it without being left split open like a watermelon and a sledgehammer on a date!... did I really write that? Rough. Anyway! Watch in stupefixtion!"

You heard none of that. Well, you heard it, but you aren't able to process it; currently your groin is being opened up by something way too big for you. It's quite painful, but strangely good too, in a shameful, mindless, masochistic sort of way. The cock head appears as a large bulge through your stomach. You drool and start to gargle and groan, your eyes watering up. Sabrina just continues to pull on you, inserting more and more into you. She stops, and lets you slowly slide off, before cruelly pulling you down once again just before you escape. You started off in control, but it seems you bit off more than you could chew. Now you're just a big, glorified fleshlight. A body wrapped around a tree log. The head mashes and pushes against your cervix. It's all too much, the stimuli is just too much, everything is just too much! Your head spins as Sabrina picks up the pace, tugging you again and again, the forceful nature of it all building up... and you black out.

"...Well that's dissappointing folks, Hector the Beastmaster falls in the arena for a second time! Hector, step up your game, or you're out of a job!" The woman behind the PA shuffles through some papers. "We do have a second act though, and this one does not dissapoint; ladies and gentlemen, it's Sabrina the Magnifique!"

The portcullis opens suddenly, making the new challenger jump in surprise. The infected cheer wildly; they all know who it is. Sabrina stands there like a silhouette, her face mad and grinning like always. You're there too, tied to her front like a forward facing backpack, your arms and legs wrapped around her back. Her gargantuan cock is in your anus, running up through your body, giving you a second spine. Your cunt is gaping, almost two fists across, oozing an honestly ridiculous amount of cum from your ridiculously inflated stomach. What a first impression you're giving. You grunt and moan like a stupid animal with Sabrina's every step, shaking up and down, drooling.

You try to say something, a warning to the challenger, but it comes out too quiet and garbled. All they hear is a couple of pathetic whimpers. Sabrina grins, petting you on the head. She kisses you on the cheek and then focuses on her next victim.
