You want to escape, but you realize there will probably be guards, and you're just a weak little girl now. You look at Alex. He's a lean but sculpted mass of woflish muscle, built to fight. You need him. You have an idea.
"Alex, I need your help to get out of here, and I have an idea how you can."
He looks at you in confusion, but also in lust, as perhaps even unconsciously his hand moves to massage his cock, his thick, long, manly, beautiful-FOCUS. You snap out of it. "Uh, how?" he asks. "Even if I could focus, I don't know what I could do while lugging this thing around." he says with a nod towards his dick.
"I can handle that." You say. "Only...um, how much do you love me, Alex?"
"More than anything. I'd do anything for you."
"Good good...because...um...you'll have to do something extremely painful to help me."
"I'll do it."
"Ok. You trust me?"
"Yeah?"
He's so innocent. He might not trust you after this. "Close your eyes."
He does, and gritting your teeth at the idea of the familiar pain you're about to inflict, you wind up and... punch him in the balls. He falls to the floor moaning in pain. You rush to him and try to comfort him. "I'm so so so sorry. It's just the only thing I could think of that would turn you off for sure."
After several long wheezing moments he looks up at you with rage in his eyes. "You owe me so much for this."
The first thing your horny mind goes to is a promise to "kiss it and make it better" but you realize that would be unwise. "For sure, baby. Can you walk?"
"Do you mean within the day or just by the weekend?" He asks. At least he can make jokes. You look around nervously and notice 2 security guards coming towards you... "I swear this is so much worse than I imagined. The pain actually makes you nauseous"
"Alex, you have to get up NOW. There's security guards coming at us." He nods, and struggles to his feet. Soon the two guards are upon you. One was blonde, the other brown-haired
"Can we help you, uh, officers?" asks Alex, stepping in front of you. You notice that fear has somewhat cooled your arousal, and thankfully you seem better able to control yourself when horny than you could as a male, but you're definitely still one horny kitty, and your man stepping up to defend you is a turn on. Hiding behind him you think to put a hand on his back, but as much as you'd like to you reason you'd better avoid any physical contact.
"What are you kids doing? Why aren't you having sex?" demands the blonde security guard. You try not to laugh at the odd question.
"It's a public place, isn't it?" says Alex. "Would seem rather crass to have sex out here wouldn't it?" As if there weren't hundreds of teenagers fucking their hearts out around you so that you were all practically shouting to be heard over the chorus of moans.
"You need to have sex. It's a vital part of the experiment."
Alex stared back defiantly. "The lady does not wish to, and so she will NOT."
The security guard glared. "Listen kid, I'll be straight, either you can deflower your bitch now, or we take matters into our own hands, and you won't like that. Maybe we'll have a sample of 'er, eh? Since apparently you aren't man enough, though I guess that's no surprise given you were a bitch yourself a few minutes ago."
Alex went quiet then; quiet, cool...and deadly. You knew it was no act, either. Your apparently highly attuned feline instincts were telling you that the fellow predator next to you was going into kill mode. "Try it," he said, in a voice that seemed perfectly calm and matter-of-fact "and I will eat your heart." You knew he truly meant it. He'd literally tear the guy's heart out and eat it like a wolf. For a second the thought made you wonder what you had been made into, but there was little time to worry about it.
The security guards, unfortunately, had the survival instincts of rocks. "Take her." said the blonde. The brown-haired one moved towards you and you hissed and showed your claws, but before he even came near you there was a blur of black fur and both officers clutched their necks for a moment, before blood began pouring out and they fell to the ground. Alex stood over them, looking down with teeth bared, and indeed he even began to lean down towards them as if to bite...
"Alex!" you shout. He snaps out of it and looks at you. "We have to run!"
And so you do, and though other resistance is encountered, you find it relatively easy to escape. There are many guards, but they are lightly armed, and apparently they hadn't expected your animal traits to give you borderline superpowers. You find that you are flexible, nimble, a better gymnast than any olympian, able to leap several times your own height and climb buildings with ease. You're not such a weak little girl after all, though perhaps still weak next to Alex, who for his part was a killing machine of a different kind, fast and tough and deadly like the species whose traits he had borrowed, only more so.
Both of you are fast, and your instincts teach you more about hunting than your pursuers will ever know, so you throw off their feeble attempts at hunting you and soon find yourselves in relatively safety in the woods.
