Try to run

You don't know what's going on, but there's something distinctly creepy about this girl - golden glowing eyes aren't exactly usual. You take a step back and turn to run, but she grabs you by the shoulder and slams you, with terrifying strength, against the wall of the blue police box.

"I'm afraid not," she purrs, smirking at you, "I can't let you leave just yet. You see, I swallowed the vortex energy, and that's a really big meal... but it just made me hungry for more."

One arm either side of your head, palms flat against the blue box, she grinds her hot curves against you, causing your dick to stiffen involuntarily as she continues.

"You're full of energy. Delicious energy. Millions and millions of potential lives. All swimming around right... here."

Moving so fast it's not even a blur, one of her hands whips down and grabs your balls, squeezes them gently. You gasp and your cock grows even stiffer.

"Each little sperm is a potential child, a potential life, full of all kinds of adventures... and I'm going to feed on them. I'm going to drain. You. Dry."

Nibbling on your jawbone, smiling at your gasps, she goes on.

"I'm not unkind though... You're being good to me, giving me such a nice meal... I'm going to let you decide how I drain you. Would you like me to just suck them right out of you... or do you want to be... milked?"
