Down her throat

You smile down at her. “Okay, Power Vacuum, I’m about to cum. Are you going to suck it all down like a good little super whore?”

Affirmative sounds come from the throat imbedded on your cock. You grab two fistfuls of blonde hair and shove her head down on your cock. She could easily resist, but she never will. You unload your balls directly into her throat. Her throat muscles must also be super, because they work your cock hard, milking every last drop from you.

Despite cumming, you’re so turned on by the experience that your dick is still semi-hard.

“Keep sucking!” you yell. “I know you can go hours without breathing, so just work my cock with that super throat of yours.”

You’ve softened enough so only the tip of your cock is still in her throat, but she manages to clamp down on it. Her expert throat and tongue work hard. Within seconds you start expanding again.

You smile down at her evilly. “I want to see those mega-titties!”

Power Girl grabs fistfuls of her uniform and starts ripping off patches of it. Every time a new part shreds off your cock twitches a little. Soon her huge breasts are swinging below you.

“Play with your nipples as you deepthroat me, bitch!”

She tweaks her nipples and moans on your cock, clearly she’s very horny. Seeing her completely at your mercy and very frustrated is a huge turn on. The pressure builds in your balls again, but you decide not to warn her this time.

You spurt down her throat. Power Girl seems to actually get off on it. Her back goes rigid, and her hands squeeze her breasts hard. She’s having an orgasm from you cumming down her throat! This time she sucks you until you are completely limp.

“All right, that’s enough of that,” you say, pulling out and zipping up. “Grab the jewels and fly us out of here.”
