Finding a Way Out. At First...

You didn't care what Mercy was doing, but you made your glasses disappear and started looking for a way to get to the surface, since you still can't teleport on your own. At that moment, guess who aimed a pistol at the back of your head? "Here's the deal: you and I are gonna do the nasty right here and now, or I'll make a third eye for you." Mercy cocked the hammer, priming it to fire. "Get me?" In your mind, you had just about had it with Mercy double-crossing you, and now that beefy villain was on the loose!

You took your time answering, trying to figure out a way to get the heck out of dodge... Just when she was about to shout irritably at you, you answered.

"Fine. But I won't enjoy myself." She only put her gun away after you remove your pants and underwear. Your dick was flaccid at that point, but Mercy took off her lower garments, as well. So she took your hand forcefully, place it between her legs, and had you rub your fingers upon her pussy lips. It was kind of damp to your touch, while she cupped and rubbed your length from the bottom only.

The sensation was a little different from what you were used to, but that wasn't to say you didn't enjoy it. Secretly... The two of you were just priming each other, so that you, at the very least, could get it over with. Mercy, meanwhile was a bit preoccupied with your erection, how it didn't seem longer than her boss's, but still.

It was... compelling.

She still had your dick in her clutches, walking to a wall and positioned herself against it, ready to take you in. "My eyes are always on Lex..." she said softly, "but when I watched you battle, watched you fuck your way to get to this point, I wanted to weigh a new option for considering..."

"Just stop talking." You plunge right into her cunt, grabbing at her hips to steady yourself and you wasted no time in hammering your groin against hers. Your meat slid and out of her rapidly from the slightly angry sex you gave her. Not that you gave a flying rat about the effect(s) you had on her, but she was enjoying herself more than she thought... Her moans were fairly audible to you, paying attention to only get her off. You got upset, spanking her ass cheek harshly when you realized something: she was keeping you here!

You paddled the other cheek just as hard, as the first smack cited a gasp from her lips, and now the second made her groan contently on a low tone. "I've been a bad girl... Punish me..." Hearing her talking dirty as she begged had you grope the back of her neck and pin the whole thing to the wall. Her arms hung down on either side of her while you thrust roughly over and over into her, slowing down to do so effectively. "Easy does it, tiger," she warned, but she fell on deaf ears before you buried your dick deeply into her.

You felt that she was... enjoying herself?

She was backing into you with each rough thrust into her. Whether or not Vixen had this ability, your Animal Imitation somehow mixed with your Pheromone Generation power, seeming to give you an unmistakeable increase in your animal magnetism; she smiled while being treated like a whore by you, and only you. You just went even faster than you did when you started, softening your blows a bit, and Mercy could feel her climax building up, so she encouraged you to just keep going. "I'm gonna cum! I'm gonna cum!"

You wanted to buy some time so you'd never get held up again, so after you warned that you were about to cum too, you channeled Parasite's power and felt his presence... Just as you did with the animals and your fellow heroes inside of you. As you finally shoot your load into her, Mercy spurted cum on your dick back, during which you grab her wrists. Sapping her energy while having her orgasm was quite the rush for you, having your own!

Now with Mercy having fallen onto the floor, still kinda alive as she laid on her side, you got up and finally found a lift to take you to the surface. You got on, pressed the up button and it took you onward and upward.
