Time for you to get stuck in!

You stand, an unclothed vision of {if Futa==true}futanari{else}male{endif} perfection, and wait for the vault door to slowly unlock itself. As it glides open on noiseless hinges, your dick flies to attention at the sight of two beautiful girls getting each other off in mid-air. Or, more precisely, at anticipation of finally claiming the Contortionist, who has evaded you for so long.

Neither girl seems to notice as you advance into the vault, both totally lost in their love-making. Having no patience for foreplay, you stride straight up to the Latina and shove your dick deep into her pussy.

Sara tosses her head back to groan loudly at your entrance, gratefully accepting your entrance. As she dimly glances back at you, recognition glints in her eyes, and they slowly close as she murmurs, "Yes, yes it's you, I need you so bad..."

Rachel detaches from the brief mid-air threesome, floating away to pleasure herself, whilst you start pumping into the teenage thief. Her pussy is the most incredible you've ever felt - on your entrance it parts beautifully before your girth, allowing you to slide right up to her cervix, and clamping onto your shaft tightly as it tries to withdraw. Your hands move to Sara's spellbinding tits, rolling her distended nipples between your fingers, and squeezing those melons for all they're worth. With each stroke of your cock, she moans uninhibitedly, and you can feel her breasts swelling beneath her hands. C cups become Ds, then DD, then E, never stopping as long as you keep pounding. As she cums on your dick, her pleasure never abates for a moment, and her legs wrap impossibly round you as her pleasure reaches unbearable heights. Her pussy literally stretches as you will your penis to grow, her mutant body able to accommodate any size you desire - and with testosterone pumping through every one of your arteries, you desire a behemoth between your legs. With it, you impale the Latina again and again, her moans becoming half-screams echoing around the vault, her mind lost in pleasure, as you finally explode within her.

Sara shudders with every pulse of your cock, mouth open in a silent orgasmic scream as your semen inflates her belly, and a familiar gold lining grows over her eyes. You smile; Emma tells you that by fully embracing your alpha nature, and becoming the master of these slaves, the potency of your pheromones and semen have increased. Had you chosen a more virtuous path, even a full dose of cum might not have affected a mutant's mind.

"Sara Rodriguez, you will forever be my willing, horny sex ****, and take pleasure from obeying my every command, and particularly from giving me pleasure. In private, you will respond to ****, slut, whore, or any other term befitting your new station. You will be forever honest and loyal to me, and value my life and happiness beyond anything else in the world, as an addition to your personality, not a replacement. You will remain the seductress; your body will not age, will not grow sick, and recover from any injury as fast as possible. You will return to this state whenever I say the word 'freeze'. Unfreeze."

Sara finishes her orgasm, convulsing as she squirts juices from her engorged pussy, releasing shuddering breaths and a long, low moan. Rachel, now adjusted to the thick mist of pheromones, lowers your new **** to the ground, where she lays down in a seductive pose, kicking her legs into the air.

"I'm your ****, {if Futa==true}mistress{else}master{endif}." The words seem to slide from her lips like butter, as she smoulders at you, her brown eyes bold and bright. "How may I serve you?"
