Prove to Stacey her sub slut nature.

Stacey had written and underlined the condition of your contract - that you cannot use the marker on her or harm her - and despite your mind racing to find workarounds it had been all you could do to capture her through Maria.

But you'd come up with a plan.

You and Maria carry Stacey between you into your apartment. She's stirring, groggy, mind foggy from the unnatural effects of Maria's tongue and the hangover of massive orgasms.

Apart from your short refractory periods you'd mostly resisted enhancing your cock - you liked it the way it had been your whole adult life, but now you start to write:

12 INCHES

ADDICTIVE CUM

SUPER STUD PHEROMONES

Your cock nearly doubled in size, a huge thick monster. You feel your proportionally enlarged balls clench and churn as something inside them changes. You smell the reek of your own musk and notice Maria inhaling it in ecstasy. Not enough, not enough to give Stacey what she deserves for walking away!

ALWAYS HARD

WORSHIP OBJECT

PAIN + PLEASURE HOLE STRETCHER

You'd make her more than just beg for your cock; you'd make it her whole world. Something she'd do anything to please no matter how painful - and it would be painful. The marker wouldn't be just a glorified roleplay prop this time, it would give you control.

Stacey was awake now, babbling and begging you to let her go. Maria straddled her chest to keep her pinned. The Latina looked up at you with her piercing-studded face.

"Will you open up my pussy and make it yours, master? Your cock is so magnificent, I don't know how I didn't see it before..." Her rapturous bliss sets your blood pumping.

"I'll get to you, pet, I promise," you say.

You motion her off Stacey and pin your ex yourself. Your cock is hovering at her (wet, you notice) entrance, but you can't **** yourself into her. Damn, the contract. No matter.

"Maria, **** her to look at my cock," you say. Your pet obliges and grabs Stacey's head tight between her hands, twisting it to look at your throbbing meatstick.

Stacey babbles objections, but slowly trails off, her attention now locked on your cock.

"Stacey, tell me you want me inside you," you say.

She says nothing, just breathes harder, then clamps her mouth shut.

You wait, patiently. You have time.

"Fuuuuuuck..." she finally whispers.

"Fuck you?"

"Yes, please fuck me," she says. The words are quiet, defeated.

You ram into her and she starts to scream in pain, or in pleasure. You don't know and don't care.
