You take command

[Warning: The story is going to get darker from her, with more boundary pushing and **** themes.]

She takes your tip in her mouth and starts the blowjob cautiously, slowly, looking up at you as if for approval. You nod and smile for the first few minutes. She gets bold enough to start to grab and softly fondle your testicles. It feels good - she's no slouch - but you'll last a while at this rate.

"Play with yourself. I want you to cum when I cum, Maria."

You think about the precise words you want to write, the effect you want to achieve, and as she blows you write on the side of her neck (knowing Maria won't notice what you write on her eyes because of your previous command):

AROUSED BY ****

You grab both sides of her head. Her eyes widen in alarm as you shove your cock deep in her mouth. She immediately starts to gag, and make muffled protests, even pushing against you uselessly with her hands and trying to resist your iron grip.

You stay deep, thrusting back and forth an inch out of her mouth, but leaving the rest of your meat to gag her, to make her barely able to breathe. Her spit and slobber increases involuntarily, a little runs out of her mouth and down her chin with each violent stroke. She looks up at you with animal panic, the visceral human reaction to being unable to breathe properly.

But there's something else too a growing heat visible in her face. Moans mingled with the **** gagging sounds.

"Shhh, Maria. Put your hands down - go back to masturbating - I know this is getting you even wetter. I know this is what you need because I know you better than you know yourself."

In the mist of mingled arousal and fear she slowly complies.

You throatfuck her for 10 more minutes, only easing up when she seems on the verge of passing out, then ramming her with full intensity again. Finally you sense, from her sounds and intensifying arm motions, that she's close. That's good because you can't hold out much longer yourself.

"I'll cum down your throat. You'll swallow it all. Then you may cum."

She grunts assent, or at least you think she does, but you don't really care. A burst of cum spews out of your cock. You pull her all the way onto you, her nose crushed into your pubes, your balls rubbing her chin, and hold her there until the spasms of your orgasm subside in her throat. She chokes and sputters and coughs as you do, but doesn't stop masturbating. It's another 10 or 20 seconds before you hear her moan in wild pleasure around your cock.

You let her slide off your cock and collapses onto her side on the floor she coughs and coughs, gasping for air. She holds her throat in one hand, feeling it as if to assure herself she can still breath. She finally steadies her breathing.

"I - I can't believe it - that felt incredible," she rasps.

Then she passes out.

It's Stacey who reacts first, rising from the floor where she had watched you as she recovered from her massive orgasm. She snatches the marker from your hand and writes on Maria's chest:

BREATHING SAFELY

SLEEPING SOUNDLY

Then looks at you.

"We need to talk, Master."
