Maria succumbs

She picks a contact from her phone and makes the call. You can only hear a muffled, but excited, voice from the other end.

"Sorry I missed your calls, Michael. I need to tell you something... It's just not working out between us; we need to break up," she says.

She cringes away from her phone as a torrent of angry shouts come out from the other end. She's crying. You wrap your arms around her from behind, holding her close to you. She can surely feel your bulge against her ass. You put a hand down the front of her pants and start to gently finger her. Even as it distracts her, it strengthens her resolve too. Her breathing grows heavy, her voice throatier, her tears stop.

"I'm so sorry Michael.... No, I think it'd be better not to see each other. You can box my stuff up and I'll get someone to pick it up."

A few more words, then she hangs up the phone.

"Wh-what are you doing?"

"What do you think? A reward for your obedience, Maria."

She melts into your arms. With your free hand you reach under her shirt to grope her tits. She helps you by taking off her shirt, then her bra. You tweak her large nipples while you rub her clit, keeping a steady pace that makes her moan and squirm. She squeezes her thick thighs together. Her body is softer than Stacey's, but no less womanly. The things you could do to it - make her into a slim barbie doll, or an impossibly curvy Venus, or a celebrity clone, all run through your head. For now you just take a second to rub out the BREATHING SAFELY that Stacey had written on her chest.

It's time to push her over the edge. You grab her throat and start to squeeze.

"Trust me," you whisper, even as you tighten your grip around her throat.

The marker's magic still works, she squirms as much in arousal as discomfort, the slickness of her pussy increases.

She cums hard. Her legs stop supporting her and you let her drop to her knees. She gasps for air, but doesn't pass out - you didn't push her as far, or maybe she was more prepared.

While she recovers on her hands and knees a little post-orgasm clarity returns to her. She looks anxious, upset.

"What am I doing?" she says to herself. She scrambles to put her shirt back on, forgetting her bra.

"Sorry. This was... fun but it's crazy for me to be here. I'm going to go, I'm going to apologize to my boyfriend and forget this ever happened. Bye," she grabs her purse, turns to the door and starts to walk out.
