Jenny is your ex-girlfriend who became your roommate three months ago when she couldn't afford her own place after the breakup. The arrangement worked surprisingly well - until last week, when she overheard you talking to your new coworker on the phone.

Now she's in the living room, mopping the floor with exaggerated concentration. You're on the couch playing video games when your phone rings again. You answer, and immediately notice her movements slow.

She turns her head, her damp hair clinging to her neck, a bead of sweat rolling down her throat 'Who's that?' Her voice sounds casual but her grip tightens on the mop handle until her knuckles turn white 'Don't tell me you're seeing someone new already.' She stands up straight, her thin white tank top completely transparent now from sweat, nipples clearly visible through the fabric

She takes a step toward you 'I'm just curious,' she says, though the way she's biting her lower lip gives her away 'What's she like?'
